Summary: A material called Cell/PANI-PAMPSA, made from cellulose fibers, aniline, and PAMPSA, was synthesized in a simple way. Various techniques were used to investigate its morphology, mechanical properties, thermal stability, and electrical conductivity. The results showed that the Cell/PANI-PAMPSA composite exhibited excellent features compared to the Cell/PANI material. This study explored novel device functions and wearable applications for this material, such as humidity sensors and disposable biomedical sensors for immediate diagnostic services.

Summary: An eco-friendly superabsorbent polymer (SAP) was prepared by grafting 2-acrylamido-2-methyl-1-propane sulfonic acid onto microcrystalline cellulose. The SAP showed high water absorption capacities in different solutions and could reach water absorption equilibrium quickly. It also exhibited high acid and alkali resistance, making it suitable for extreme conditions. The synthesized SAP can be used to improve plant growth and survival under drought and saline alkali conditions.

Summary: The gamma radiation technique is used to prepare pure hydrogels, which are essential in various fields. This study focuses on the preparation and characterization of DMAA-AMPSA superabsorbent hydrogel using gamma radiation and determining the optimal dose. The equilibrium swelling increases with increasing radiation dose, reaching a maximum of 26,324.9% at 10 kGy. The characterization techniques confirm the formation of the co-polymer and the thermal stability of the gel.

Summary: This article presents a straightforward method for preparing highly hydrophilic ultrafiltration polyaniline poly(2-acrylamido-2-methyl-1-propanesulfonic acid) membranes (PANI PAMPSA) and describes their application in the fractionation of phytosterols and proteins from fruit juice. The results show that the PANI PAMPSA membrane has comparable protein separation efficiency to a commercial membrane but performs slightly worse in the rejection of phytosterols. However, the PANI PAMPSA membrane is more susceptible to fouling, although it can achieve a good cleaning efficiency after multiple fouling-cleaning cycles.

Summary: This study synthesized CuO nanoparticles decorated poly(2-acrylamido-2-methyl-1-propanesulfonic acid)/chitosan composite material for the uptake of doxycycline from water. The composite material showed a high removal efficiency of 98.84% under optimal conditions. Experimental data fitting revealed that the Langmuir isotherm and pseudo-second-order kinetic models best described the adsorption process.

Summary: In enhancing oil recovery, new water-soluble polymers are developed to replace the toxic acrylamide (ACR) monomer. Acrylic acid (AA) and 2-acrylamido-2-methylamido-2-methyl-1-propanesulfonic acid (AMPS) are commonly used replacements, but they also exhibit cytotoxicity, DNA damage, cell cycle arrest, and induction of apoptosis. AA and AMPS have lower acute toxicity than ACR, but they are not entirely toxic-free. It is important to focus on the toxicity of AA and ACR to protect occupational health.

Summary: The water ecosystem is contaminated by various pollutants due to industrialization and urbanization. This study examines a hydrogel-based dye adsorbent and photocatalyst system for the removal of dye pollutants. The results show that the hydrogel has a higher adsorption capacity for cationic dyes compared to anionic dyes, and grafting polymers onto chitosan significantly enhances dye adsorption. The molar ratio of the grafting monomers also affects the adsorption capacity. In addition, in situ synthesized zinc oxide particles enhance the recovery and purification of the photocatalyst. Overall, this hydrogel composite is an effective dual-functional material for dye adsorption and photodegradation in wastewater.

Summary: Polyampholyte nanogels based on NIPAM, APTAC, and AMPS were synthesized and their temperature and salt-responsive properties were studied. The nanogels with charge balance showed the highest volume phase transition temperature at higher salt concentrations, while the same parameter for the charge-imbalanced nanogels decreased significantly at higher salt concentrations. The particle size distribution of the nanogels tended to become narrower and monomodal at higher temperatures and ionic strengths.

Summary: The synthesis of novel superabsorbent polymers (SAPs) based on itaconic acid (IA) and 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) improves the absorption performance of SAP, particularly in aqueous salt solutions. The introduction of AMPS enhances the salt-resistant properties of SAP and increases the centrifugation retention capacity (CRC) and absorbency under load (AUL) of the polymer.

Summary: This study characterizes the coacervates of the Poly (2-acrylamido-2-methyl-1-propanesulfonic acid-co-acrylonitrile) / beta-Galactosidase complex using various techniques and provides insights into their formation and properties. The use of turbidimetry, light scattering, microscopy, and fractal analysis allows for the observation of the structure, size distribution, and spatial heterogeneity of the coacervate droplets and fractal solid precipitates. Additionally, a new methodology for determining the radius of gyration of the droplets is presented. The findings suggest that aging improves the stability of the swollen condensates and that the growth of coacervate droplets is influenced by electrostatic interactions and diffusion-limited cluster aggregation.

Summary: A series of hybrid proton exchange membranes was synthesized by in situ polymerization of PMPS with SPEES, demonstrating enhanced ionic conductivity. The optimized water uptake, swelling ratio, and conductivity were attributed to a less ordered arrangement of polymer chains with a high density of functional groups facilitating ionic transport. SP-PMPS-03 exhibited excellent chemical and thermal stability for electrochemical applications.
