Metal chalcogenide quantum dots for photochemical and electrochemical hydrogen generation: recent advancements and technological challenges.

The performance of heterogeneous catalysis, specifically photochemical and electrochemical hydrogen evolution reaction (HER) fundamentally relies upon the prudent choice of catalytic systems with ideal optoelectronic and surface properties. Progressive research in materials processing has hinted at the large-scale applicability of two-dimensional (2D) materials for achieving higher activity in the HER process. Among 2D materials, transition metal chalcogenides (TMCs) have emerged as the advanced materials to enhance the rate of HER on account of their layered structure and chalcogen-sites that exhibit favorable hydrogen binding energies.

Physicochemical Modulations in MXenes for Carbon Dioxide Mitigation and Hydrogen Generation: Tandem Dialogue between Theoretical Anticipations and Experimental Evidences.

The dawn of MXenes has fascinated researchers under their intriguing physicochemical attributes that govern their energy and environmental applications. Modifications in the physicochemical properties of MXenes pave the way for efficient energy-driven operations such as carbon capture and hydrogen generation. The physicochemical modulations such as interface engineering through van der Waals coupling with homo/hetero-junctions render the tunability of optoelectronic variables driving the photochemical and electrochemical processes.

Left Ventricular Hypertrophy Regression Following Transcatheter Aortic Replacement: A Comparison of Self-Expanding Versus Balloon-Expandable Prostheses.

There are limited reports on the impact of prosthesis-patient mismatch (PPM) on the regression of left ventricular hypertrophy (LVH) after transcatheter aortic valve replacement (TAVR). We compared the relative effects of supra-annular, self-expanding (SE) versus intra-annular, balloon-expandable (BE) prostheses on TAVR LVH regression. Regression of left ventricular mass index (LVMi) was evaluated in 168 consecutive TAVR patients, including 60 treated with SE valves (Evolut series) and 108 treated with BE valves (Sapien 3).

Superlative Porous Organic Polymers for Photochemical and Electrochemical CO Reduction Applications: From Synthesis to Functionality.

To mimic the carbon cycle at a kinetically rapid pace, the sustainable conversion of omnipresent CO to value-added chemical feedstock and hydrocarbon fuels implies a remarkable prototype for utilizing released CO. Porous organic polymers (POPs) have been recognized as remarkable catalytic systems for achieving large-scale applicability in energy-driven processes. POPs offer mesoporous characteristics, higher surface area, and superior optoelectronic properties that lead to their relatively advanced activity and selectivity for CO conversion.
