Molybdenum(0)-Tricarbonyl Complex Supported by an Azacalix-pyridine Ligand: Synthesis, Characterization, Surface Deposition and Conversion to a Molybdenum(VI)-Trioxo Complex with O2
Chemistry. 2024 Feb 6:e202303912. doi: 10.1002/chem.202303912. Online ahead of print.ABSTRACTAdsorption of metal-organic complexes on metallic surfaces to produce well-defined single site catalysts is a novel approach combining the advantages of homogeneous and heterogeneous catalysis. To avoid the "surface trans-effect" a dome-shaped molybdenum(0) tricarbonyl complex supported by an tolylazacalix[3](2,6)pyridine ligand is synthesized. This vacuum-evaporable complex both activates CO and reacts with molecular oxygen (O2) to form a Mo(VI) trioxo complex which in turn is capable of catalytically mediating oxygen transfer. Th...

Anaerobic respiration of host-derived methionine sulfoxide protects intracellular Salmonella from the phagocyte NADPH oxidase
Cell Host Microbe. 2024 Jan 24:S1931-3128(24)00008-8. doi: 10.1016/j.chom.2024.01.004. Online ahead of print.ABSTRACTIntracellular Salmonella experiencing oxidative stress downregulates aerobic respiration. To maintain cellular energetics during periods of oxidative stress, intracellular Salmonella must utilize terminal electron acceptors of lower energetic value than molecular oxygen. We show here that intracellular Salmonella undergoes anaerobic respiration during adaptation to the respiratory burst of the phagocyte NADPH oxidase in macrophages and in mice. Reactive oxygen species generated by phagocytes oxidize methioni...

Achieving Long ‐Lived Charge Separated State through Ultrafast Interfacial Hole Transfer in Redox Sites‐Isolated CdS Nanorods for Enhanced Photocatalysis
A barbell-shaped ternary heterostructure with spatially isolated redox active sites facilitates efficient charge separation by effectively withdrawing electrons through molybdenum disulfide (MoS2) at both ends and holes via copper sulfide (Cu2S) on the sidewall of cadmium sulfide (CdS) nanorod, resulting in a long-lived charge separated state and thereby enhancing photocatalysis. AbstractAs opposed to natural photosynthesis, a significant challenge in a semiconductor-based photocatalyst is the limited hole extraction efficiency, which adversely affects solar-to-fuel efficiency. Recent studies have demonstrated that photoca...

Tip ‐based Lithography with a Sacrificial Layer
This study highlights the precise fabrication of gold nanoholes (Au NHs) using tip-based lithography with a sacrificial layer. The resulting Au NHs demonstrate exceptional control, achieving diameters of less than 50 nm and gaps between them as narrow as 15 nm. Additionally, the fabricated array of Au NHs serves multiple purposes, including acting as an etching mask, a catalyst for metal-assisted chemical etching, and a template for surface-enhanced Raman scattering. AbstractThe fabrication of a highly controlled gold (Au) nanohole (NH) array via tip-based lithography is improved by incorporating a sacrificial layer —...

Water pollution has becoming an increasingly serious issue, and it has attracted a significant amount of attention from scholars. Here, in order remove heavy metal hexavalent chromium (Cr (VI)) from wastewater, graphitic carbon nitride (g-C3N4) was modified with molybdenum disulfide (MoS2) at different mass ratios via an ultrasonic method to synthesize g-C3N4/MoS2 (CNM) nanocomposites as photocatalysts. The nanocomposites displayed efficient photocatalytic removal of toxic hexavalent chromium (Cr (VI)) from water under UV, solar, and visible light irradiation. The CNM composite with a 1:2 g-C3N4 to Mo...

Molybdenum cofactor deficiency in the neonate – expanding the phenotype
Molybdenum cofactor deficiency (MoCoD) is a rare metabolic disorder that affects the biosynthesis of the molybdenum cofactor, an essential cofactor for several enzymes including sulfite oxidase which leads to a buildup of toxic levels of sulfite. It can cause various neurological symptoms usually severe from the neonatal period, including intractable seizures and developmental delay [1][2]. (Source: Pediatric Neurology)

Electrochemiluminescence Enhancement and Passivation Mitigation in Carbon Nitride Semiconductors via an Integrated Ternary Heterostructure Strategy
In this study, the built-in electric field and the Schottky barrier effect is used to expedite the transfer of electrons from CN to the molybdenum disulfide (MoS2) conduction band. This transfer deterred excessive electron injection into the CN band, thus mitigating its electrochemical degradation. Moreover, by introducing nickel nanoparticles (Ni NPs) as catalytic active sites, it is facilitated that the decomposition of potassium persulfate (K2S2O8), thereby enhancing both the stability and intensity of ECL emission. In the end, the application of ternary heterostructure as sensing platform for the cancer biomarker carci...
