Article Synopsis
- A high-performance gas sensor that operates at room temperature simplifies manufacturing and reduces power consumption by removing the need for a heater.
- The ammonia gas sensor was created using titanium dioxide (TiO) nanosheets decorated with gold (Au) nanoparticles, made through flux growth and chemical exfoliation followed by a hydrothermal method.
- The sensor showed a strong response (~2.8) at room temperature and at a concentration of 20 ppm of ammonia gas, due to the oxygen defects and spillover effects created by the Au nanoparticles on the TiO surface.
Article Synopsis
- - Surface modification of titanium dioxide nanoparticles using a specific polymerizable chelating agent improved their performance in various applications like pigments and cosmetics.
- - The coating process led to a decrease in the nanoparticles' photocatalytic activity, reduced aggregation, and maintained low viscosity even at high solid content.
- - This modification enhanced UV protection and dispersion stability while altering the color of the nanoparticles, making them potentially suitable for cosmetic uses.
Esculetin 6-O-β-D-arabinofuranosyl-(1→6)-β-D-glucopyranoside (EAG) is a coumarin glycoside isolated from the stem bark of . This study scrutinized the anti-proliferative activity of EAG on blood cancer-derived Jurkat leukemic cells. Cell viability assays in leukemic cancer cells determined that EAG possesses potent anti-proliferative effects.
