Abstract Magnesium titanate (MgTiO 3 ) has been successfully synthesized via the sonochemical method by using TiO 2 (P25) and Magnesium nitrate (MgNO 3 ) 2 .6H 2 O as precursors without any additional phases such as MgTi 2 O 5 and Mg 2 TiO 4 . The synthesized nanoparticles were well characterized by optical methods using UV‐Vis diffuse reflectance spectroscopy (DRS) and Photoluminescence spectroscopy (PL). The morphology of MgTiO 3 nanoparticles is irregular in shape with serious agglomerations were confirmed through SEM analysis. XRD confirms crystal structure and phase purity of MgTiO 3 nanoparticles calcined at 700 °C for 2 hours. The calculated band gap energy of MgTiO 3 nanoparticles has been found to be 3.05 eV. Using the prepared MgTiO 3 nanoparticles, the photocatalytic activities were evaluated by following the degradation of Congo red dye under visible light. Moreover, the influence of various scavengers on the photocatalytic reaction were studied.
In this communication, we report that a Co-doped NiSe2 nanoparticles film electrodeposited on a conductive Ti plate (Co0.13Ni0.87Se2/Ti) behaves as a robust electrocatalyst for both HER and OER in strongly basic media, with good activity over a NiSe2/Ti counterpart. This Co0.13Ni0.87Se2/Ti catalytic electrode delivers 10 mA cm(-2) at an overpotential of 64 mV for HER and 100 mA cm(-2) at an overpotential of 320 mV for OER in 1.0 M KOH. A voltage of only 1.62 V is required to drive 10 mA cm(-2) for the two-electrode alkaline water electrolyzer using Co0.13Ni0.87Se2/Ti as an anode and cathode.

Herein, the detection of aspartic acid by doped Co<sub>3</sub>O<sub>4</sub>-ZnO nanorod materials was proposed using differential pulse voltammetry. The nano-composite metal oxide was synthesized by the wet precipitation method in basic media. Aspartic acid is a non-essential amino acid naturally synthesized in the body with lot of health significance, including as a biomarker for several health deficiencies. The synthesized composite Co<sub>3</sub>O<sub>4</sub>-ZnO nanorod was well-investigated by using FESEM, XRD, XPS, FTIR, UV/vis., EIS, and CV. The synthesized composite exhibited a low limit of detection (0.03 µM, high sensitivity (0.0014 µA µM<sup>-1</sup> cm<sup>-2</sup>) and wide linear range (0.05-50 µM) for aspartic acid. The substrate, the Co<sub>3</sub>O<sub>4</sub>-ZnO nanorod, enhanced the electro-catalytic oxidation of aspartic acid as a result of its catalytic and conductivity properties. The developed sensor based on Co<sub>3</sub>O<sub>4</sub>-ZnO has a repeatable, reproducible and stable current response for aspartic acid. Additionally, other electroactive compounds did not interfere with the sensor's current response. The suitability of the developed sensor for real sample analysis was also established. Therefore, this study proposed the potential use of Co<sub>3</sub>O<sub>4</sub>-ZnO nanorod material in healthcare management for the maintenance of human well-being.

Polyethylene glycol (PEG) displayed an amazing properties when mixed with other polymers or inorganic materials. Polymers of different types (organic, inorganic or hybrid) and a variety of inorganic materials have been blended and showed interesting properties. So that, a new experimental design of PEG / MCM-41composites has been prepared using different loading from PEG. MCM-41 as one of the most important mesoporous material has been used as support material. The preparation process for the new composites has been carried out using a simple dissolution method. Freshly prepared MCM-41 has been investigated by simple characterisation tools. The obtained structure of the new composites was promoted by various characterization techniques. which including: Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), and thermal analyses have been used as characterization tools. Moreover, the electrical properties were measured using electrical conductivity measurements. SEM images showed nearly the same globular grain in both cases for pure MCM-41 and PEG / MCM-41(10%) composite. Whereas PEG / MCM-41(30%) composite showed different feature. The increasing the PEG percentage till 20 % was accompanied by a continuous decrease of the WL %.
