This study investigates nutritional value, amino acid profile, and total anthocyanin in pigmented rice as an antioxidant anti-diabetic agent. Six varieties were extracted using 0.1% HCl methanol, namely four red rice, one black white rice. Rice extract was used for proximate analysis profiling. Total measured identified by ultraviolet-visible (UV-Vis) spectrophotometer thin-layer chromatography...

Layered double hydroxides (LDHs) are an ultraviolet-light (UV) resistant material. In this study, LDHs were used to modify bitumen. The optical and UV aging properties of LDHs modified bitumen were investigated. Firstly, the thin films of bitumen, with and without LDHs, were prepared. By using the UV-Vis spectrophotometer, absorbance, reflectance, and transmittance of bituminous thin film were ...

Low-dimensional semiconductor nanostructures are of great interest in high performance electronic and photonic devices. ZnO is considered to be a multifunctional material due to its unique properties with potential in various applications. In this work, 3-nm ZnO nanoislands are deposited by Atomic Layer Deposition (ALD) and the electronic properties are characterized by UV-Vis-NIR Spectrophotom...

A recently commercialized sensor, the In Situ Ultraviolet Spectrophotometer (ISUS), can determine seawater nitrate concentrations rapidly. Procedures for incorporating ISUS data within routine conductivity, temperature, and depth (CTD) profiling studies have not been described. Using a CTD system with an ISUS, vertical hydrographic profiles with nutrient concentrations were determined at 42 sit...
