Successfully innovating optoelectronic semiconductor devices depends a lot on moving charges and excitons—electron-hole pairs—in specified directions for the purpose of creating fuels or electricity.

In photosynthesis, pigment molecules absorb and transfer solar energy to a reaction center, where the energy is converted and used...

Researchers developed a novel electrode that effectively suppresses the harmful self-discharge phenomenon in flowless zinc-bromine batteries. The flowless zinc-bromine battery (FLZBB) is a promising alternative to flammable lithium-ion batteries due to its use of non-flammable electrolytes...

A research team led by Professor Kyu-Young Park from the Graduate Institute of Ferrous & Eco Materials Technology and the Department of Materials Science and Engineering and Kyoung Eun Lee, a PhD candidate, and alumna Yura Kim from the Graduate Institute of Ferrous & Eco Materials Technology at Pohang University of Science and Technology (POSTECH), in collaboration with the POSCO Holdings N.EX.T Hub, has recently demonstrated a single-crystal synthesis technology that significantly extends the lifespan of cathode materials for electric vehicles. This research was published in the online edition of ACS Materials & Interfaces, an international journal in the materials science field.

Lithium (Li) secondary batteries, commonly used in electric vehicles, store energy by converting elect...

Researchers from Germany, Italy, and the UK have achieved a major advance in the development of materials suitable for on-chip energy harvesting. By composing an alloy made of silicon, germanium and tin, they were able to create a thermoelectric material, promising to transform the waste heat of computer processors back into electricity.

With all elements coming from the 4th main group of the periodic table, these new semiconductor alloy can be easily integrated into the CMOS process of chip production...
