Pistachio shell powder supported nano-zerovalent copper (ZVC@PS) material prepared by borohydride reduction was characterized using SEM, FTIR, XRD, TGA/DTA, BET, and XPS. XPS revealed the to consist of a core-shell structure with CuO Cu(0) core particle size 40–100 nm spherical morphology aggregated on PS biomass. ZVC@PS found contain 39% (w/w %) Cu onto pistachio Batch sorption Cr(VI) from aqu...

B2223 High Temperature Superconductor (HTSC) has been prepared as a pellet by solid state reaction. Then, HTSC wires were fabricated from the prepared superconductor using powder in tube (PIT) method utilizing silver as the tube material. Superconductor powder was packed in the pure silver tube of about 4.5 mm diameter, and 50mm long. The prepared wires are of three types; with monofilament MOF...

Core@shell and concentration-gradient particles have attracted much attention as improved cathodes for Li-ion batteries (LIBs). However, most of their preparation routes have employed a precisely-controlled co-precipitation method. Here, we report a facile preparation route of core@shell and concentration-gradient spinel particles by dry powder processing. The core@shell particles composed of t...
