Abstract null null Nickel oxide (NiO) nanoparticles (NPs) were synthesized by a sol-gel method and calcination at 200°C. The modified carbon paste electrode with NiO NPs showed an increased current in the presence of loratadine (Lor). Thus, the experimental design using the response surface methodology (RSM) approach was applied to study the interaction effects of binary variables in the electrode's response in the square wave voltammetric (SqW) determination of Lor. The optimized run included b...

Abstract null null In this work, the carbon (C) and silicon (Si) doping and codoping effects on null null null β null null -arsenene (As) monolayer structural, electronic, and magnetic properties have been comprehensively investigated using first-principles calculations. The studied two-dimensional (2D) materials exhibit good stability. Pristine null null null β null null -As single layer is an indirect gap semiconductor with a band gap of 1.867(2.441) eV as determined by PBE(HSE06) functional. ...

Abstract null null In this work, we report the synthesis of copper oxide (CuO) nanowires on indium tin oxide (ITO) coated with a few–layers of MoS2 flakes by the thermal annealing and metal–organic chemical vapour deposition (MOCVD) methods at a temperature of 200 °C. As a result, the CuO/MoS2 photocathode gave the maximum photocurrent density (PCD) of −9.8 mA/cm2 (η = 0.75%) at –1.2 V (vs. RHE), which is higher than that of the pristine CuO nanowires photocathode (−6.08 mA/cm2, η = 0.44%). The ...

Abstract null null Numerous studies have been conducted in the recent years for the practical application of triboelectric nanogenerators (TENGs). The underlying concept of TENG is to convert the inexhaustible kinetic energy obtained from natural sources into mechanical energy for triboelectricity. Among these energy sources, wind energy occurs freely throughout the world and can be easily transformed through mechanical motion. This study proposes a ventilator integrated TENG (VTENG) capable of ...

Abstract null null Flower-like BiOI/Bi5O7I type-II heterojunctions with oxygen vacancies (OVs) have been in-situ constructed by calcining flower-like BiOI obtained by a hydrothermal tactic with the assistance of water hyacinth powder (WHP). The photocatalysts were characterized by specific surface area, X-ray diffraction pattern (XRD), scanning electron microscope (SEM), high-resolution transmission electron microscopy (HRTEM), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and elect...
ABSTRACT null null We propose a facile solid-state colorimetric approach towards the selective optical recognition of Co(II), using a chromoionophoric molecular ion-receptor i.e., (E)-2-(4-(diethylamino)-2-hydroxybenzylidene)-N-phenylhydrazine-1-carbothioamide (DEHPC) uniformly decorated on a bimodal meso-/macro-porous polymer monolith. The surface morphology and structural features of the polymer monolith template and its probe impregnated sensor material are characterized using HR-TEM, FE-SEM,...

Abstract null null An original, simple and cost-effective oxidation strategy to attain thermochromic vanadium dioxide thin films is reported. This two-step procedure comprises the initial deposition of DC magnetron-sputtered vanadium or vanadium oxide films by the combination of glancing angle deposition and, if needed, reactive gas pulsing process, followed by fast oxidation of such layers in air atmosphere at high temperatures. Thanks to the careful control of the thermal treatment parameters,...

Abstract null null Packaging production often includes varnishing to increase printed information durability. In addition, as some materials cannot be recycled (which could be the case in food packaging), the use of biobased materials enables waste to be composted. This paper proposes biopolymer-based nanocomposite coating which could be applied onto the printed paper substrate to protect it and increase its barrier properties to the water vapour. For the purpose of the research, two sets of the...

Abstract null null Recent studies showed that plant extracts enhance the antibacterial activity of conventional antibiotics. Those extracts could be used to synthesize nanoparticles for producing antibiotics with better results against microbial infections. We selected the medicinal plant Argemone mexicana L. and evaluated its antibacterial activity. An extract of this plant was used for synthesizing gold and silver nanoparticles. The antibacterial activity of nanoparticles was tested against pa...
