One of the pressing concerns in national security and catastrophic environmental pollution is the detection of nitro-aromatics owing to their explosive nature. In the past few decades, many efforts have been dedicated to developing novel fluorescent materials particularly aggregation-induced emission luminogens with high selectivity and ultra-sensitivity for the trace detection of various nitro-aromatics, especially nitro-explosives. The present review begins with a brief introduction to various sensing mechanisms involved in the detection of nitro-aromatics. A detailed description of state-of-the-art aggregation-induced emission active fluorescent materials for nitroaromatics detection over the last decade with a special focus on tetraphenylethylene based luminogens has been provided. Finally, the challenges and future outlooks of research in the development of tetraphenylethylene conjugates for the detection of nitro-aromatics have been discussed.

The emission of significant amounts of CO from human industry has caused severe environmental damage, necessitating effective CO capture methods for sustainable development. Membrane technology stands out as one of the most effective and economical solutions. In recent decades, polymer membranes have been recognized for their viability in gas separation applications. Aliphatic polycarbonates (APCs) are particularly notable due to their high chain segment flexibility, degradability, ease of processing, and the presence of carbonate groups, which enhance their affinity for CO. This study uses a one-pot melt polycondensation process to synthesize three high-molecular-weight APCs: poly(1,4-butylene carbonate) (PBC), poly(1,5-pentamethylene carbonate) (PPC), and poly(1,6-hexamethylene carbonate) (PHC) from dimethyl carbonate and various diols. To improve the mechanical properties of the APC separation membranes, capping modification was applied. The molecular weights of PBC, PPC, and PHC were 6.48 × 10 g/mol, 4.78 × 10 g/mol, and 5.76 × 10 g/mol, respectively. These membranes were prepared by the evaporative solvent method. The PHC membrane demonstrated a CO permeability of 20.84 Barrer and a CO/N selectivity of 22.24 at 35 °C under 0.1 MPa, approaching Robeson’s upper bound and indicating substantial potential for application.

Sulfadiazine (SDZ) is an antibiotic frequently detected in natural water environments and wastewater treatment systems. Its accumulation and residue in aquatic seriously impact ecosystems and human health. (PK) is an invasive species that seriously impacts the production of agriculture, forestry, and animal husbandry due to its strong adaptability and fast diffusion speed. In order to transform exotic noxious weeds into valuable resources, biochar (PKBC) was prepared by pyrolyzing the stems of PK at 500 °C to adsorb SDZ effectively. The results demonstrated that the biochar material exhibited a plate-like morphology with a large specific surface area, which provided numerous adsorption sites and was conducive to SDZ adsorption. The pH value significantly affects the adsorption of SDZ on PKBC-500, with better adsorption performance in acidic environments. The adsorption capacity of PKBC for SDZ was determined to be 6.87 mg/L. The adsorption kinetics and isotherms were analyzed, and the pseudo-second-order kinetic better fitted the adsorption process of SDZ. The Freundlich equation was more appropriate for explaining the adsorption process. In summary, biochar adsorption of antibiotics was prepared using PK pyrolysis. Its raw material is inexpensive and can effectively adsorb SDZ while solving the problem of invasive plant management.

Contaminated water is one of the world’s largest health and environmental problem. Emerging pollutants, such as pharmaceutics, are raising increasing concerns, as they are non-regulated toxic chemicals found in low concentrations that are very resilient to conventional water treatments. In the search for effective methods to address this problem, photocatalysis arises as a possible solution to degrade organic pollutants. TiO is one of the most widely used catalysts, but the reduced photoactivation under visible radiation constitutes a major drawback. The inclusion of plasmonic nanoparticles, such as gold (AuNPs), can improve the ability to absorb visible radiation from sunlight. AuNPs synthesis methods include toxic and expensive reagents. Herein, an alternative method is proposed, using the flavonoid quercetin to act as the reducing agent in the deposition of AuNPs on the surface of TiO (Au/TiO). The method is optimised, and different loadings of gold are tested. The characterisation of Au/TiO confirms increased absorption in the visible wavelength range with increasing concentrations of gold as well as a reduction in the energy band gap. The photocatalytic efficiency of Au/TiO was evaluated for the degradation of the antibiotic ciprofloxacin under UV and simulated sunlight irradiation, obtaining a maximum degradation of 86 and 95%, respectively.

The multi-scale hybrid surface can significantly enhance the boiling heat transfer efficiency. This review aims to provide an overview of the boiling heat transfer process, research developments, and potential applications of multi-scale hybrid surfaces. It has been discovered that the enhanced boiling mechanism on the multi-scale hybrid surface also involves some mixability due to a combination of different scale structures. A comprehensive analysis of the boiling process is essential for the numerical evaluation of the hybrid surface, considering the fluid parameters and operational conditions. The expressions related to bubble dynamics necessitate consideration of the shape and size of the cavity, wettability, heat flux, and system pressures. The characteristics of the preparation process should be considered when marking the hybrid surface. The application of multi-scale hybrid surfaces requires consideration of wettability and size range. It is crucial to select adaptable modified surfaces that fulfill the necessary heat transfer requirements when designing and constructing hybrid surfaces.

In this paper, a method for the simultaneous detection and degradation of tetracycline antibiotics (TCs) in water was investigated. Calcium silicate hydrate (CSH), FeO and calcium aluminate hydrate (CAH) were isolated from steel slag as carriers for Pt monomers. The produced Pt-modified modified steel slag (ALANH-Pt) possessed both peroxidase activity and photocatalytic properties. As a result, a sensitive and selective colorimetric sensor was exploited on the basis of ALANH-Pt for tetracycline (TC), oxytetracycline (OTC), and doxycycline (DOX), which exhibited a detection limit (LOD) of 1.696 μM, 0.999 μM and 3.607 μM, respectively. In addition, the degradation rate for TCs could be achieved 82 % within 60 min. The possible mechanisms of detection and degradation are discussed based on ESR spectroscopy, revealing the generation of hydroxyl radicals (OH), superoxide radicals (O) and holes (h). The degradation pathway of TC was inferred by HPLC-MS. The selectivity of the colorimetric sensing platform and the application of the bifunctional ALANH-Pt to real water samples were investigated. This work provides a new idea that allows for the simultaneous detection and degradation of TCs, and offers a new approach to the utilization of steel slag.

Magnetron-sputtered membranes have been an interesting candidate for water and gas treatment applications because of their controllable thickness, chemical compositions, crystalline structure, and other surface properties. Using magnetron sputtering (MS) as a reproducible and scalable deposition technique, membranes can be directed fabricated or modified through deposition of a thin layer on a support layer. The fundamental concepts, detailed processing mechanism, and various types of this technique are first outlined. Then, the applications of this technique in depositing thin films, mainly originating from polymers, metal(loid)s, oxides, and carbon, on membrane supports are briefly discussed. The next focus is on recent progress in this field by reporting the performance of MS-based developed membranes in both water and gas treatment processes, which provides a comparative study in terms of filtration efficiency. Finally, the current challenges and future directions are briefly provided for the development of next-generation magnetron-sputtered membranes.

Photocatalysis technology has been widely studied for treating Cr(VI) pollution in water and constructing heterogeneous structures presents a compelling approach to enhance the efficiency of Cr(VI) treatment. Pitifully, solely utilizing heterostructure, especially random composites of heterogeneous photocatalysts, often falls short of effectively enhancing the separation efficiency of photogenerated carriers. Furthermore, most photocatalysts interact weakly with the Cr(VI) anions, greatly reducing the utilization efficiency of photogenerated carriers. Herein, pyridine-based conjugated imprinted polymer (CIP) photocatalyst was precisely coated on urchin-like TiO using an in-situ condensation approach, forming a compact core–shell structure of organic/inorganic heterojunction. On the one hand, the compact heterojunction structure of the core–shell effectively improved the separation efficiency of photogenerated carriers. On the other hand, CIP enhanced the adsorption between the photocatalyst and Cr(VI), effectively improving the utilization efficiency of photogenerated carriers. Due to the collaborative effects of selective adsorption and core–shell heterojunction photocatalysis, the photocatalyst demonstrated remarkable performance in eliminating Cr(VI). For high concentration Cr(VI) pollution of 100 ppm, complete elimination could be achieved within 90 min. This research presented an innovative and efficient approach for the precise synthesis of photocatalysts.

Li[NiMnCo]O (NCM) has attracted considerable attention as a cathode material because of its excellent electrochemical performance; however, practical application of NCM is challenging owing to side reactions in the electrolyte and structural changes. In this study, we manufactured NCM electrodes with mixtures of Super-P and vapor-grown carbon fiber (VGCF) as conductive additives at different ratios (Super-P/VGCF=2/8 (S2V8), 5/5 (S5V5), and 8/2 (S8V2)) and investigated the effect of the ratio of the conductive additives on NCM electrode performance. Simply changing the ratio of the conductive additives without modifying the NCM active materials substantially altered the electrochemical performance. Using a Super-P/VGCF mixture at an appropriate ratio (5/5, w/w) forms a conductive network throughout the NCM active materials, improving the electrical conductivity and enabling uniform activation across the range of NCM particles. Consequently, for S5V5, the anisotropic volume changes of the NCM primary particles became uniform, resulting in structural stability of the secondary NCM particles during charging and discharging.

This study introduces a novel hydrothermal method that ingeniously couples the treatment of WSAA with the synthesis of high-quality carbon quantum dots (CQDs), offering a cost-effective and controllable approach. Through this method, the particle size and surface functional groups of the resulting CQDs can be precisely regulated. The average particle size tunes from 17.97 nm to 2.42 nm via increasing the hydrothermal temperature, and nitrogen-containing groups can be introduced through adding nitrogen sources during hydrothermal process. The prepared CQDs exhibit notable performance in photocatalysis and heavy metal detection, such as CQDs modified graphite carbon nitride has improved photocatalytic degradation ability and Hg (II) detection ability. Additionally, the environmental impact of the proposed method is substantially minimized, demonstrating a smaller footprint on ecosystems compared to conventional industrial disposal processes. Moreover, the economic cost associated with the method is significantly reduced by approximately 48.4 %, further highlighting its efficiency. Utilizing WSAA as a raw material for CQDs not only facilitates the recycling and sustainable utilization of waste but also enables low-cost production of high-performance carbon materials, presenting a mutually beneficial approach.
