Phytosynthesis of CoO Nanoparticles as the High Energy Storage Material of an Activated Carbon/CoO Symmetric Supercapacitor Device with Excellent Cyclic Stability Based on a NaSO Aqueous Electrolyte.

The benign preparation of cobalt oxide nanoparticles (CoO-NPs) was performed using marine red algae extract () as a simple, cost-effective, scalable, and one-pot hydrothermal technique. The nominated extract was employed as an environmental reductant and stabilizing agent. The resultant product showed the typical peak of CoO-NPs around 400 nm wavelength as ascertained by UV-vis spectroscopy.

Three waves changes, new variant strains, and vaccination effect against COVID-19 pandemic.

It has been more than one year since the first case of the coronaviruses was infected by COVID-19 in China. The world witnessed three waves of the corona virus till now, and more upcoming is expected, whereas several challenges are presented. Empirical data displayed that the features of the virus effects do vary between the three periods.

Effects of exercise in combination with autologous bone marrow stem cell transplantation for patients with type 1 diabetes.

Stem cell therapy is a promising approach for the treatment of type 1 diabetes mellitus (T1D). Previous studies recommended regular exercise for the control of T1D. Experimental studies showed that a combination of stem cells and exercise yielded a better outcome.
