In the process of electrochemical deposition of metals, the additives can directly affect the final morphology of the metal. Using glyphosate as the additive, copper thin films were prepared by the electrochemical deposition method from a CuSO aqueous solution under a specific voltage. The copper thin films were grown on the surface of the indium tin oxide (ITO) film, which was used as the working electrode in a classical three-electrode cell. Glyphosate combined with the copper ion to form a complex, and hindered further reduction and crystallization of the copper ions. The results indicated that the peak intensities of the X-ray diffraction peaks decreased with the increase in the glyphosate concentrations, which can be used as a basis for quantitative detection. The method is simple and highly sensitive.

Aqueous zinc-ion batteries (AZIBs) stand out among many energy storage systems due to their many merits, and it's expected to become an alternative to the prevailing alkali metal ion batteries. Nevertheless, the cumbersome manufacturing process and the high cost of conventional separators make them unfavorable for large-scale applications. Herein, inspired by the unique nature of cellulose and ZrO, a Janus cellulose fiber (CF)/polyvinyl alcohol (PVA)/ZrO separator is prepared via the vacuum filtration method.

Zeolite coatings are studied as molecular sieves for membrane separation, membrane reactors, and chemical sensor applications. They are also studied as anticorrosive films for metals and alloys, antimicrobial and hydrophobic films for heating, ventilation, and air conditioning, and dielectrics for semiconductor applications. Zeolite coatings are synthesized by hydrothermal, ionothermal, and dry-gel conversion approaches, which require high process temperatures and lengthy times (ranging from hours to days).

Objectives: Nonenzymatic biosensor-based-conductive polymers like polyaniline are highly electrochemically stable, cheap, and easy to synthesize biosensors, which is the main objective of research as well as testing applied in different pH conditions to get optimum sensitivity.
Methods: A nonenzymatic glucose biosensor based on polyaniline was electrochemically deposited on a glassy carbon electrode; the cyclic voltammetry under range applied voltage -0.2 to 1.

One of the most effective ways to solve the problems caused by the presence of steel implants in the body is to apply a coating to them. This study aims to develop and optimize composite coatings of magnesium oxide (MgO), 58S bioactive glass (BG), and N-carboxymethyl chitosan (N-CMC) on stainless steel (SS316L) substrates using the electrophoretic deposition (EPD) method. The synthesized materials were characterized using FTIR, XRD, and SEM to confirm their structure and morphology prior to coating.

The current study investigates and compares the biological effects of ultrathin conformal coatings of zirconium dioxide (ZrO) and vanadium pentoxide (VO) on osteoblastic MG-63 cells grown on TiO nanotube layers (TNTs). Coatings were achieved by the atomic layer deposition (ALD) technique. TNTs with average tube diameters of 15, 30, and 100 nm were fabricated on Ti substrates (via electrochemical anodization) and were used as primary substrates for the study.
