Surface texturization is well known as one of the major paths to improve the conversion efficiency of silicon solar cells by increasing the short-circuit current through the enhancement in antireflection property and effective photon trapping. Compared to the antireflection coating, it is more lasting and effective process. The anisotropic texturing of a (100) n-type monocrystalline silicon sur...

Potassium hydroxide (KOH) and sodium (NaOH) are expected to occur in the atmospheres of hot rocky super-Earth exoplanets but a lack spectroscopic data is hampering their potential detection. Using robust first-principles methodologies, comprehensive molecular line lists for KOH NaOH that applicable temperatures up $T=3500$ K presented. The OYT4 list covers 0-6000 cm$^{-1}$ (wavelengths $\lambda...

Gaseous potassium (K) species released from biomass during thermochemical conversion pose challenges to reactors and human health. Photofragmentation tunable diode laser absorption spectroscopy (PF-TDLAS) was used for simultaneous, high-dynamic range measurements of atomic K, hydroxide (KOH) chloride (KCl) in flat flames seeded with KCl salt. An expression the PF-TDLAS signal is presented exper...

biochar and activated carbon, as carbon-rich porous materials, have wide environmental applications. in the present research, rice husk (rh) was used for preparation of biochar at 400, 600, and 800 °c under simple pyrolysis, physically-activated carbon with water steam, chemically-activated carbon with potassium hydroxide (koh), and physiochemically-activated carbon with koh and steam. physical...

The authors report on the fabrication of 200 nm period blazed transmission gratings on silicon-on-insulator SOI wafers. These critical angle transmission CAT gratings require 3–5 m tall freestanding grating bars with a very high aspect ratio 100 and smooth sidewalls. In order to meet the challenging geometrical requirements, they modified and improved our previously reported process for the fab...

PURPOSE To assess the utility of polymerase chain reaction (PCR) in diagnosing fungal keratitis and compare its sensitivity and specificity with those of the conventional microbiologic techniques used in the authors' laboratory. METHODS A prospective nonrandomized investigation was undertaken at a tertiary-care ophthalmic facility to evaluate 40 eyes of 40 patients with presumed fungal kerati...

BACKGROUND Genital warts are the most common viral sexually transmitted disease affecting 1% of the population. A prospective, open-label controlled trial was performed to compare topical 5% potassium hydroxide (KOH) solution with CO2 laser in the treatment of female genital warts. METHODS Seventy patients were enrolled in the study after convenience sampling. Right-sided lesions of the patie...
