Objective: Angina, a prevalent manifestation of coronary artery disease, is primarily associated with inflammation, an established contributor to the pathogenesis of atherosclerosis and acute coronary syndromes (ACS). Various inflammatory markers are employed in clinical practice to predict patient prognosis and optimize clinical decision-making in the management of ACS. This study investigated the prognostic significance of integrating commonly used, easily repeatable inflammatory biomarkers within a multimodal preoperative prediction model in patients presenting with unstable Angina Pectoris (UAP) and intermediate coronary lesions.

  • 2D transition metal dichalcogenide (TMDC) semiconductors, like ZrS and HfS, are promising for sub-10 nm P-type field-effect transistors (FETs), which are crucial for advanced integrated circuits.
  • These new materials offer improved performance over traditional P-type semiconductors, with ZrS and HfS achieving high on-state currents of up to 2000 μA/μm at 10 nm gate lengths and maintaining strong performance even at 5 nm.
  • The research suggests that the unique electronic properties of ZrS and HfS, particularly their favorable hole effective mass, make them strong candidates for future high-performance P-type devices in electronics.

  • Nickel-based catalysts are promising for producing hydrogen through water splitting, but their low conductivity and stability have been significant challenges.
  • The development of Fe-doped nickel oxide/nickel phosphide (Fe-NiO/NiP) as a bifunctional electrocatalyst improves charge transfer and reaction rates due to enhanced interfacial coupling from the Fe doping.
  • The engineered heterojunction and O-Fe-P bond within the catalyst boost its stability and catalytic performance, resulting in notable overpotentials of 242 mV and 141 mV for oxygen and hydrogen evolution, respectively.

Article Synopsis
  • Copper bismuthate (CuBiO) is a potential photocathode for photoelectrochemical water splitting, but its performance is hindered by weak charge transfer and high carrier recombination.
  • By introducing zinc into the synthesis of CuBiO, the researchers improved the material's conductivity and charge transport, resulting in a notable 110 mV increase in photocurrent onset potential.
  • The combination of zinc-induced heterojunctions and doping enhances charge transfer and carrier concentration, which is further validated by experiments showing improved charge separation and faster carrier extraction.

Two-dimensional carbon nitrides (CN) have gained significant attention in various fields including hydrogen energy development, environmental remediation, optoelectronic devices, and energy storage owing to their extensive surface area, abundant raw materials, high chemical stability, and distinctive physical and chemical characteristics. One effective approach to address the challenges of limited visible light utilization and elevated carrier recombination rates is to establish heterojunctions for CN-based single materials ( CN, g-CN, CN, CN, CN, and CN). The carrier generation, migration, and recombination of heterojunctions with different band alignments have been analyzed starting from the application of CN with metal oxides, transition metal sulfides (selenides), conductive carbon, and CN heterojunctions.

The advantages of 2D materials in alleviating the issues of short-channel effect and power dissipation in field-effect transistors (FETs) are well recognized. However, the progress of complementary integrated circuits has been stymied by the absence of high-performance (HP) and low-power (LP) -channel transistors. Therefore, we conducted an investigation into the electronic and ballistic transport characteristics of monolayer BeC, which features quasi-planar hexacoordinate carbons, by employing nonequilibrium Green's function combined with density functional theory.

The selective hydrogenation of alkynes is an important reaction; however, the catalytic activity and selectivity in this reaction are generally conflicting. In this study, ultrafine Pd nanoparticles (NPs) loaded on a graphite-like C N structure with nitrogen defects (Pd/DCN) are synthesized. The resulting Pd/DCN exhibits excellent photocatalytic performance in the transfer hydrogenation of alkynes with ammonia borane.

Millions of families around the world remain vulnerable to water scarcity and have no access to drinking water. Advanced oxidation processes (AOPs) are an effective way towards water purification with qualified reactive oxygen species (ROSs) while are impeded by the high-cost and tedious process in either input of consumable reagent, production of ROSs, and the pre-treatment of supporting electrolyte.
