    Comparison of energy sources and transport alternatives using life cycle assessment.

    On Friday Aug 14 at 10.15, Jørgen Gausdal Jacobsen delivers his trial lecture for the PhD degree, with the title Comparison of energy sources and transport alternatives using life cycle assessment. 

    Location ZoomThe meeting is set up with a waiting-room function due to the security regulations for ZOOM meetings. The moderator gives access to the participants manually. The entrance closes when the lecture starts. Therefore, please, log into the meeting a few minutes before 10.15. Welcome!

    Abstract: The search for energy sources with higher energy efficiency and lower environmental impact has increased rapidly in recent years. This has led to the development of new approaches to calculate the net energy gain of different energy sources and transport alternatives. In the lecture key factors such as energy payback ratio, energy efficiency, sustainability, etc. are introduced and defined. These parameters will be used to compare life cycle energy gain and consumption for different energy sources including a discussion of CO2 footprint, degree of renewability and sustainability. Specifically, power sources such as hydro, wind and solar will be compared to hydrocarbon gas and coal. The lecture will be assessed by Tore Skodvin (leader), Tanja Barth og Bjarte Holmelid.

    Cecilie hjelper barista og promoterer kjemi

    Som kjemikarar er vi godt kjent med at den molekylære samansetjinga til ei prøve er avgjerande for både fysikalske, kjemiske og sensoriske eigenskaper. Denne forståinga er ikkje like godt etablert i samfunnet ellers, og det var derfor gledeleg at Barista-Christian vende seg til Kjemisk institutt for å få innsikt i den kjemiske samansetjinga av mesterskapskaffien som han var så stolt over. Cecilie tok i mot utfordringa, og resultatet var både ein flott promoteringsvideo for kjemi, og ei sølvmedalje i Barista-NM for Christian. Så er det framleis eit stykke fram til det å utvikle den beste kaffien på basis av kjemiske analysar… Takk til kommunikasjonsgjengen på MN-fakultetet!

    Sometimes you have to cool down to become ‘HOT’

    Metal-organic frameworks (MOF) are typically microporous materials (i.e. with pore diameter < 2 nm), and their properties in respect to gas adsorption and separation processes have been much investigated. One of the most interesting MOF materials for a number of sorption processes, e.g. hydrogen purification or storage at low temperature, methane storage at high pressures, or carbon dioxide capture, is the CPO-27 series of materials, in whose development Prof. Pascal Dietzel from our department had a pioneering role. One of his specialties is the use of in situ X-ray diffraction measurements to study the host-guest structures of gases adsorbed in the porous materials. The research group had studied CO2 adsorption on CPO-27 in the past, by cooling samples in 1 bar CO2 from 453 to 195 K. Usually, one wouldn’t cool below the sublimation temperature of CO2 in the experiment because the pores are full with CO2 at that temperature. However, the CO2 adsorbed on the metal cation of the MOF is known to perform a precession movement that affects the crystal structure determination, so Dietzel and co-workers decided to cool the sample further to see whether the adsorbed molecule gets locked in a more defined position at lower temperatures. This wasn’t the case, but instead they observed a phase transition in CO2 loaded CPO-27-Co and Zn below 110 K, in which the inorganic chains and the organic ligands of the framework collectively rearrange into a distorted superstructure of the original honeycomb-resembling structure. The paper is being featured with free access for 6 weeks in the quarterly HOT article collection of CrystEngComm, which represents the top 10% of interesting and significant research for this community. We congratulate!

    Congrat´s Dr Henrik!

    Last Tuesday, Henrik Nicolay Sørgård defended, successfully and with great stamina, his thesis «Wetting in Porous Media: A Nuclear Magnetic Resonance Study» for the degree of ph.d. Stamina was surely needed, because only rarely has an opponent met better prepared than in this case — the number of well-designed slides exceeded 60. Congratulations are in order, and Henrik will surely enjoy his best summer vacation in years!

    Fægriprisen 2020

    Alle artikler som sendes inn til tidsskriftet Naturen i perioden 1. september 2019 til 31. august 2020, er med i konkurransen om Fægriprisen 2020. Fægriprisen er en forfatterpris som oppmuntrer til god, skriftlig populærvitenskapelig formidling innenfor naturvitenskapelige fag. Vinnere av Fægriprisen 2020 blir kunngjort i desember.

    Prisen har to kategorier: Hovedprisen har vi valgt å kalle Fægri’s minnepris for populærvitenskapelig formidling i tidsskriftet Naturen  (forkortet til Fægriprisen), og er på 10 000 kr. Den andre kategorien er for studenter (også Ph.D.-studenter!), er på 5000 kr, og har fått navnet Fægri’s studentpris for beste populærvitenskapelige artikkel i tidsskriftet Naturen (forkortet Fægri’s studentpris). Vi, dvs. redaksjonen i Naturen, håper med dette at potensielle forfattere vil være med å konkurrere om Fægriprisen 2020. Spesielt er det et stort ønske om artikler innen kjemiske tema! Vinnerne av prisen vil bli kunngjort av tidsskriftet Naturen og Universitetsforlaget. Forfatterveiledning finnes på Naturen’s hjemmeside.

    Nanoday is Today!

    Have you ever visited an online poster session before? Today is your chance, when this year’s Nano100 students present their posters. The exhibition is open already, but the poster session with the presentees available to explain and elaborate starts at 1130 (waiting room opens at 1120). Welcome to all, and congrats to this year’s Nano100 students!

    Kavli prize in nanoscience awarded

    Today, the Kavli prizes for 2020 was awarded. Chair of the award committee for nano science, our colleague at the Physics department, professor Bodil Holst, had the honour of announcing the four winners.

    This years winners receive the award because of their work to develop very accurate and aberration-corrected lenses for focusing electrons, thereby developing transmission electron microscopy (TEM) and scanning TEM to sub-ångström resolution.
