This study aims to analyze the phytochemical and antimicrobial-related assays including antibacterial, antifungal, antipellicle, and antibiofilm potential of the root of an alpine medicinal plant (Arnebia euchroma (Royle) I.M.Johnst). Ethanolic, methyl acetate, chloroform, and aqueous extracts of root parts of the A. euchroma plant were prepared. The active metabolites of the root part of the plant were evaluated both qualitatively and quantitatively by GC-MS and HPLC techniques, using ethanolic extract. The antimicrobial potential of A. euchroma was investigated using crude extract, fractions, and AgNPs of the A. euchroma root against two Gram-positive bacteria (Enterococcus, Staphylococcus aureus) four Gram-negative bacteria (Salmonella typhi, Pseudomonas aeruginosa, Escherichia coli, Proteus vulgaris) and five fungal strains (Rhizoctonia, Cuneate fasciculus, Aspergillus niger, Fusarium oxysporum, and Candida auris). All the bacterial strains showed sensitivity toward all the fractions

Deposition of Boron-Doped Thin CVD Diamond Films from Methane-Triethyl Borate-Hydrogen Gas Mixture

Boron-doped diamond is a promising semiconductor material that can be used as a sensor and in power electronics. Currently, researchers have obtained thin boron-doped diamond layers due to low film growth rates (2–10 μm/h), with polycrystalline diamond growth on the front and edge planes of thicker crystals, inhomogeneous properties in the growing crystal’s volume, and the presence of different structural defects. One way to reduce structural imperfection is the specification of optimal synthesis conditions, as well as surface etching, to remove diamond polycrystals. Etching can be carried out using various gas compositions, but this operation is conducted with the interruption of the diamond deposition process; therefore, inhomogeneity in the diamond structure appears. The solution to this problem is etching in the process of diamond deposition. To realize this in the present work, we used triethyl borate as a boron-containing substance in the process of boron-doped diamond chemical vapor deposition. Due to the oxygen atoms in the triethyl borate molecule, it became possible to carry out an experiment on simultaneous boron-doped diamond deposition and growing surface etching without the requirement of process interruption for other operations. As a result of the experiments, we obtain highly boron-doped monocrystalline diamond layers with a thickness of about 8 μm and a boron content of 2.9%. Defects in the form of diamond polycrystals were not detected on the surface and around the periphery of the plate.

Boron is unique among the elements and displays remarkable chemistry in all of its compounds. It is widely distributed in low concentrations throughout the Earth's crust and is nearly always found bound to oxygen in its natural forms. Boron enters the life cycle of plants and animals and is important for the normal growth of plants, and possibly all living things. The vast majority of industrial uses of boron involve boron–oxygen compounds, including metal borates, boric oxide, boric acid, and boric acid esters. These have large‐scale applications in many industries, most notably in the manufacture of glasses, ceramics, and other vitreous materials. Boric acid is a weak Lewis acid that does not display Brønsted acidity in aqueous solution. Condensation of B(OH) 3 and its conjugate base B(OH) 4 − to form polyborate anions in aqueous solution has important implications for the solubilities and other solution properties of metal and nonmetal borate salts and provides the structural basis of numerous natural and synthetic borate compounds. Boric acid reacts with alcohols and other hydroxyl group‐bearing compounds to form esters, which have many industrial uses. Reversible borate ester formation with 1,2‐ and 1,3‐diols provides the basis for crosslinked polymers used in adhesives and oilfield applications as well as the essential biological roles of boron. Although much smaller in scale compared to boron oxides, nonoxide compounds of boron have many important industrial uses. These include refractory compounds, such as boron carbide, boron nitrides, boron phosphides, elemental boron, metal borides, and metal‐boron alloys, as well as nonrefractories such as the boron halides and boron hydrides. Although many nonrefractory compounds, such as boron–sulfur compounds, are yet to find significant industrial uses, they nonetheless exhibit fascinating chemistries.
