Summary: The ZIF/AC materials were prepared by loading trace amounts of ZIF-67 onto commercial activated carbon and calcining at different temperatures. The Co/AC-800 material showed highly dispersed Co and N on its surface, which contributed to its superior adsorption desulfurization performance for DBT compared to the two matrix materials. The acid-base interaction and π-π interaction were identified as the main factors, supported by quasi-second-order kinetics and Langmuir model analysis.

Summary: In recent years, heteroatom-doped microporous carbons have attracted significant attention as emerging CO2 adsorbents. However, the role of small-sized micropores and heteroatom content on CO2 adsorption has rarely been studied. In this study, sucrose-derived porous carbons with different ratios of KOH and urea content were synthesized, and their textural features and CO2 adsorption capacity were investigated. The carbons showed remarkable surface area and micropore volume, with the optimized sample achieving a CO2 uptake of 8.19 mmol g-1. The nitrogen moieties in the carbons were found to contribute to the selective separation of CO2 from N-2 gases. In conclusion, the narrow micropores and optimal nitrogen content played a crucial role in achieving excellent CO2 adsorption performance in these carbons.

Summary: In this study, an N-doped magnetic carbon skeleton was developed as a porous adsorbent matrix with strong affinity adsorption sites and excellent selectivity properties for the removal of phenol from wastewater. By adjusting the thermal treatment condition, the pore volume and specific surface area of the adsorbent matrix could be finely tuned, resulting in an N-rich matrix structure with flexible mass transfer channel. The imprinted modification created phenol-shaped geometrical cavities on the matrix, activating the phenol recognition of N-active sites and providing selective adsorption property. The adsorbent demonstrated superior adsorption capacity and selective recognition towards phenol, outperforming previously reported adsorbents. Its easy magnetic separation property also allowed for excellent reusability. This adsorbent shows promising potential for separating pollutants from wastewater and contributes to the design of efficient comprehensive adsorbents.

Summary: NACs were fabricated as an adsorbent with large specific surface area and high micropore percentage. The sample NAC-650-650 showed the highest CO(2) adsorption capacity and selectivity under 1 bar pressure, maintaining over 97% capacity after ten cycles. The CO(2) capacity of NACs has a linear correlation with the cumulative pore volume for pores less than 1.02 nm, and the presence of nitrogen and oxygen enhances CO2/N2 selectivity.

Summary: With global warming and climate change being a reality, international investments are increasingly being made in climate change mitigation. Carbon capture and separation (CCS) is gaining paramount importance as an effective solution for global warming. Sorption on porous materials, especially natural products-derived porous carbons, shows promise as an alternative to traditional CO2 capture technologies due to their sustainable availability, economic viability, and recyclability. This review provides crucial insights and analyses on the application of porous carbons in CO2 capture, including synthesis methods, structural characterization, and the use of simulation techniques. The review also outlines future research directions to progress the use of natural products-derived porous carbons for CO2 capture.

Summary: Capacitive deionization (CDI) is a promising technology for salt removal from brackish water, and the performance relies on the electrode materials. This study investigated three ZIF-67-derived porous carbon nanomaterials and found that ZCNB exhibited the highest adsorption capacity due to its large specific surface area, good wettability, high surface charge, and suitable pore sizes. The presence of carbon nanotubes in other materials decreased their adsorption capacity.

Summary: Long-term nitrogen deposition can change the abundance and community composition of soil nematodes, affecting the soil food web and biogeochemical cycling. In Cunninghamia lanceolata forest, nitrogen addition increased the abundance of bacterial-feeding nematodes but reduced the abundance of plant-feeding nematodes. Furthermore, nitrogen addition indirectly affected the abundances of bacterial, fungal, and plant-feeding nematodes via changes in soil nutrients, soil water content, and pH.

Summary: Despite progress in purifying C5-C9 linear alpha-olefins from Fischer-Tropsch synthesis products, the separation of olefins and paraffins with the same carbon number hampers their industrial development. This study proposes a process that uses zirconocene/methylalumoxane catalyst for selective dimerization of linear alpha-olefins, followed by distillation and catalytic conversion into branched-chain sulfonate surfactants. The resulting surfactants outperform commercially used linear alkylbenzene sulfonate in terms of surfactant properties and detergency performance.

Summary: This paper investigates the time-varying formation tracking control problem for multi-agent systems (MASs). The main objective is to achieve asymptotic convergence of formation tracking error despite nonparametric and nonvanishing uncertainties. A fuzzy extended state observer (FESO) based on event-triggered mechanism is proposed to estimate unmodeled dynamics and external disturbances. Furthermore, a distributed control law is developed using neighborhood formation tracking errors, and total disturbance compensation is introduced to attenuate uncertainty influence in real time. The effectiveness of the proposed control protocol is demonstrated using a numerical example on unmanned aerial vehicle swarm system.

Summary: Celastrol was transformed by Streptomyces olivaceus CICC 23628, resulting in the isolation of two new friedelanes derivatives (CEL-1 and CEL-2) as metabolites. Their structures were elucidated through NMR and HR-MS analysis. In vitro studies demonstrated that CEL-2 could induce apoptosis and block the cell cycle in HCT-116 cells. Western blotting analysis showed that CEL-2 inhibited STAT3 phosphorylation and downstream gene expression. Moreover, SPR analysis confirmed the direct binding of CEL-2 with STAT3 protein. These findings suggest that CEL-2 may have potential as an anti-colorectal cancer agent by inhibiting STAT3 and inducing apoptosis and cell cycle arrest.

Summary: A new species called Sinocyclocheilus xingyiensis was discovered in a karst cave in Guizhou Province, China. The authors used both morphological and molecular data to identify the new species as part of the Sinocyclocheilu angularis group, and it differs from other species in the group due to certain distinguishing features. Phylogenetic analyses based on the cyt b gene fragment indicate that S. xingyiensis is closely related to Sinocyclocheilus flexuosdorsalis, with a genetic distance ranging from 1.2% to 15.4% compared to the S. angularis group.

Summary: This study investigated the effects of Konjac glucomannan (KGM) on the aggregation patterns and structural properties of weak, middle, and strong gluten. The results revealed that 10% KGM substitution resulted in decreased aggregation energy for middle and strong gluten, but increased for weak gluten. Additionally, 10% KGM enhanced the aggregation of glutenin macropolymer (GMP) in weak gluten, but suppressed it in middle and strong gluten. Furthermore, 10% KGM induced a transition from alpha-helix to beta-sheet in weak gluten, while causing more random-coil structures in middle and strong gluten. The network of weak gluten became more continuous with 10% KGM, whereas it was severely disrupted in middle and strong gluten.
