Researchers develop a composite film that can be used in nanogenerators to generate electricity from mechanical motion

Researchers have succeeded in storing electricity with the voltage generated from ferromagnetic resonance (FMR) using a nanometer-thin magnetic film. Exploring the storage characteristics of the commonly used iron-cobalt and iron-nickel alloy thin films, they found that by controlling the thermal conditions of the thin film to be within FMR excitation range, energy can be stored by all the electromagnetic waves that surround us – including Wi-Fi.

Scientists develop high performing electrocatalyst to synthesize ammonia in an effort to replace conventional eco-unfriendly methods

Lithium ion batteries use liquid electrolytes that have several drawbacks, which can be overcome by all-solid-state lithium secondary batteries (ASSBs). However, it is important to find efficient electrode materials for ASSBs. A research team from Japan has recently developed a novel electrode material for ASSBs by combining lithium sulfate and lithium ruthenate, which results in improved performance. The scientists hope that their novel approach will guide future research and the eventual commercialization of such high-capacity batteries.

A research team, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has unveiled a new eco-friendly and low-cost method to synthesize indolopyran, one type of nitrogen ring compound, contained in about 60% of drugs that are recently approved by FDA.

Scientists create a 3D digital “twin” of an all-solid-state battery to visualize its interfacial microstructures in detail

The trick to extremely thin supercapacitors with improved performance is spraying graphene ink at an angle.

Researchers have found electrons that behave as if they have no mass, called Dirac electrons, in a compound used in rewritable discs, such as CDs and DVDs. The discovery of “massless” electrons in this phase-change material could lead to faster electronic devices.

Most common thin-film solar panels consist of expensive rare-earth elements like indium and gallium, or highly toxic metals like cadmium. Environment-friendly solar panels consisting of the abundant materials Cu, Zn, Sn offer attractive alternatives, but are hindered by their low practical efficiency compared to their theoretical potential. Researchers from DGIST have now discovered a way to overcome these hurdles.

A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has introduced a new composite catalyst that could efficiently enhance the charg-discharge performances when applied to metal-air batteries (MABs),

DGIST Division of Energy Technology achieves the highest photoelectric conversion efficiency in the world. Huge expectations toward the commercialization of flexible solar cell that is applicable in various fields.
