Abstract The success of colloidal semiconductor nanocrystals (NCs) in science and optoelectronics is inextricable from their surfaces. functionalization lead halide perovskite NCs 1–5 poses a formidable challenge because structural lability, unlike the well-established covalent ligand capping conventional 6,7 . We posited that vast facile molecular engineering phospholipids as zwitterionic surfactants can deliver highly customized surface chemistries for metal NCs. Molecular dynamics...
Biphasic bioceramic nanopowders of hydroxyapatite (HA) and β ‐tricalcium phosphate (TCP) were prepared from shells the sea snail Cerithium vulgatum (Bruguière, 1792) using a novel chemical method. Calcination powders produced was carried out at varying temperatures, specifically 400°C 800°C, in air for 4 hours. When compared to conventional hydrothermal transformation method, this method is very simple, economic, due fact that it needs inexpensive safe equipment, because aragonite calcite...
In bone tissue engineering, scaffold attributes such as pore dimensions and mechanical strength are crucial. This study synthesized polycaprolactone dimethacrylate (PCLDMA) from (PCL), incorporating epichlorohydrin (Epi-PCL) methacryloyl chloride (Meth-Cl). PCLDMA was blended with polylactic acid (p-PLA) to 3D-print scaffolds using stereolithography (SLA). Analytical techniques included nuclear magnetic resonance (NMR), Fourier-transform infrared spectroscopy (FTIR), scanning electron...

The demand for tissue scaffolds to support the repair, regeneration, and restoration of damaged tissues is rapidly growing. Scaffolds fabricated using electrospinning technique are particularly significant in engineering due their ability provide micro- nano-scale porosity a large surface area. This study focuses on developing with enhanced cell adhesion, biodegradability, tensile strength by employing aqueous solutions polyvinyl alcohol (PVA), biocompatible biodegradable synthetic polymer;...
We evaluated the Bovine hydroxyapatite (BHA) structure. BHA powder was admixed with 5 and 10 wt% natural pumice (NP). Compression strength, Vickers micro hardness, Fourier transform infrared spectroscopy, scanning electron microscopy (SEM) X-ray diffraction studies were performed on final NP-BHA composite products. The cells proliferation investigated by MTT assay SEM. Furthermore, antimicrobial activity of samples interrogated. Variances in sintering temperature (for NP composites) between...
