Article Abstract

Targeted at organic dye pollutants, a stable HOF was combined with an alginate (SA) hydrogel to enhance the affinity for cationic dyes. The as-obtained HOF@SA membrane (weight ratio: 1/1) shows a high adsorption capacity (729.21 mg g), adsorption selectivity and good recycling performance towards methylene blue.

Herein, we present a simple and novel method to prepare soybean protein isolate (SPI)-based hydrogels with good mechanical characteristics. First, SPI/DSA hydrogels were prepared using SPI and different M/G ratios (1:2, 1:1, and 2:1) of dialdehyde sodium alginate (DSA). Then, the hydrogels were immersed in CaCl2 solution to form SPI/DSA@Ca double network hydrogels.

Histological preparation paraffin embedding is the gold standard method for evaluating tissue structure and composition, whether it is originated from biopsy or engineered . Quite often, deformation and shrinkage occur during the histological preparation, which are difficult to predict and qualify. The present study investigates the morphometric changes in bioprinted hydrogels composed of alginate and gelatine, common tissue engineering materials, focusing on three morphologies: full slabs, porous slabs, and porous cubes.

Alternating 2D and 3D culture reduces cell size and extends the lifespan of placenta-derived mesenchymal stem cells.

Background: Mesenchymal stem cells (MSCs) hold great promise for treating a variety of human diseases; however, their clinical translation is hindered by challenges in large-scale expansion while preserving therapeutic potency and maintaining small cell size. Conventional 2D culture on rigid substrates induces MSC senescence and enlargement, compromising their function and biodistribution.

Methods: We present an alternating 2D/3D culture strategy that combines adherent monolayer expansion with transient spheroid formation to mitigate these limitations.

Study on Permeability and Flow Characteristics of Composite Thermosensitive Hydrogel and Its Fire Prevention and Extinguishment Performance.

This study focuses on the issues of poor fluidity, low penetration into residual coal, and suboptimal inhibition of coal spontaneous combustion associated with traditional coal mine gel fire retardants. The permeability and flow characteristics of a sodium alginate-based composite thermosensitive hydrogel, as well as its fire prevention and extinguishment performance, were investigated. The findings suggest that the thermosensitive hydrogel behaves as a pseudoplastic fluid at 40 °C and a yield-pseudoplastic fluid at 65 °C, exhibiting shear-thinning behavior with increasing shear rate.
