As an important quality index of high voltage electricity transmission tower, zinc coating thickness detection and quality control is more and more attention in recent years. The coating thickness and uniformity of tower materials provided by the suppliers are tested through the traditional method by the power department, the detection precision of this method is low efficiency and analysis res...

In this study, the microstructural, mechanical, adhesion, and hemocompatibility properties of nanocrystalline diamond coatings were examined. Microwave plasma chemical vapor deposition (MPCVD) was used to deposit nanocrystalline diamond coatings on silicon (100) substrates. The coating surface consisted of faceted nodules, which exhibited a relatively wide size distribution and an average size ...

and Introduction: There are currently no electrically-pumped semiconductor lasers that can operate in the 1-5 terahertz (THz) spectral range at room temperature. An alternative method of producing room temperature THz light is based on intra-cavity difference frequency generation (DFG) in dual wavelength mid-infrared quantum cascade lasers. Our THz DFG sources can provide tunable output of over...

This contribution regards the Radio Frequency (RF) transmission line of the Megavolt ITER Injector and Concept Advancement (MITICA) experiment. The original design considered copper coaxial lines of 1″ 5/8, but thermal simulations under operating conditions showed maximum temperatures of the lines at regime not compatible with the prescription of the component manufacturer. Hence, an optimizati...

Cellulose nanofibril (CNF) suspensions are not easily coatable because of their excessively high viscosity and yield stress, even at low solids concentrations. In addition, CNF suspensions vary widely in their properties depending on the production process used, which can affect their processability. This work reports roll-to-roll coating of three different types of CNF suspensions with a slot-...

In this study, Damar Batu (DB) − a novel biomaterial− is evaluated for its potential application in pharmaceutical coating. DB is a whitish to yellowish resin, characterized initially in terms of solubility, acid value, molecular weight (Mw), polydispersity index (Mw/Mn) and glass transition temperature (Tg). Neat plasticized films of DB are investigated for mechanical, water vapor transmission...

Anatase phase containing nano-crystallite TiO2 thin film is prepared by the peptization of modified Ti-isopropoxide sol using HNO3 as peptizing agent. The resulting sol is concentrated in a rotary evaporator bath. TiO2 film is deposited on ITO substrate by spin coating process. The compact film is annealed at 450 ̊C and 500 ̊C for optical studies. The subsequently it is modified as photo-anodes i...

Quartz fibers are used in high energy physics experiments as the active medium in high radiation area calorimetry. Quartz fibers are also used in the transmission of optical signals. Even though quartz does not damage by moderate amounts of irradiation, the clad of the fibers and the protective coating (buffer) do damage reducing light transmission. Various types of quartz fibers have been irra...

Coating or encapsulation of nanoparticles is a major challenge due to the extremely small size, high surface energy, and high surface area of the nanoparticles. In this paper we describe a new method using supercritical CO2 as an anti-solvent (SAS) for nanoparticle coating/encapsulation. A model system, using silica nanoparticles as host particles and Eudragit polymer as the coating material, w...
