Redox-active Co(II) and Zn(II) Pincer Complexes as High-Capacity Anode Materials for Lithium-Ion Batteries.

To address the ongoing demand for high-performance energy storage devices, it is crucial to identify new electrode materials. Lithium-ion batteries (LIBs) store energy via the electrochemical redox process, so their electrode materials should have reversible redox properties for rechargeability. On that note, redox-active metal complexes are explored as innovative electrode materials for LIBs.

Substrate-Mediated Growth of Au Nanowires Under Weak CTAB Control and Rapid Au Deposition.

The selective Au deposition at the Au-substrate interface is known to give ultrathin Au nanowires and the synthesis usually employs strong thiol-based ligands. It is shown that, by increasing the rate of Au deposition, weak cetyltrimethylammonium bromide (CTAB) can be made to behave like a strong ligand, so that it induces Active Surface Growth and gives Au nanowires. The ligand strength also depends on the packing interactions in the ligand layer, in the order of CTAB, CTAB, and CTAB.

Rat Models in Post-Traumatic Stress Disorder Research: Strengths, Limitations, and Implications for Translational Studies.

Post-Traumatic Stress Disorder (PTSD) is a multifaceted psychiatric disorder triggered by traumatic events, leading to prolonged psychological distress and varied symptoms. Rat models have been extensively used to explore the biological, behavioral, and neurochemical underpinnings of PTSD. This review critically examines the strengths and limitations of commonly used rat models, such as single prolonged stress (SPS), stress-re-stress (S-R), and predator-based paradigms, in replicating human PTSD pathology.

Toward Collective Chemistry under Strong Light-Matter Coupling.

Collective strong light-matter coupling provides a versatile means to manipulate physicochemical properties of molecules and materials. Understanding collective polaritonic dynamics is hindered by the macroscopic number of molecules interacting collectively with photonic modes. We develop a many-body theory to investigate the spectroscopy and dynamics of a molecular ensemble embedded in an optical cavity in the collective strong coupling regime.

Engineering Modular Peptide Nanoparticles for Ferroptosis-Enhanced Tumor Immunotherapy.

Indoleamine 2,3-dioxygenase 1 (IDO1) inhibitors are promising for treating tumors but have limited efficacy due to the immunosuppressive tumor microenvironment. In this study, we develop an orchestrated nanoparticle system using modular peptide assemblies, where the co-assembled sequences are designed for the specific binding to the hydrophobic and hydrophilic domains, guiding the assembly process and enabling the customization of nanoparticle properties. We exploit the modularity of this platform to integrate a hydrophobic ferroptosis precursor, an IDO1 inhibitor, and a hydrophilic peptidic PD-L1 antagonist for optimizing therapeutic outcomes through ferroptosis-enhanced tumor immunotherapy.

Facile preparation of sulfonium peptide and protein probes for selective crosslinking of methyllysine readers.

Sulfonium is an electrophilic and biocompatible group that is widely applied in synthetic chemistry on small molecules. However, there have been few developments of peptide or protein-based sulfonium tools. We recently reported sulfonium-mediated tryptophan crosslinking and developed NleSme2 (norleucine-dimethylsulfonium) peptides as dimethyllysine mimics that crosslink site-specific methyllysine readers.

Quantum Simulation of Partial Differential Equations via Schrödingerization.

We present a novel new way-called Schrödingerization-to simulate general (quantum and nonquantum) systems of linear ordinary and partial differential equations (PDEs) via quantum simulation. We introduce a new transform, referred to as the warped phase transformation, where any linear-including nonautonamous-system of ordinary or partial differential equation can be recast into a system of Schrödinger's equations, in real time, in a straightforward way. This approach is not only applicable to PDEs for classical problems but is also useful for quantum problems, including the preparation of quantum ground states and Gibbs thermal states, the simulation of quantum states in random media in the semiclassical limit, simulation of Schrödinger's equation in a bounded domain with artificial boundary conditions, and other non-Hermitian physics.

Crystal structures and photophysical properties of mono- and dinuclear Zn complexes flanked by tri-ethyl-ammonium.

Two new zinc(II) complexes, tri-ethyl-ammonium di-chlorido-[2-(4-nitro-phen-yl)-4-phenyl-quinolin-8-olato]zinc(II), (CHN){Zn(CHNO)Cl] (), and bis-(tri-ethyl-ammonium) {2,2'-[1,4-phenyl-enebis(nitrilo-methyl-idyne)]diphenolato}bis-[di-chlorido-zinc(II)], (CHN)[Zn(CHNO)Cl] (), were synthesized and their structures were determined using ESI-MS spectrometry, H NMR spectroscopy, and single-crystal X-ray diffraction. The results showed that the ligands 2-(4-nitro-phen-yl)-4-phenyl-quinolin-8-ol () and ,'-bis-(2-hy-droxy-benzyl-idene)benzene-1,4-di-amine () were deprotonated by tri-ethyl-amine, forming the counter-ion EtNH, which inter-acts an N-H⋯O hydrogen bond with the ligand. The Zn atoms have a distorted trigonal-pyramidal () and distorted tetra-hedral () geometries with a coord-ination number of four, coordinating with the ligands N and O atoms.

Safflower CtFT genes orchestrating flowering time and flavonoid biosynthesis.

Background: Safflower thrives in dry environments but faces difficulties with flowering in wet and rainy summers. Flavonoids play a role in flower development and can potentially alleviate these challenges. Furthermore, the FLOWERING LOCUS T (FT) family of phosphatidylethanolamine-binding protein (PEBP) genes play a crucial role in the photoperiodic flowering pathway.

Assembling Ancestors: the manipulation of Neolithic and Gallo-Roman skeletal remains from Pommerœul, Belgium.

The ancient cemetery of Pommerœul, Belgium, was classified as Gallo-Roman in the 1970s', yielding 76 cremation graves and one inhumation. However, subsequent radiocarbon analyses dated the inhumation to the Late Neolithic (4-3 millennium calBC). We report osteoarchaeological analysis indicating that the inhumation was composed of bones from multiple individuals, afterwards buried as "one".

Enhanced photocatalytic performance and a mechanistic study of novel black phosphorus/graphene/TiO composite membrane for o-chlorophenol removal.

The heterogeneous catalysis of the composite membrane not only exerts the synergistic effect of different materials but also enable the recyclable use of catalysts, making it an ideal and sustainable strategy for removing pollutants in water. In this study, a novel black phosphorus/graphene/titanium dioxide (BP/GR/TiO) membrane was successfully prepared through the sol-gel method. The composite membrane not only overcame the instability of black phosphorus and the rapid recombination of e/h pairs in titanium dioxide but also synergized with GR to produce a new reactive oxygen species (ROS), singlet oxygen (O), with a longer lifetime and migration distance.

Three-dimensional, multi-functionalized nanocellulose/alginate hydrogel for efficient and selective phosphate scavenging: Optimization, performance, and in-depth mechanisms.

Challenges in developing adsorbents with sufficient phosphate (P) adsorption capacity, selectivity, and regeneration properties remain to be addressed. Herein, a multi-functionalized high-capacity nanocellulose/alginate hydrogel (La-NCF/SA-PEI [La: lanthanum, NCF: nanocellulose fiber, SA: sodium alginate, PEI: polyethyleneimine]) was prepared through environmentally friendly methods. The La-NCF/SA-PEI hydrogel, featuring a 3D porous structure with interwoven functional groups (amino, quaternary ammonium, and lanthanum), demonstrated a maximum P adsorption capacity of 78.

Flow Matching for Optimal Reaction Coordinates of Biomolecular Systems.

We present flow matching for reaction coordinates (FMRC), a novel deep learning algorithm designed to identify optimal reaction coordinates (RC) in biomolecular reversible dynamics. FMRC is based on the mathematical principles of lumpability and decomposability, which we reformulate into a conditional probability framework for efficient data-driven optimization using deep generative models. While FMRC does not explicitly learn the well-established transfer operator or its eigenfunctions, it can effectively encode the dynamics of leading eigenfunctions of the system transfer operator into its low-dimensional RC space.

Future spinal reflex is embedded in primary motor cortex output.

Mammals can execute intended limb movements despite the fact that spinal reflexes involuntarily modulate muscle activity. To generate appropriate muscle activity, the cortical descending motor output must coordinate with spinal reflexes, yet the underlying neural mechanism remains unclear. We simultaneously recorded activities in motor-related cortical areas, afferent neurons, and forelimb muscles of monkeys performing reaching movements.

Methods: This study includes 70 patients (mean age ± standard deviation, 53.

Phytoliths in dicotyledons occurring in North-western Europe: Establishing a baseline.

Background And Aims: The absence of a modern plant-based 'dicotyledon' phytolith reference baseline impedes the accurate interpretation of fossil phytolith records in archaeological and palaeoecological research within North-western Europe. This study aims to fill this gap by documenting and analysing the phytolith record from modern dicotyledon taxa occurring in this region.

Methods: Phytoliths were extracted from several plant parts of 117 plant specimens representing 74 species (1-2 specimens/species).

Functional characteristics and mechanisms of microbial community succession and assembly in a long-term moving bed biofilm reactor treating real municipal wastewater.

Moving bed biofilm reactor (MBBR) technology with diverse merits is efficient in treating various waste streams whereas their microbial functional properties and ecology still need in-depth investigation, especially in real wastewater treatment systems. Herein, a well-controlled MBBR treating municipal wastewater was established to investigate the long-term system performance and the underlying principles of community succession and assembly. The system successfully achieved ammonium, TN, and chemical oxygen demand (COD) removal of 96.

Formation and Fate of Reactive Nitrogen during Biological Nitrogen Removal from Water: Important Yet Often Ignored Chemical Aspects of the Nitrogen Cycle.

Hydroxylamine, nitrous acid, and nitric oxide are obligate intermediates or side metabolites in different nitrogen-converting microorganisms. These compounds are unstable and susceptible to the formation of highly reactive nitrogen species, including nitrogen dioxide, dinitrogen trioxide, nitroxyl, and peroxynitrite. Due to the high reactivity and cytotoxicity, the buildup of reactive nitrogen can affect the interplay of microorganisms/microbial processes, stimulate the reactions with organic compounds like organic micropollutants (OMP) and act as the precursors of nitrous oxide (NO).
