Article Abstract
This study examines the efficacy of photovoltaic (PV) recycling processes and technologies for the recovery of high-purity silicon powder from waste solar modules. In order to facilitate the simplification of complex processes, such as the conventional nitric acid dissolution, solvent and ultrasonic irradiation, and solvent dissolution, a variety of mechanical separation processes have been established. These processes are designed to enhance the efficiency and effectiveness of the aforementioned processes. And a novel method for separating EVA from recycled Si powder was devised, which studied the WGS process using aqueous solutions of HO, HNO, and NaCl with different specific gravities. The WGS process using NaCl solution demonstrated superior performance, removing over 94% of the EVA, requiring less energy input and producing 73% less CO emissions compared to the thermal process. These technologies facilitate the transition towards a circular economy and bolster the implementation of carbon-neutral initiatives.

Ammonia (NH) has emerged as a promising hydrogen (H) carrier thanks to its high hydrogen content (17.6 wt %) and easy liquification. However, conventional NH cracking requires high temperatures (400-600 °C) and additional gas separation processes, increasing the regeneration cost of high-purity H.

Here, we propose a novel approach using a transmission-type Pancharatnam-Berry (PB) meta-surface to generate nearly perfect focused terahertz vortex beams with opposite incident circular polarization. Our design leverages silicon pillars composed of two-layer structures exhibiting opposite symmetry Fabry-Perot resonances along two orthogonal directions, serving as high performance meta-atoms capable of both generating PB phase and achieving high transmittance.

Bone defects from trauma, infection, and tumour resection are a growing clinical challenge due to global population aging. Current treatments like autologous and allogeneic bone grafting have limitations. This study focused on optimizing ion-doped α-tricalcium phosphate (α-TCP) preparation and developing calcium phosphate cement (CPC) with superior physicochemical and biological properties.

With a focus on extending the horizons of combining electronic waste (e-waste) with different materials for creating efficient, affordable, eco-friendly, and sustainable radiation shielding composites, the present study investigates the radiation shielding performance of different composites made of silicon rubber and e-waste glass. Six samples were prepared by mixing different amounts of powdered cathode ray tube (CRT) glass (0-50%) with silicon rubber (100-50%). The linear attenuation coefficients (LAC's) of the prepared samples were experimentally measured using a high-purity germanium detector and varying energy gamma sources.
