Abstract In this study, Palm kernel shell (PKS) is utilized as a raw material to produce activated biochar as adsorbent for dye removal from wastewater, specifically methylene blue (MB) dye, by utilizing a simplified and cost-effective approach. Production of activated biochar was carried out using both a furnace and a domestic microwave oven without an inert atmosphere. Three samples of palm kernel shell (PKS) based activated biochar labeled as samples A, B and C were carbonized inside the furnace at 800°C for 1 h and then activated using the microwave-heating technique with varying heating times (0,… More >

Abstract Cu₂ZnSnS₄ nanocrystals (CZTS NCs), MoS₂ nanosheet (NS) and MoS₂-CZTS nanocomposite (NC) have been synthesized using solvothermal route. Structural characterization of samples have been done by XRD, Raman spectroscopy, HR-TEM. Samples have optically characterized by UV-Vis absorption, photoluminescence (PL) and time co-related single photon counting (TCSPC) study. The XRD, HR-TEM and Raman spectroscopy established tetragonal kesterite phase for both CZTS NCs and MoS2-CZTS NC. Enhancement of efficiency of CZTS NCs to degrade methylene blue (MB) dye, illuminated by visible light, have been observed by loading 1 wt.% MoS₂ NS and found to be ~100% in only 15 minutes. More >

Abstract This study aims to synthesize, characterize, and evaluate the photocatalytic efficiency of carboxymethyl cellulose (CMC) wrapped ZnONPs for the degradation of methylene blue (MB) dye under sunlight and also focuses on the effect of varying calcination temperatures on crystallite size of the synthesized ZnONPs@CMC. It focuses on developing biopolymer (CMC) wrapped ZnO nanoparticles (ZnONPs@CMC) at different calcination temperatures. ZnONPs@CMC are synthesized using zinc acetate dihydrate as a precursor under alkaline conditions, followed by adding capping agent CMC at various calcination temperatures ranging from 250°C to 650°C. The nanomaterials are characterized by UV-Vis, FTIR, and powder… More >

Abstract Background and objectives: Hydrocele caused by the division of lymphatic vessels during varicocelectomy is a common complication. Preservation of these lymphatics is the aim of many studies. We evaluated patient outcomes after laparoscopic varicocelectomy that involved intratunical methylene blue dye injection just prior to the procedure.
Materials and methods: This prospective study included all adult patients (over age 14 years) with clinically palpable varicocele who presented to our clinic between December 2005 and July 2007. Prior to laparoscopic surgery, methylene blue dye was injected in the intratunical space between the tunica albuginea and the tunica vaginalis. Laparoscopic intraperitoneal… More >
