Wrapping of nanosize copper cubes can help convert carbon dioxide into other chemicals

26-Sep-2022

Researchers found a new way to reduce carbon dioxide (CO2) emissions by wrapping copper nanocubes with an organic layer, solving instability and selectivity problems with copper nanocubes in catalysis, and improving how this electrocatalyst converts CO2 into organic molecules. As the need to ...

World’s first LED lights developed from rice husks

19-Apr-2022

Milling rice to separate the grain from the husks produces about 100 million tons of rice husk waste globally each year. Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the first silicon quantum dot (QD) LED light. Their ...

Answering a century-old question on the origins of life

A team of Japanese scientists found the missing link between chemistry and biology in the origins of life

04-Oct-2021

The missing link isn’t a not-yet-discovered fossil, after all. It’s a tiny, self-replicating globule called a coacervate droplet, developed by two researchers in Japan to represent the evolution of chemistry into biology. “Chemical evolution was first proposed in the 1920s as the idea that life ...

A clue to generate electric current without energy consumption at room temperature

05-Jan-2016

A group of researchers in Japan and China identified the requirements for the development of new types of extremely low power consumption electric devices by studying Cr-doped (Sb, Bi)2Te3 thin films. At extremely low temperatures, an electric current flows around the edge of the film without ...

The Trap Snaps Shut

Researchers isolate the substance that causes Venus flytraps to close

11-Nov-2010

The Venus flytrap is a carnivorous plant luring insect prey with drops of liquid. The trap snaps shut like a steel jaw when an insect touches one of the very fine hairs within. The prey is caught – digestion begins. Minoru Ueda and a research team from the Universities of Tohoku, Hirosaki, and ...
