��Ѹ��Դ��߿�Ƭ of Lethbridge C-CRAFT symposium to showcase power of fluorine and NMR spectroscopy

trevor.kenney — Fri, 05 Dec 2014 19:00:32 +0000

The first centre of its kind in Canada, the ��Ѹ��Դ��߿�Ƭ of Lethbridge’s Canadian Centre for Research in Advanced Fluorine Technologies (C-CRAFT), presents a Symposium Celebrating NMR Spectroscopy and Fluorine Chemistry, Friday, December 5, from 1 to 5 p.m. at the U of L.

With plenary speakers Dr. Jean-François Paquin (Université Laval) and Dr. Klaus Schmidt-Rohr (Brandeis ��Ѹ��Դ��߿�Ƭ) joining world-class researchers within C-CRAFT, the symposium will examine various applications of the element fluorine and nuclear magnetic resonance (NMR) spectroscopy.

“C-CRAFT is the first Canadian centre focusing on research and training around the element of fluorine and brings together a unique team of researchers with a wide range of expertise,” says Dr. Michael Gerken, a professor in the Department of Chemistry and Biochemistry and the director of C-CRAFT. “While we were formalized as a centre nearly one year ago, this symposium is somewhat of a launch event for C-CRAFT.”

Fluorine is a unique element because of its reactivity in the elemental form and the large number of applications of fluorine compounds. For example, it has been estimated that 20 per cent of pharmaceuticals on the market contain fluorine and 30 to 40 per cent of agrochemicals contain fluorine.

“Fluorine chemistry is definitely a strength that is unique to the ��Ѹ��Դ��߿�Ƭ of Lethbridge, and this centre is a way to build on that strength by getting together scientists who are interested in this chemistry in order to share knowledge, conduct research together and to provide services and expertise that are helpful to industry,” says Gerken.

The symposium will feature a host of talks throughout the afternoon, beginning with Paquin’s address at 1:10 p.m. when he presents Revisiting the Use of Fluoride as a Leaving Group. The U of L’s Dr. Stacey Wetmore follows at 1:50 p.m. as she presents Using Fluorine to Understand DNA Damage. At 4:20 p.m., Nora Foroud and Jim Miller of the Lethbridge Research Centre – Agriculture and Agri-Food Canada present NMR Resolutions of Agricultural Traits: From Soil Chemistry to Crop Health.

“Since the centre was opened, we have added a 700 MHz NMR spectrometer, thanks to $1.6 million of funding through the Canada Foundation for Innovation, the Alberta Government and the U of L,” says Gerken. “NMR spectroscopy is a powerful technique that allows for even more in-depth study of fluorine compounds and can be used in trans-disciplinary studies by researchers of various departments at the U of L and from other universities, research institutes and industry.”

C-CRAFT and the magnetic resonance facility at the U of L are already gaining a reputation as the hub for fluorine researchers across Canada and worldwide to collaborate with each other and share their expertise on fluorine and NMR spectroscopy for areas such as pharmaceuticals, agrochemicals, plastics, oil production, biochemistry and neuroscience.

The symposium, to be held in C640, features a total of eight presentations.

Efficient and cleaner oil production could result from Hazendonk, U of L research

trevor.kenney — Thu, 12 Dec 2013 17:28:26 +0000

A new discovery by ��Ѹ��Դ��߿�Ƭ of Lethbridge researchers that sheds light on a complex chemical structure found in bitumen may enable companies working in Canada’s oilsands to operate more efficiently and reduce their environmental footprint.

Dr. Paul Hazendonk is a research with the U of L’s Canadian Centre for Research in Advanced Fluorine Technology (C-CRAFT).

Three members of the Department of Chemistry and Biochemistry at the U of L, in collaboration with a private sector oilsands researcher, have established the architecture of asphaltene, the heaviest element in bitumen. Asphaltene has been found to interfere with the processes for extracting and upgrading crude oil.

The finding makes it possible to develop more effective and cleaner techniques for pumping and refining synthetic crude. The research, which took place at the ��Ѹ��Դ��߿�Ƭ’s specialized Magnetic Resonance Facility, was published in the November/December 2013 edition of Energy & Fuels, one of the most cited journals in oil chemistry research.

“Asphaltenes throw a wrench into oilsands production, because they cause the oil to become very thick and viscous, and hard to treat chemically. By knowing their structure, it becomes possible to develop processes to break them down or modify them,” says Dr. Paul Hazendonk, a researcher with the U of L’s Canadian Centre for Research in Advanced Fluorine Technology (C-CRAFT).

Oilsands production could benefit greatly from the results of this U of L research.

Asphaltenes are highly complex molecular structures made up primarily of carbon, hydrogen, nitrogen, oxygen and sulfur, as well as heavy metals such as nickel, iron and vanadium. In crude oil, asphaltene often forms into clusters that can block well bores, plug pipelines and deactivate catalysts that are used to refine it. As well, the presence of asphaltenes in petroleum significantly degrades fuel performance.

After two years of intensive research using nuclear magnetic resonance spectroscopy, the scientists were able to gain an in-depth understanding of the physical and chemical nature of asphaltenes, including the inter-molecular interactions that precipitate these troublesome clusters.

The finding has significant implications for oilsands companies looking to boost their productivity and stay competitive in this increasingly important segment of the Canadian economy. According to industry statistics compiled by the Alberta government, the region contains the third-largest crude oil reserve in the world.

In addition to potential productivity benefits, this research could help the industry lessen its impact on the environment. Currently, producing 100 barrels of synthetic crude requires a minimum of 20 barrels worth of oil equivalent in energy (from extraction, processing, upgrading, transportation and waste remediation), which equals 3.3 tons of oil that causes 10 tons of carbon dioxide emissions. By contrast, conventional oil has a ratio of 100 to 3.3 barrels, which equals 550 kg of oil that leads to 1.5 tons of CO2. If oil companies can develop better production processes, they will be able to operate more sustainably.

“If we can improve processes to make that ratio much better, that reduces the greenhouse gas emissions of the industry,” says Hazendonk, who is currently conducting new research with his team members to further explore asphaltenes. “So operations become leaner, more cost effective and more efficient from an energy usage point of view.”

The Canadian Centre of Research in Advanced Fluorine Technologies is the first Canadian centre focusing on research and training around the element fluorine. C-CRAFT brings together local, national and international teams with wide ranges of expertise in fluorine chemistry.

SPIRE earns international award

trevor.kenney — Fri, 19 Jul 2013 22:20:47 +0000

A ��Ѹ��Դ��߿�Ƭ of Lethbridge physics research team and a Lethbridge-based high tech data processing company are among the collective group of people behind the Herschel Space Telescope's Spectral and Photometric Imaging Receiver (SPIRE) instrument, which has been awarded the prestigious 2013 Sir Arthur Clarke Award for academic study and research.

The award is in recognition of the scientific achievements of the SPIRE instrument, which was designed, built and operated by an international team of astronomers, scientists and engineers.

SPIRE was co-developed by Dr. David Naylor (physics and astronomy) and a team of researchers who led Canada's contribution to the Herschel project on behalf of the Canadian Space Agency.

Blue Sky Spectroscopy, a Lethbridge-based, high tech company, is one of the three international Data Processing and Science Analysis Software centres for the SPIRE instrument. The mission, launched on May 14, 2009 from the Ariane Spaceport in French Guyana, almost immediately began to shed new light on stars and galaxies by measuring a level of light called far-infrared.

Over a four-year mission period, Herschel -- the largest, most powerful infrared telescope ever flown in space -- made extraordinary discoveries across a wide range of topics, from starburst galaxies in the distant Universe to newly forming planetary systems orbiting nearby young stars. SPIRE is one of three devices attached to the Herschel telescope system.

"SPIRE detects heat and chemical signals that are not visible by optical telescopes, and turns that data into the amazing images and information we and other scientists are using to learn more about the life and death of stars and galaxies," says Naylor.

In addition to literally 'clearing up' the images people have been using for two centuries to look into space, Naylor said the Herschel mission is confirming the existence of molecules on earth that originated in space.

"With SPIRE we can look at the big picture, or the very tiny picture, and gain a whole new insight into how stars live and die. The reason the imagery is so clear is that the space observatory sits more than 1.5 million km from earth, far from our atmosphere, which absorbs virtually all radiation at which far-infrared wavelengths travel. Since the universe emits most of its energy at these wavelengths, Herschel provides us with our first comprehensive view of the universe."

The data and crisp images come from a device about as big as a large microwave oven that took more than 15 years and $100 million to develop – and has to function at a chilly -270C. Herschel operated until the end of its scientific mission on Apr. 29, 2013.

A multi-year data analysis period is now taking place.

The award was collected on behalf of the team by Tanya Lim, of the UK-based STFC Rutherford Appleton Laboratory.

"A lot of people from both science and engineering disciplines have dedicated up to 15 years of their lives of making SPIRE a scientific success," says Lim. "It is wonderful that we can all share in this award and we are very grateful for receiving it."

The UK team is led by Naylor's colleague Matt Griffin, of Cardiff ��Ѹ��Դ��߿�Ƭ, Wales.

"Building and operating SPIRE has taken many years of effort by a lot of very talented people in our multi-national team. They are rightly proud of the scientific success of Herschel and SPIRE, and they are delighted to win this award."

The Sir Arthur Clarke awards are presented annually in recognition of notable or outstanding achievements in, or contributions to, all space activities. They are organized by the Arthur C Clarke Foundation and the British Interplanetary Society, and this year were presented during the conference dinner at the UK Space Conference in Glasgow, Scotland.

The full list of 2013 winners are available on the British Interplanetary Society website.

This is the second Sir Arthur Clarke Award for the SPIRE team, with Matt Griffin receiving the award for individual achievement in 2010.

Herschel Mission Operating Phase Wrapping Up

trevor.kenney — Mon, 11 Mar 2013 15:54:37 +0000

A pioneering space imaging mission that sent a scientific instrument co-developed by a U of L researcher on a 1.5 million kilometre trip to deep space aboard the Herschel Space Observatory might be nearing its conclusion, but that doesn't mean the end of the project for the research team.

Dr. David Naylor (Physics and Astronomy) and his team of researchers lead Canada's contribution to the Herschel project on behalf of the Canadian Space Agency.

The instrument, called the Spectral and Photometric Imaging Receiver ("SPIRE"), is one of three devices attached to the Herschel telescope system.

http://www.asc-csa.gc.ca/eng/satellites/herschel/default.asp

The helium-filled 'gas tank' cooling Herschel's equipment is expected to run dry over the next few weeks – an expected process.

As the coolant diminishes, equipment will stop working, but data transmission will continue until the bus-sized telescope parks itself in a permanent orbit around the sun.

What follows is a five-year post operation phase, where the data obtained during the mission are used to develop improved calibration algorithms to allow the most information to be extracted from the images. Eventually the data will be reprocessed and placed in an archive that will have legacy value.

http://www.esa.int/Our_Activities/Space_Science/Herschel_to_finish_observing_soon

The mission, launched on May 14, 2009 from the Ariane Spaceport in French Guyana, almost immediately began to shed new light on stars and galaxies by measuring a level of light called far-infrared.

Infrared light is invisible to the human eye, but travels well across the universe. Star forming regions emit light at these wavelengths and Herschel can detect it, capturing a wealth of detail such as heat signatures and chemical composition that help astronomers clearly see, for the first time, stars and whole galaxies that have previously remained hidden or only poorly understood.

"SPIRE picks up heat and chemical signals that are not visible by optical telescopes, and turns that data into the amazing images and information we and other scientists are using to learn more about the life and death of stars and galaxies," Naylor said.

In addition to literally 'clearing up' the images people have been using for two centuries to look into space, Naylor said the Herschel mission is confirming the existence of molecules on earth that originated in space.

"With SPIRE we can look at the big picture, or the very tiny picture, and gain a whole new insight into how stars live and die. The reason the imagery is so clear is that the space observatory sits more than 1.5 million km from earth, far from our atmosphere which absorbs virtually all radiation at which far-infrared wavelengths. Since the universe emits most of its energy at these wavelengths, Herschel provides us with our first comprehensive view of the universe."

The data and crisp images come from a device about as big as a large microwave oven that took more than 15 years and $100 million to develop – and has to function at a chilly -270C.

Also gratifying are the unique research collaborations that Naylor sees happening in the future. "Approximately one-third of the time available to researchers is guaranteed to those involved in key projects, and our time is included in that. We see the data here in Lethbridge before anyone else does. Scientists will be seeking our help in analyzing their data and the U of L group will be an important Canadian and international resource."

With an estimated output of up to 7,000 hours per year of data, there should be enough information to keep researchers busy for years – and some of that data flows through Blue Sky Spectroscopy, a Lethbridge-based, high tech spinoff company founded by Naylor in 2003, and now privately owned and operated.

Blue Sky is one of the three international Data Processing and Science Analysis Software centres for the SPIRE instrument. Data are downloaded daily from the spacecraft and stored on the Blue Sky servers.

Its highly qualified staff, all with postgraduate degrees, specialize in custom hardware and software spectroscopic solutions. Customers include NASA, ESA, and CSA, and many leading research institutes such as Harvard, Berkeley, Chicago, Max Planck and Cardiff, NIST, Centre d'Etudes Atomique, Paris, Institute National d'Optique, Canada to name a few.

What's next?

According to Naylor, more research that refines his current SPIRE device to make it suitable for yet another space mission currently under review by the Japanese, European and Canadian Space Agencies.

The project – SPICA, which stands for Space Infrared Telescope for Cosmology and Astrophysics – is a next-generation version of the SPIRE device, and would perform a similar function on a space telescope planned to launch in 2022.

Learn more about the SPICA project, here: http://research.uleth.ca/spica/index.php

Naylor said Herschel has been an overwhelming success, but its sensitivity is limited by its 'warm' telescope. "At a temperature of -80K (-193C) this may sound cold, but it limits the achievable sensitivity. By cooling a telescope to -6K (-267C) would increase the sensitivity by an astonishing factor of 100, allowing it to explore a volume of space 1000x greater than Herschel".

Building on the success of Herschel, the Japanese Space Agency JAXA is developing such a cooled telescope. ESA has joined forces with JAXA; in return for ESA providing the telescope and a ground station, European scientists will build one of the flight instruments.

Based on the Herschel experience, an imaging FTS similar to the ones Naylor's group has been building for over two decades has been selected and Naylor has been invited to join the international team that will build the instrument known as SAFARI.

The instrument is similar to one that the U of L team has recently commissioned on the James Clerk Maxwell Telescope, the world's largest submillimetre telescope located atop Mauna Kea, Hawaii.

The space-based project, SPICA – which stands for Space Infrared Telescope for Cosmology and Astrophysics – is a next-generation version of the SPIRE device, and would perform a similar function on a space telescope planned to launch in 2022.

In Alberta, a recent and significant collaboration has also been launched with the ��Ѹ��Դ��߿�Ƭ of Calgary, where the U of L and the U of C and Athabasca ��Ѹ��Դ��߿�Ƭ have formed the Institute for Space Imaging Science (ISIS) to work together on projects that take space research further than Herschel technology, whether on the ground or in the atmosphere.

"By nature, physics researchers don't get too excited, but to see these images and know that we're looking at them in a whole new way, and further that we'll be able to share this information with the public so they can learn about the origins of the universe, is truly exciting," Naylor said.

He estimates that more than 200 papers have already been produced using data from the Herschel mission, and approximately half of those have Canadian co-authors.

The geographical distribution of SPIRE science within Canada is broad with authors affiliated with the following universities/institutions: UBC, Calgary, CFHT, HIA/UVic, Laval, Lethbridge, McMaster, Toronto, Waterloo. As well, a large group of researchers, including more than 30 post docs, undergrad and grad students have conducted research using SPIRE data.

An example of the type of imaging and discoveries made possible by the Herschel Space Observatory can be found here:

Comet 'Demolition Derby' Creates New Information About Solar System Origin

Compelling new images from the Herschel Space Telescope – parked more than 1.5 million kilometres from earth and facing into deep space -- are showing researchers what the formation of our solar system must have looked like at its early stages: a violent, comet-laden disk of debris where thousands of 1 km wide chunks of ice collide and spin around a young star.

http://oshi.esa.int/#list=/images.html?q=pillars;detail=image.html?id=89

The images are made possible in part by technology created by ��Ѹ��Դ��߿�Ƭ of Lethbridge researchers, and designed and built by an international consortium of space agencies, universities and research institutes.

Pioneer Holmes looks back at ��Ѹ��Դ��߿�Ƭ's beginnings

trevor.kenney — Thu, 19 Jan 2012 23:49:33 +0000

A chemist, teacher, and university administrator, Dr. Owen Holmes (LLD '05) helped shape the character of the ��Ѹ��Դ��߿�Ƭ of Lethbridge as a liberal arts institution.

Holmes began his career as a research chemist, making significant discoveries in electron spectroscopy, before turning to teaching and administration on the Regina campus of the ��Ѹ��Դ��߿�Ƭ of Saskatchewan. He later moved to the Lethbridge Junior College, where he became acting principal, and then Dean of the Academic Section and Professor of Chemistry. When the Academic Section of the college became the nucleus of the ��Ѹ��Դ��߿�Ƭ of Lethbridge, Holmes was the institution's first dean of Arts and Science. He went on to become the vice-president (academic) of the U of L, in which capacity he served for a decade.

As an academic leader of the ��Ѹ��Դ��߿�Ƭ of Lethbridge, he infused the academic and administrative sides of the institution with the philosophy of liberal education. His great achievement was to create a successful liberal education program, the first in western Canadian post-secondary education and an approach that was less than popular at the time.

Many of the ideas Holmes implemented - liberal arts education, small class sizes, independent research opportunities, and student-professor interaction - have shaped the unique character of the U of L and have persisted in the institution to this day.

Holmes's leadership and vision contributed immensely to the success of the fledgling ��Ѹ��Դ��߿�Ƭ of Lethbridge, and he has dedicated much of his career to creating and consolidating the U of L's reputation of academic excellence.

As he neared retirement, Holmes embarked on a new career as an archivist for the U of L and the City of Lethbridge. When he retired from the ��Ѹ��Դ��߿�Ƭ of Lethbridge, he continued to serve in educational and social service agencies in Lethbridge.

SPIRE takes detailed look at giant star

trevor.kenney — Mon, 07 Dec 2009 21:42:37 +0000

New images and data from an instrument attached to the groundbreaking Herschel Space Observatory, and co-designed by a ��Ѹ��Դ��߿�Ƭ of Lethbridge team, are showing off even more detail about the origins of the universe including previously-undiscovered information about a giant star more than 5,000 light years away that could soon explode as a supernova.

Physics and Astronomy researcher Dr. David Naylor, Head of the Space Astronomy Division of the Institute for Space Imaging Science at the ��Ѹ��Դ��߿�Ƭ of Lethbridge and his team of researchers lead Canada's contribution to the Herschel project on behalf of the Canadian Space Agency.

He co-designed an instrument that is called the Spectral and Photometric Imaging Receiver ("SPIRE"), and is one of three devices attached to the Herschel telescope system.

"SPIRE detects radiation emitted at very long wavelengths, well beyond the limit of human eye. These wavelengths probe a different part of the universe, one that cannot be studied with optical techniques," Naylor said.
"This allows us to study two unique areas of astronomy: the very coldest parts of the universe where stars are born, and the very distant universe. Taken together this information provides a better picture of how stars and galaxies evolved over cosmic time."

The Herschel team recently turned the observatory's attention to a large star approximately 5,000 light years from earth called VY Canis Majoris, in the final stages of 'death' and got many surprising results,– the key one being an excess of water in the readings.

"VY Canis Majoris is about 2600 times as big as our sun and about 100,000 times as bright," Naylor said. "To put it in perspective if the earth were orbiting this star it would have already been consumed by the dying star, which is now larger than the orbit of Saturn. The giant star would vapourize all material in its path as it expanded, not just ices and oceans but rock itself."

While the Herschel images are spectacular and offer a complementary view to those provided by optical telescopes such as Hubble, Naylor said it is only through spectroscopy that one can identify the molecules present in these sources.

"With SPIRE we can look at the big picture, or the very tiny picture, and gain a whole new insight into how stars live and die. The reason the imagery is so clear is that the space observatory employs the largest mirror launched to date and that the observatory sits more than 1.5 million km from earth, far removed from the effects of the earth's atmosphere."

Building on the success of Herschel and with support from the CSA, Naylor is championing a Canadian role in the SPace Infrared telecope for Cosmology and Astrophysics (SPICA). SPICA a Japanese/European space agency mission is similar to Herschel but promises to be an astonishing factor of 100 times more sensitive! Worldwide, this project involves research teams in the Netherlands, Belgium, France, Germany, Greece, Spain, Switzerland, UK.

In Alberta, a recent and significant collaboration has been launched with the ��Ѹ��Դ��߿�Ƭ of Calgary and Athabasca ��Ѹ��Դ��߿�Ƭ, where several researchers have formed the Institute for Space Imaging Science (ISIS) to work together on projects that take space research further than Herschel technology, whether on the ground or in the atmosphere.

The imaging power of the SPIRE instrument on Herschel spacecraft is a major leap forward in our ability to explore the Universe, says ��Ѹ��Դ��߿�Ƭ of Calgary Professor Russ Taylor, Director of ISIS. SPIRE is a prominent example of Albert leadership in the development of advanced technology for Space.

As well, Blue Sky Spectroscopy, a local high tech spin off company founded by Naylor in 2003, and now privately owned and operated, has been the data processing centre for the data from the SPIRE spectrometer.
Blue Sky has been key in processing data in the most accurate way possible to allow astronomers to make the best use of the SPIRE spectrograph. Seeing the first accurately calibrated spectra of astronomical targets has been the reward for many years of hard and diligent work. The Canadian Space Agency has committed to support this effort throughout the lifetime of the instrument.
