Summary: This study investigated the adsorption of diethyl phthalate (DEP) by biochar samples derived from different feedstocks. The results showed that giant reed biochar had the highest adsorption capacity due to its larger surface area. An increase in solution pH reduced the adsorption capacity, while an increase in sodium ionic strength enhanced the adsorption. Additionally, the adsorption process was spontaneous and exothermic at a lower temperature.

Summary: Pyrolysis is a thermochemical process to convert biomasses into energy and biochar. Sludge biomass from wastewater treatment plants shows potential as a pyrolysis feedstock, with the efficiency of biochar in wastewater treatment influenced by various factors. Physico-chemical properties and adsorption efficiency of sludge-derived biochars are influenced by raw sludge nature, pyrolysis conditions, and pre/post-treatments, indicating the potential for improved nutrient recovery and heavy metal adsorption.

Summary: In this study, conventional and Graphene Oxide-engineered biochars were produced and characterized, and their potential as adsorptive materials was investigated. The effects of biomass type, Graphene Oxide functionalization, and pyrolysis temperature on biochar properties were studied. The results showed that biomass type and pyrolysis temperature were the main factors affecting biochar structure, while GO functionalization caused significant changes on biochar surface. The best biochars for adsorption efficiency were the GO-functionalized biochars produced from Rice Husks at 600°C, and the most difficult pollutant to remove was 2.4-Dichlorophenol.

Summary: This article explored the adsorption-desorption processes of typical heavy metal pollutants in sediments under different conditions and designed different binary competitive adsorption systems to study the competitive adsorption properties of heavy metal contaminants. The sediment adsorption rates for heavy metals were Cu>Pb>Cd>Zn, and the desorption rates were Cd>Cu>Zn>Pb. The removal of organic matter decreased the ability of sediment to sequester heavy metals, and interfering ions had the greatest effect on Cd and the least effect on Pb. The adsorption and desorption of heavy metals in sediments increased with temperature, and the presence of organic matter increased the sequestration ability of sediment for Cd, Pb, Cu, and Zn. Heavy metals also exhibited significant selective adsorption properties.

Summary: Plastic pollution is a global environmental issue, and the removal of inherent plasticizer has gained significant attention. This study investigated the characteristics and performance of biochars derived from six different biomass wastes in China for the adsorption of diethyl phthalate (DEP), a frequently detected plasticizer in water. The results showed that the properties of biochars, such as porosity, specific surface area, and surface functional groups, varied with the feedstock type, which influenced the adsorption and desorption of DEP. The adsorption mechanisms involved hydrophobic effect, micropore filling, hydrogen bonding, and pi-pi EDA interactions. Among the biochars, giant reed biochar exhibited high DEP adsorption capacity and low desorption, making it an efficient and environmentally friendly sorbent for DEP removal. These findings are important for the production of designed biochars from different biomass wastes to control plasticizer pollution.

Summary: In this study, EPS polysaccharides were extracted from Enteromorpha prolifera and cationic modification was performed to obtain CAEPS hydrogel. The structural characteristics of EPS and CAEPS-based hydrogel were analyzed, showing that CAEPS hydrogels have higher porosity, apparent density, and hydrophilicity compared to EPS hydrogels. The adsorption mechanism of the hydrogels on three typical pollutants in water was studied, with the results indicating that the adsorption isotherms of both hydrogels followed the Langmuir model and the adsorption capacity of CAEPS hydrogels was higher than that of EPS hydrogels.

Summary: In this study, magnetic and nonmagnetic biochars were compared for their adsorption capabilities, revealing that magnetization reduced the adsorption capacities due to decreased importance of cation-exchange and C pi-coordination in the biochars. This reduction in adsorption capacity suggests that conventional biochar may be more effective in adsorbing Cd2+ than magnetized biochar. Further research on magnetic biochars as sustainable alternatives for remediation of Cd-contaminated environments is recommended.

Summary: Passive daytime radiative cooling (PDRC) technology, while promising for global spacing cooling, faces limitations in practical application due to reduced cooling effectiveness caused by wear and dirt contamination. Researchers have developed a renewable armor structure using fluorinated hollow glass microspheres to enhance the anti-fouling and cooling properties of PDRC coatings. The coatings exhibit high solar reflectance and thermal emittance, leading to significant temperature reduction below ambient temperature.

Summary: Methane chemistry is a significant area of research in catalysis. Converting methane into value-added chemicals is desirable but challenging due to its high C-H bonding energy and lack of pi bonding or unpaired electrons. Photocatalytic partial oxidation of methane to liquid oxygenates is a promising technology for achieving high efficiency and selectivity under mild conditions. The choice and activation of oxidants are crucial for its performance.
