Intrinsically chiral thermoresponsive assemblies from achiral clusters: enhanced luminescence and optical activity through tailor-made chiral additives.

Chiral metal clusters, due to their intriguing optical properties and unique resemblance in size to biomolecules, have attracted a lot of attention in recent times as potential candidates for application in bio-detection and therapy. While several strategies are reported for the synthesis of optically active clusters, a facile approach that enhances a multitude of properties has remained a challenge. Herein, we report a simple strategy wherein the use of a chiral cationic surfactant, during the synthesis of achiral clusters, leads to the fabrication of chiral assemblies possessing enhanced luminescence and optical activity.

A Systematic Review and Meta-Analysis of the Efficacy and Safety of Combined Mechanical Circulatory Support in Acute Myocardial Infraction Related Cardiogenic Shock.

Background: Acute myocardial infarction-related cardiogenic shock (AMICS) is a severe complication associated with exceedingly high mortality rates. While mechanical circulatory support (MCS) has emerged as a potential intervention, the evidence base for independent MCS use remains weak. In contrast, systematic reviews of observational studies have revealed significant mortality reduction when a combination of MCS was used: VA-ECMO in conjunction with a left ventricular (LV) unloading device (Impella or IABP).

Phyto-metabolomic investigation of biologically active fraction of leaf.

Abiotrophia defectiva: A Rare Causative Agent of Infective Endocarditis With Severe Complications.

Infective endocarditis (IE) primarily affects the endocardium of the heart valves. One of the common neurological complications of IE is the embolization of endocardial vegetation, which can obstruct the cerebral arteries. We describe the case of a 47-year-old male patient who developed neurological symptoms as a complication of IE.

Reconfiguration of Intrinsic Depletion-Mode Characteristics of MoS Field-Effect Transistors to High-Performance Enhancement-Mode Operation Using an Argon Plasma-Induced p-Type Doping Technique.

The intrinsic n-type behavior and unavailability of the appropriate p-type doping method for MoS allows only n-type conduction with depletion mode (D-mode) characteristics and forbids the implementation of p-type field-effect transistors (FETs). The D-mode characteristic results in a high off-current (I) at zero gate bias, which limits the usage of MoS FETs for industry-scale (n-channel metal-oxide semiconductor) NMOS/(complementary metal-oxide semiconductor) CMOS-logic-based applications due to significant power dissipation. Both these issues, i.
