Newly designed ligands for a catalytic reaction to synthesize drugs and useful compounds
Currently, various therapeutic compounds in the market, such as proteins, enzymes, and amino acids, are "chiral compounds"--molecules with two structures that are "mirror" images of each other but cannot be superimposed. Although the two variants of the molecule, also called "enantiomers," are ...
A novel pretreatment strategy resolves a long-standing issue of silicon anode materials
A team of Korean researchers has developed a processing technology for maximizing energy densities of high-capacity batteries. The joint research team, which consists of Dr. Lee, Minah of the Center for Energy Storage Research and Dr. Hong, Jihyun of the Center for Energy Materials Research, both ...
Non-conductive silica could be key to realizing next-generation lithium-sulfur batteries
The tremendous increase in the use of mobile technology, wearable electronics, and a wide range of portable devices in general over the past few decades, has driven scientists worldwide to seek out the next breakthrough in rechargeable batteries. Lithium-sulfur batteries (LSBs)--composed of a ...
Polystyrene waste to break down with enzymes or bacteria?
Resembling giant mealworms, superworms (Zophobas atratus) are beetle larvae that are often sold in pet stores as feed for reptiles, fish and birds. In addition to their relatively large size (about 2 inches long), these worms have another superpower: They can degrade polystyrene plastic. Now, ...
The porous carbon composite is applicable to various fields
South Korea with its high antibiotic use is categorized as a country at high risk of the emergence of multi drug-resistant bacteria, or so-called "super bacteria." According to the Ministry of Environment, antibiotic substances have been detected at livestock wastewater treatment facilities, ...
A Korean research team has succeeded in developing next-generation high-capacity cathode material for lithium-ion batteries. The Korea Institute of Science and Technology (KIST, Acting President Seok-jin Yoon) announced that the joint research team of Dr. Kyung Yoon Chung (head of the Center for ...
Dr. Yoon Hana at Energy Conversion & Storage Materials Laboratory of Korea Institute of Energy Research (KIER, President Kim Jong-nam), Professor Kim Young-Jin (Dept. of Mechanical Engineering, Korea Advanced Institute of Science and Technology) and Professor Kim Seungchul (Dept. of Optics and ...
Metal-Air Batteries (MABs), which use oxygen from ambient air as recourses to store and convert energy, have received considerable attention for their potential use in electric vehicles (EVs) owing to their large storage capacity, lightweight, and affordability. A research team, affiliated with ...
KAIST researchers developed a three-dimensional (3D) hierarchically porous nanostructured catalyst with carbon dioxide (CO2) to carbon monoxide (CO) conversion rate up to 3.96 times higher than that of conventional nanoporous gold catalysts. This new catalyst helps overcome the existing ...
Chlorine (Cl₂) is one of the most widely used industrial chemicals in the world today, with75 million tons produced annually.A team of researchers, affiliated with UNIST has recentlyfound a way to make the manufacture of chlorine more efficient andaffordable. This is expected to be of great ...
