Summary: An efficient method for the separation and recovery of V(V) from the pressure acid leaching solution of vanadium shale was developed using the iminodiacetic acid chelating resin CH-90. By investigating the mechanism of V(V) adsorption and selective separation between V(V) and impurities, it was found that the resin preferentially adsorbed H2V10O284- during the adsorption process. The CH-90 resin contributed to simultaneously separating V(V) in the form of H2V10O284- and VO2+ from a complex sulfuric acid leaching system at low pH.

Summary: This study aimed to modify the polypropylene (PP) surface by grafting with acrylic acid (AA) monomer, using styrene (ST) and benzoyl peroxide (BPO) as comonomer and initiator, respectively, in toluene solution, for potential application as an automatically latex-coagulating cup. The presence of ST comonomer significantly improved the grafting percentage of AA onto PP sheets (PP-g-P(ST-co-AA)), as well as its ion exchange capacity. The grafted PP with ST/AA monomers exhibited high coagulum performance and coagulation rate of natural rubber latex (NRL).

Summary: This research investigated the removal of boron and arsenic from geothermal water using newly synthesized gel-like chelating resins. The results showed that the novel resins were able to reduce boron and arsenic concentrations in geothermal water below permissible levels for agricultural irrigation and drinking water. The optimal resin concentration for boron removal was determined to be 2 g/L, while for arsenic removal, a resin concentration of 8 g/L was needed for 94% removal using the novel resins compared to 32 g/L for commercially available resin. Column performance characteristics of the resins were also studied and compared to a commercially available resin.

Summary: This study investigated the adsorption characteristics of chitooligosaccharides on ion-exchange resin and found that the adsorption equilibrium followed the Langmuir model, with adsorption capacity decreasing with increasing degree of polymerization. The adsorption kinetics were well described by the pseudo-second-order kinetic model. Liquid-film diffusion and intra-particle diffusion were identified as the rate-limiting steps for adsorption. Thermodynamic analysis revealed that the adsorption of chitooligosaccharides on HX-7 resin was spontaneous and feasible, with higher polymerization degrees leading to stronger interaction forces and more favorable adsorption.

Summary: In this study, two dittmarite-type magnesium phosphates, KMP and NMP, were synthesized and demonstrated remarkable adsorption capacities for Cs+. However, their ability to adsorb Cs+ from environments with high divalent ion concentrations is limited. After adsorption, KMP and NMP were structurally transformed into CsMP, with two different stacking structures depending on the solution's pH. The high adsorption capacities of KMP and NMP can reduce the volume of radioactive waste for disposal.

Summary: The polymer composite material PVA/BC/CaCO3 was developed for selective adsorption of toxic heavy metal ions such as Cd(II), Cu(II), and Pb(II) from solution. The adsorption kinetics data fit the pseudo-first-order kinetics model, while the thermodynamic adsorption data fit the Langmuir model. The maximum adsorption capacities for Cu(II), Pb(II), and Cd(II) were found to be 57.1, 513.6, and 238.6 mg/g, respectively, at 40 degrees C. This adsorbent also showed high recyclability, indicating its potential in removing heavy metal ions from contaminated solutions.

Summary: This review discusses the dynamic interplay between extracellular matrix with anisotropic structure and biological cells, leading to the development of actuation-responsive biomaterials. Liquid crystalline elastomers (LCEs) are stimuli responsive polymers that can exhibit reversible orientational order due to the attachment of highly anisotropic mesogenic units to amorphous elastomeric chains. The review briefly explains the structures and synthesis methods of LCEs, highlighting their biochemical and biomechanical features from a molecular perspective.

Summary: The field of nanotechnology has opened up new possibilities for drug delivery systems, reducing the side effects of conventional chemotherapy. ZIF-8, a promising porous material, tends to aggregate in water, limiting its usefulness. By incorporating ZIF-8 into hydrogels made of gelatin and carboxymethylcellulose, we improved their mechanical strength and stability without aggregation. We used double emulsions with the hydrogels and biological macromolecules to create drug carriers with precise control over drug release. Characterization techniques confirmed the stability of the nanocarriers, which showed cytotoxicity against cancer cells and potential for further investigation.

Summary: Endowing wound dressings with drug delivery capability is an effective strategy for localized transfer of medicinal compounds to damaged skin layers. This study designed and fabricated a wound dressing composed of polyamide 6, hyaluronic acid, and curcumin-loaded halloysite nanotubes (PA6/HA/HNT@Cur) for wound healing applications. The platform exhibited desirable physicochemical properties, antibacterial and antioxidation activities, as well as good cell compatibility. In vivo evaluation showed that the nanocomposite mat significantly reduced wound size after 14 days. This study provides a swift and straightforward method for developing wound dressings in clinical settings.
