Photocatalytic C−N coupling offers a promising approach for the sustainable production of amino acids, but the uncontrolled coupling pathway of reaction intermediates limits yield and selectivity. This paper describes a Pd−B diatomic catalyst that can selectively catalyze the photosynthesis of glycine via C−N coupling reaction between waste poly(ethylene terephthalate)-derived ethylene glycol and nitrate, achieving a glycine yield of 2.9 mmol g cat −1 h −1 with a selectivity of 92%. Mechanistic investigations reveal that ethylene glycol is photo-oxidized to glycolaldehyde at the hole-rich B site, while nitrate is photo-reduced to NH 4 + /NH 3 at the electron-rich Pd site. Subsequently, glycolaldehyde undergoes C−N coupling with NH 4 + /NH 3 , and further photo-oxidized to form glycine. The Pd−B diatomic site more effectively stabilizes the glycolaldehyde intermediate, resulting in a more favorable C−N coupling pathway than metal oxide and enhancing glycine selectivity. Thus, we show a catalytic system for selective glycine photosynthesis by precisely regulating the reaction pathways of key intermediates.

Charge transfer across interfaces constitutes the rate-determining step in electrochemical systems. Sluggish kinetics triggers side reactions and hazardous surface morphologies, as represented by dendritic/dead lithium (Li 0 ) in Li-metal batteries (LMBs), especially under ultrafast charging (UFC). Here we report an approach to accelerate interfacial charge transfer by redesigning the solvent molecular structure into a distinctive planar coordination of lone-pair electrons (LPEs) with alkaline cations (Li + or Na + ). This planar-aligned electron channel (PAEC) greatly strengthens the coupling between LPEs and Li + , promoting Li + /Li 0 redox reaction kinetics and reversibility. The designed electrolyte dramatically enables stable cycling of industrial 2 Ah Li||LiNi 0.8 Mn 0.1 Co 0.1 O 2 pouch cells at an ultrahigh rate of 4 C, achieving 100% full charge within 15 min at a charging power density of 1,747.6 W kg −1 . We establish a link between the solvation electronic structure and charge-transfer dynamics, highlighting a potential strategy for electrolyte design under extreme electrochemical conditions.

Antimicrobial peptide BmKn2-7, a rationally optimized derivative of the scorpion venom peptide BmKn2, shows strong potential as an antibiotic alternative for controlling Vibrio parahaemolyticus in aquaculture. This study evaluated its antibacterial mechanisms and in vivo efficacy in Litopenaeus vannamei through biochemical assays, transcriptomic profiling, and challenge experiments. BmKn2-7 exhibited potent in-vitro activity (MIC = 125 µg/mL) and disrupted bacterial homeostasis by increasing membrane permeability, inducing oxidative stress, and inhibiting P-type ATPase. RNA-seq analysis revealed extensive transcriptional reprogramming, including the downregulation of quorum-sensing, virulence, and β-lactam resistance–associated genes. In vivo, BmKn2-7 significantly improved shrimp survival following V. parahaemolyticus infection and selectively reduced Vibrio abundance in the gut without compromising overall microbiota diversity. Together, these findings demonstrate that BmKn2-7 acts through complementary bactericidal and anti-virulence pathways while promoting intestinal microbial resilience, supporting its potential as a promising antimicrobial candidate for reducing vibriosis risk in shrimp aquaculture.

The proton-coupled electron transfer (PCET) kinetics plays a critical role in governing the CO 2 -to-formate conversion efficiency during CO 2 eletroreduction reaction. While alkali metal cations are known to influence the reaction pathway, elucidating how trace doping modifies the catalytic sites remains a key challenge. Here we show that incorporating Li into bismuth oxycarbonate (BOC-Li) induces structural modifications that optimize the PCET process at bismuth-active sites, thereby boosting CO 2 -to-formate conversion. By employing dual-isotope ( 2 H/ 13 C) operando nuclear magnetic resonance (NMR) to track the formation of 1 H 13 COO − / 2 H 13 COO − , combined with kinetic isotope effect, Tafel analysis and in situ attenuated total reflection surface-enhanced infrared absorption spectroscopy, we observe a more efficient proton-electron transfer pathway. Density functional theory (DFT) calculations suggest that Li doping is associated with enhanced activity of Bi sites, potentially strengthening H 2 O/CO 2 adsorption and reducing the O–H activation energy. Collectively, this work highlights alkali doping as a promising strategy for structurally engineering catalytic sites to improve PCET kinetics.

Background Polydopamine nanoparticles (PDA NPs) hold considerable significance in biomedical field due to their diverse multifunctionality, including efficient metal ion chelation, intrinsic antioxidant activity, and robust photothermal properties. Especially, ultrasmall PDA NPs can evade rapid liver and spleen accumulation, enabling multi-organ distribution and wide biological applications. However, current methods for synthesizing ultrasmall PDA NPs face the bottleneck of complex synthesis processes. Methods We showed an alkali-controlled one-pot synthesis of ultrasmall PEGylated PDA (UPPDA) NPs. Upon Mn 2+ chelation, the resulting PDA-PEG-Mn (PPMn) NPs were employed for contrast-enhanced magnetic resonance imaging (MRI) in multiple systemic diseases, including glioma (a nervous system disease), carotid artery stenosis (a circulatory system disease), and acute kidney injury (a urinary system disease). Furthermore, UPPDA NPs were utilized for antioxidant treatment and photothermal therapy at the cellular level. Results PPMn NPs enable precise diagnosis of glioma, carotid artery stenosis, and acute kidney injury through MRI. Additionally, UPPDA and PPMn NPs exhibit outstanding antioxidant properties and demonstrate effective photothermal ablation capabilities at the cellular level. Conclusions The proposed UPPDA NPs provide a universal platform for the diagnosis and treatment of various diseases. Graphical abstract

In this study, to mitigate the ecological risks associated with ofloxacin residues in the environment, two drug-resistant strains, Aerococcus sp. DORC01 and Aspergillus sp. DYN01, were isolated and acclimatized from chronically exposed cow dung. Their efficacy in removing ofloxacin was optimized using both single-organism and mixed-co-culture systems, in conjunction with response surface methodology. Under optimal conditions for single-organism systems, DORC01 and DYN01 achieved 68.7% and 51.8% removal of 100 mg/L ofloxacin over a 7-day period, respectively. The optimal conditions for DORC01 were 29.61 °C, 70.05 mg/L substrate concentration, and 0.46% bacterial load, while for DYN01, they were pH 5.97, 72.99 mg/L substrate concentration, and 0.50% bacterial load. The mixed mycelium spheres were further prepared using a co-culture method with a 3:1 ratio, resulting in an enhanced predicted maximum removal rate of 93.91% under conditions of 33.50 °C, pH 7.45, 0.37% bacterial volume, and a substrate concentration of 74.96 mg/L. This represents a 45% improvement over the efficiency observed with single bacterial cultures. Inactivation experiments demonstrated that live bacteria facilitated degradation primarily through biosorption, with degradation being the dominant process. After 7 days, the removal rate achieved by live bacteria was significantly higher than that of inactivated bacteria. This study is the first to establish a synergistic system involving Aerococcus and Aspergillus, offering a novel strategy for the efficient bioremediation of antibiotic contamination in livestock and poultry environments.

Recent breakthroughs in three-dimensional (3D) printing of glass have enabled precise shaping of glass structures from macro to microscale while retaining their excellent physical and chemical properties. However, current functional developments in 3D printed glass primarily focus on leveraging its intrinsic optical transparency, with limited exploration of photonics application. 3D-printed glass functionalized by quantum dots (QDs) will hold great promise for creating desired photonic functional macro- and microstructures. However, voxel-precision customization of photonic functions in 3D printed glass by the monodispersed and size-controlled QDs is fundamentally conflict with the high-temperature sintering process required in 3D printed glass. Here, we present a simple, cost-effective method for creating a library of QDs functionalized 3D-printed glasses with tunable UV-VIS-IR photoluminescence (PL) by printing nanoporous glass (NG) followed by low-temperature nanoscale engineering of QDs growth. The integration of uniform and size-controlled QDs imparts 3D printed glass with fine tuning in composition, architecture, and photonic functionalities, while nanoscale engineering of the micro-environment enables precise tailoring of various QDs with enhanced optical performance and stability. This universal approach establishes a benchmark for 3D-printed functional glasses with advanced photonic capabilities.

In this study, a dual-ratiometric optical probe utilizing europium-doped carbon dots (Eu-CDs) was developed for simultaneous fluorescent and colorimetric detection of tetracycline (TC). The Eu-CDs complex was synthesized through a hydrothermal approach. Upon coordination with Eriochrome Black T (EBT), the Eu-CDs complex exhibits a distinct magenta coloration. Introduction of TC triggers a ligand displacement reaction, resulting in color transition from magenta to blue, resulting in ratiometric colorimetric visual detection. Meanwhile, the TC-bound EBT-CDs@Eu complex emits ratiometric fluorescence change. A ratiometric fluorescence detection method was established for TC based on the absorbance-energy transfer-emission (AETE) mechanism, culminating in the successful design of a dual-ratiometric optical probe. The colorimetric assay demonstrated a detection limit (LOD) of 20.5 nM for TC. Furthermore, the practical applicability of this sensor was validated through successful TC detection in aquaculture samples, highlighting its potential for real-world monitoring applications.

Hybrid lead halides have demonstrated great promise for CO 2 photoreduction due to their excellent photophysical properties. However, developing a single-component hybrid lead halide that combines high intrinsic stability with near-infrared absorption remains a significant challenge. Herein, to address both issues, we design a series of nine highly stable lead halide frameworks functionalized by bis(terpyridine)-metal complexes, which exhibit strong light absorption extending into the near-infrared region up to 1150 nm. Unlike their symmetric chloride and bromide analogues, the charge-polarized lead iodide sites in bis(terpyridine)-metal-functionalized frameworks serve as highly efficient C–C coupling centers for C 2 production in near-infrared-driven CO 2 photoreduction, achieving notable C 2 production rates of up to 14.2 μ mol g -1 h -1 with electron selectivities as high as 86%. These performances match the state-of-the-art among all reported single-component, near-infrared-responsive photocatalysts. This work highlights the potential of coordination-driven assembly of highly stable lead halide frameworks for near-infrared-driven artificial photosynthesis.

The formation of silver nanoparticles (AgNPs) as byproducts during the synthesis of silver nanowires (AgNWs) necessitates accurate quantification of their relative abundances for evaluating practical applications. This study introduces a rapid quantitative approach based on UV-Vis spectral peak deconvolution. By modulating the molecular weight (MW) of polyvinylpyrrolidone (PVP), effective control over the diameter and yield of AgNWs was realized. Experimental results show that low-MW PVP (24 kDa) promotes the formation of short nanorods, intermediate-MW PVP (220 kDa) maximizes the aspect ratio to 370, and high-MW PVP (1300 kDa) reduces it to 310 due to steric hindrance. A novel mixed PVP system (1300 kDa:24 kDa = 2:1) significantly optimizes the nanowire morphology, yielding AgNWs with an aspect ratio of 920. However, competitive adsorption kinetics in this system resulted in a minimum AgNW/AgNP ratio of 0.90. A quantitative model correlating the average diameter of AgNWs with their characteristic UV-Vis absorption peak (370–400 nm) was established, enabling rapid diameter estimation through spectral analysis. Gaussian-Lorentzian hybrid functions were used to deconvolute the plasmon resonance peaks of AgNWs (370–400 nm) and AgNPs (450–500 nm), with the ratio of their peak areas employed to determine the proportion of wire-like products. This method shows strong agreement with SEM statistical results (Pearson coefficient = 0.84, R 2 = 0.75). Without requiring complex separation or machine learning, our approach enables rapid determination of AgNW diameters and yields through UV-Vis spectral deconvolution, providing an efficient and cost-effective solution for optimizing industrial synthesis and quality control.

CdTe nanoparticle-sensitized TiO 2 nanotube arrays (CdTe/TiO 2 NTAs) were prepared by combining the sol–gel method with the electrodeposition method by the aid of anodic aluminum oxide template. The morphology, structure and composition of the materials were characterized by scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray spectroscopy and X-ray diffraction (XRD). The photo response and photocatalytic activity of the materials were investigated by UV–Vis absorption spectroscopy. The results show that the pore diameter of the TiO 2 nanotubes is about 120 nm and the wall thickness is approximately 30 nm. CdTe nanoparticles are deposited both inside and in the tube-to-tube voids of the TiO 2 nanotubes. XRD analyses identify the anatase structure of TiO 2 nanotubes and cubic sphalerite structure of CdTe. Compared with pure TiO 2 nanotube film, the CdTe/TiO 2 NTAs display a significant increase in absorption coefficient in the visible light and a higher activity for photodegrading Rhodamine B under Xe lamp irradiation with an increase from 34 to 88%. The results also show that CdTe/TiO 2 NTAs exhibit better photoelectrochemical performance than TiO 2 NTAs.

Phosphorus-doped ZnSe nanowires were synthesized by using phosphorus (P) as dopant via thermal evaporation method. Their doping effect and obvious p-type conduction were confirmed through a top-gate MISFET based on individual P-doped ZnSeNW. Negative photoconductivity (the photocurrent was lower than the dark current) was found in p-type ZnSeNWs due to their surface effect. Two terminal devices based on p-type ZnSeNWs, as gas sensors, were also constructed and performed effective detecting behaviors to oxidizing gas. Furthermore, a complementary photodetector containing both n-type ZnSeNWs and p-type ZnSeNWs was first manufactured to eliminate the effects of crosstalk or false signal exist in conventional photodetectors. These results are expected to be used to develop new-type nano-devices and expand their applications.
