■ Gwang-seop Eom, a research team at the Gwangju Institute of Science and Technology (GIST) Department of Materials Science and Engineering, announced on the 3rd that it developed a negative electrode that weighs a third and has a larger storage capacity than the negative electrode, a material previously used in lithium-ion batteries. The research team drastically reduced the weight and volume of the porous structure by freely controlling the porosity and pore diameter of the porous structure containing lithium, one of the anode materials. As a result of comparing the energy storage per weight and energy storage per volume of the lithium-ion battery made of this porous structure and the existing lithium-ion battery, the performance reached about 1.5 times. The study was published in the January 18th online edition of the international journal Energy Storage Materials.
■ Jo Jeong-ah announced on the 3rd that a research team made up of 11 undergraduate students and professors at the Daegu Gyeongbuk Institute of Science and Technology (DGIST) proved that exosomes can be efficiently measured using a dynamic optical scattering photometer (DLS). Exosomes are nano-sized particles used in drug delivery systems. The research team revealed that it is sufficiently reliable to measure the size and homogeneity of exosomes with DLS by statistically comparing the size and homogeneity of exosomes after measurement with a transmission electron microscope and DLS. The study was published on January 26, the Internet edition of the international journal’Floss One’.
