Adopting the concurrent reduction of CuO during hydrothermal preparation of ZnVO, metal-semiconductor heterojunction Cu/ZnVO nanorods were synthesized and applied to the catalytic generation of methanol and ethanol from CO aerated water under UV-vis light irradiation. 10Cu/ZnVO obtained from 10 wt % composite amount of CuO exhibited a total carbon yield of 6.49 μmol·g·h. The yield of CHOH and CHOH reached 3.30 and 0.86 μmol·g·h, respectively. 2.5Cu/ZnVO displayed the highest ethanol yield of 1.58 μmol·g·h due to the strong absorption in the visible light. Cu/ZnVO was characterized using X-ray diffraction (XRD), scanning transmission electron microscopy (STEM), X-ray photoelectron spectroscopy (XPS), ultraviolet-visible (UV-vis) spectra, photoluminescence (PL) spectra, transient photocurrent response, and electrochemical impedance spectroscopy (EIS). Results showed that composite Cu-ZnVO increased the surface area and tuned the energy band position, which matches the reaction potential toward methanol and ethanol. The photocatalytic activity toward CHOH and CHOH on Cu/ZnVO is attributed to faster transmission and a slow recombination rate of photogenerated carriers at the heterojunction interface. Multielectron reactions for the production of CHOH and CHOH are promoted. Free radical capture experiments indicated that the active species boost the reaction in the order of OH > e > h.

Plants are the rich source of biologically active compounds which can be obliging against various pathogenic microorganisms and cancerous diseases. The current study evaluated the antibacterial potential of aqueous, methanol, ethanol, and acetone extracts of Malus domestica (apple), Cinnamomum verum (cinnamon) and Trachyspermum ammi (ajwain) via agar well diffusion methods and minimum inhibitory concentration (MIC) in (mm) against Staphylococcus aureus (ATCC 25923) and Salmonella typhi (ATCC 19430). The antioxidant properties including total phenolic content (TPC), total flavonoid content (TFC), DPPH and reducing power was determined by UV/VIS spectrophotometery and all the results interpreted through one way ANOVA (STATISTICA).

Purpose: Acanthamoeba species are eucaryotic protozoa found predominantly in soil and water. They cause ulceration and vision loss in the cornea (Acanthamoeba keratitis) and central nervous system (CNS) infection involving the lungs (granulomatous amoebic encephalitis). Antiparasitic drugs currently used in the treatment of infections caused by Acanthamoeba species are not effective at the desired level in some anatomical regions such as the eye and CNS.

Methanol (CH₃OH) is a volatile, transparent, and toxic substance widely used in chemical substrates, antifreeze, and industrial applications. Ethanol (C₂H₅OH), in contrast, is commonly used in alcoholic beverages, as a fuel additive, and as an antiseptic. Differentiating between methanol and ethanol is critical due to the severe health risks associated with methanol ingestion, while ethanol is safe for consumption in moderation.

Species of genus are known to be rich sources of bioactive compounds. However, there is a lack of studies comparing extraction methods for these bioactive components. This study aimed to compare the total phenolic contents, total antioxidant capacity, tyrosinase inhibitory effect, sargahydroquinoic acid (SHQA) and sargachromenol (SCM), two algal meroterpenoids, of extracts acquired by different extraction methods.

A novel yeast species, isolated from the bark of pine trees in Gyeongju, South Korea, and designated as KCTC 37304 (ex-type KACC 410729), is characterized by its genetic, morphological and physiological properties. Molecular phylogenetic analysis involving the D1/D2 domain of the 26S LSU rRNA gene and the internal transcribed spacer (ITS) region confirms that it belongs to the genus . In comparison to CBS:10065, the type strain of its closest relative, KCTC 37304 exhibits 8 nucleotide substitutions (~2.
