Synthesis of Acetobacter xylinum Bacterial Cellulose Aerogels and Their Effect on the Selected Properties

Scientists created a special lightweight foam-like material made from bacterial cellulose that could be used in wound dressings, insulation, and water filtration. The material was made sustainably using just tea, sugar, and bacteria—no harmful chemicals needed. Different freezing methods were tested to create the best possible structure, with liquid nitrogen freezing producing the most porous and uniform results. The material showed excellent insulation properties and is biodegradable, making it an environmentally friendly alternative to synthetic foams.

Processes of Obtaining Nanostructured Materials with a Hierarchical Porous Structure on the Example of Alginate Aerogels

Scientists created lightweight, sponge-like materials called aerogels made from alginate (a substance derived from seaweed) with special internal structures. They tested three different techniques to create these structures: using soap-like surfactants, using a plant protein called zein, and using pressurized carbon dioxide. Each method produced materials with different pore sizes and characteristics, making them suitable for different medical applications like delivering medications slowly or growing cells for tissue repair.
