2008715 Our results also reveal that, for fused silica with Ca impurity, the exciton effect plays an important role for the optical absorptions near 355 nm, while it is not significant for K. Our work helps to explore laser damage mechanism and improve manufacture and post-processing techniques of fused silica.
Effect of silica fume and fly ash as cementitious material
202184 The production of cement releases an enormous amount of CO2 into the environment. Besides, industrial wastes like silica fume and fly ash need effective utilization to reduce their impacts on the environment. This research aims to explore the influence of silica fume (SF) and fly ash (FA) individually and combine them as binary cementitious
Silicon as a natural plant guard against insect pests
202211 A rapid and instar-wise effect was reported by reducing feeding and growth rates of the larva. These effects on larval growth and feeding efficiency are nonreversible but continued to act even after the larvae moved to different diets The increased exposure of S. exempta to silica impacted more adverse effects on the growth and development [33].
