The recycling of waste cathode ray tube (CRT) glass in cement-based materials is hindered by its low early age reactivity which limits mechanical performance and large-scale utilization. This study presents a novel strategy to overcome this limitation by incorporating C-S-H seedings into waste CRT glass-Portland cement (PC) systems. Through a multi scale investigation encompassing workability compressive strength hydration kinetics phase assemblage and pore structure we demonstrate that C-S-H seedings act as both nucleation sites and physical fillers significantly accelerating early age hydration and promoting later pozzolanic reactions. An optimal seeding content of 1.5 wt enhanced 1 d compressive strength by 50.0% compared to the control and even surpassed pure PC by 40.5%. Notably total porosity was reduced by up to 63.2% at 1 d and the critical pore diameter was substantially refined. These improvements are attributed to a dual stage mechanism involving early age nucleation seeding and pore filling followed by enhanced pozzolanic reaction of waste glass at later ages. This work provides a scalable and effective approach for valorizing waste CRT glass in sustainable cementitious materials with a carbon emission reduction of 11.17% compared to conventional PC. The findings also highlight the need for future research on long term durability and life cycle assessment to support practical deployment.

Lignin is an ideal precursor for developing efficient, green, and low-cost carbon dot corrosion inhibitors because it is one of the most abundant sustainable resources. Nevertheless, its potential in this field has not yet been fully exploited. In this paper, a novel type of N, S-doped lignin-based carbon dots (N, S-LCDs) with ultra-high inhibition performance was successfully prepared, using lignin as a precursor and 2-thiazoline-2-thiol as both the nitrogen and sulfur source. It was demonstrated that the N, S-LCDs maintained a high corrosion inhibition efficiency of nearly 90% within the temperature range of 20 to 50 °C, with the maximum efficiency of 97.24% observed at 30 °C. Furthermore, a prolonged immersion test over 72 h confirmed the excellent stability of N, S-LCDs. Characterization results indicated that the synergistic co-doping of N and S is the key to N, S-LCDs superior performance. The adsorption of N, S-LCDs on the cold rolled steel (CRS) surface conforms to the Langmuir adsorption isotherm, and a protective film is formed on the CRS surface through physical and chemical adsorption, thereby effectively inhibiting the corrosion process.

en The dual challenges of environmental sustainability and rising energy needs underscore the necessity for high-energy-density batteries, making lithium–sulfur (LSB) systems with their high theoretical capacity highly attractive. However, the polysulfide shuttle, coupled with inherent kinetic limitations in the sulfur reduction reaction, significantly compromises the battery's commercialization. Utilizing biomass-derived materials presents a sustainable and cost-effective approach to mitigating these issues. Therefore, in this study, a series of cobalt–nitrogen co-doped porous carbon materials (Co,N-C) were prepared from ramie waste glue by adjusting the cobalt source content, and their electrochemical properties as sulfur hosts were systematically investigated. Among them, Co,N-C-2 exhibits the best performance. The three-dimensional (3D) porous architecture promotes electrolyte penetration and lithium–ion mobility, whereas the Co,N co-doping sites effectively adsorb lithium polysulfides, markedly reducing the shuttle effect and improving conversion kinetics. The Co,N-C-2/S cathode has an initial discharge capacity of 1274.2 mAh g −1 at 0.2C and sustains a reversible capacity of 540.6 mAh g −1 after 350 cycles at 1C, demonstrating a minimal degradation rate of 0.11% each cycle. This study offers a sustainable and cost-effective design strategy for high-performance LSBs. 摘要 zh 环境可持续性和不断增长的能源需求所带来的双重挑战凸显了高能量密度电池的必要性,这使得具有高理论容量的锂硫(LSB)电池系统极具吸引力。然而,多硫化物穿梭效应以及硫还原反应固有的动力学限制严重阻碍了该电池的商业化进程。利用生物质衍生材料为解决这些问题提供了一种可持续且经济有效的途径。因此,在本研究中,通过调整钴源含量,以苎麻废胶为原料制备了一系列钴氮共掺杂多孔碳材料(Co,N–C),并对其作为硫宿主的电化学性能进行了系统研究。其中,Co,N-C-2 表现最佳。三维(3D)多孔结构促进了电解质的渗透和锂离子的迁移,而钴氮共掺杂位点能有效吸附多硫化锂,显著减少了穿梭效应并改善了转化动力学。Co,N-C-2/S 正极在 0.2C 时的初始放电容量为 1274.2 mAh g −1 ,在 1C 下经过 350 次循环后仍能保持 540.6 mAh g −1 的可逆容量,每循环的容量衰减率仅为 0.11%。这项研究为高性能锂硫电池提供了一种可持续且经济的设计策略。

A ratiometric enzymatic fluorescence biosensor for OP detection was developed. • Recombinant carboxylesterase PvCarE1 enhances stability and reproducibility over conventional AChE. • Dual-excitation N,S-CQDs enable self-calibrated and robust signal output. • Satisfactory recoveries (82.0%–109.9%) in eight food matrices. • Results agreed well with LC-MS/MS, supporting practical food analysis. The widespread use of organophosphorus pesticides (OPs) poses significant threats to food safety and environmental health, necessitating the development of robust and sensitive detection platforms. We present a novel ratiometric biosensor based on a recombinant carboxylesterase (PvCarE1) integrated with dual-excitation nitrogen and sulfur co-doped carbon quantum dots (N,S-CQDs). The sensing mechanism relies on an inner filter effect (IFE), where the enzymatic hydrolysis product ( p -nitrophenol) selectively quenches 370 nm-excited fluorescence, while 255 nm-excited emission remains less affected. OP inhibition reduces p -nitrophenol generation, yielding a dose-dependent F₃₇₀/F₂₅₅ response that provides intrinsic self-calibration. The biosensor exhibited high sensitivity for dichlorvos, trichlorfon, and profenofos with detection limits of 0.07, 0.38, and 0.45 μg/L, respectively. Successful application in eight representative fruit and vegetable samples yielded satisfactory recoveries of 82.0%–109.9% with RSDs of 0.4%–11.9%, confirming its potential for real-world food safety monitoring.

Sulfides-based all-solid-state lithium batteries show great potential due to their high safety and high energy density, yet severely suffer from sulfide electrolytes/Li interfacial instability and short cycle life. Here we propose a Li-In-S composite foil comprising Li 2 S, Li x In, and LiInS 2 to stabilize the Li/Li 6 PS 5 Cl interface by constructing built-in electric fields, thereby enabling long-life all-solid-state lithium batteries. The work function difference between Li 2 S and Li x In generates built-in electric fields at the heterointerface, which traps the interfacial electrons and restricts their transfer to Li 6 PS 5 Cl, thereby suppressing the interfacial side reactions. Simultaneously, the built-in electric fields promote Li + adsorption and diffusion inhibiting lithium dendrite growth. Li symmetrical cells display high critical current density over 4 mA cm −2 and Li plating/stripping stability over 2000 h at 1 mA cm −2 . The assembled full cells with LiCoO 2 and LiNi 0.8 Co 0.1 Mn 0.1 (NCM811) demonstrate high capacity retention of 93% over 2000 cycles at 1 C and 87.7% over 1000 cycles at 1 C, respectively. Moreover, Li-In-S|Li 6 PS 5 Cl|NCM811 full cell shows rate capability up to 4 C. This work offers useful insights into the design of stable interfaces in all-solid-state batteries.

Designing intelligent anticorrosion systems that couple
robust
protection with real-time corrosion visualization remains a formidable
challenge in industrial safety and infrastructure longevity. Here,
a one-step hydrothermal condensation of 2-aminothiazole and citric
acid yields a multifunctional carbon dot (CD) whose surface is densely
terminated with N-, O-, and S-bearing functionalities. These heteroatom-rich
groups furnish abundant coordination anchors for metal substrates.
Electrochemical assays and gravimetric measurements reveal that the
CD delivers a corrosion inhibition efficiency of 95.18% for N80 steel
in 1 M HCl at a dosage of 200 mg/L. Adsorption conforms to the Langmuir
isotherm with a Gibbs free energy of −31.66 kJ/mol, indicating
a spontaneous mixed physical-chemical adsorption mechanism dominated
by chemisorptive interactions from Fe–N, C–S, and S═O
linkages. Surface analyses confirm a compact, adherent protective
film that strongly retards both anodic dissolution and cathodic hydrogen
evolution. Capitalizing on the intrinsic blue fluorescence of the
CD, the system additionally accomplishes in situ reporting of corrosion
progression: fluorescence quenching occurs synchronously with Fe 3+ /Fe 2+ release as the film degrades. This work
establishes a single-component “protect-and-report”
platform, offering an effective and conceptually innovative strategy
for next-generation corrosion management.

Sucrose-derived carbon spheres are promising host materials for cathode sulfur species in Room-Temperature (RT) Na-S batteries. Therefore, the morphology, micro-mesoporous structure, and oxygen-containing functional groups of sucrose-derived nanocarbon spheres were regulated to effectively accommodate sulfur species. This structural design facilitates sulfur confinement, improves charge/ion transport, and enhances the cycling stability of AC@S composites. With increasing activation temperature, the developed porous structure provides more storage sites for active sulfur species; however, excessive activation can reduce the content of oxygen- containing functional groups and weaken the chemical anchoring capability of the carbon framework. Among the prepared samples, AC@S-900 delivered the highest initial capacity of 1323.35 mAh g -1 at 1.0 C, whereas AC@S-750 exhibited superior cycling durability, delivering an initial specific capacity of 941.48 mAh g -1 and maintaining 566.04 mAh g -1 after 1500 cycles, corresponding to an ultralow capacity decay rate of 0.027% per cycle. DFT calculations further suggested that oxygen-containing functional groups can provide polar adsorption/catalytic sites, reduce the conversion energy barriers of Na 2 S x species. Specifically, the carbon framework's carbonyl (C=O) and epoxy (C-O-C) groups can enhance the sulfur redox kinetics. Download: Download high-res image (308KB) Download: Download full-size image

In this study, a donor-acceptor (D-A) conjugated design strategy was used to synthesize a novel covalent organic framework (NLCOF, the COF initiated by Na Lv), using 2,5-dimethoxylterephthalaldehyde as the building block via the Kröhnke reaction. Subsequently, ZnIn 2 S 4 quantum dots (ZIS QDs) were physically combined with NLCOF for constructing a ZIS QDs-NLCOF S-scheme heterojunction composite photocatalytic system. This system achieved an H 2 O 2 production rate of 6 417 µmol·g −1 ·h −1 in pure water using the 40ZIS-NLC composite catalyst, which was 4.2 and 26.7 times higher than that of ZIS QDs and NLCOF, respectively. Upon adding 1 mL benzyl alcohol to the system, the H 2 O 2 production rate drastically increased to 53 383 µmol·g −1 ·within 5 h. Advanced characterization techniques, including XPS, KPFM, and EPR were employed to elucidate the intrinsic mechanism of S-scheme heterojunction photocatalytic H 2 O 2 production. This study offers insights into the rational design of high-performance COF-based heterojunction photocatalysts and provides a robust foundation for optimizing interfacial electron-coupling interactions to enhance overall photocatalytic efficiency.

Developing high-performance CO 2 -based polymers is promising to address the challenges of CO 2 sequestration and the environmental impact of petroleum-based plastics. The δ-lactone 3-ethylidene-6-vinyltetrahydro-2H-pyran-2-one and its derivatives, synthesized from CO 2 with 1,3-butadiene, have emerged as very promising CO 2 -derived monomers. However, their general ring-opening polymerizations face challenges with thermodynamics and kinetics, generally resulting in long reaction times, low conversions, and low-molecular-weight polyesters with poor mechanical properties. Herein, we report a dual isomerization-driven cationic ring-opening polymerization (DI-CROP) of a CO 2 -derived thionolactone, 3-ethyl-6-vinyltetrahydro-2H-pyran-2-thione, in which the relayed S/O and vinyl isomerizations significantly enhance polymerization activity, enabling the rapid synthesis of high-molecular-weight CO 2 -based polythioesters, achieving near-quantitative conversion within just a few minutes. Also, the relayed S/O and vinyl isomerizations in DI-CROP can easily migrate C=C substituents on the ring of thionolactone into its backbone. These features further enable the production of sustainable CO 2 -based materials through efficient copolymerization and post-polymerization functionalization. This study enriches the realm of isomerization-driven polymerizations, and provides a new synthetic approach to CO 2 -derived polymeric materials.

For achieving the broad-spectrum removal ability of g-C 3 N 4 materials for various contaminants, it is assessed as critical core by synchronously enhancing the solar absorption-conversion and PMS adsorption-activation process of g-C 3 N 4 materials. In this manuscript, S-scheme high-entropy FeMnCoNiCu-LDHs/self-assembly carbon nitride nanotubes (LDHs/SCN) heterojunction were established by mechanical-assisted ball milling, calcination, and hydrothermal method. Contributed to the synergistic effect of multi-metal elements in FeMnCoNiCu-LDHs materials, the photocatalytic PMS activation efficiency of LDHs/SCN composites is benefit from the efficient conversion of Fe 3+ /Fe 2+ , Mn 4+ /Mn 3+ , Co 3+ /Co 2+ , Ni 3+ /Ni 2+ , and Cu 2+ /Cu + redox cycles. So, under 0.1 mM PMS and visible light irradiation, the removal efficiency of bisphenol A (BPA), ciprofloxacin (CIP), 2-mercaptobenzothiazole (MBT), oxytetracycline (OTC), tetracyclines (TC), and sulfadiazine (SD) pollutants in LDHs/SCN-0.2/PMS/Light system reach to 91.1 %, 82.8 %, 94.7 %, 86.8 %, 91.4 % and 63.0 %, respectively. Furthermore, the enhancement mechanism of the photocatalytic PMS activation performance of LDHs/SCN-0.2/PMS/Light system has been elucidated through ESR, UPS, ROS quenching experiments, and band structure analysis. The LC-MS and T.E.S.T. software was successively employed for intermediates transformation pathways and bio-toxicity during BPA degradation. Consequently, this work lays a foundational basis for the design and construction of highly efficient S-scheme heterojunctions for advanced wastewater purification.

A flower-like S, N-codoped carbon nanosheets loaded with hybrid magnetic nanoparticles (HMNPs/S,N-CNSs) by using MOF as precursor was prepared. The morphology, composition, microstructure, and property were evaluated by SEM, HRTEM, EDS, XRD, XPS, magnetic analysis, and cyclic voltammetry. The hybrid nanoparticles were composed of most Fe 3 O 4 , some CoFe alloy, and a few Fe 2 S. The magnetic material showed high magnetism and brilliant electrocatalysis towards the electrochemical reduction of antibiotic nitrofurazone (NFZ). By utilizing screen-printed electrode (SPE) and HMNPs/S,N-CNSs, a disposable electrochemical NFZ sensor (HMNPs/S,N-CNSs/SPE) was fabricated by magnetic control. The current signal of NFZ at HMNPs/S,N-CNSs was 6.38 times higher than that of bare SPE. It displayed a wide detection range of 0.01–50 μM with a detection limit of 4.2 nM (S/N = 3). The practical applicability of the sensor in real samples presented satisfactory results. The disposability, low cost, high sensitivity, low consumption volume in analyses, and good selectivity make the proposed sensor a promising tool for NFZ detection.

The surface passivation deactivation and limited supply of Fe 2+ on nano zero-valent iron (nZVI, Fe 0 ) restrict activation of persulfate. Herein, L-cysteine modified cobalt-based ZIF derivative anchored Fe 0 (Fe 0 @ZIF-CoNS2) containing luxuriant oxygen vacancy (O v ) defects and bimetals was fabricated. The sintered bulk ZIF-CoNS2 and chain-shaped Fe 0 were disaggregated into rough and dispersed nanospheres, meanwhile, the loading of Fe 0 increased the specific surface area of ZIF-CoNS2 by 11 times. The peroxydisulfate (PDS) consumption efficiency of 96.11 % and the metronidazole (MNZ) removal efficiency of 96 % were achieved by the catalytic action of 0.18 g/L Fe 0 @ZIF-CoNS2. Compared than the unmodified system, the leaching concentrations of Fe and Co ions were reduced by 7.33 mg/L and 4.44 mg/L, respectively. The regulation of L-cysteine elevated the relative ratio of O v from 0.46 to 6.26 and augmented the electron transfer ability of precursor. Fe, Co and O v were identified as the main active sites, where O v played an important role as a medium in inducing sustainable generation of Fe 2+ /Co 2+ and 1 O 2 . The modified system fulfills the degradation of MNZ through plentiful 1 O 2 and scant free radical. This research offers insights into the formation of O v and enhancement of nZVI reactivity during advanced oxidation processes.
