In in vitro tests, natural coniferous resin from the Norway spruce (Picea abies) is strongly antifungal. In this observational study, we tested the clinical effectiveness of a lacquer composed of spruce resin for topical treatment of onychomycosis. Thirty-seven patients with clinical diagnosis of onychomycosis were enrolled into the study. All patients used topical resin lacquer treatment daily...

Nitrogen (N) and sulfur (S) co-doped activated graphene (N,S-AGR) was prepared by the one-pot pyrolysis of a mixture of graphene oxide (GO), thiourea, and potassium hydroxide (KOH), where thiourea acts as the source of N and S dopants and KOH is the activator for porosity. N,S-AGR with a dopant abundance of 2.8 at% N and 2.3 at% S was then used as a high-activity electrocatalyst in the fabricat...

Establishing the toxicity and exposure consequences of microplastics (MPs) on marine organisms relies nondestructive isolation plastics from biological matrices. MPs are commonly extracted these matrices by chemical digestion using alkali (e.g., potassium hydroxide (KOH) sodium (NaOH)), oxidative hydrogen peroxide (H2O2)) and/or acidic nitric acid (HNO3)) reagents. Although conditions can be hi...

Abstract Graphene (G), as a typical two-dimensional material, is often used an additive for liquid lubricants. However, graphene mostly added to lubricants in one-time manner friction; it mainly exists the form of multilayer agglomerated structures due ??? stacking between sheets, making unable fully exert synergistic lubrication function. Herein, we propose new macroscopic superlubric system g...

Natural rocks of magmatic origin are alternative precursors in alkali-activated materials and provide opportunities the search for more environmentally friendly binders compared to portland cement. The pumice is one these its amorphous structure chemical composition make it candidates as a precursor producing geopolymer binder when finely ground. Since majority reserves located Turkey increases...

Tissue clearing techniques are frequently used in the observation and description of anatomical structures pathways without altering three-dimensional layout specimen. optical promotes preservation structures, which allows study internal anatomy its original position spatial interaction. Among these techniques, Potassium Hydroxide (KOH) maceration is one most widely used. However, histological ...

Fast pyrolysis oils are one source of renewable liquid fuels, which could be used as green fuels in a sustainable manner. The ASTM D664 method used to determine the acidic constituents in petroleum products, lubricants, and biodiesel requires mixtures of isopropyl alcohol (IPA) and toluene as solvent. The ASTM method also uses large quantities of solvents for the total acid number (TAN) determi...

Ferulic acid (FA) is widely used as an antioxidant, e.g., as a Ultraviolet (UV) protectant in cosmetics and in various medical applications. It has been produced by the hydrolysis of γ-oryzanol found in rice bran oil soapstock. In this study, the base-catalyzed, homogenous hydrolysis of γ-oryzanol was conducted using various ratios of potassium hydroxide (KOH) to γ-oryzanol, initial concentrati...

The non-rubber components present in natural rubber latex can contribute to the dark color of dried films and may cause allergic reactions. This project aimed develop light-color with minimal protein contamination. Various additives were incorporated, a leaching procedure was implemented address this issue. evaluation focused on content, changes, swelling properties thin films. Texapon N70 prov...
