Green catalysts with Earth-abundant metals accelerate production of bio-based plastic

How crystalline structure can affect the performance of MnO2 catalysts

10-Jan-2019

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 ...

Multifunctional dream ceramic matrix composites are born!

Ceramic matrix composites exhibit electrical conductivity and photocatalytic activity

07-Dec-2018

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 ...

Metallic nanoparticles light up another path towards eco-friendly catalysts

Platinum clusters consisting 19 atoms perform 50 times higher catalytic activity

19-Nov-2018

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 ...

A boost for biofuel cells

03-Sep-2018

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 ...

Oxidation of sulfides with perovskite catalyst

Barium ruthenate promises easy handling and high yields

17-Jul-2018

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 ...

'Tricking' bacteria into hydroxylating benzene

15-Jun-2018

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 ...

Double graphene sandwich provides protection against corrosion

07-Jun-2018

”Normally it’s not a huge success that not a damn thing has happened after 120 days.” These words belong to Professor Peter Bøggild after a four-month period where a novel type of anticorrosion coating was tested. The nanomaterial graphene plays a crucial role in this new type of coating. ...

Mat baits, hooks and destroys pollutants in water

23-Mar-2018

A polymer mat developed at Rice University has the ability to fish biologically harmful contaminants from water through a strategy known as "bait, hook and destroy." Tests with wastewater showed the mat can efficiently remove targeted pollutants, in this case a pair of biologically harmful ...

What happens when electrons get wet?

31-Jan-2018

There's a particular set of chemical reactions that governs many of the processes around us--everything from bridges corroding in water to your breakfast breaking down in your gut. One crucial part of that reaction involves electrons striking water, and despite how commonplace this reaction is, ...
