Carbonized cellulose catalyst support was prepared and decorated with 5 wt% Pd nanoparticles using an impregnation method. According to the SEM images, the carbonized cellulose catalyst support kept its original fibrous structure with an average diameter of 200 nm, owing to the carbonization of the cellulose fibers. The surface of the formed carbon fibers is richly coated by palladium with even coverage

Understanding the ultrastructure and chemical characterization of pulp fibers is highly important in utilizing wood as a raw material in a wide scope of applications, such as forest biomass-based biorefineries and low-cost renewable materials. The observation of the ultrastructure is not possible without advanced microscopy and spectroscopy techniques. Therefore, this study focuses on exploring the

Poly-Ether-Ether-Ketone (PEEK) is a structural biopolymer with various biomedical applications, from spinal cages to dental prosthetics. Due its high chemical stability combined with good mechanical strength, PEEK is considered to be one of the most successful bio-inert polymers ever developed. In this work, a mixture of PEEK and β-Si3N4 was used to produce a composite material which combined the mechanical

Balancing the performance, durability and safety requirements of automotive systems with the regulatory landscape in an environment of climate change has accelerated the search for sustainable fiber reinforced polymer composites for automobile structures. Glass fiber reinforced thermoplastic polymer composites (GFRP) are widely used in certain structures like front end modules and liftgate; However

Oxygen-functionalized porous carbon (PC-800) was fabricated through direct thermal treatment of biowaste under inert atmosphere. The PC-800 was systematically characterized and the results showed that the catalyst was extremely favorable for catalysis due to its high specific surface area (993 m2/g) and abundance active sites (ketonic groups). The results indicated that PC-800 can efficiently degrade

Self-polymerization of dopamine, in either an alkaline or an acidic environment, to form polydopamine is a material-independent surface coating technique, influencing almost all areas of material science and engineering. We demonstrated a simple, two-step method to prepare in-situ silver or silver-copper alloy nanoparticles on the surface of reduced graphene oxides, using polydopamine formed in an
