Photocatalytic acceptorless dehydrogenation of flavanones by cationic Eosin Y as a bifunctional catalyst.

We report the first example of photocatalytic acceptorless dehydrogenation using cationic Eosin Y as a bifunctional photocatalyst, without metal catalysts or HAT reagents. Under Bayesian optimized conditions, a wide range of flavones were synthesized in moderate to excellent yields, many of which were reported with biological activities. Mechanistic studies suggest that flavones likely form through two HAT processes, with hydrogen release occurring photoredox.

Construction of an Sc-NiFe-LDH electrocatalyst for highly efficient electrooxidation of 5-hydroxymethylfurfural at industrial current density.

Renewable electricity-powered electrooxidation of 5-hydroxymethylfurfural (HMFOR) to FDCA offers a green and sustainable approach to producing an essential monomer for bio-polymers, provided that a highly efficient electrocatalyst is present. Herein, we show that the doping of scandium (Sc) into an NiFe-LDH electrocatalyst (Sc-NiFe-LDH) considerably promotes HMFOR by enhancing the formation of high-valence Ni-O active sites, facilitating electron transport and HMF adsorption and suppressing the oxygen evolution reaction. In the presence of the Sc-NiFe-LDH electrocatalyst, an FDCA faradaic efficiency and selectivity of 96.

Efficient recovery of valuable metals from electroplating sludge smelting soot via a combined alkali roasting and acid-free aluminum salts leaching methods.

Electroplating sludge smelting soot (ESSS), contains high-grade value metals (such as Zn, Sn, Pb, precious metals Au and Pt) and large amounts of harmful elements Br and S, which could potentially cause valuable resources wastage and environmental pollution, therefore requires responsible recycling. An efficient and eco-friendly process for the cascade recovery of Zn, Sn, Pb, and precious metals Au and Pt from ESSS was proposed, combining NaOH roasting and acid-free aluminum salts leaching. Optimal NaOH roasting conditions achieved high extraction efficiencies for Zn, Sn, and Pb, which were then separated via water leaching.

Hyperactivity of the IL-33-ILC2s-IL-13-M-MDSCs axis promotes cervical cancer progression.

The interleukin-33(IL-33) - group 2 innate lymphoid cells (ILC2s) - interleukin-13(IL-13) - monocytic myeloid-derived suppressor cells (M-MDSCs) axis plays a critical role in promoting immune evasion in tumors; however, its specific function in cervical cancer remains poorly understood. In this study, we observed that the proportion of IL-33-ILC2s-IL-13-M-MDSCs were significantly elevated in both cervical cancer patients and the subcutaneous U14 cervical cancer mouse model, compared to normal controls. Our results suggest that IL-33 stimulates ILC2s to secrete IL-13, which, in turn, regulates M-MDSCs to enhance their immune evasion capabilities.

Applying cross-scale regulations to Sedum plumbizincicola for strengthening the bioremediation of the agricultural soil that contaminated by electronic waste dismantling and revealing the underlying mechanisms by multi-omics.

Electronic waste dismantling has induced the surrounding agricultural soils suffered from combined contamination of heavy metals and organic pollutants. Lower efficiency and complex mechanisms of bioremediation remain to be resolved. Here, we adopted regulations to Sedum plumbizincicola cross aboveground and belowground scales to strengthen the bioremediation efficiency.

Metabolomic and transcriptomic analyses reveals candidate genes and pathways involved in secondary metabolism in Bergenia purpurascens.

Case report: targeted therapy of malignant pleural mesothelioma with anaplastic lymphoma kinase receptor tyrosine kinase gene fusion mutation by crizotinib.

Malignant mesothelioma is a rare highly invasive tumour originating from the mesothelial cells of the pleura, peritoneum and pericardium. Malignant pleural mesothelioma (MPM) is the most common type in all malignant mesothelioma. The onset of MPM is associated with exposure to asbestos and it can have an incubation period of up to 40 years.

Information spread behavior of clubhouse: A value-attitude-behavior model perspective.

The prevalence of social media has significantly facilitated the spread and diffusion of online memes. The Clubhouse voice community application, which gained popularity rapidly during the COVID-19 pandemic and became widely used, can be regarded as a form of internet meme. However, the underlying reasons for this phenomenon have been scarcely explored.

Long-range phase coherence and tunable second order -Josephson effect in a Dirac semimetal 1T-PtTe.

Superconducting diode effects have recently attracted much attention for their potential applications in superconducting logic circuits. Several pathways have been proposed to give rise to non-reciprocal critical currents in various superconductors and Josephson junctions. In this work, we establish the presence of a large Josephson diode effect in a type-II Dirac semimetal 1T-PtTe facilitated by its helical spin-momentum locking and distinguish it from extrinsic geometric effects.

Synergistically Improved Crystallinity and Molecular Doping Ability of Polythiophene-Diketopyrropyrrole Derivatives by -Trifluoromethylbenzene Containing Side Chains for Improved Thermoelectric Materials.

-Trifluoromethylbenzene (FB) groups have been widely employed in various fields; however, no studies have reported the use of FB in side chains to enhance the carrier mobility and molecular doping of conjugated polymers. In this study, based on density functional theory (DFT) calculations, we discovered that FB groups can effectively bind to [FeCl], the counterion of the p-type dopant FeCl, thereby increasing doping ability. Consequently, FB groups were incorporated into the side chains of thiophene-diketopyrrolopyrrole-based donor-acceptor (D-A)-conjugated polymers, and a series of random conjugated polymers were synthesized (denoted as PDPPFB-, where represents the molar ratio of the FB side chain).
