In this study, an innovative and scalable strategy is developed to valorize vegetable wastes as valuable cost-effective natural antioxidant resources in the development of CO2-based biocomposites. The dried stems (parsley spinach) are firstly micronized then incorporated into a CO2-derived poly(propylene carbonate) (PPC) polymer matrix by hot compression molding technique. waste microparticles ...

There is a groundswell of interest in applying phototrophic microorganisms, specifically microalgae and cyanobacteria, for biotechnology ecosystem service applications. However, there are inherent challenges associated with conventional routes to their deployment (using ponds, raceways photobioreactors) which synonymous suspension cultivation techniques. Cultivation as biofilms partly ameliorat...

Chitosan/lignin-containing cellulose nanofibrils (CS/LCNF) biocomposites were prepared by a facile and green method that combined hydrothermal pretreatment, mechanical fibrillation, dry casting. LCNFs isolated from switchgrass with various lignin contents, their effects on the transparency, micromorphology, properties, interfacial compatibility, thermal stability, surface wettability, barrier p...

Abstract Urban development and the construction industry account for a considerable proportion of global carbon dioxide (CO 2 ) emissions. Emerging biological materials, such as those proposed in this paper, seek to utilize metabolic functions living microorganisms reduce some negative impacts humans on environment. The material explorations demonstrated paper propose photosynthetic capture tex...

Environmental concerns have led to a rapid growing interest in replacing traditional petroleum-based technology with more green alternatives. Cellulose, one of the main components in plants, is a biodegradable and renewable recourse. The use of cellulose fibers, instead of traditional fibers such as glass and carbon, offers a way to make more environmental friendly biocomposites. By replacing t...

BACKGROUND AND AIMS Despite the fact that implants are sterilized, antiseptic techniques are applied and systemic antibiotics are routinely administered prior to and after craniofacial surgery, infection rates between 3% and 40% are still reported for alloplastic implants, urging for implant removal. The present study focuses on the development of a fiber-reinforced composite (FRC) implant for ...

The study focuses on structure-properties relationships in thermoplastic cassava starch (TPS) based biocomposites comprising 5–20 wt% of untreated and treated rice husk (RH). Alkaline treatment with 11% w/v NaOH removed the hemicellulose layer RH as confirmed by Fourier-transform infrared spectroscopy (FTIR) thermogravimetric analysis (TGA), resulted a larger population –OH groups exposing fibr...
