Self-Reporting Conjugated Polymer Nanoparticles for Superoxide Generation and Detection.

Conjugated polymer nanoparticles (CPNs or Pdots) have become increasingly popular fluorophores for multimodal applications that combine imaging with phototherapeutic effects. Reports of CPNs in photodynamic therapy applications typically focus on their ability to generate singlet oxygen. Alternatively, CPN excited states can interact with oxygen to form superoxide radical anion and a CPN-based hole polaron, both of which can have deleterious effects on fluorescence properties.

Self-Supported Mn-NiSe Electrocatalysts for Water and Urea Electrolysis for Energy-Saving Hydrogen Production.

Recently, there has been a huge research interest in developing robust, efficient, low-cost, and earth-abundant materials for water and urea electrolysis for hydrogen (H) generation. Herein, we demonstrate the facile hydrothermal synthesis of self-supported Mn-NiSe on Ni foam for overall water splitting under wide pH conditions. With the optimized concentration of Mn in NiSe, the overpotential for hydrogen evolution, oxygen evolution, and urea oxidation is significantly reduced by an enhanced electrochemical active surface area.

Synergistically Driven CoCr-LDH@VNiS as a Bifunctional Electrocatalyst for Overall Water Splitting and Flexible Supercapacitors.

Utilizing alternative energy sources to fossil fuels has remained a significant issue for humanity. In this context, efficient earth-abundant bifunctional catalysts for water splitting and energy storage technologies like hybrid supercapacitors have become essential for achieving a sustainable future. Herein, CoCr-LDH@VNiS was synthesized by hydrothermal synthesis.

Repostioning of Telemedicine in Cardiovascular World Post-COVID-19 Pandemic.

Background: During the COVID-19 pandemic, telemedicine is a quickest expanding service solution to provide improved access to sophisticated healthcare that is efficient, cost-effective, and time-consuming.

Methods: This analysis is evaluated on the basis of several studies that look at the history, benefits, various techniques, challenges, uses, and impact of telemedicine in the treatment of heart failure and cardiac rehabilitation as during COVID-19 outbreak.

Results: Patients avoided or refused medical treatment during COVID-19 pandemic despite the risk of illness and the threat of infections spreading.

ab initio Energetics and Thermoelectric Profiles of Gallium Pnictide Polytypes.

The state-of-the-art Density Functional Theory (DFT) is utilized to investigate the structural, electronic, vibrational, thermal and thermoelectric properties of gallium pnictides GaX (X = P, As, Sb) in cubic zincblende (ZB) and hexagonal wurtzite (WZ) phases. The lattice parameters, bulk modulus, energy band nature and bandgap values, phonon, thermal and thermoelectric properties are revisited for ZB phase while for WZ phase they are predictive. Our results agree reasonably well with the experimental and theoretical data wherever they are available.
