Herein, Starch/Zeolitic imidazolate framework (ZIF-67)/Graphene oxide biocomposites (SZ67GO) were synthesized with various starch values (0.5, 1 and 1.5 g denoted as SZ67GO-0.5, SZ67GO-1 and SZ67GO-1.5,

Synthesis and characterization of Bi2O3–B2O3–SiO2–MgO glasses: Structural, optical, and shielding properties Opt. Mater. (IF 3.9) Pub Date : 2024-04-09 Khalid Alsafi, Dalal Abdullah Aloraini, Shams A.M. Issa, Hesham M.H. Zakaly, E.E. Assem, Kh S. Shaaban
The systematic investigation of the impact of BiO on the structural, spectroscopic, and radiation features of 15SiO - 75BO - () MgO - BiO, = () glasses were studied. The increase in glass density as BiO content increase is due to the incorporation of BiO into the glass network. XRD patterns indicate an amorphous, glassy nature of the glasses. The optical absorption spectra suggest that as the content

An insight into the effect of ZnWO4/ZnS nanoparticles on the optical and electrical characteristics of PVA/PVP/CMC blended polymer for optoelectronic and energy storage applications Opt. Mater. (IF 3.9) Pub Date : 2024-04-09 Mohamed Bakr Mohamed, Zein K. Heiba, A.M. El-naggar, A.M. Kamal
The blends of polyvinyl alcohol (PVA), polyvinyl pyrrolidone (PVP) and carboxymethyl cellulose (CMC) composites incorporated with (1-x)ZnWO/xZnS fillers have been formed and characterized. X-ray diffraction (XRD) was used to determine the different phases in the formed fillers. The crystallite sizes of the fillers were determined using Scherrer relation and confirmed by the transmittance electron microscope

Boosting photocatalytic activity via interfacial interaction and BiOCl0.2Br0.8/g-C3N4 Z-scheme heterojunction with nitrogen-oxygen vacancy Opt. Mater. (IF 3.9) Pub Date : 2024-04-09 Peijie Wang, Mingchun Li, Minggao Song, Huifeng Li, Zihan Ping, Guanyu Zhao, Yusheng Wu, Laishi Li
The 3D hierarchical BiOClBr/g-CN Z-scheme heterojunction containing double vacancy under strong interfacial interaction was formed via a hydrothermal method. In this work, the electrostatic field-enhanced interfacial interaction generated by post-hydrolyzed -glutamic acid promoted the generation of nitrogen-oxygen defect and the achievement of a stable 3D porous structure. In particular, the BiOClBr/g-CN
