Packaging containing nanoparticles (NPs) can increase the shelf life of products, but presence NPs may hazards human life. In this regard, there are reports regarding side effect and cytotoxicity nanoparticles. The main aim research was to study migration silver copper from packaging food matrix as well assessment techniques. diffusion be analyzed by analytical techniques including atomic absor...

The advent of rare earth elements (REEs) with optoelectronic properties has shifted the technology paradigm from digital to a smart and hybrid world. Their substantial uses also resulted in large piling up e-waste. Therefore, e-waste is now lucrative recycling target for recovery such critical raw materials. often challenged by dilute metal concentration, complex composition, difficult chemical...

Decontamination treatments of surfaces are performed on bacterial spores, albumin and brain homogenate used as models of biological contaminations in a low-pressure, inductively coupled plasma reactor operated with water-vapour-based gas mixtures. It is shown that removal of contamination can be achieved using pure H2O or Ar/H2O mixtures at low temperatures with removal rates comparable to oxyg...

The inductively coupled plasma etching characteristics of Co2MnSi thin films patterned using a TiN hard mask were investigated by the addition of CH3OH to Ar gas. As the CH3OH concentration increased, the etch rates of Co2MnSi magnetic thin films and TiN hard mask decreased, but the etch profile improved. The effects of rf power, dc-bias voltage and gas pressure on the etch rate and etch profil...
