Polypropylene (PP) is everywhere, being one of the most widely used plastics in human life. A versatile material, its naturally inert surface can be modified for specific applications. Researchers at Osaka University have now developed a convenient light-driven process for oxidizing PP without ...
Chemists discover way to simplify synthesis of valuable precursor for drugs, other compounds
Rice University scientists have given organic chemists a boost with their latest discovery of a one-step method to add nitrogen to compounds for drugs, pesticides, fertilizers and other products. Rice synthetic organic chemist László Kürti said the method is a major step forward as it quickens ...
Researchers succeed in gaining access to an important chemical compound
Since the discovery of the first homoleptic metal carbonyl complex Ni(CO)4 more than 130 years ago, scientists try to obtain further such compounds formed from a carbon monoxide molecule and a metal that are important for basic research as well as applications. The last new compound of this type ...
How crystalline structure can affect the performance of MnO2 catalysts
Scientists at Tokyo Institute of Technology (Tokyo Tech) have developed and analyzed a novel catalyst for the oxidation of 5-hydroxymethyl furfural, which is crucial for generating new raw materials that replace the classic non-renewable ones used for making many plastics. It should be no ...
Ceramic matrix composites exhibit electrical conductivity and photocatalytic activity
Researchers at Osaka University produced composites consisting of alumina (AI2O3) ceramics and titanium (Ti), namely AI2O3/Ti composites. They designed a percolation structure for forming a continuous conduction pathway by dispersing fine-sized Ti particles into an AI2O3 matrix, optimizing the ...
Scientists from the Nagoya Institute of Technology (NITech) in Japan have developed a sustainable method to neutralize carbon monoxide, the odorless poison produced by cars and home boilers. Traditionally, carbon monoxide needs a noble metal - a rare and expensive ingredient - to convert into ...
Platinum clusters consisting 19 atoms perform 50 times higher catalytic activity
Scientists at Tokyo Institute of Technology produced subnano-sized metallic particles that are very effective as catalysts for the oxidation of hydrocarbons. These catalysts can be as much as 50 times more effective than well-known Au-Pd bimetallic nanocatalysts.The oxidation of aromatic ...
In chemistry, a reaction is spontaneous when it does not need the addition of an external energy input. How much energy is released in a reaction is dictated by the laws of thermodynamics. In the case of the spontaneous reactions that occur in the human body this is often not enough to power ...
Barium ruthenate promises easy handling and high yields
Researchers at Tokyo Institute of Technology have developed a ruthenium-based perovskite catalyst that shows strong activity even at low temperatures (down to 313 K). The reusable catalyst does not require additives, meaning that it can prevent the formation of toxic by-products. The oxidation of ...
Breaking carbon-hydrogen bonds is notoriously difficult in lab chemistry, yet nature does it effortlessly. Now, scientists have used E.coli bacteria to oxidize the C-H bonds in benzene to generate phenol, with a genetically inserted enzyme (cytochrome P450BM3), that originally evolved to target ...
