Summary: The lack of direct proof for trans-dinitrosyl hemes in heme proteins has hindered understanding of the reaction mechanisms with nitric oxide. This study reports the isolation of a dinitrosyl metalloporphyrin complex, providing insight into the reaction processes and demonstrating different responses of porphyrinates to nitric oxide.

Summary: This study proposes a method to synthesize a Mn2+- coordinated polymer precursor ligated by sulfur atoms with acetate counter ions. MnS/MnO decorated N, S-doped carbon nanoparticles are prepared by calcination of the Mn ion-coordinated polymer for the practical applications of catalytic reactions. The performance of the nanoparticles in catalytic oxidation reactions is mainly related to the MnO decorated outside the SNC particles compared to MnS formed inside the particles.

Summary: By optimizing electrodeposition parameters and calcination temperature, manganese oxide-coated TiO2 nanotube arrays were synthesized for efficient and selective oxidation of sulfide to elemental sulfur. The inner sphere complex between sulfide ion and Mn-oxide facilitated rapid electrocatalytic re-oxidation of the Mn-oxide coating, resulting in the production of colloidal sulfur as the final product of sulfide oxidation. The stable (electro) catalytic activity of the Ti/TiO2 NTA/Mn oxide anode in both synthetic electrolyte and real sewage demonstrated its effectiveness for sulfide oxidation in complex waste streams.

Summary: The synthesis and characterization of a new Cu(II) complex with a bidentate Schiff base were reported. The structure of CuL2 was determined using single crystal X-ray diffraction, revealing a square planar geometry with two naphthyl substituents perpendicular to the molecular plane. Additional analysis was conducted using IR and UV-Visible spectroscopy techniques. The catalytic activity of CuL2 in the oxidation of primary and secondary alcohols was investigated, with TBHP and imidazole identified as an effective oxidant/additive combination.

Summary: MnxOy coated TiO2 nanotube array substrate doped with Mo and PANI exhibited excellent activity and stability for electrochemical desulfurization in basic pH conditions. The introduction of Mo and PANI co-dopants increased the electrochemically active surface area, improved coating conductivity, and reduced charge transfer resistance. The catalytic oxidation of sulfide showed minimal impact from different operational parameters, and long-term anode usage requires periodic removal of the formed sulfur layer.

Summary: Stable chromium isotopes have been used as a paleoredox proxy to track atmospheric oxygenation, with previous belief that Cr oxidation is limited to terrestrial settings. However, recent research shows rapid marine Cr(III) oxidation linked to microbial Mn(II) oxidation, challenging the traditional view. Initial partial oxidation of Cr(III) to Cr(VI) can cause a small isotope fractionation, calling for a reevaluation of the link between Cr isotope values and atmospheric oxygenation.

Summary: Recent studies have shown that metal-sulfur coordination compounds can regulate reactive sulfur species (RSS) transport. The reaction of B-Ph-((t)BuIm)(3)NiCl with RSS leads to the formation of square planar complexes through protonation of a carbene ligand donor atom. Mechanistic investigation suggest that protonation may occur from the decomposition of reactants, interactions with favorable counterions, or generation of transient unidentified RSS.

Summary: This study investigated the oxidative removal of Mn(II) by peroxymonosulfate (PMS). It was found that PMS is a more efficient oxidant than chlorine for Mn(II) oxidation. The oxidation of Mn(II) by PMS consists of both homogeneous and heterogeneous processes. Complexion with ligands and coexisting metal ions can greatly affect the oxidation rate and mechanism of Mn(II). The results highlight that PMS oxidation is an attractive alternative technology for Mn(II) removal and provide a fundamental understanding of Mn materials-based advanced oxidation processes.

Summary: In this study, two new quadripartite nanocomposites were synthesized, consisting of conductive polymer, expanded and functionalized graphene sheets, and magnetic parts. The contiguity of magnetic oxide, conductive polymer, and rare earth metal oxide was investigated. The compounds were characterized using FTIR, XRD, FE-SEM, and EDX, and their electrochemical and magnetic properties were analyzed. The results showed that the use of cerium oxide instead of terbium oxide reduced the magnetic property and increased the current density.

Summary: This study examined the preferences of health providers for policy interventions to address informal payments in Tanzania using a discrete choice experiment. The results showed that health providers generally preferred incentive payments for non-infraction and opportunities for private practice, but disliked disciplinary measures. Preferences varied across different groups, suggesting the need for tailored interventions.

Meeting the 85% adult population target can partially offset the costs of vaccine programs by increasing consumption tax revenues.

Summary: Children around the world are exposed to extensive marketing for gambling products, which normalizes gambling as harmless entertainment despite evidence of its harms. Regulatory efforts to protect children from gambling marketing are inconsistent and inadequate. A comprehensive public health approach is urgently needed to limit the influence of gambling marketing on young people.

Summary: Recognising the lack of preparedness for the COVID-19 pandemic, international organisations are calling for additional funding to strengthen pandemic preparedness and response systems in low-income and middle-income countries. This article examines the prospects of national health budgets increasing in such a context, revealing that public spending will decrease for almost half of these countries by 2024. The increase in public spending on repaying external debt is a key driver of this austerity wave, potentially leading to deteriorating population health and reduced public health services.

Summary: An unprecedented mortality crisis occurred in Eastern Europe during the 1990s, resulting in around seven million excess deaths. This study examines the relationship between deindustrialization and mortality in Eastern Europe and proposes a theoretical framework that identifies deindustrialization as a process of social disintegration caused by shock therapy. The findings show that deindustrialization directly influenced male mortality rates and was indirectly mediated by hazardous drinking as a coping strategy.

Summary: A novel thin-film nanocomposite (TFN) membrane modified by MoS2@Zeolite X nanocomposite was used for desalination by the forward osmosis (FO) method. The incorporation of MoS2@Zeolite X nanocomposite particles into the polyamide selective layer of the TFN membrane improved its desalination performance and antifouling properties. The TFN-MZ(2) membrane, containing 0.01wt% MoS2@Zeolite X, showed the highest water flux and antifouling tendency among the membranes tested.

Summary: A newly isolated binuclear nickel(II) complex, [Ni-2(en)(4)(ox)](ClO4)(2), has been determined to have a crystal structure using X-ray crystallography and infra-red techniques. This complex was successfully used as a catalyst for the one-pot reaction of aldehydes, amines, and acetylenes, resulting in the construction of propargylamines with high yields under solvent-free conditions. Further studies showed that this catalytic system could be reused for five runs.
