TL;DR: Biodegradable and non-retrogradable starch-glycerol based films were obtained using citric acid as crosslinking agent at 75°C and remained amorphous for at least 45 days as a result of the network formed by the CA that avoided starch retrogradation and maintained the degradability in compost.

TL;DR: The potential of this new slow-release fertilizer system for improving the effectiveness of fertilizers is demonstrated, and in particular, those with potato starch-SAP coating exhibited a steady release behavior for a period longer than 96h.

TL;DR: Although the incorporation of thermoplastic chitosan caused a decrease in both tensile strength and stiffness, films with better extensibility and thermal stability were produced.

TL;DR: Pb(II) removal mechanisms of SA-CMC, including physical, chemical, and electrostatic adsorptions, were discussed based on microstructure analysis and adsorption kinetics and it was demonstrated that the lead ion removal efficiency of SA -CMC was significantly higher than that of conventional adsorbents.

TL;DR: The NC obtained from MCC can be used as a reinforcing agent for the preparation of biodegradable composites films for their potential use in the development of biodesgradable food packaging materials.

TL;DR: The prepared nano-dimensional cellulose demonstrated a network-like structure with higher crystallinity than that of untreated fiber, and possessed of good thermal stability which is suitable for nanocomposite material.

TL;DR: The plasticizing effect of yerba mate extract makes it an attractive additive for starch films which will be used as packaging or coating; and its contribution to an earlier biodegradability will contribute to waste reduction.

TL;DR: In this work, nanocellulose was extracted from bleached corncob residue (CCR), an underutilized ligno cellulose waste from furfural industry, using four different methods and the intensive pulp refining led to the CNFs with the longest length and the thickest diameter.

TL;DR: The aim of this review is to discuss about the applicability in biomedicine by demonstrating a variety of forms of this biopolymer highlighting in detail some qualities of bacterial cellulose.

TL;DR: This review focuses on the application of BC-based composites for microbial control, wound dressing, cardiovascular, ophthalmic, skeletal, and endodontics systems and applications in controlled drug delivery, biosensors/bioanalysis, immobilization of enzymes and cells, stem cell therapy and skin tissue repair.

TL;DR: Results suggest that ZnO-BC films may be used as controlled release antimicrobial food active packaging and reduced water vapor permeability and moisture absorption of BC films.

TL;DR: The present review highlights recent progress in the field of the application of cellulose nanofibres as additives in papermaking and revises the mechanisms behind CNF reinforcing effect on paper and the effect of chemically modified CNF as additives.

TL;DR: The prepared bionanocomposites displayed good antibacterial activity against gram positive, gram negative, and gram negative bacteria and fungi, and the packaging films assisted in increasing the shelf life of white soft cheese.

TL;DR: Box-Behnken design was used to study the effect of irradiation time, microwave power and pH on the yield and degree of esterification (DE) of pectin, and it showed that the optimum conditions for the highest yield of pECTin were obtained at pH of 1.50.
