Indium tin oxide (ITO) and titanium dioxide (TiO2) anti-reflective coatings (ARCs) were deposited on a (100) P-type monocrystalline Si substrate by a radio-frequency (RF) magnetron sputtering. Polycrystalline ITO and anatase TiO2 films were obtained at room temperature (RT). The thickness of ITO (60 to 64 nm) and TiO2 (55 to 60 nm) films was optimized, considering the optical response in the 40...

استفاده از نیمه هادی های اکسیدی، برای ساخت ادوات مختلف نظیر حسگر¬های گاز و سلول¬های خورشیدی، حائز اهمیت بوده و همواره مورد مطالعه واقع شده است. در این میان برای افزایش حساسیت حسگرها از روش¬های مختلفی مانند پیش رفتن به سمت ساختار¬های در مقیاس نانو، افزودن ناخالصی و یا اضافه کردن لایه¬هایی از فلزات نجیب به نیمه¬هادی اکسیدی استفاده می¬شود. کار حاضر با هدف افزایش حساسیت حسگر گاز اکسید ایندیم آلایش ...

Nano-scale surface roughness in transparent ITO films was artificially formed by sputtering a mixed Ag and ITO layer and wet etching of segregated Ag nanoparticles from the surface of the ITO film. Effective removal of self-segregated Ag particles from the grain boundaries and surface of the crystalline ITO film led to a change in only the nano-scale surface morphology of ITO film without chang...

The Ito cell (fat-storing cell) lies in perisinusoidal space of liver and has a variety of functions. We investigated the immunohistochemistry and ultrastructure of Ito cells in normal and cholestatic livers of broiler chickens. Immunohistochemistry demonstrated that Ito cells expressed HHF35 muscle actin, vimentin, desmin, glial fibrillary acidic protein (GFAP), neuron-specific enolase (NSE), ...

Polystyrene sphere was chosen as a catalyst to fabricate indium-tin-oxide (ITO) nanowires (NWs) with a low-temperature (280-300 °C) electron-beam deposition process, bearing high purity. The ITO NWs with diameter of 20-50 nm and length of ~2 um were obtained. X-ray diffraction and high-resolution transmission electron microscope show high crystal quality. The transmittance is above 90 % at a wa...

Monodisperse indium tin oxide nanoparticles (ITO NPs) with high crystallinity have been synthesized by the rapid thermal injection method and the seed-mediated growth method. We demonstrate that the surface plasmon resonance (SPR) frequencies of ITO NPs can be manipulated from 1,600 to 1,993 nm in near-infrared band by controlling the composition, size, and morphology. The doping Sn concentrati...

Gold nanoparticles (GNP) and RGD peptide modified indium tin oxide (ITO) electrode was fabricated to enhance the electrochemical signals from neural stem cells (HB1.F3). Aminopropyltrimethoxylane (APTMS) was selfassembled on ITO electrode surface to immobilze GNP and its topological characteristics were confirmed by scanning electron microscopy (SEM). Thereafter, cysteine containing RGD peptide...

BACKGROUND Transient outward K currents (Ito) have been reported both to suppress and to facilitate early afterdepolarizations (EADs) when repolarization reserve is reduced. Here, we used the dynamic clamp technique to analyze how Ito accounts for these paradoxical effects on EADs by influencing the dynamic evolution of repolarization reserve during the action potential. METHODS AND RESULTS I...

To evaluate the relationship, both quantitative and qualitative, between the Ito cells and methotrexate (MTX) therapy Ito cells were studied by light microscopy in 1 mum toluidine blue stained sections and by electron microscopy in 24 pairs of Menghini needle biopsies before and after MTX therapy of 24 consenting patients with severe psoriasis. Light microscopy showed a statistically significan...

Organic light-emitting diodes (OLEDs) with a nickel (Ni)-doped indium tin oxide (ITO) anode were fabricated. The Ni-doped ITO anode was prepared using sputter deposition of Ni–ITO single targets consisting of 1, 3 and 5 wt% of nickel. Turn-on voltage of OLED devices with the Ni-doped ITO anode was reduced by 2.5, 4 and 3.8 V for 1, 3 and 5 wt% targets, respectively. Half-luminance lifetime was ...
