Reduced-Graphene-Oxide-Based Thin Films: An Alternative Coating for Harsh Space Environments.

Polymeric materials are commonly used as the outermost layer in spacecraft passive thermal control. However, in geostationary earth orbit environments, the polymeric layer is susceptible to environmental hazards, particularly electrostatic charges. In this study, we develop a graphene-based coating on a polymeric polyimide (Kapton) and discuss its suitability in simulated harsh space environments for electrostatic dissipation.

Advancements in sunscreen formulations: integrating polyphenolic nanocarriers and nanotechnology for enhanced UV protection.

Sunscreens are essential in protecting the skin from harmful effects of ultraviolet radiation (UVR). These formulations, designed to absorb, block, or scatter UVR, offer vital protection against skin aging, sunburns, and the development of skin cancers like melanomas. However, some sunscreens, especially those containing organic/chemical compounds, can cause allergic reactions.

Septic Shock Secondary to Tricuspid Valve Vegetation Requiring Surgical Debulking.

Tricuspid valve endocarditis is increasing in incidence owing to the prevalent use of intravenous substances. Although most patients respond well to intravenous antibiotics over the course of six weeks, some patients require surgical intervention. A multilayered approach to diagnosis with both transthoracic and transesophageal echocardiography (TEE) is recommended for optimal diagnosis and management.

Assessing efficacy of instructor based orientation to donning doffing protocols and modifications to doffing area infrastructure in reducing SARS-CoV-2 infection among Doctors assigned to COVID-19 patient care.

Background: We assess the efficacy of orientation programmes for doctors of proper donning, doffing techniques for personal protective equipment (PPE) and safe practices inside the COVID-19 hospital in reducing the COVID-19 infection rate among doctors.

Methods: A total of 767 resident doctors and 197 faculty visits on weekly rotation were recorded over a six month period. Doctors were guided through orientation sessions before their entry into the COVID-19 hospital from 1 August 2020.
