Summary: With the increasing demand for energy, the development of high-performing drilling fluids and additives that are environmentally compatible for shale gas formations has become crucial. The synthesis and characterization of carboxymethyl chitosan (CM-CS) was conducted, and it was used as an additive in a water-based drilling fluid system. Various tests were performed and the results showed that CM-CS improved the drilling fluid properties compared to the conventional shale inhibitor, PEG. CM-CS demonstrated minimal interaction with Indian shale samples, suggesting its suitability for drilling fluid applications in troublesome shale gas formations.

Summary: The efficient strategy of achieving high ionic conductivity and durability for anion exchange membranes (AEMs) is demonstrated through the suitable microphase separation morphology. By blending hydrophilic oligomers of polyethylene glycols (PEGs) with different molecular weights, interconnected nano-channels are formed in the AEMs for enhanced ion conduction. The membranes containing 2 wt% PEGs with a molecular weight of 2 kDa exhibit significantly higher hydroxide conductivity and peak power density compared to pristine membranes.

Summary: Adding organically modified bentonite can improve the adsorption of organic pollutants in impervious wall materials. This study investigated the migration of organic pollutants in soil columns using two materials, one mixed with cetyltrimethylammonium bromide organically modified bentonite (CTMAB bentonite) and sodium bentonite, and the other mixed with kaolin and CTMAB bentonite. The results showed that the permeability coefficients and adsorption performance varied depending on the composition of the materials, providing a technical means for the design of organic pollutant cut-off walls.

Summary: Desiccant composites with channeling morphologies in the polypropylene (PP) matrix, prepared using polyethylene glycol (PEG) with different molecular weights (Mw) and molecular sieves (MS), exhibit microphase separation morphology caused by the channeling structure. PEG with an Mw of 8000 shows higher chemical compatibility with MS, leading to more stable channeling structure and significant moisture absorption. These composites can be utilized for novel desiccant packaging in the food and pharmaceutical industries.

Summary: Aqueous polymer quenchants are increasingly used in the quench hardening of steels. The inverse solubility property of polymer media leads to polymer film encapsulation of the quenched component, followed by an instantaneous rupture of the polymer film. The effect of molecular weight of Polyethylene glycol (PEG) on heat transfer characteristics and rewetting kinematics of PEG/water quenchants was studied. An increase in the molecular weight of PEG changed the rewetting kinematics from a local wetting front movement to an instantaneous rupture of the polymer film, resulting in increased uniformity of heat transfer.

Summary: In this study, palm oil mill effluent (POME) was treated via fermentation to produce a high-value biohydrogen (H-2) mixture. The H-2 was then enriched using absorption column and membrane contactor system, with the absorption column showing superior ability to purify H-2 while the membrane contactor system demonstrated higher sustainability during the separation process. Both techniques have their own advantages in purifying H-2 and can be considered for gas upgrading.

Summary: The study compared the performances of eco-friendly chitosan with industrial coagulants in treating water samples with turbidity and pH variations. Chitosan showed efficient removal of turbidity and metals with less sensitive responses to changes in dosage and pH, especially in acidic conditions. Meanwhile, ACH performed better at higher pH levels with half the dosage required, suggesting both coagulants can perform equally well under different optimal conditions.

Summary: This study tested and compared the separation performance of different membranes for treating oily wastewater. The XT and MT membranes showed the best performance with high oil removal rate. However, wetting occurred in the membrane distillation method, causing flux reduction. Therefore, a membrane surface modification technique is required to improve the anti-fouling and anti-wetting properties of the membranes.

Summary: Water-based muds (WBM) are commonly used in oil and gas wells drilling industry due to their eco-friendliness and cost-effectiveness. However, the hydration caused by the affinity of shale minerals to water from WBM leads to severe shale swelling issues, reducing the technical performance of WBM. In this study, graphene oxide (GO) was added to the drilling fluid formulation as an additive to improve drilling performance. The modified GO showed reduced fluid loss, improved rheology property, and enhanced thermal stability, making it a promising nano-additive for fluid loss control in drilling fluids.

However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
