Abstract The current world energy crisis and increase in global temperature has further necessitated the need to conduct more research on solar cells. Dye sensitized cells (DSSCs) remain one of cheapest cell technologies, but it inherent challenges. Titanium dioxide (TiO 2 ) remains suitable electrode materials, requires modification withstand technology problems. In this paper, silica was prod...

Nanoparticles of titanium diboride (TiB2) coated with a conductive polymer and subjected to an oxidizing agent was carried out in this research. TiB2 nanoparticles polypyrrole (PPy) were studied using XRD TEM techniques. Nitrogen adsorption desorption properties are covered modified understand better the surface zone, structural features, pore geometries nanoparticles. The water-based hazardous...

The technology of 4DP utilizes shape memory materials (SMMs). Among the SMMs, SMP is material that has potential and ideal for this technology. However, due to their restrictions, fillers are incorporated produce a novel polymer composite (SMPC). objective present work was investigate how modification PLA via incorporation boehmite alumina thermochromic dye, use 3DP on polyester fabric make sma...

The interest in dye-sensitized solar cells has increased due to reduced energy sources and higher energy production costs. For the most part, titania (TiO2) has been the material of choice for dye-sensitized solar cells and so far have shown to exhibit the highest overall light conversion efficiency ∼ 11 %. However, zinc oxide (ZnO) has recently been explored as an alternative material in dye-s...

low-cost grapefruit peel (agricultural waste) was used for removal of reactive blue19 dye fromaqueous solutions. the process was studied as a function of contact time, initial dye concentration andph. adsorption process was attained to the equilibrium within 45 min for initial dye concentrations of 50,75, and 100 mg l-1. an acidic medium was the optimum condition for adsorption of dye at roomte...

Abstract Modification of the adsorbent surfaces has been considered a fascinating strategy that enhances biomass-based adsorption properties for efficient removal organic pollutants. This is based on attempt to replace cost-ineffectiveness commercial activated carbon. The present study discusses different modification strategies and review modified biomass materials sorption contaminants. Unlik...
