Cellulose nanocrystals (CNCs) are biodegradable nanoparticles with a high aspect ratio and abundant surface hydroxyl groups resulting in negatively charged hydrophilic surfaces that make them an ideal candidate to be incorporated thin-film nanocomposite (TFN) membranes. In this study, we modified the CNCs via acetylation (ACNCs) reduce their hydrophilicity reaction L-cysteine (CysCNCs) impart f...

Abstract Self-assembled nanocomposite thin films couple two materials into a single film, typically, in the form of vertically aligned nanopillars embedded matrix film. High-density vertical heterointerfaces provide great platform for engineering new physical properties and novel multifunctionalities, as well nanoscale device integration. Tremendous research efforts have been devoted to develop...

The Ag-Ge-S system is among the best-performing active materials for a new class of high-performance electronic memory known as programmable metallization cells.[1,2] Memory switching in a programmable metallization cell relies on the electrochemical formation and dissolution of an electronically conducting filament within a solid electrolyte. In the Ag-Ge-S system, this electrochemical process...

Thin-film composite (TFC) membranes show great potential in dye nanofiltration but their performance still required further improvement. In this work, ultra-small EMT zeolite nanocrystals were embedded into the interfacial polymerized polyamide (PA) layer supported on porous nylon via spray dispersion method and used separation. Ultra-small nanosized crystals with plate-like morphology synthesi...

Peroxidase has been immobilized onto the PVA-PANI nanocomposite film deposited onto gold plate via physical adsorption for peroxide detection. PVA-PANI nanocomposite was characterized by scanning electron micrograph (SEM) before and after immobilization. The SEM picture clearly shows the immobilization of peroxidase onto the PVA-PANI. The cyclic voltametric study is also carried out for the as ...

Nanocomposite films of metal nitrides such as TiN/Si3N4, TiN/BN, and CrN/AlN have attracted substantial attention as coating materials for improving hardness and saving rare metals. It is difficult to prepare composite films consisting of nitride and oxide by conventional reactive sputtering methods. Nose et al. developed a differential pumping cosputtering (DPCS) system, which can fabricate di...

A novel nanocomposite polyvinyl alcohol precursor-based material dispersed with the web of carbon microfibers and carbon nanofibers is developed as lithium (Li)-ion electrolyte battery separator. The primary synthesis steps of the separator material consist of esterification of polyvinyl acetate to produce polyvinyl alcohol gel, ball-milling of the surfactant dispersed carbon micro-nanofibers, ...

the effect of evaporation rate on structural, morphological and optical properties of electron beam evaporated cds thin films have been investigated. cds thin film deposited by electron beam evaporation method in 12nm/min and 60nm/min evaporation rates on glass substrates. x-ray diffraction, scanning electron microscopy, uv-vis-nir spectroscopy and atomic force microscopy were used to character...

as we know sol-gel is one of the most important techniques for thin film preparation. in this paper, high transmission silica thin films have been prepared by dip-coating process from a new silicon-alkoxide solution. the prepared sol was stable for 45 days which is very important to characterize the coating process. the optical properties as a function of aging time, withdrawal rate, and heat t...
