Water electrolysis is widely regarded as a sustainable approach for hydrogen production. Recently, coupling thermodynamically favorable sulfide oxidation reaction (SOR) with the hydrogen evolution reaction (HER), has emerged as an effective strategy to reduce energy input while enabling simultaneous sulfide wastewater treatment and energy-efficient hydrogen production. This review provides a comprehensive overview of recent advances in SOR-assisted water electrolysis, with a particular emphasis on nanostructure engineering strategies for high-performance electrocatalysts. We first elucidate the fundamental mechanisms of SOR and HER, highlighting key intermediates, reaction pathways, and kinetic limitations. Subsequently, state-of-the-art catalyst design strategies are systematically summarized, including single-atom design, vacancy engineering, heteroatom doping, alloying, interfacial engineering, and surface regulation, with a focus on how these approaches modulate electronic structures, optimize adsorption behaviors, and enhance catalytic performance. In addition, emerging applications such as self-powered hydrogen production systems and SOR-assisted seawater electrolysis are discussed to demonstrate the practical potential of this technology. Finally, current challenges and future perspectives are outlined to provide valuable insights into the rational design of advanced electrocatalysts and the development of sustainable SOR-related electrochemical technologies.

This work introduces a novel, green switch on-off spectrofluorimetric quenching method using erythrosine B (EB) for nano-trace determination of pentoxifylline (PTX) or donepezil HCl (DPZ) in tablets and spiked plasma, enabling rapid clinical monitoring. The suggested approach relies on the quenching effect of either DPZ or PTX on the intrinsic fluorescence of EB, various experimental conditions influencing fluorescence quenching were investigated and optimized. An ion pair complex is formed between the cationic amino group in either drugs and the anionic phenolic group of EB at mild acidic conditions using Britton-Robinson buffer. After excitation at 528 nm, the fluorescence quenching intensities were measured linearly at 552 nm across the range (50-1000 ng/mL) for PTX with quantification limits of 16.76 ng/mL and over the range (20-500 ng/mL) for DPZ with limit of quantification 17.56 ng/mL for DPZ. The suggested method exhibited high % recoveries, confirming its reliable applicability in complicated matrices. The validation of the suggested methodology was further performed in accordance with the International Conference of Harmonization (ICH Q2R2) recommendations. Furthermore, the method's greenness, blueness and whiteness profiles was investigated, revealing its remarkable sustainability.

Cellulose has been integral to a range of essential applications throughout history and remains relevant today. This research highlights an important topic: the study of cellulose-based and wood-derived supports in works by Portuguese artists from the twentieth century. Such an investigation is valuable for conservation and heritage science, as materials such as cardboard, plywood, hardboard, and particleboard are common in modern and contemporary artworks but are often not thoroughly characterized or discussed. Micro-infrared spectroscopy, when combined with reference materials, offers a promising means of identifying and analyzing these supports. The study focuses on works by Portuguese artists from 1915 to 1986. Applying principal component analysis to infrared data in the 1000–1200 cm−1 range enabled us to distinguish among the artists. For Pomar, Rodrigo, Vespeira, Calvet, and Hatherly, using hardboard in this range appears most suitable. For Salazar, Teles, and Pinheiro, particleboard is the optimal choice. Beech and eucalyptus plywood are preferable for Pires Vieira and Carlos Botelho. The effort to connect material knowledge with sustainable conservation practices is commendable. The research also aims to relate cellulose-based supports adhering to the European Union’s Sustainable Development Goals, fostering more sustainable and meaningful approaches to cultural preservation.

In 2023, our emergency department, serving a region with one of the highest rates of new HIV infection, implemented Centers for Disease Control and Prevention-recommended universal, opt-out HIV screening for adolescents. However, few patients admitted to the pediatric hospital medicine service (PHM) were tested. To address this gap, we aimed to expand universal, opt-out HIV testing to PHM and evaluate screening implementation. In this pre-postintervention study, we compared HIV testing rates for patients admitted to PHM aged 13years or older during 5months preimplementation and postimplementation (February to June 2024 and July to November 2024). Clinicians received regular education on HIV screening guidelines and opt-out language and were encouraged to incorporate screening in confidential psychosocial assessments. If the inpatient team did not offer testing, HIV navigators counseled adolescents, regardless of parental presence. Testing rates were compared with chi-square and Welch's t-test. There was a 38% increase in HIV screening from the preimplementation to postimplementation periods (preimplementation, 12.4%; postimplementation, 17.1%; P = .04). Postimplementation, 533 adolescents were eligible for HIV screening; 148 were approached, and 91 HIV tests were ordered (17.1% of eligible; 64% girls; mean age 16 ± 1.8years), identifying one adolescent with HIV (>1% seroprevalence; 3% for boys). Adolescents were significantly more likely to be tested when approached by an HIV navigator than during a confidential interview (P = .004). Parental presence did not negatively impact adolescent participation. Adopting universal, opt-out HIV screening with HIV navigators in the inpatient setting significantly increased testing rates. Further studies on the most effective and sustainable approach to screening are needed.

In the 5G era, electromagnetic pollution poses an invisible threat to human safety. Given that electromagnetic wave (EMW) absorption invariably generates heat, this phenomenon may induce structural degradation of the material and pose safety risks. It is crucial to develop high-strength, flame-retardant electromagnetic interference (EMI) shielding materials. Herein, we propose a green and sustainable approach to induce stable dispersion of carbon nanotubes (CNTs) with in situ lignin and non-covalent bonding in waste bamboo materials. The in situ lignin released during bamboo fiber pretreatment was utilized as a "bridge" to enhance the interfacial bonding between CNTs and the fibers, and co-assembles with the CNTs through inter-boundary hydrogen bonding, electrostatic stabilization, and π-π stacking. Then, biocomposites were synthesized in one step by hot pressing, using molten in situ lignin as a green binder for self-bonding. The biocomposite exhibits excellent EMI shielding performance (72.5dB), superior mechanical properties, flame retardancy (total heat release reduced by 35.22%, Total smoke production reduced by 81.58%). It offers a sustainable approach to developing multifunctional structural materials for the construction, aerospace, and military sectors.

Sustainable approach to anaerobically treat high-strength distillery wastewater for renewable energy recovery: Start-up strategy, reactor performance, and kinetic evaluation

The sustainable mitigation of antibiotic and herbicide residues requires materials that integrate effective contaminant sequestration with soil quality improvement. Here, we present a novel, scalable strategy for synthesizing artificial humic substances (AHS) from poplar bark via alkaline hydrothermal humification, which accelerates natural humification pathways and generates a supramolecular structure rich in carboxyl, pHenolic, and quinone functional groups. The engineered AHS was assessed for selective removal of tetracycline (TC), sulfamethoxazole (SMX), and atrazine (ATZ). Under optimized neutral conditions (pH 7.0, ambient temperature), AHS achieved adsorption capacities of 65.8, 10.7, and 10.8 mg/g for TC, SMX, and ATZ, respectively, driven primarily by hydrogen bonding, π–π stacking, and electrostatic forces. Kinetic analysis followed a pseudo-second-order model, and equilibrium data were consistent with the Langmuir isotherm (R 2 ≥ 0.985), indicating monolayer adsorption on a mesoporous surface. Competitive adsorption experiments demonstrated strong selectivity toward TC (K TC/SMX = 5.21; K TC/ATZ = 2.56). Soil amendment with AHS significantly enhanced pollutant immobilization, achieving >95% removal of TC and SMX after four weeks of aging. Dynamic leaching experiments demonstrated that a layered AHS-soil configuration functions as a superior reactive barrier compared to homogeneous mixing. Collectively, these results demonstrate that poplar bark-derived AHS offers a robust, bifunctional platform for integrated water purification and soil remediation, providing a practical and environmentally sustainable approach to mitigate organic pollutants. • Artificial humic substance synthesized from poplar bark via hydrothermal treatment. • AHS effectively adsorbed antibiotics and herbicides from aqueous and soil systems. • Adsorption followed the pseudo-second-order kinetics and Langmuir isotherm model. • AHS-amended soils demonstrated contaminant removal after four weeks of incubation. • Layered AHS configuration exhibited superior leaching control and pollutant retention.

Isolation and characterization of Acetobacter tropicalis from kombucha as an acid-tolerant, high-yield producer of bacterial cellulose.

This study focused on the critical environmental problem of harmful synthetic dyes being discharged into aquatic environments, which cannot be purified by conventional methods. We investigated the removal of methyl orange (MO) using Ceriporia lacerata RF-7, a recently discovered white-rot fungus, as a potent bioadsorbent. SEM and BET analyses of the biomass structure and texture revealed a complex, porous hyphae with sufficient surface area for dye adsorption, as well as a large specific surface area and mesoporous structure that promotes molecular diffusion. The efficiency of bioadsorption was significantly influenced by pH and temperature, achieving a maximum removal rate of 95.0% at pH 4. High removal efficiency was maintained up to 40°C, and at 30°C, the adsorption process was found to be thermodynamically spontaneous. This thermal stability shows that treating industrial wastewater does not require rigorous temperature control and is an energy-efficient method. Equilibrium results confirmed the Langmuir adsorption isotherm model (R2 > 0.999) and demonstrated a significant maximum monolayer adsorption capacity of 185.10 mg/g, surpassing many commercially available and biological adsorbents. Kinematic studies demonstrated that the bioadsorption process adheres to a pseudo-second-order reaction mechanism, indicating that the rate-limiting step is influenced by both definite chemisorption and surface interactions. Thermodynamic studies show that the process is spontaneous (∆G° < 0), is endothermic (∆H° = +58.20 kJ/mol), and leads to greater disorder at the solid-liquid interface (∆S° = +224.0 J/mol·K). These findings underscore RF-7 as a strong, environmentally friendly, and highly effective biosorbent, providing a sustainable approach for the efficient treatment of industrial wastewater contaminated with dyes.
