Summary: This study investigates the use of liquid-hot-water pretreatment with FeCl3 for enhanced enzymatic saccharification of corn stalks and the use of lignocellulose residues as biosorbents for Cd adsorption. Through incubating Trichoderma reesei with corn stalks and FeCl3, increased enzyme activities were observed. The undigested lignocellulose residues were then carbonized with FeCl3, producing highly porous carbon for supercapacitors. Overall, FeCl3 was found to be a versatile catalyst for enhancing the conversion of lignocellulosic substrates.

Summary: The scope of bioengineering is expanding to include the design of microbial communities, and researchers have shown that a stable two-strain community can be achieved by engineering a strain of Escherichia coli to secrete a toxin in response to competition. Experimental and mathematical evidence demonstrates that this system can produce stable populations with tunable compositions controlled by easily adjustable parameters. This approach allows for the creation of tunable, stable two-strain consortia with the potential to interface with natural microbiomes.

Summary: This review discusses the strategies and recent advances in using microbial consortia to degrade complex compounds, including plastics, petroleum, antibiotics, azo dyes, and pollutants in sewage. It is shown that microbial consortia have advantages over isolated bacteria as they are more adaptable and stable, and can provide a suitable catalytic environment for each enzyme. The development of synthetic biology and gene-editing tools allows the design of artificial microbial consortia systems that are more efficient, stable, and robust.

Summary: In this study, a hybrid structure, MIL-53(Al)@MWCNT, was synthesized by combining MIL-53(Al) particles and -COOH functionalized multi-walled carbon nanotube (MWCNT). The hybrid structure was then embedded in a polyethersulfone (PES) polymer matrix to prepare a mixed matrix membrane (MMM) for CO2/CH4 and CO2/N2 separation. The addition of MWCNTs prevented MIL-53(Al) aggregation, improved membrane mechanical properties, and enhanced gas separation efficiency.

Summary: Non-conventional amines are being researched worldwide to overcome the limitations of traditional amines like MEA and MDEA. Adequate process and thermodynamic models are crucial for understanding the applicability and performance of these amines in CO2 absorption, but studies on process modeling for these amines are limited. This study used rate-based modeling and Deshmukh-Mather method to model CO2 absorption by DETA solution in a packed column, validated the model with experimental data, and conducted a sensitivity analysis of mass transfer correlations. The study also compared the CO2 absorption efficiency of DETA solution with an ionic solvent [bmim]-[PF6] and highlighted the importance of finding optimum operational parameters for maximum absorption efficiency.

Summary: The utilization of smart water in EOR operations has gained attention, but more research is needed to understand the complex mechanisms involved. This study investigated the interfacial tension between smart water and crude oil, considering factors such as salt, pH, asphaltene type, and aged smart water. The results revealed that the hydration of ions in smart water plays a key role in its efficacy, with acidic and basic asphaltene acting as intrinsic surfactants. The pH also influenced the interfacial tension, and the aged smart water's interaction with crude oil depended on asphaltene type, salt, and salinity.

Summary: In this study, high-performance solid catalysts based on phosphotungstic acid (HPW) supported on Zr-SBA-15 were synthesized and evaluated for the one-pot conversion of furfural (FUR) to γ-valerolactone (GVL). The catalysts were characterized using various techniques, and the ratio of HPW and Zr was found to significantly affect the selectivity of GVL. The HPW/Zr-SBA-15 (2-4-15) catalyst exhibited the highest GVL yield (83%) under optimized reaction conditions, and it was determined that a balance between Bronsted acid sites (BAS) and Lewis acid sites (LAS) was crucial for achieving higher catalytic performance. The reaction parameters and catalyst stability were also investigated.
