Controlled burns help prevent wildfires, but climate change is limiting their use
Prescribed fires, sometimes called controlled burns, are one of the most common tools for preventing catastrophic wildfires in the Western United States. Lit by highly trained firefighters, they help clear away excess dry plant matter that might othe.....»»
Insights into ethylene copolymerization with linear and end-cyclized olefins using a metallocene catalyst
A research team led by Changjiang Wu at SINOPEC (Beijing) Research Institute of Chemical Industry Co., Ltd. in China has made important progress in understanding the polymerization behavior and thermal properties of copolymers formed through ethylene.....»»
Auto industry faced with more uncertainty if government shuts down
Congress needs to pass a spending bill before Sunday to avoid a shutdown. However, lawmakers remain at odds over the funding, with some House Republicans pushing for deep spending cuts that are unlikely to survive in the Democratic-controlled Senate......»»
A breakthrough discovery could accelerate the arrival of controlled fusion energy on Earth
Researchers led by Chang Liu of PPPL have unveiled a promising approach to mitigating damaging runaway electrons created by disruptions in tokamak fusion devices. Key to the approach was harnessing a unique type of plasma wave that bears the name of.....»»
BSI-AST chip: A powerful tool to accelerate antimicrobial susceptibility testing for bloodstream infections
The presence of viable bacteria in the blood (bacteremia) when not controlled properly can lead to bloodstream infection (BSI) and sepsis, a syndromic inflammatory response......»»
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.....»»
Water films: The silent architects of chemical transformations
Water films are virtually present on all minerals exposed to air moisture, from dry soils to atmospheric dust. The number of water layers that minerals can store is directly controlled by atmospheric humidity......»»
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 resolves molecular switching behavior of azonium compounds for light-controlled drugs
Molecules that change shape under the influence of light can be used as switches in biomedical applications, for instance to inhibit an enzyme. An international team of researchers, including chemists at the Universities of Amsterdam and Groningen, h.....»»
How do zeolite-encapsulated metal catalysts act on hydrogen-related catalytic reactions?
Zeolites encapsulated metal and metal oxide species (regarded as metal@zeolite) are an important type of heterogeneous catalyst. They give performances that steadily outperform the traditional supported catalysts in many important reactions and have.....»»
Innovative catalyst advances acidic water splitting technology
Researchers from the Shanghai Institute of Ceramics of the Chinese Academy of Sciences, together with collaborators, have made a significant breakthrough in electrocatalytic water splitting, a key technology for converting intermittent solar and wind.....»»
Smoke shrouds Sydney landmarks as risky bushfire season looms
A smoky haze blanketed Australia's scenic Sydney Harbour on Wednesday, as a ring of controlled blazes burned on the city's fringes in preparation for the looming bushfire season......»»
Researchers develop novel catalyst for carbon dioxide hydrogenation to formate
Hydrogenation of carbon dioxide (CO2) to formate is an attractive approach for the utilization of this greenhouse gas. However, non-precious metal-based catalysts for CO2 hydrogenation to formate suffer from either low activity or low stability. It i.....»»
Investigating ancient irrigation tunnels with a remote controlled car
In ancient times, the desert in the Udhruh region in Jordan was transformed into a green oasis. An intricate network of underground water channels was part of an ancient system of water management, storing water and preventing loss through evaporatio.....»»
Telepresence classroom robots trialed for absent students
A school in Japan will deploy telepresence robots that can be controlled by absent students in the hope that it may encourage them to return to the classroom......»»
Using lignin and a catalyst to create an alternative to bisphenol A (BPA)
A team of microbiologists and chemists at the Center for Sustainable Catalysis and Engineering, working with colleagues from Vrije Universiteit Brussel, the Flemish Institute for Technological Research and Rheology and Technology (SMaRT), KU Leuven,.....»»
New catalyst decreases the energy required to split hydrogen gas from water
Hydrogen gas is a clean, renewable alternative to fossil fuels, but current industrial production methods used to produce hydrogen release carbon into the atmosphere and pollute the environment......»»
Opinion: White men have controlled women"s reproductive rights throughout US history and post-Dobbs era is no different
