A major challenge to large-scale production and utilization of bacterial cellulose (BC) for various applications is its low yield and productivity by bacterial cells and the high cost of feedstock. A supplementation of the classical expensive Hestrin and Schramm (HS) medium with 1% polyethylene terephthalate ammonia hydrolysate (PETAH) resulted in as high as 215% yield. Although the physicochemical properties of BC were not significantly influenced, the BC produced in PETAH-supplemented HS medium showed a lower degree of crystallinity, and higher surface area, which showed 1.66 times higher adsorption capacity for tetracycline than BC produced in HS medium. The PETAH-supplemented HS medium respectively enhanced the activity of α-UDP-glucose pyrophosphorylase and α-phosphoglucomutase by 30.63% and 135.24% and decreased the activity of pyruvate kinase and phosphofructokinase by 40.34% and 52.63%. The results of this study provide insights into the activation mechanism of Taonella mepensis by PETAH supplementation for high productivity of BC. © 2022, The Authors. All rights reserved.

Here, we introduce a Terahertz (THz) dual-band coding reflective metasurface based on the Pancharatnam-Berry (PB) phase theory. The coding metasurface is consisted of a metal layer with hollow opening resonant ring on top of a double I-shaped deformation structure as the modified Polyimide (MPI) dielectric layer with a bottom reflective layer. It is capable of independent operation at two specific frequency bands of 0.33 THz and 0.51 THz. The high frequency double I-shaped deformation structure and the low frequency openwork resonant ring in the metal layer could be rotated and adjusted by PB phase theory to realize the continuous phase control from 0 to 2π. The coded cell at specific angles could construct coding arrays, achieving the modulation of wavefront. Due to the introduction of various encodings, the proposed metasurface enables to play a role as a vortex light generator at 0.33 THz, while it can act as a Radar Cross-section (RCS) reduction device to suppress the specular reflection of THz circularly polarized light at 0.51 THz. The simulated results show that the coding metasurface can work independently in low-frequency mode and high-frequency mode. In addition, the flexibility of the MPI layer indicates that the proposed metasurface has great potential for the integration of devices in the field of 6G communication and invisible coating. © 2025

Achieving non-centrosymmetric (NCS) configurations in ABX 3 -type hybrid halides remains a critical challenge for nonlinear optical (NLO) aterials due to the conflicting requirements of high second-harmonic generation (SHG) response, wide bandgap, and phase-matching capabilities. Herein, we propose a triple-site modulation strategy by synergistically tailoring the A -site cations (2-methylimidazole cation/1-ethyl-3-methylimidazole cation), B -site metals (Sn 2+ /Pb 2+ ), and X -site halogens (Cl/Br), which effectively disrupts lattice symmetry and enables NCS crystallization. Our results demonstrate a strong SHG response, an expanded optical bandgap and increased birefringence. The optimized compound C 6 H 11 N 2 PbCl 3 exhibits a record SHG efficiency of 3.8 × KDP, a wide bandgap (3.87 eV), and enhanced birefringence (0.14), surpassing majority hybrid NLO materials. The innovative anionic framework introduced here broadens the scope of hybrid NLO crystals, facilitating the integration of various aromatic heterocyclic cations. This research provides a robust strategy for the development of advanced NLO materials.

Lithium-oxygen (Li–O2) batteries have attracted significant attention in the field of energy storage owing to their high energy density, environmental benignity, and low cost. To make Li–O2 batteries practical, it is crucial to develop affordable and advanced cathodes with porous structures and high catalytic activity since the existing Li–O2 batteries are troubled by the insoluble and chemically stable lithium peroxide (Li2O2). Herein, Ru nanoclusters-modified hierarchical porous carbon (denoted RPC) is crafted from waste corn straw via a facile space-confined carbonization strategy. The natural fibrovascular structure of corn straw provides sufficient individual space for the accommodation of Li2O2. The ordered distribution of Ru nanoclusters with a controlled average size of ca. 4.3 nm induces uniform nucleation and growth of Li2O2. Benefiting from the synergy between the hierarchical structure and Ru catalyst, the Li–O2 battery exhibits remarkable electrochemical properties, including excellent specific capacity (13940 mAh g−1) and long cycle stability (over 214 cycles). Density functional theory (DFT) calculations reveal that the Ru nanoclusters facilitate the decomposition of Li2O2, leading to a lower overpotential. This versatile method provides a promising approach for reusing waste biomass in the construction of high-performance Li–O2 battery cathodes. © 2025 Elsevier Ltd

Oxygen evolution reaction is a momentous part of electrochemical energy storage and conversion devices such as rechargeable metal-air batteries. It is particularly urgent to develop low-cost and efficient electrocatalysts for oxygen evolution reactions. As a potential substitute for noble metal electrocatalysts, transition metal selenides are still challenging in improving the activity of oxygen evolution reaction and the research of reaction intermediates. In this study, a simple one-step solvothermal method was used to prepare a polymetallic compound carbon matrix composite (Co 9 Se 8 /Ni 3 Se 4 /Fe 3 O 4 @C) with a multilayered nanosheet structure. It exhibited good OER activity in an alkaline electrolyte solution with an overpotential of 252 mV at 10 mA/cm 2 and a Tafel slope of 123 mV/dec in an alkaline medium. Besides, this catalyst also showed excellent performance in the 8 hours stability test. The composite presents a multi-layer sheet structure, which effectively improves the contact between the active site and the electrolyte. The selenide formed by Ni and Co has a synergistic effect and improves the electrochemical performance together. The participation of Fe 3 O 4 reduces the bond energy of the intermediate oxygen evolution reaction. In addition, carbon quantum dots have rich heteroatoms and electron transferability, which improves the electrochemical properties of the composites. This work provides a new strategy for the preparation of highly efficient OER electrocatalysts utilizing the multimetal synergistic effect. © 2022, The Authors. All rights reserved.

Designing a highly active-and stable non-noble metal bifunctional oxygen catalyst for rechargeable Znair battery remains a great challenge. Herein, we develop a facile and melamine-assisted-pyrolysis(MAP)strategy for the synthesis of core–shell Co-based electrocatalysts@N-doped carbon nanotubes(Co@CNTs)derived from metal–organic frameworks. The Co@CNTs exhibited excellent bifunctional electrocatalytic performance for both oxygen evolution and reduction. DFT calculations demonstrated that the Gibbs free energy of the rate-determining step was small enough to improve ORR activities. As a result, a Zn-air battery assembled with Co@CNTs proves a lager power density, low voltage gap between charge–discharge and excellent stability. Thus, this work offers a facile strategy to realize the synthesis of non-noble metal electrocatalyst for Zn-air battery materials with high electrochemical performance.

To obtain synthetic leather with enhanced mechanical properties, we proposed a simple composite fabrication method based on nonsolvent induced phase separation for preparing polyurethane yarn(PUY) reinforced polyurethane(PU) composite films. The morphology of PU/PUY matrix interface and the mechanical properties of the as-prepared composite films were investigated in detail. The results showed that the addition of PUY did not change the microstructure of the PU. The stress and strain of PU/PUY-3 were 61.98% and 32.60% higher than that of PU film. It was proposed that the good interfacial interaction between PUY and PU mainly contributed to the simultaneously improvement in stress and strain. Furthermore, the as-prepared PU/PUY composite films were elastic within the applied tensile strain of 10%. The present work suggests an efficient way to reinforce PU matrix and can be used for design and optimization of leather products.

Herein, we report an unconventional heterobidentate coordination mode of conventional 4-hydroxypyridine ligand in a novel compound Zn(C 5 H 4 NO) 2 . The strong heterobidentate coordination interactions between Zn 2+ and 4-hydroxypyridine ligands promote a uniform alignment of the polarization of each [ZnO 2 N 2 ] tetrahedral building unit, resulting in remarkably strong second-harmonic generation (SHG) with an intensity that is the largest among all UV-transparent Zn-containing metal-organic compounds reaching 13.6×KDP. Moreover, Zn(C 5 H 4 NO) 2 processes a suitable optical band gap of 4.40 eV, high thermal stability up to 300 °C, excellent air stability, and strong water resistance, demonstrating great application potential. Additionally, Zn(C 5 H 4 NO) 2 exhibits photoluminescence with a significantly enhanced lifetime of 558 ms, accompanied by a rare blue afterglow visible to the naked eye, lasting up to 5 s.

Ru-modified NiO electrocatalysts for HER: Lower energy barriers and prolonged stability

引用

Chinese Chemical Letters 2025年

作者： Li Luo Xiaohong Cheng Qi Wu State Key Laboratory of New Textile Materials and Advanced Processing Technologies Wuhan Textile University Wuhan 430200 China College of Physical Science and Technology Central China Normal University Wuhan 430079 China Hubei Key Laboratory of Low Dimensional Optoelectronic Materials and Devices Hubei University of Arts and Science Xiangyang 441053 China

The hydrogen evolution reaction (HER) is a key process in electrocatalytic water splitting for hydrogen production, yet it is often limited by sluggish H*-OH adsorption and H* binding kinetics. We obtained Ru-modified NiO nanoparticles (Ru-NiO/NF) with enhanced HER properties by substituting Ruthenium (Ru) for Ni atoms in the NiO (200) crystalline facets on nickel foam by a one-step electrodeposition technique. This novel catalyst exhibits a significantly reduced *H-OH adsorption energy and improved kinetics, with an overpotential of only 60 mV at 10 mA/cm 2 and a Tafel slope of 26.19 mV/dec. The Ru-NiO/NF maintains its activity for over 115 h, outperforming NiO/NF by reducing the overpotential by 177 mV. DFT calculations confirm that the addition of Ru to NiO enhances the HER kinetics by modifying the electronic structure, optimizing the surface chemistry, stabilizing the intermediates, lowering the energy barriers, and facilitating efficient charge transfer through a robust three-dimensional structure, resulting in a change in the rate-limiting step and a significant reduction in the Gibbs free energy. This study presents a highly efficient HER catalyst and offers insights into designing advanced NiO-based electrocatalysts by reducing reaction energy barriers.
