Summary: Agriculture is affected by water scarcity and nutrient deficiency, and it also contributes to these issues. Using biodegradable hydrogels as soil conditioners can improve irrigation efficiency, reduce the need for fertilizers, and combat pathogens. This study aimed to create and characterize Sodium Alginate-g-acrylamide/acrylic Acid hydrogels using electron beam irradiation, and investigate their potential as soil conditioners through absorption and release experiments. The hydrogels were obtained through irradiation using a linear accelerator and their physical, chemical, structural, and morphological characteristics were analyzed. Several experiments were performed to test the absorption and release of different nutrient solutions.

Summary: Poly(N-isopropylacrylamide) (P(NIPAAm)) hydrogels crosslinked with biodegradable poly (beta-amino ester) (PBAE) showed higher crosslinking degrees and compressive strength and lower swelling ratios compared to conventional N,N'-methylene bisacrylamide (MBA)-crosslinked hydrogel. The controlled release of KNO3 was achieved with the N/T5/1 sample, which demonstrated the most controlled release with 66.9% after 18 days in soil. The hydrogel with a porosity of 71.65% and crosslinking degree of 2.85 x 10(-5) mol cm(-3) showed promising properties for agricultural applications.

Summary: Hydrogels with tailor-made swelling-shrinkable properties have gained significant attention in the biomedical field. While highly swelling hydrogels are widely used in wound healing, tissue regeneration, and drug delivery, non-swelling hydrogels play important roles in tissue adhesives, soft-tissue wound healing, and bioelectronics. The negative swelling behavior of hydrogels can be utilized for noninvasive wound closure and drug release. However, there is a lack of a comprehensive review on the construction and biomedical applications of hydrogels based on their swelling-shrinkable properties. This review aims to summarize the strategies employed and provide a better understanding of the current progress and future challenges in this field.

Summary: Biodegradable synthetic hydrogels have shown promise for tissue engineering and drug/cell delivery applications, but successful implementation requires a precise understanding of degradation response. This work presents a thermodynamically-consistent framework and constitutive models for simulating degradation-induced swelling in hydrogels, validated against experimental data. The models could be beneficial for designing hydrogels with controlled degradation behavior.

Summary: Polyurethane hydrogels are widely used in various fields due to their durability, flexibility, and biocompatibility. In this study, polyurethane-based hydrogels were prepared using polyethylene glycol and a novel lactose monomer. It was found that the swelling of the hydrogels was driven by the hydrophilicity of the lactose units. Sulfation of the lactose rings resulted in high-swelling polyelectrolyte hydrogels. Furthermore, the effects of PEG molecular weight, degree of crosslinking, and sulfation on the swelling of the hydrogels were investigated.
