Summary: Biochar is a carbonaceous by-product of thermochemical processes that can be transformed into nano-biochar through size reduction. Nano-biochar exhibits superior physico-chemical properties compared to macro-biochar, including higher stability, unique nanostructure, improved catalytic ability, larger specific surface area, higher porosity, enhanced surface functionality, and active sites. It efficiently regulates the transport and absorption of nutrients and contaminants, but its toxicity and environmental concerns need to be extensively evaluated for large scale applications.

Summary: In this study, a mussel-inspired biosorbent combined with graphene oxide was developed for removing organic dyes from water sources. The composite was prepared by self-polymerization of dopamine in a weak alkaline solution containing graphene oxide. The morphology and structure analysis revealed that polydopamine gradually covered the surface of graphene oxide flakes, partially reduced these flakes, and formed small grains instead of large aggregates. The adsorption kinetics and isotherms of the biosorbent towards methylene blue followed pseudo-first order kinetics model and Langmuir isotherm. The as-prepared bio-sorbent shows great potential for remediating water sources contaminated with cationic organic molecules and heavy metal ions.

Summary: Nitrogen pollution and the increasing amount of wastewater generation require advanced wastewater treatments. Bioelectrochemical systems (BES) have been developed to simultaneously produce electricity and remove resistant nitrogen from carbon-deficient wastewater. However, BES alone cannot achieve the simultaneous removal of multi-species inorganic nitrogen. This review discusses the latest developments in BES-enhanced denitrification and multiple coupled BES-based denitrification pathways.

Summary: In recent years, water scarcity has become a significant problem due to population growth, industrial progress, and climate change. Water pollution caused by hazardous pollutants like toxic metals and phenolic compounds demands urgent attention. Coal fly ash and coal bottom ash wastes have been explored as low-cost raw materials for producing suitable materials for cleaner wastewater treatment. These materials have shown promise in removing toxic metals and phenolic compounds through adsorption, membrane filtration, and photocatalysis. Future research should focus on recycling coal ashes and advancing processes for more efficient wastewater remediation.

Summary: Despite mass vaccination, lockdowns, and other measures, the transmission of COVID-19 continues. This is due to our limited understanding of droplet transport and viral transmission dynamics. This review explores the effects of various factors, such as droplet size, environmental conditions, virus mutation, and non-volatile components, on droplet evaporation and dispersion, as well as on virus stability. Experimental and computational methods for analyzing droplet transport are presented, along with controlling factors such as environmental conditions, turbulence, ventilation, and droplet size distribution. Results indicate that relative humidity and temperature play a significant role in droplet behavior and virus viability.

Summary: Floods can cause the release and remobilization of organic pollutants, leading to their accumulation in floodplains. The size and frequency of floods have an impact on the distribution, remobilization, and accumulation of organic contaminants. The introduction of wastewater pollutants during floods should be given special attention. Organic indicators provide valuable information on specific distribution patterns and the influence of tributaries and structural measures, and they serve as an important basis for assessing short- and long-term environmental risks.

Summary: Switching the properties of gC(3)N(4) using solvents like water or ethanol can efficiently enhance its photogenerated carrier separation and transfer. The gC(3)N(4) synthesized with solvents demonstrated superior photocatalytic activity compared to the one obtained without solvent, particularly gC(3)N(4)-H2O. The latter showed a yield of up to 32% after annealing at 550°C and achieved a photocatalytic degradation rate of 48% for sodium diclofenac under simulated sunlight after 120 min of irradiation.

Summary: The presence of metal foam in phase change materials (PCM) improves the storage of latent heat thermal energy but reduces natural convection and increases cost. We studied the internal flow of heat transfer in a PCM filled with metal foam at different filling heights. Results show that the configuration of bottom-filled PCM has higher natural convection and shorter melting time in the pure PCM area. However, the melting time is longer in the bottom-filled configuration in the metal foam-PCM composite region.

Summary: Gradient metal foam was studied for its heat transfer performance and bubble behavior in this experiment. The positive gradient configuration showed better heat transfer performance, reaching 6.14x105 W/m2, compared to the uniform metal foam surface of 3.94x105 W/m2. Boiling heat transfer performance increased and then decreased with pore density for the positive gradient, while it remained nearly constant for the inverse gradient. Different bubble escape behaviors were observed for the two configurations, with larger bubbles and higher bubble detachment frequency on the positive gradient surface. Two liquid replenishment models were proposed for the different configurations.
