bioactive materials including glass and glass-ceramics are nowadays used as medical implants for orthopedic applications. in this study several samples of glass-ceramics have been prepared using both heat treatment and sol-gel processes. the structure and bioactivity of these samples based on their interaction with simulated body fluid (sbf) have been determined. in-vitor, using the raman spect...

Heavy metal pollution is a serious environmental problem that can be remediated by various adsorbents. So, new hydroxyapatite / graphene oxide nanocomposite (HAp/GO) material was synthesized from waste eggshell as green and eco-friendly adsorbent for the effective removal of heavy metals (e.g., Cd, Pb, Cr, Ni, Co) wastewaters. Nano-structured HAp calcination followed hydrothermal treatment in p...

Microplastics (MPs) and nanoplastics (NPs) constitute a newly recognized class of contaminants emerging concern in air, soil, water food, causing unavoidable exposure to humans animals. Detection, identification quantification MPs NPs environmental matrices biota is challenging due the analytes' small size, random morphology, polymeric diversity, applied coatings vast surface areas which attrac...

Abstract Several types of (mostly) blue-green glass beads from Iron-Age archaeological sites in Central Italy were studied using a range spectroscopic techniques: portable X-Ray Fluorescence spectrometry, Fibre Optics Reflectance Spectroscopy, Scanning Electron Microscopy coupled with Energy Dispersive X-ray Spectrometry, micro-Raman spectroscopy and Laser Ablation Inductively Coupled Plasma Ma...
