Summary: A reactive blending strategy was proposed to develop a thermoplastic-thermoset blend with enhanced compatibility based on dynamic covalent chemistry. Polybutylene terephthalate (PBT) and polymerized epoxy vitrimer were melt blended and the bond exchange facilitated the grafting of PBT and epoxy vitrimer chains, resulting in improved interfacial compatibility and thermal stability. The obtained blend achieved a balance between the strength and stretchability of PBT and epoxy vitrimer, leading to enhanced toughness.

Summary: Surfactant blends show promising experimental performance in recovering remaining crude oil in carbonate reservoirs. A blend of dioctyl sulfosuccinate sodium (AOT) and polyoxyethylene(8) octyl ether carboxylic acid (Akypo LF2) in synthetic sea water (SSW) achieved low interfacial tension and moderate additional oil recovery. Adding the ionic liquid 1-dodecyl-3-methylimidazolium bromide ([C(12)mim]Br) improved the surface activity and significantly increased the additional oil recovery in the blend.

Summary: In this study, starch/polybutylene adipate terephthalate (PBAT) composite films with high starch content were prepared using cassava starch, benzophenone (BP), degradable PBAT, and citric acid as film-forming substrate, photosensitizer, toughening material, and solvent. The results showed that the composite films exhibited robust tensile strength (9.90 MPa), decent elongation at break (500.05%), and excellent shape memory property, thanks to the excellent performance of starch and PBAT. Additionally, PBAT rendered the starch-based films hydrophobic and improved their mechanical properties, meeting the requirements of thermal shrinkage films subjected to large strains.

Summary: There is a global trend towards substituting petrochemical-based polymers with biopolymers due to strong public concerns about environmental protection and potential energy crisis. Polybutylene succinate (PBS) has drawn interest as a biobased and biodegradable polymer, but its high flammability poses a major obstacle. Current research focuses on enhancing the flame retardancy of PBS through approaches such as inorganic particles, lignin, and intumescent flame retardant systems.

Summary: This study investigated the influence of polybutylene succinate (PBS) content on the physical, thermal, mechanical, and chemical properties of polylactic acid (PLA)/PBS composite fibers. The addition of PBS affected the fiber size distribution and surface smoothness. The results of DSC and X-ray diffraction analysis showed that PBS addition decreased the crystallization temperature and increased the crystallinity of PLA. Furthermore, adding PBS increased the tensile properties but significantly decreased the elongation at break.

Summary: The blooming of the world's human population and the transition of the human diet into a more westernized, high-protein diet has accelerated the production of slaughterhouse wastewater (SWW) as the number of meat processing plants (MPP) has increased in the past few decades. Conventional treatment processes (CTP) used in treating SWW, such as anaerobic processes, membrane processes, and electrocoagulation, have significant limitations, such as low treatment efficiency, tendency to foul, and high energy consumption, respectively. While advanced oxidation processes (AOPs) appear promising in replacing the former, they lack economic feasibility when used as a single process. In this paper, the limitations and disadvantages of the CTPs used in treating SWW influents are evaluated. The idea of utilising AOPs as a complementary step rather than a single process is also discussed. The review paper further explores the variability of different AOPs, such as Fenton, Electro-Fenton, Sono-Fenton, etc., and their respective strengths and weaknesses in counteracting the limitations of CTPs. The idea of incorporating resource recovery into wastewater treatment is also discussed towards the end of the paper as a means of generating additional revenue for the industry players to compensate for the high operation and maintenance costs of SWW treatment. The integration of a new-generation treatment process such as AOP into CTP while being able to carry out resource recovery is a future hurdle that must be overcome by scientists in order to produce a versatile, powerful, sustainable, yet financially feasible and operationally pragmatic treatment system.
