Sustainable Production of Cellulose-Based Hydrogels with
The copolymer chitosan-g-PAN product was then hydrolyzed to yield a novel smart hydrogel (H-chitoPAN) with superabsorbing properties. The influence of add-on values as well as temp. and time of hydrolysis of the initial chitosan-g-PAN on swelling behavior of the hydrogel was evaluated in water and various salt solns.

Application of Chitosan in Fresh and Minimally Processed
After 9 days of storage at 10°C, decay percentages for chitosan-coated strawberries (0.5, 1.0, and 1.5 g/100 mL) were 25.3, 15.7, and 6.9%, respectively, while in the control berries the incidence was 95.2%. The effect of chitosan in reducing microbial growth was more evident for longer storage periods and at higher storage temperature.
THE USE OF CHITOSAN AS A COATING MATERIAL . The effect of chitosan (1.0 g L−1) + MAP was compared with MAP (control), and was effective in preventing decay, browning and retaining the
Microfungal spores (Ustilago maydis and U. digitariae
The images of the plain chitosan microbeads and the U. digitariae and U. maydis spores immobilised chitosan microcapsules at different magnification are presented in Fig. 1.Plain chitosan microbeads had smoother surface morphology when compared with the microcapsules (Fig. 1a–c).The microcapsules with U. digitariae spores had rougher surface than the ones with U. maydis (Fig. 1d–i).
Sodium hyaluronate is smaller than hyaluronic acid and is able to move more freely into the deeper layers of the skin. This is an advantage since sodium hyaluronate is a powerful humectant that attracts and holds on to water, making it the ultimate skin moisturizer.

Consumer awareness about the damages that plastic packaging waste cause to the environment, coupled with bio-economy and circular economy policies, are pushing plastic packaging versus the use of bio-based and biodegradable materials. In this contest, even cosmetic packaging is looking for sustainable solutions, and research is focusing on modifying bio-based and biodegradable polymers to meet

Described is gel, representing sparsely-cross-linked chitosan and polyanionic hydrocolloid polymer, which has 2-3 linkages of copolymers per chitosan molecule, and distributed in it auxiliary substances. As polyanionic hydrocolloid, used is suspension of sucralfate or polyalginic acid particles, containing 0.01-15 wt % of stabiliser.

- Why is activated carbon used in water and wastewater treatment?
- The activation process enhances the porosity within the carbon, making the carbon effective in adsorbing small molecular compounds . There are two principal types of activated carbon used in water and wastewater treatment processes, which differ in their morphology and particle size.
- Are activated carbons effective in removing pollutants from aqueous solutions?
- Activated carbons are proven to be effective in the removal of various pollutants from aqueous solutions, including dyes, pharmaceutical personal care products (PPCPs), heavy metals, and organic pollutants. Dyes are one of the heavy pollutants which affect water bodies, due to the usage of dyes in paints, clothing, paper products, and plastics.
- What is activated carbon used for?
- Due to large surface area and pore volume of the activated carbon, it can be employed in the removal of color, odor, and taste from water and wastewater. It can also be applicable for the recovery of natural gas and air purification in inhabited spaces, such as chemical industries, and it can act as catalyst and catalyst support material [1, 2].
- Why should you buy activated carbon products?
- JSC «Sorbent» offers a wide range of modern, high-quality products that effectively protect human health and guarantee environmental protection. They produce reliable respiratory protection products and more than 40 trademarks of activated carbon. The company successfully implements water treatment projects.
