Article Abstract
The potential of nanocomposite membranes (NCMs) prepared by the sodium alginate polymer and embedded with synthesized zeolitic imidazole framework-8 (ZIF-8) as fillers having microporous structure in the application of separation of gaseous mixture generated by the process of methane reforming was assessed. ZIF-8 crystals were created through hydrothermal synthesis, with sizes varying from 50 to 70 nm. NCMs were prepared with a 15% filler loading, i.e., synthesized ZIF-8. NCMs (ZIF-8) having H permeability of 28 Barrer and H/CH selectivity of 125 outperformed neat polymer membranes in terms of separation performance at ambient temperature and 4 kg/cm pressure. The purity of H increased to as high as 95% among the measured values. The NCMs did not, however, outperform a neat polymer membrane in terms of their ability to separate mixtures of gases. Moreover, the combination of ZIF-8 as a filler with sodium alginate was new and had not been reported previously. As a result, it is worthwhile to investigate.

At present, flexible sensors are a hot spot in research and experimental development, but the research on flexible sensors that can be used for human motion monitoring still needs to be deepened. In this work, the green material cellulose acetate (CA) was used as the matrix material, the film was made by electrospinning, crushed by a cell grinder and sodium alginate (SA) was added to promote the uniform dispersion of nanofibers in water, and then methyltrimethoxysilane (MTMS) and MXene nanosheet dispersion were added to make it hydrophobic and good conductivity, and the aerogel precursor solution was prepared, and then the CA/SA/MTMS/MXene aerogel with directional holes was prepared by directional freeze-drying. As a flexible sensor material, it can be used for human wear, monitoring the electrical signals generated by the movement of human joints and other parts, and can still maintain a current of about 0.

Bioprotective LAB3 cells that produce bacteriocin-like substances were entrapped in 4% (w/w) sodium alginate matrices, either with or without 10% (w/w) sodium caseinate. The effects of bead formulation-alginate alone or combined with caseinate, with or without the addition of 20% (w/w) MRS broth or M17 broth-on the culturability of LAB3 cells within the beads and their anti activity were assessed over 12 days of storage at 30 °C in closed bottles. Calcium-alginate-caseinate beads supplemented with MRS broth proved most effective in preserving both culturability and anti- activity.

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.

Introduction: Burn wounds are painful injuries that demand immediate and effective management. Conventional wound care solutions often have limitations, such as discomfort during application or removal and potential damage to healing tissue. Therefore, developing novel wound dressings that support biological processes and promote wound healing is highly beneficial.
