Finely tuning crystallinity and doping of hydrogenated microcristalline silicon thin films is a keypoint into obtaining high quality devices for above integrated circuit (above-IC) image sensors. This study focuses on the structural and electrical properties of RF-PECVD deposited microcrystalline silicon (µc-Si:H) contact layers. In this work, phos...
A major cause of ultrafiltration (UF) membrane fouling in surface water treatment is natural organic matter (NOM). Some studies have reported that heated aluminum oxide particles (HAOPs), prepared by boiling a suspension containing precipitates of the common coagulant alum, can remove substantial amounts of NOM and reduce fouling when they were pre...

The electrochemical oxidation of ammonia was done at electrochemically Pt-modified microcrystalline and polycrystalline boron-doped diamond (BDD) thin films from sp3 Diamond Technologies and Element Six. The Pt electrodepositions were done by chronoamperometry and cyclic voltammetry using a 1 mM K2PtCl6 solution in 0.5 M H2SO4. The Pt-BDD electrode...

Constraining magmatic and eruptive processes is key to understanding how volcanoes operate. However, reconstructing eruptive and pre-eruptive processes requires the ability to see through any post-eruptive modification of the deposit. The well-preserved Grey’s Landing ignimbrite from the central Snake River Plain provides an opportunity to systemat...

Akebia Saponin D (ASD) or asperosaponin VI is the most abundant constituent of the rhizome of Dipsacus asper, which has been used for the treatment of lower back pain, traumatic hematoma and bone fractures. In recent years, it was reported that ASD was a potential treatment strategy for Alzheimer's disease (AD). However, the low bioavailability of ...

Using the high working pressure plasma-enhanced chemical vapor deposition (HWP-PECVD) technique, the hydrogenated microcrystalline silicon (μc-Si:H) films for photovoltaic layers of thin film solar cells was investigated. The μc-Si:H films were deposited on surface textured fluorine-doped tin oxide (FTO) glass substrates at 100 Torr in a 100 MHz ve...

Radial n-i-p structure silicon nanowire (SiNW)-based microcrystalline silicon thin-film solar cells on stainless steel foil was fabricated by plasma-enhanced chemical vapor deposition. The SiNW solar cell displays very low optical reflectance (approximately 15% on average) over a broad range of wavelengths (400 to 1,100 nm). The initial SiNW-based ...

This paper presents a possible diagnostic method to be applied in the grinding process using the acoustic emission signal (AE) and image analysis. The applied method of the experimental results in computer analysis using the system of tracking changes occurring within the image, as well as the experimental results obtained for single-pass internal ...
An overview on microstructural and electronic properties of stoichiometric microcrystalline silicon carbide (mu c-SiC) prepared by Hot-Wire Chemical Vapor Deposition (HWCVD) at low substrate temperatures will be given. The electronic properties are strongly dependent on crystalline phase, local bonding, strain, defects, impurities, etc. Therefore t...
Successful p-type doping of mu c-SiC:H with Al introduced from trimethylaluminum has been already demonstrated. In this work we focus on the influence of substrate temperature (T-s =300-390 degrees C) on the Al-doping. As T-s is reduced from 390 degrees C to 300 degrees C, the crystallinity decreases from 75% to 55% and the dark conductivity sigma(...
