Summary: This study demonstrates the feasibility of continuously modulating ESIPT dynamics in HPO derivatives by investigating electron population variations on proton donor and acceptor. An index Δpdif was proposed to evaluate the overall promotion effect on proton transfer, showing high reliability in interpreting the ESIPT tendency. This method has great potential in ESIPT molecular design with chemical substitution of electron-donating/withdrawing moieties.

Summary: Investigating aqueous CO2 reduction on catalysts with redox-noninnocent ligands is essential as they promote CO2 reduction while avoiding H2 evolution. By using rapid-scan FT-IR in external reflection mode, the researchers monitored the pathway of CO2 reduction on iron porphyrin in real-time. They discovered that the protonation of the porphyrin nitrogen, coupled with first-electron reduction of [Fe(II)TAPP](0), avoids the formation of Fe-H structure, and the protonated porphyrin-N acts as a proton relay for efficient inner-sphere proton transfer to activated CO2 molecules. This study provides experimental evidence of proton migration pathway via reduced porphyrin ligands and has implications for the design of catalysts with high CO2 reduction selectivity.

Summary: The development of highly efficient sensing systems for trace organic contaminants requires the understanding and application of excited-state inter-ligand proton transfer (ESILPT) processes. Utilizing strategically synthesized lanthanide complexes with excellent photophysical properties, a feasible pathway to construct efficient chemo-sensors for ultra-sensitive detection of nitrofuran antibiotics has been demonstrated. This advancement is expected to broaden and deepen research in complex-based luminophores, potentially useful in trace detection and biological imaging.

Summary: The study investigates five novel heteroleptic Cu(I) complexes with monodentate triphenylphosphine co-ligands, which are more stable than their homoleptic bis(4H-imidazolato)Cu(I) congeners due to the anionic 4H-imidazolate ligand. The ligand exchange reactivity, ground state structural and electronic properties, and excited-state dynamics of the complexes are studied using various techniques. The increased geometric flexibility of the triphenylphosphines in comparison to chelating bisphosphine ligands makes these complexes interesting candidates for studying photo(redox)reactions.

Summary: In this study, the ESDPT process in the ligand was investigated using theoretical methods. It was found that the asymmetric structure influences proton transfer, resulting in different transfer abilities for the two hydrogen protons. The potential energy surface analysis revealed that HYDRAVH(2) can undergo ESDPT in the S-1 state through a stepwise proton transfer mechanism.

Summary: The repeated failures of amyloid-targeting therapies have led to a reevaluation of Alzheimer's disease pathogenesis, revealing a complex web of biochemical and cellular processes beyond amyloid accumulation. Network-based proteomics has emerged as a powerful tool to explore the underlying protein pathophysiology of AD, and may lead to the discovery of novel protein biomarkers of the disease.

Summary: This study compared the interactomes of three FUS variants using mass spectrometry and found that the phosphomimetic FUS interactome is enriched for cytoplasmic proteins involved in mRNA metabolism and translation, as well as nuclear proteins involved in the spliceosome and DNA repair functions. Additionally, the RNA-induced silencing complex RNA helicase MOV10 was identified as a novel interacting partner of FUS. Functional evidence suggests that N-terminally phosphorylated FUS may disrupt homeostatic translation and steady-state levels of specific mRNA transcripts.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing.

Summary: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.

Summary: Developing low-cost and self-supported bifunctional catalysts is crucial for highly efficient water splitting devices. In this study, nano-NiFe2O4 was directly grown onto iron foil surface and Sn4+ was introduced into the NiFe2O4. The resulting Sn-NiFe2O4/IF showed low overpotentials and high current densities during oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), making it a promising catalyst for large-scale hydrogen production.
