Enzymes Immobilization onto different types of the substrate could be helpful in various applicationsof biomedical devices and biosensors. Enzyme activity and stability could be affected by support andmethod of immobilization. In this study, the silver metal foam was successfully synthesized by thesoft-shell method and then was coated with silica. Then, glucose oxidase (GOx) immobilized on nonc...

With the diversity and multiplicity of materials used in production jewelry throughout history development design successive ages decades, metal still basic raw material for

BACKGROUND Due to pedogeochemical background and anthropogenic sources, heavy metal contamination of soil is a widespread problem in some parts of Zanjan province located in North West Iran. In this study an affected area located near National Iranian Lead and Zinc Company (NILZ) was selected for detailed study. METHODOLOGY Thirty soil samples and eighteen leaf samples were collected and anal...

rapid expansion of the industrial sector adds more effluent into the agricultural land and in the vicinity of industry, which possesses the major threat of land contamination and environmental degradation. the present study was conducted to determine toxic metal concentration in fly ash and metal accumulation potential of the saccharum munja and cynodon dactylon, the two main grass species grow...

Tailoring the polymer-metal interface is crucial for advanced material design. Vacuum deposition methods for metal layer coating are widely used in industry and research. They allow for installing a variety of nanostructures, often making use of the selective interaction of the metal atoms with the underlying polymer thin film. The polymer thin film may eventually be nanostructured, too, in ord...
