I desse søknadstider kan det vere interessant å orientere seg i forhald til ulike kanalar for å formidle vitskap – antan det er til ekspertar eller populærvitskapleg formidling. Eit døme på det siste kan du finne i denne lydmontasjen ( podcast), kor Vidar Jensen gir ei enkel innføring i Idélab-prosjektet sitt. Dersom du også vil ha bilete til forteljinga, kan du ta nettlesaren hit.
Carbon capture technologies are expected to play an important contribution in the efforts to reduce the environmental impact of the use of fossil fuels. One approach to remove carbon dioxide from gas mixtures is its adsorption on nanoporous materials, such as zeolites and metal-organic frameworks. Among the latter, the CPO-27 series of compounds has been widely investigated because of its extraordinary properties for capturing carbon dioxide. Now, using the state-of-the-art equipment available at the Swiss-Norwegian Beamlines (SNBL) at the European Synchrotron Radiation Facility (ESRF), Pascal Dietzel and his team from have investigated with unprecedented time resolution how carbon dioxide is incorporated into the crystal structure of the host framework. Read the full paper here or just watch a video of the CO2 molecules occupying their crystallographic positions as a function of temperature.
Applying NMR spectroscopy and Magnetic Resonance Imaging, researchers at our department (Christian Totland, John Georg Seland and Willy Nerdal) and at Høgskulen på Vestlandet (Signe Steinkopf) document how reduction in marine omega-3 in farmed salmon affects salmon fillet features, right down at the molecular level. The study shows that carbon magnetic resonance spectroscopy direct on the fish meat can quantify the most relevant fatty acids within 40 minutes without the use of chemicals such as chloroform. In 1990, omega-3 in farmed salmon was predominantly marine fatty acids while there are now roughly equal levels of omega-3 from plants and marine sources. MR images show differences in texture between wild and farmed salmon, where wild salmon have narrower lines of fat tissue compared to farmed salmon. In addition, the muscle tissue of farmed salmon shows buildup of fat, known as marbled fat. The softer consistency of farmed salmon can be viewed in conjunction with fat profile.
In the past 20 years, metal-organic frameworks (MOFs) have become one of the most active areas of research within inorganic chemistry. EurJIC is acknowledging the rapid development with a Cluster Issue on «MOFs Heading Towards Application». Our own Pascal Dietzel and Hiroshi Kitagawa from the University of Kyoto are guest-editing this issue, which contains more than thirty papers spanning the breadth of current activities in the leading research groups in the field.
As many will know, Chenchen Lin successfully defended her PhD thesis last week. Her work forms part of the research effort of professor Kvalheim and coworkers, within metabolomics. An important application is within the treatment of obesity, and Chenchen’s findings in this respect were recently featured in Vestlandsrevyen!
Kjemisk institutt sitt nye publikasjonsgalleri blei i dag høgtideleg opna av nestleiar Haug i nærver av mange interesserte kollegaer (Takk for oppmøtet :-)!
Her vil du få eit overblikk over forskningstema ved instituttet og samstundes kunne følgje utviklinga i den vitskaplege produksjonen vår.
Galleriet vil bli komplettert med fleire artiklar så snart underteikna mottek dei (i form av pdf) frå forfattarane. Artiklane må ha sidetal og volumnummer før dei blir hengt opp. Og ja: vi arbeider med å få på plass betre lyssetting.
Congrats to Ole Johan and his co-authors for making it to the front page with their paper on Growing with dinosaurs: natural products from the Cretaceous relict Metasequoia glyptostroboides Hu & Cheng—a molecular reservoir from the ancient world with potential in modern medicine.
