The secret of catalysts that increase fuel cell efficiency

Research team reveals the phase transition and metal ex-solution phenomena to increase the catalytic activity


Fuel cells, which are attracting attention as an eco-friendly energy source, obtain electricity and heat simultaneously through the reverse reaction of water electrolysis. Therefore, the catalyst that enhances the reaction efficiency is directly connected to the performance of the fuel cell. To ...

Charging electric cars up to 90% in 6 minutes

Research team uncovers a new Li-ion battery electrode material that can achieve high-energy density and high power capability per volume without reducing particle size


With Telsa in the lead, the electric vehicle market is growing around the world. Unlike conventional cars that use internal combustion engines, electric cars are solely powered by lithium ion batteries, so the battery performance defines the car's overall performance. However, slow charging times ...

Smart AI makes all kinds of shapes on its own

Artificial neural network system recommends plastic molding process conditions


Plastic is light, cheap, and can be made into any shape if heated, making it a "gift from the 20th-century god." The key is to maintain its uniform quality but its sensitivity to process conditions makes processing autonomy difficult. It also takes long to change the process once it is set and ...

Beetles spark development of color-changing nanoparticles for commercial use


Inspired by the varying colors that gleam off of beetle shells, scientists have developed color-shifting nanoparticles that can change hue even after being embedded into a material. A report appeared on the new, inexpensive technique, which could lead to the production of easier-to-read sensors ...

Black phosphorus surges ahead of graphene


A Korean team of scientists tune Black Phosphorous' band gap to form a superior conductor, allowing for the application to be mass produced for electronic and optoelectronics devices The research team operating out of Pohang University of Science and Technology (POSTECH), affiliated with the ...


A cool way to form 2-D conducting polymers using ice


A piece of deep frozen ice and electronic gadgets may seem to have little connection (except that they are both 'cool' to have on you), but ice could now play a role in opening a new era in the electronic industry where conducting polymers, simply put plastics with electrical properties, are in ...


Titania photocatalyst produces hydrogen and generates photocurrents under visible light


Combining a cheap polymer resin with titania produces a photocatalyst that can produce hydrogen and generate photocurrents under visible light, say scientists in the Republic of Korea. Titania is commonly used as a base material for solar energy conversion. But it has a wide band gap so doesn’t ...
