Catalytic synthesis of phenols with nitrous oxide
The emission of greenhouse gases threatens the global environment, and scientists around the world are increasingly committed to addressing this issue. While many research groups focus on carbon dioxide (CO2) or methane (CH4) revalorization strategie.....»»
Scientists identify electronic and structural dynamics of catalytic centers in single-Fe-atom materials
Single-atom catalyst (SAC) is a conceptual bridge between homo- and heterogeneous catalysis. It offers new opportunities for capturing the reaction intermediates by identifying the active sites, and even monitoring the dynamic behaviors of both the g.....»»
Researchers discover C-H bond activation reactions at low temperature by photo-induced means
The C-H bond is very important in organic chemistry. Chemical reactions related to the breaking and further synthesis of the C-H bond require high activation energy and poor selectivity. Therefore, it's important to understand the reaction mechanism.....»»
Controlling the magnetic properties of complex oxide systems
The study of complex oxides of iron to create new functional materials is one of the most intensely developing fields of investigation for SUSU scientists. The physical properties of complex iron oxide systems can be varied by changing the chemical c.....»»
Researchers develop layered cobalt oxide with a record-setting thermoelectric figure of merit
Waste heat is a highly promising source of renewable energy; however, the efficiency of using heat to generate energy has historically been much lower than hydroelectric, wind or solar power. While there are a number of materials that can be used for.....»»
Detailed structure of ribosomes in nerve cells revealed
Protein synthesis is a finely tuned process in the cell by macromolecules known as ribosomes. Which regulators are responsible for controlling protein synthesis in the brain, and how do they exert their control on the ribosome? To address this questi.....»»
New method for the development of choline acetyltransferase inhibitors
The enzyme choline acetyltransferase (ChAT) catalyzes the synthesis of the neurotransmitter acetylcholine and could be a target molecule for pharmaceuticals. A Swedish research team has now determined the mechanism by which arylvinylpyridinium (AVP),.....»»
New catalytic approach to accessing key intermediate carbocation
Human civilization in the 21st century is largely sustained by modern chemical technologies. The raw materials used in the manufacturing of a wide range of products, from clothing to plastics and pharmaceuticals, are mainly produced through efficient.....»»
Novel crystalline oxide may solve the problem of overheating in composite materials
Scientists at Tokyo Institute of Technology recently synthesized a novel material that displays unique thermal expansion properties. The method used by the scientists enables the production of a unique crystalline oxide containing zirconium, sulfur,.....»»
New catalytic process turns plastic bags into adhesives
While many cities and eight states have banned single-use plastics, bags and other polyethylene packaging still clog landfills and pollute rivers and oceans......»»
Catalytic activity of individual cobalt oxide nanoparticles determined
Precious metal-free nanoparticles could serve as powerful catalysts in the future, for example for hydrogen production. To optimize them, researchers must be able to analyze the properties of individual particles. A new method for this has been sugge.....»»
How water helps the substrate into the enzyme
Researchers from Bochum and Berkeley have investigated why cages can increase the catalytic activity of enclosed molecules. Using terahertz spectroscopy and complex computer simulations, they showed that water encapsulated in a tiny cage has special.....»»
A genetic control of stem cell differentiation and organ maintenance by induction of fat metabolism
Fat metabolism (lipid metabolism) is the term used to describe the synthesis and degradation of lipids in cells. This is increasingly recognized as an important key process that could also influence the maintenance and differentiation of stem cells......»»
