Trapping gases better with boron nitride "nanopores"
What is common between a technology for storing energy in a solar cell and that for water purification? They both rely on the use of porous materials, or more specifically, 'nanoporous' materials that can trap gas molecules within narrow spaces on th.....»»
Monolayer hexagonal boron nitride can extend plasmonic enhancement limit
A research team led by Prof. Yang Liangbao from Hefei Institutes of Physical Science, Chinese Academy of Sciences found that hexagonal boron nitride (h-BN) could effectively block electron tunneling and extend the ultimate plasmonic enhancement limit.....»»
A particular "sandwich" of graphene and boron nitride may lead to next-gen microelectronics
Moiré patterns occur everywhere. They are created by layering two similar but not identical geometric designs. A common example is the pattern that sometimes emerges when viewing a chain-link fence through a second chain-link fence......»»
Salting and burying biomass crops in dry landfills could economically capture greenhouse gases for thousands of years
Reducing global greenhouse gas emissions is critical to avoiding a climate disaster, but current carbon removal methods are proving to be inadequate and costly. Now researchers from the University of California, Berkeley, have proposed a scalable sol.....»»

Breaking the barrier: Low-temp ammonia synthesis with iron catalysts and barium hydride
The Haber-Bosch (HB) process is one of the most important industrial chemical reactions. It combines nitrogen and hydrogen gases in the presence of an iron-based catalyst at high temperatures and pressures to produce ammonia fertilizer which helps pr.....»»
"Critical tool" launched to track national contributions to climate change
Research published today shows how countries have contributed to global warming through their emissions of key greenhouse gases since 1850—marking a new effort to track impacts in a critical decade for climate policy......»»
How Vietnam is trying to stop rice warming the planet
As a child, Dong Van Canh watched while the rice fields of Vietnam's Mekong Delta were set alight to make way for the next crop, blackening the sky and flooding the air with potent greenhouse gases......»»
The journey of a carbon atom: From space, NASA"s PACE mission detects carbon in the sky, land and sea
Whether in plants or animals, greenhouse gases or smoke, carbon atoms exist in various compounds as they move through a multitude of pathways within Earth's system. That's why NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission—schedule.....»»
Australia"s 116 new coal, oil and gas projects equate to 215 new coal power stations, says researcher
Australia has 116 new coal, oil and gas projects in the pipeline. If they all proceed as planned, an extra 1.4 billion tons of greenhouse gases would be released into the atmosphere annually by 2030......»»
Production yield matters for GaN applications and penetration
The application benefits are getting clear for third-generation compound semiconductor GaN (gallium nitride) as it is increasingly adopted for charging piles, in-vehicle DC-DC power conversion, and on-board chargers (OBC), with the prospect of penetr.....»»
GaN to dominate on-board chargers in the future, says GaN Systems
Gallium nitride (GaN) has been rapidly adopted in mass-market small-voltage chargers and is now making inroads into automotive on-board chargers (OBC), according to Andy Chuang, VP of business development at GaN Systems......»»
China to boost domestic demand to accelerate homegrown GaN industry development
China will increase domestic demand in order to speed up the development of the country's homegrown GaN (gallium nitride) industry, according to industry sources in China......»»
A better understanding of gas exchange between the atmosphere and ocean can improve global climate models
The injection of bubbles from waves breaking in turbulent and cold high-latitude regions of the high seas is an underappreciated way in which atmospheric gases are transported into the interior ocean. An improved mechanistic understanding of gas exch.....»»
Tracing 13 billion years of history by the light of ancient quasars
Astrophysicists in Australia have shed new light on the state of the universe 13 billion years ago by measuring the density of carbon in the gases surrounding ancient galaxies......»»
Trapping and killing superbugs with novel peptide "nanonets"
National University of Singapore (NUS) pharmaceutical scientists have developed synthetic peptide nanonets for treating infections by bacteria strains resistant to last-resort antibiotics......»»
Tesla"s SiC goal fuels discussions of GaN takeover and IGBT revival
With Tesla's recent announcement to cut the use of silicon carbide (SiC) by 75%, some see it as an opportunity for gallium nitride (GaN) to boost its presence in vehicle power electronics. To date, the yield of crystal growth has been a major challen.....»»
Additive reduces methane during long-term storage of dairy cattle and fattening pig slurry
Livestock farming produces large quantities of greenhouse gases, especially methane, which is particularly harmful to the climate. Among other things, it escapes during the storage of animal excrement, the slurry. A study by the University of Bonn no.....»»
Testing the universality of the Feynman-Tan relation in interacting Bose gases using high-order Bragg spectra
The Feynman-Tan relation, obtained by combining Feynman energy relation with Tan's two-body contact, explained excitation spectra of strongly interacting quantum gases of 39K atoms. However, whether Feynman-Tan relation is universal for other atomic.....»»
