Baek, Jiyoo; Ramasamy, Mohankandhasamy; Willis, Natasha Carly; Kim, Dae Sung; Anderson, William A.; Tam, Kam C. (Elsevier, 2021)Vitamin C (VC), widely used in food, pharmaceutical and cosmetic products, is susceptible to degradation, and new formulations are necessary to maintain its stability. To address this challenge, VC encapsulation was achieved ... -
Experimental and kinetic study of vacuum residue cracking over zirconium based catalysts
Abd Al-Karim, Aya; Shakor, Zaidoon M.; Al-Sheikh, Farooq; Anderson, William A. (Springer, 2022-04-01)In this study, thermal cracking and catalytic cracking over zirconium-based catalysts of the vacuum residue were achieved in the presence of supercritical steam at 400-450 degrees C, 20 bar, and 2-4 h. Two different catalysts ... -
Formation of Secondary Organic Aerosols by Germicidal Ultraviolet Light
Choi, Eureka; Tan, Zhongchao; Anderson, William A. (Multidisciplinary Digital Publishing Institute, 2019-01-31)Ultraviolet (UV) light with a wavelength of 254 nm is known to be germicidal, and thus has been increasingly employed as a method of disinfection for indoor environments. Solar UV wavelengths (300 to 400 nm) are known to ... -
Metal organic framework (MOF) porous octahedral nanocrystals of Cu-BTC: Synthesis, properties and enhanced adsorption properties
