Plastic wastes are generally not easily degradable under the action of environmental components. They very much resistant to microbial attack too. These non-biodegradable plastics accumulate over a longer period time on earth leading pollution. However, this may be avoided by using biodegradable polymers. Thus demand for preparation polymers has grown up. In recent years, researchers have devel...

The production of degradable packaging materials is a task that can be no longer postponed. Moreover, high amounts agricultural wastes are landfilled without any recycling. In this research, the possibility to formulate particulate composites made biopolymers filled with coffee waste acceptable physical and mechanical characteristics will degrade investigated. addition waste, by reducing reques...

Engineered skin substitutes (ESSs) have been reported to close full-thickness burn wounds but are subject to loss from mechanical shear due to their deficiencies in tensile strength and elasticity. Hypothetically, if the mechanical properties of ESS matched those of native skin, losses due to shear or fracture could be reduced. To consider modifications of the composition of ESS to improve homo...

BACKGROUND Petroleum polymers contribute to non-degradable waste materials and it would therefore be desirable to produce ecofriendly degradable materials. Biodegradation of polyhydroxybutyrate (PHB) in the presence of oligomer hydrolase and PHB depolymerase gave 3-hydroxybutyric acid which could be oxidized to acetyl acetate. Several bacteria and fungi can degrade PHB in the soil. RESULTS Bi...

A study was undertaken on lucerne (LUC), ryegrass (RG), kikuyu (KIK), soybean meal (SBM), wheat grain (WG) and meat and bone meal (MBM) to determine the effect of animal species (sheep versus cattle) on in sacco degradation of dry matter (DM) and protein. The approach of cubic smoothing splines ®tted as a linear mixed model was used for the analysis of degradability of DM and protein of feeds. ...

Biopolymer nanoparticles can be formed by heating globular protein/polysaccharide mixtures above the thermal denaturation temperature of the protein under pH conditions where the two biopolymers are weakly electrically attracted to each other. In this study, the influence of polysaccharide linear charge density on the formation and properties of these biopolymer nanoparticles was examined. Mixe...

A reactive oxygen species (ROS)-degradable scaffold is fabricated by crosslinking biocompatible, hydrolytically-degradable poly(ε-caprolactone) (PCL) with a ROS-degradable oligoproline peptide, KP7K. The ROS-mediated degradability triggers favorable host responses of the scaffold including improved cell infiltration and angiogenesis in vivo, indicating its unique advantages for tissue engineeri...

Extended life expectancy and medical development has led to an increased reliance on biomaterial implants and devices to support or restore human anatomy and function. However, the presence of an implanted biomaterial results in an increased susceptibility to infection. Due to the severity of the potential outcomes of biomaterial-associated infection, different strategies have been employed to ...

Two printing methods, extrusion and inkjet, are used to deposit tracks of PEDOT/PSS conducting polymer onto biopolymer films with a view to prepare implantable tissue mimics containing electronic devices. Extruded tracks offer lower printing resolution, but better electrical characteristics compared to inkjet printed tracks. The biopolymer–ink interaction results in narrower printed tracks comp...
