This review discusses the impact of green and environmentally safe chemistry on the field of nanotechnology-driven drug delivery in a new field termed "green nanomedicine". Studies have shown that among many examples of green nanotechnology-driven drug delivery systems, those receiving the greatest amount of attention include nanometal particles, polymers, and biological materials. Furthermore,...

Catalytic hydrolysis technology of carbonyl sulfide (COS) at low temperature was reviewed, including the development of catalysts, reaction kinetics, and reaction mechanism of COS hydrolysis. It was indicated that the catalysts are mainly involved metal oxide and activated carbon. The active ingredients which can load on COS hydrolysis catalyst include alkali metal, alkaline earth metal, transi...

In this study, commercial zinc oxide nanoparticles were used. Various techniques such as AFM, XRD, and FTIR employed to characterize their surface studies. From the XRD analysis, each reflection peak with relative intensity of different planes determined presence ZnO spectrum revealed that particle size was about (27.43 nm), which is in good agreement those estimated from AFM analysis. It showe...

objective: pmbn, poly [2-methacryloyloxyethyl phosphoryl choline (mpc)-co-n- buthyl methacrylate (bma)-co-p-nitrophenyl- oxycrabonyl poly (ethylene glycol-methacrylate (meonp)], as a biocompatible ter-polymer is a unique polymer with wide range of application from drug delivery systems to scaffolds and biomedical devices. in this research, monomer of p- nitrophenyl- oxycarbonyl poly (ethylene g...

In this study, effects of TiO$_{2}$ and ZnO nanometal oxides on cellulose pyrolysis have been investigated. Both catalysts synthesized via hydrothermal method characterized by using different techniques. Catalytic catalyst-free experiments were carried out so as to identify the catalytic abilities nanoparticles. Catalyst-free at 500, 600, 700 °C in order determine optimal condition for it was f...

Abstract This paper aims to study a passivation technology and process of iron nanopowder, provides basic theory experimental data for promoting the practical application nanopowder as high-efficiency catalyst in production ammonia. There are two specific objectives. The first one is provide nanometal powder device prevent nano metal from being oxidized deactivated. second method using passivat...

This paper provides experimental data on the effective use of a new lubricating composition, which includes industrial oil any brand with addition nanometal component friction pair, has lower hardness. It is shown that this composition significantly reduces wear resistance rails and wheels rolling stock during operation, prevents electrochemical corrosion pair wheel–rail and, most importantly, ...
