Effects of ultrasound irradiation on Au nanoparticles deposition on carbon-coated LiNi0.5Mn1.5O4 and its performance as a cathode material for Li ion batteries

Autor: Yasuyuki Tanaka, Hirokazu Okawa, Takahiro Kato, Katsuyasu Sugawara

Publikováno v: Ultrasonics Sonochemistry, Vol 82, Iss , Pp 105879- (2022)

LiNi0.5Mn1.5O4 (LMNO) has attracted considerable attention as a Li-ion battery cathode material, owing to its high discharge voltage of 4.7 V (vs. Li/Li+) and high energy density. However, the electronic conductivity of LMNO is low, resulting in a lo

Desorption of Carbon Dioxide from Monoethanolamine Solution Using Ultrasound and Calcium Chloride

Autor: Tatsuo FUJIWARA, Hirokazu OKAWA, Takahiro KATO, Katsuyasu SUGAWARA

Publikováno v: Journal of MMIJ, Vol 135, Iss 1, Pp 1-7 (2019)

This study investigated an effective method to desorb CO2 from low-concentration (0.2 mol/L) monoethanolamine (MEA) solutions using calcium chloride (CaCl2) and ultrasound irradiation at 25 ºC. The pH value of the solution had a large influence on t

Synthesis of BaTiO3 nanoparticles from TiO2-coated BaCO3 particles derived using a wet-chemical method

Autor: Yuuki Mochizuki, Naoto Tsubouchi, Katsuyasu Sugawara

Publikováno v: Journal of Asian Ceramic Societies, Vol 2, Iss 1, Pp 68-76 (2014)

BaCO3 particles coated with amorphous TiO2 precursor are prepared by a wet chemical method to produce BaTiO3 nanoparticles at low temperatures. Subsequently, we investigate the formation behavior of BaTiO3 particles and the particle growth behavior w
