Academics recreate supernova reaction in a lab
Researchers in Surrey's Nuclear Physics Group have collaborated with TRIUMF National Laboratory (Canada) to achieve the first direct measurement of a supernova reaction in a laboratory using an accelerated beam of radioactive nuclei......»»
New research shows how companies could be gaming their reported greenhouse gas emissions
New research by academics at King's Business School has shown that companies are able to "game" their reported greenhouse gas emissions to an extent that is both financially and environmentally material because of the discretion they have around the.....»»
Ascertaining distances for supernovae that struck the Earth 3 million and 7 million years ago
A study, released on the pre-print server arXiv, examines how the Earth was hit by blasts from supernovae (plural form of supernova (SN)) that occurred 3 million years ago (Mya) and 7 Mya with the goal of ascertaining the distances of where these bla.....»»
Study suggests the introduction of multi-cations contributes to the performance of anion exchange membranes
Anion exchange membrane fuel cells (AEMFCs) have gained attention in the process of fuel cell development because they operate in alkaline environments, the redox reaction rate at the electrodes is faster, and non-precious metal catalysts such as Ni,.....»»
Observations explore the properties of Type Ic supernova SN 2022jli
An international team of astronomers has performed multi-wavelength photometric and spectroscopic observations of a recently discovered Type Ic supernova known as SN 2022jli. Results of the observational campaign, published September 22 on the pre-pr.....»»
Researchers investigate role of water molecules in formation of condensates in cells
In order to fulfill their function, biological cells need to be divided into separate reaction compartments. This is sometimes done with membranes, and sometimes without them: the spontaneous segregation of certain types of biomolecules leads to the.....»»
Hubble investigates the gorgeous remnants of a supernova
Scientists are using data from Hubble data of the famous Cygnus Loop supernova remnant to study how these remnants change over time......»»
Saturday Citations: Volcano vs. asteroid; NASA"s supernova time lapse; immortal chemicals
This week, we're highlighting a study involving toxic chemical contaminants, and just for fun, a second study involving other toxic chemical contaminants. But NASA made a cool time-lapse video using the good old Hubble space telescope, and a group of.....»»
Living on the edge: Supernova bubble expands in new Hubble time-lapse movie
Though a doomed star exploded some 20,000 years ago, its tattered remnants continue racing into space at breakneck speeds—and NASA's Hubble Space Telescope has caught the action......»»
New study finds that microfinance is exacerbating climate precarity and harm in Cambodia
A recent paper co-authored by King's academics argues that microfinance, often projected as a means of coping with climate risk, in fact contributes to farmers in Cambodia being in greater debt and more vulnerable to climate change......»»
Teams investigate material degradation process of carbon-based catalyst
Although a plethora of carbon-based catalysts have been developed to promote oxygen reduction reaction (ORR) in different electrochemical systems, the degradation process of those catalysts remains obscure to date. During certain steps of the ORR on.....»»
Extreme weight loss: Star sheds unexpected amounts of mass just before going supernova
A newly discovered nearby supernova whose star ejected up to a full solar mass of material in the year prior to its explosion is challenging the standard theory of stellar evolution. The new observations are giving astronomers insight into what happe.....»»
Researchers describe advances in mass spectrometry analysis to improve identification of glycopeptides
Glycosylation is the attachment of carbohydrates to the backbone of a protein through an enzymatic reaction. It plays a critical role in determining protein structure, function and stability. A protein that is glycosylated is known as a glycoprotein......»»
Electromagnetic field-assisted thermal catalysis enabling low-temperature, low-pressure, large-scale ammonia synthesis
Ammonia (NH3), as one of the most common industrial chemicals, is essential for nitrogenous fertilizer production and shows potential as a next-generation green fuel. Industrial ammonia synthesis relies on the reaction of fossil fuel-derived hydrogen.....»»
Iron-based molecular switch improves reaction yield by modulating zeolite catalyst acidity
A molecular switch, or molecule that changes in response to varying environmental stimuli, has successfully modified the acidity of a zeolite catalyst to improve the yield of paraxylene from methanol in heterogeneous catalysis, or a reaction where th.....»»
Team reviews photocatalysis for methane conversion to high-value products
A research team has published a review paper summarizing the recent progress in methane conversion using photocatalysis. Photocatalysis, the process of using light to accelerate a chemical reaction, offers a promising and green technology for methane.....»»
Direct synthesis of fluorinated carbon materials via solid-state mechanochemical reaction between graphite and PTFE
A research team, led by Professor Jong-Beom Baek and his team in the School of Energy and Chemical Engineering at UNIST have achieved a significant breakthrough in battery technology. They have developed an innovative method that enables the safe syn.....»»
Idea of green growth losing traction among climate policy researchers, survey of nearly 800 academics reveals
When she took to the floor to give her State of the Union speech on 13 September, European Commission president Ursula von der Leyen largely stood by the script. Describing her vision of an economically buoyant and sustainable Europe in the era of cl.....»»
Final Fantasy 7 Rebirth: Reaction to demo as Tokyo Game Show starts
It's one of the biggest game releases of next year - and verdicts are rolling in on the first demo......»»
New Type I supernova discovered with JWST
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed the galaxy cluster PLCK G165.7+67.0. The observational campaign resulted in the detection of a new Type I supernova. The finding is reported in a paper pub.....»»
