Enhancing rice straw compost with an amino acid-derived ionic liquid as additive
- To improve the quality of lignocellulose compost, the effect of a potential new-generation additive—amino acid-derived ionic liquid—on a compost pile comprising 50% rice straw was studied...
Impact of inoculation and turning for full-scale composting on core bacterial community and their co-occurrence compared by network analysis
- Window composting with inoculation or frequent turning is a superior way to improve traditional composting efficiency. However, the relationship between the innocent treatment in composting with...
Machine learning-aided causal inference for unraveling chemical dispersant and salinity effects on crude oil biodegradation
- Chemical dispersants have been widely applied to tackle oil spills, but their effects on oil biodegradation in global aquatic systems with different salinities are not well understood. Here, both...
Enhancing the thermostability, UV shielding and antimicrobial activity of transparent chitosan film by carbon quantum dots containing N/P
- The chitosan (CS) transparent film has attracted much attention in food and medicine packaging areas due to their biodegradability and good availability. A novel carbon quantum dots compound...
Degradable collagen/sodium alginate/polyvinyl butyral high barrier coating with water/oil-resistant in a facile and effective approach
- Degradable bio-based materials have been widely considered as functional coatings, however, it is a great challenge to fabricate biodegradable coatings with high barrier, water- and oil-...
Relations between starch fine molecular structures with gelatinization property under different moisture content
- Although gelatinization property has been intensively investigated with its relation to starch structures, how a combination of starch molecular structures and moisture content affect the...
Optimized hydration dynamics in mucoadhesive xanthan-based trilayer vaginal films for the controlled release of tenofovir
- Karaya gum, pectin and xanthan gum have been tested as candidates for manufacturing mucoadhesive trilayer films containing ethylcellulose and chitosan for the vaginal administration of the...
Trends in “green” and novel methods of pectin modification - A review
- Modification of hydrocolloids to alter their functional properties using chemical methods is well documented in the literature. There has been a recent trend of adopting eco-friendly and...
A fast method to measure the degree of oxidation of dialdehyde celluloses using multivariate calibration and infrared spectroscopy
- The properties of dialdehyde celluloses, which are usually generated by periodate oxidation, are highly dependent on the aldehyde content, i.e. the degree of oxidation (DO). Thus far, the...
A pulp foam with highly improved physical strength, fire-resistance and antibiosis by incorporation of chitosan and CPAM
- Bio-inspired borate cross-linked pulp foam (PF) with high porosity and low density can be widely used in many fields. However, PF is flammable, and lack of mechanical strength and antibacterial...
Phytotoxicity assessment of biodegradable and non-biodegradable plastics using seed germination and early growth tests
- Global production of plastics remains at the high level despite the SARS-Cov-2 pandemic. These are primarily petroleum-derived plastics but the contribution of bio-based plastics estimated at the...
Biodegradation of ?-cyhalothrin through cell surface display of bacterial carboxylesterase
- Pyrethroids are the third widespread used insecticides globally which have been extensively applied in agricultural or household environments. Due to continuous applications, pyrethroids have been...
Enhanced water flux and bacterial resistance in cellulose acetate membranes with quaternary ammoniumpropylated polysilsesquioxane
- An enhanced water flux and anti-fouling nanocomposite ultrafiltration membrane based on quaternary ammoniumpropylated polysilsesquioxane (QAPS)/cellulose acetate ([email protected]) was...
Mussel-inspired adhesive bilayer hydrogels for bacteria-infected wound healing via NIR-enhanced nanozyme therapy
- Preventing bacterial infection in situ and accelerating skin generation simultaneously are essentially important for wound healing. Herein, a mussel-inspired Ag nanozyme-based bilayer hydrogel is...
Mg.ATP-decorated ultrafine magnetic nanofibers: A bone scaffold with high osteogenic and antibacterial properties in the presence of an electromagnetic field
- In this study, ultrafine magnetic nanofibers were developed for bone regeneration purposes. Nanofibers were acquired by electrospinning using a two-component nanofiber matrix (CP: chitosan (Cs)...
A copper organic phosphonate functionalizing boron nitride nanosheet for PVA film with excellent flame retardancy and improved thermal conductive property
- With the rapid development of fifth-generation (5G) communication, the polymeric films with satisfactory flame retardancy and high thermal conductivity have become one of the hot topics in...
Hierarchically porous biochar derived from orthometric integration of wooden and bacterial celluloses for high-performance electromagnetic wave absorption
08/02/2022 - Inspired by the natural growth of wooden cellulose (WC) and bacterial cellulose (BC), we integrated the two categories of cellulosic materials by static fermentation. BC networks created in plane...
