Summary: Metal-organic frameworks (MOFs) are porous crystalline materials composed of metal and organic material, with properties such as tunability, large surface area, and high porosity. They have various applications in environmental protection, biosensors, regenerative medicine, medical engineering, cell therapy, catalysts, and drug delivery. MOF-based asymmetric membranes improve stability and specificity, while conjugated membranes increase the area of functional groups, making them attractive for drug and biosensor fabrication. MOF-assisted membranes provide a platform with different properties and characteristics for biomedical applications. The latest version of MOF materials/membranes has potential applications in medical engineering, cell therapy, drug delivery, and regenerative medicine.

Summary: The use of antibiotics and dyes has caused severe water pollution and health risks, necessitating their elimination from water sources. Adsorption and photodegradation are economical, simple, and reusable methods for removing harmful water contaminants. Metal-organic frameworks (MOFs), such as ZIF-8 and ZIF-67, are effective adsorbents and photocatalysts due to their high porosity, adjustability, and crystal structure. This article reviews the design and synthesis methods of ZIF-8 and ZIF-67 composites and discusses their role as adsorbents and photocatalysts in wastewater pollution removal, aiming to provide insights for the development of highly effective ZIF-8/67-based materials.

Summary: The construction of a p-n heterojunction photocatalyst successfully overcomes the low photo-catalytic activity caused by rapid charge recombination and limited photo-response range. In this study, an interlayer of expanded MoS2 coupled with Bi2WO6 (BW-IEM) photocatalyst was synthesized, achieving a Methylene Blue (MB) removal rate of up to 97% (5.18 x10-2 min-1) under the irradiation of low power 1W LED white light. The outstanding photocatalytic performance of the p-n heterojunctions BW-IEM photocatalyst is attributed to the enhancement of light harvesting, improvement in the separation of charge carriers, and coexistence of oxygen vacancy. The main reactive oxygen species (ROS) responsible for the photo-degradation of MB were center dot Oz radicals and center dot OH. This work provides a new strategy for the potential IEM photocatalyst as a matrix in a p-n heterojunction composite.

Summary: This study investigates the effects of silica on polyacrylamide (PAM) using comprehensive rheological data. Modified PAM shows distinct chemical structures compared to bare PAM, but both are hydrophilic fluids. The rheological performance of all modified PAM shows an undulated trend for all concentrations of silica and selected temperatures, but all modified PAM perform better than bare PAM. Therefore, a formulation of 0.5 wt% silica is promising for PAM modification, even simulating the performance of bored pile drilling. In terms of thermal stability, the rheological performance of bare PAM and modified PAM shows better results at 60 and 40°C, respectively.
