Physiochemical characterization of sodium doped zinc oxide nano powder for antimicrobial applications.

Zinc oxide (ZnO) is one of the semiconductor materials with unique antimicrobial properties towards various microorganisms. In this article, pure and Na doped ZnO nanopowders were synthesized by easiest and cost-effective co-precipitation process. X-ray diffraction (XRD),Fourier transform infrared spectroscopy(FT-IR), ultraviolet - visible (UV - Vis) spectroscopy, scanning electron microscopy(SEM), and Energy dispersive X-ray analysis (EDAX) techniques were used to characterize the particle size, surface morphology and chemical composition of prepared materials.

Pulmonary delivery of nanostructured lipid carriers for effective repurposing of salinomycin as an antiviral agent.

Coronavirus disease outbreak caused a severe public health burden all over the world. Salinomycin (SAL) is a broad-spectrum antibiotic that had drawn attention in selective targeting of cancer and viral infections. Recent drug screen identified SAL as a potent antiviral agent against SARS-CoV-2.

Self-driven gel conveyer: effect of interactions between loaded cargo and self-oscillating gel surface.

A "self-oscillating" gel that swells and deswells periodically under constant conditions is developed as a novel biomimetic gel differing from conventional stimuli-responsive polymer gels. By utilizing the peristaltic motion of the self-oscillating gel, autonomous mass-transport systems can be realized. With the propagation of the chemical wave, the loaded gel cargo is autonomously transported by rotating on the surface.

Solvothermal synthesis of bismuth molybdate hollow microspheres with high photocatalytic activity.

Bi2MoO6 hollow microspheres were successfully synthesized by a simple solvothermal process without using any hard template or surfactant. The effect of solvent and urea on the morphology of the samples was studied systematically. The results indicate that the composition of the mix ethylene glycol/absolute ethanol solvents and the urea content play a key role in the final formation of hollow microspheres.

A highly sensitive hydrogen peroxide amperometric sensor based on MnO2-modified vertically aligned multiwalled carbon nanotubes.

In this report, a highly sensitive amperometric sensor based on MnO(2)-modified vertically aligned multiwalled carbon nanotubes (MnO(2)/VACNTs) for determination of hydrogen peroxide (H(2)O(2)) was fabricated by electrodeposition. The morphology of the nanocomposite was characterized by scanning electron microscopy, energy-dispersive X-ray spectrometer and X-ray diffraction. Cyclic voltammetry, chronoamperometry and electrochemical impedance spectroscopy were applied to investigate the electrochemical properties of the MnO(2)/VACNTs nanocomposite electrode.

Highly sensitive detection of explosive triacetone triperoxide by an In2O3 sensor.

Triacetone triperoxide (TATP) is one of the most sensitive known explosives and can be easily synthesized using the commonly available chemicals acetone and hydrogen peroxide, but is difficult to be detected. In this study, In(2)O(3) nanoparticles were synthesized by a glucose-assisted solvothermal method at 120 degrees C for 18 h. The gas sensor based on In(2)O(3) nanoparticles exhibits a high response, fast response and recovery, a wide detecting range of 0.

A highly sensitive nonenzymatic glucose sensor based on CuO nanoparticles-modified carbon nanotube electrode.

In this report, a novel type of cupric oxide (CuO) nanoparticles-modified multi-walled carbon nanotubes (MWCNTs) array electrode for sensitive nonenzymatic glucose detection has been fabricated. The morphology of the nanocomposite was characterized by transmission electron microscopy and X-ray diffraction. The electrochemical performance of the CuO/MWCNTs electrode for detection of glucose was investigated by cyclic voltammetry and chronoamperometry.
