An efficient antireflection coating is critical for the improvement of silicon solar cell performance via increased light coupling. Here, we have grown well-aligned ZnO nanowhisker (NW) arrays on Czochralski silicon solar cells by a seeding-growth two-step process. It is found that the ZnO NWs have a great effect on the macroscopic antireflection effect and, therefore, improves the solar cell p...

Liquid atomization is applied in nanostructure dense coating technology to inject suspended nano-size powder materials into a suspension plasma spray (SPS) torch. This paper presents the effects of the atomization parameters on the nanoparticle processing. A numerical model was developed to simulate the dynamic behaviors of the suspension droplets, the solid nanoparticles or agglomerates, as we...

Novel carbon-coated MoO(2) nanofibers have been fabricated through a controlled route based on single-nozzle electrospinning, air stabilization, and reduction/carbonization processes. They are composed of both a uniform carbonaceous shell of ∼3 nm in thickness and a hierarchical core made of primary MoO(2) nanocrystal clusters of ∼20 nm in size. Importantly, the electrode made of such unique ca...

This paper reviews the development of coronary stents from a polymer scientist's view point, and presents the first results of an interdisciplinary team assembled for the development of new stent systems. Poly(styrene-b-isobutylene-b-styrene) block copolymer (SIBS), a nanostructured thermoplastic elastomer, is used in clinical practice as the drug-eluting polymeric coating on the Taxus coronary...

Coral Pt islands films are deposited via electrochemical reduction on silica-coated nanostructured Ag electrodes. From these devices surface-enhanced (resonance) Raman [SE(R)R] signals of molecules exclusively attached to Pt are obtained with intensity up to 50% of the value determined for Ag. SE(R)R spectroscopic investigations are carried out with different probe molecules, silica-coating thi...

The study of new nanostructured transparent materials in order to control the permeability properties of the objects is a very interesting field of research due to its enormous applications in optical and electronics among others. With the aim of achieving superhydrophilic coatings it is very important to control some coating parameters such as the water affinity of the coating materials and th...

Immediate loading of dental implants is only possible if a firm bone-implant anchorage at early stages is developed. This implies early and high bone apposition onto the implant surface. A nanostructured coating material based on an osseoinductive bone grafting is investigated in relation to the osseointegration at early stages. The goal is to transmit the structure (silica matrix with embedded...

The article is devoted to the actual problem of creating damping steels with a nanostructured coating. object research used for manufacture gears, rims, half-couplings, gears and generating noise that creates acoustic discomfort. main idea ​​the work assess acoustic, vibration, physical-mechanical properties steels, obtain coating increased properties, which reduce vibration. During work, (soun...

Synthesis technologies and mechanisms of action nanostructured monocrystalline coatings using ion-plasma have been viewed. This coating builds up a strong boundary layer on working surfaces heavily loaded friction units, which provides the lubricant with high antifriction properties generated by triboprocess in lubrication mode.

Fabrication and organosilane-functionalization and characterization of nanostructured ITO electrodes are reported. Nanostructured ITO electrodes were obtained by electron beam evaporation, and a subsequent annealing treatment was selectively performed to modify their crystalline state. An increase in geometrical surface area in comparison with thin-film electrodes area was observed by atomic fo...
