Dual Porphyrin Sensitized Photocatalytic System for Visible‐Light‐Driven CO 2 Reduction

Dye‐sensitized photocatalysis offers a powerful strategy for combining the molecular selectivity of transition‐metal catalysts with the robustness and charge‐separation capabilities of semiconductor materials. Herein, we report a dual porphyrin–sensitized TiO 2 platform for visib...

Structure and ac conductivity of K-for-Na ion-exchanged sodium borate glasses

This work addresses structural and ionic transport properties of ion-exchanged borate glasses at temperatures below the glass transition, T g . Analysis of the infrared reflectance spectra of the K-for-Na ion-exchanged glass 0.3Na 2 O-0.7B 2 O 3 revealed short-range order structu...

Mechanical and Electrical Properties of Red Blood Cells Under Oxidative Stress Using Optical Tweezers

Abstract Red blood cells (RBCs) rely on their mechanical and electrostatic properties to maintain microvascular circulation and oxygen delivery. Oxidative stress, a hallmark of many diseases, disrupts these properties by damaging membrane lipids and cytoskeletal proteins. In this...

A ComputationalStudy on Type-I Sn Clathrateswith Inorganic and Organic Guests

Abstract Semiconducting clathrates are a class of inclusion compounds where monatomic cations or anions are encapsulated in a framework made mainly of Si, Ge, Sn, and Sb atoms. In this study, we use density functional theory (DFT) computations to investigate a series of type-I cl...
