As the thickness of silicon solar wafer and solar cells becomes thinner, the cells are subjected to high stress due to the thermal coefficient mismatch induced by metallization process. Handling and bowing problems associated with thinner wafers become increasingly important, as these can lead to cells cracking and thus to high yield losses. The goal of this work to provide experimental underst...

The aim of this study was to evaluate the interference of the radiopacifiers bismuth oxide (BO), bismuth carbonate (BC), bismuth subnitrate (BS), and zirconiun oxide (ZO) on the solubility, alkalinity and antimicrobial properties of white Portland cement (WPC). The substances were incorporated to PC, at a ratio of 1:4 (v/v) and subjected to a solubility test. To evaluate the pH, the cements wer...

Zinc and iron nano-oxides (100 ppb) were promoted the hypericin and hyperforin production in Hypericum perforatum cell suspension culture. High performance liquid chromatography method was used for detectection and identification of hypericin and hyperforin in H. perfuratum cell suspension cultures elicited with different concentrations of zinc and iron nano-oxide (0, 50, 100 and 150 ppb) after...

iron deficiency in soil reduces the quality of durum wheat leading to fe deficiency in human. thus, this experiment investigated the effects of foliar application of nano-iron oxide (2 and 4 g l-1), iron chelate (edta), (4 and 8 g l-1), iron sulfate (4 and 8 g l-1), and the control on grain yield and quality, yield components, chlorophyll and carotenoids contents, peroxidase (pox), catalase (ca...

Computational studies have attracted the attention of researchers to understand the structural behavior of the molecules. These methods grade complex systems for novel properties with new predictions in areas of physics, chemistry and biology useful for conduct of experimental studies. Nanoparticles in present day technologies have become integral part in diverse areas of science mostly with me...
