For the purpose of fabricating electrically conductive composites via fused filament fabrication (FFF) technique whose properties were compared with injection-moulded properties, poly(lactic acid) (PLA) and polycaprolactone (PCL) mixed different contents graphene nanoplatelets (GNP). The wettability, morphological, rheological, thermal, mechanical, electrical 3D-printed samples investigated. microstructural images showed selective localization GNPs in PCL nodules that are dispersed PLA...

Despite the multitude of therapeutic agents available to treat prostate cancer (PC), there are still no effective and safe measures tumor. It remains a challenge develop simple approach target PC with specific antibodies. In our study, D2B monoclonal antibodies against prostate-specific membrane antigen (PSMA) were used. We investigated functionalization gold nanoparticles (AuNPs) generate favorable physicochemical biological properties that mediate binding PC. For this purpose, AuNPs size...

Increasing the flame retardancy of lignocellulosic materials such as Miscanthus × giganteus can effectively enable their wide use. This study examines fireproofing process particles using an eco-friendly by grafting phytic acid and urea in aqueous solution. underwent a steam explosion step before being grafted. Fireproof binderless particle panels were manufactured from miscanthus with or without adding olive pomace hot-pressing. The effect and/or flame-retardant treatment on morphology,...

The effect of the severity an organosolv treatment Miscanthus x giganteus on antioxidant capacity obtained lignin was studied. Four lignins extracted with different conditions were chosen and tested. Results using methyl linoleate method have shown a correlation between oxygen uptake index combined severity. It found that at higher pre-treatment phenolic hydroxyl content, lower aliphatic molecular weight polydispersity has highest capacity.

Recycling olive waste, a major by-product of the oil industry, presents significant environmental and economic benefits. This study explores potential waste (OW) by-products, specifically their individual components such as stones (OS), oily pomace (OS) oil-free (OF), sustainable alternatives to wood in eco-friendly composite materials, alongside other residues miscanthus, spent mushroom substrate recycled textile waste. Composite panels were produced with densities ranging from 685 907...

Lignin was extracted from Miscanthus × giganteus using two procedures: an aqueous-ethanol organosolv treatment and a two-step process involving dilute acid pre-soaking step followed by treatment. The lignin subjected to comprehensive structural characterization 13C MALDI-TOF MS used for the formulation of green wood adhesive prepared with 100% natural resins. best composed 60% mimosa tannin 40% glyoxalated 1-step This formulation, when applied wooden test panels yielded good internal bond...

ABSTRACT The main objective of this study is devoted to the development new insulating and ignifuged miscanthus fibers (Mf)/recycled textile (RTf) reinforced biocomposites (BCs) using chitosan as polysaccharide‐based binder aluminum trihydroxide (ATH) fillers while focusing on fire behavior. To achieve goal, a preliminary was carried out flame retarded chitosan‐based films with various ATH‐filler ratios (20, 33, 50, 60 wt %). ATG pyrolysis‐combustion flow calorimeter analysis showed...

In this study, a representative set of thermally thin materials including various lignocellulosic and synthetic fabrics, dense wood, polypropylene sheets were tested using cone calorimeter at different heat fluxes. Time-to-ignition, critical flux, peak release rate (pHRR) the main parameters considered. It appears that flammability is firstly monitored by sample weight. Especially, while burning thermally-thin does never reach steady state in calorimeter, their pHRR to be mainly driven fire...
