Green synthesized CaO decorated ternary CaO/g-CN/PVA nanocomposite modified glassy carbon electrode for enhanced electrochemical detection of caffeic acid.

A highly selective, sensitive caffeic acid (CA) detection based on calcium oxide nanoparticles (CaO NPs) derived from extract of Moringa oleifera leaves decorated graphitic carbon nitride covalently grafted poly vinyl alcohol (CaO/g-CN/PVA) nanocomposite modified glassy carbon electrode (GCE) was studied. A facile sonochemical method was adapted to synthesis nanomaterials and characterized by HR-TEM (High resolution transmission electron microscopy), FT-IR (Fourier transform infrared spectroscopy), XRD (X-ray diffraction), FE-SEM (Field emission scanning electron microscopy), EDX (Energy dispersive X-ray analysis), Mapping and BET (Brunauer-Emmett-Teller) analysis, and electrochemical techniques. The nanocomposite modified GCE exhibited an excellent catalytic performance to the oxidation of CA under optimized conditions owing to better electron transfer efficiency, conductivity and high surface area of the electrode material.

Visible-Light-Driven L.-Mediated Ag-Doped BiZrO Nanocomposite for Enhanced Degradation of Organic Pollutants, Electrochemical Sensing, and Antibacterial Applications.

Novel visible-light-driven Ag ()-doped BiZrO (BZO) nanocomposites in pudina (P) extract ( L.), -1, 3, 5, 7, and 9 mol %, were synthesized by the one-pot greener solution combustion method. The as-synthesized nanocomposite materials were characterized by using various spectral [X-ray diffraction (XRD), Fourier transform infrared, UV-visible, UV- diffuse reflectance spectra, X-ray photoelectron spectroscopy], electrochemical (cyclic voltammetry, electrochemical impedance spectroscopy), and analytical (scanning electron microscopy-energy-dispersive X-ray spectroscopy, transmission electron microscopy, Brunauer-Emmett-Teller) techniques.

Investigation of Corrosion Inhibition of Mild Steel in 0.5 M HSO with Inhibitor Extracted from Rotten Grapefruits (): Adsorption, Thermodynamic, Electrochemical, and Quantum Chemical Studies.

Corrosion inhibition of mild steel (MS) was studied using isolate in 0.5 M HSO, which was isolated from rotten grapes () via biofilm formation. Biofilm over the MS surface was asserted by employing FT-IR and FE-SEM with EDXS, electrochemical impedance spectroscopy (EIS), AFM, and DFT-ESP techniques.

Baseline survey of micro and mesoplastics in the gastro-intestinal tract of commercial fish from Southeast coast of the Bay of Bengal.

Plastics pollution is ubiquitous. Microplastics (<5 mm in diameter) and mesoplastics (5-20 mm in diameter) are emerging as the most common plastic particulates found in the marine environment. In this study, the occurrence of microplastics and mesoplastics in the gastrointestinal tract (GI) of some commercially important fish collected from Chennai and Nagapattinam of Tamil Nadu, Southeast coast of Bay of Bengal was assessed.

'Biofilm Clippers'- enzyme formulation for bovine mastitic biofilm therapy.

Mastitis is one of the most important diseases that are threatening modern dairy farms. Biofilms of mastitic teat canal have serious clinical implications because of colonized pathogens having the ability to construct an extracellular polymeric substance (EPS) with increased tolerance to antimicrobials leads to difficulty in eradicating the infection. In this study, we investigated the synergistic biofilm disruptive effect of a combination of carbohydrate hydrolases targeting extracellular polysaccharides of biofilm matrix and we termed it as 'Biofilm Clippers (BC)'.

Electrochemical sensing of nicotine using CuWO decorated reduced graphene oxide immobilized glassy carbon electrode.

A novel and selective electrochemical sensing of nicotine is studied using copper tungstate decorated reduced graphene oxide nanocomposite (CuWO/rGO) nafion (Nf) immobilized GC electrode (GCE). The CuWO/rGO nanocomposite is synthesized using sonication method and characterized by HR-TEM (High resolution transmission electron microscopy), SEM (Scanning electron microscopy), FT-IR (Fourier transform infrared spectroscopy), SAED (Selected area of electron diffraction pattern), XRD (X-ray diffraction), Raman spectroscopy, Thermo gravimetric analysis (TGA) and EDX (Energy dispersive X-ray diffraction) techniques. The CuWO/rGO/Nf immobilized GCE shows better electrocatalytic response for the detection of nicotine as compared to bare GCE.

Cryptic speciation in the mesopelagic environment: molecular phylogenetics of the lanternfish genus Benthosema.

The presence of morphologically identical individuals that are genetically divergent, known as cryptic species, is a phenomenon that is likely to be of importance at the theoretical level, for speciation studies, and at the applied level, for management purposes. Cryptic species are probably common in the marine environment, and they have been described in a variety of habitats. Here we present the first case of cryptic speciation in the mesopelagic environment for the Benthosema lanternfishes.

Remote intermittent ischemia before coronary artery bypass graft surgery: a strategy to reduce injury and inflammation?

Perioperative myocardial ischemia contributes to postoperative morbidity and mortality. Remote intermittent ischemia (RI) has been shown to benefit patients undergoing coronary artery bypass graft (CABG) surgery by decreasing postoperative cardiac troponin levels. In addition, there is evidence that volatile anesthetics may provide myocardial protection.
