A stable water-based suspension containing chitin nanofibrils (CN), complexed with nanolignin and the latter Vitamin E was prepared starting from CN nanosuspension nanostructured powders. The coating deposited by a spray technique on three different renewable biodegradable films consisting of polyesters starch to prepare possible beauty mask prototypes. After drying, were extracted water contro...

Several shortcomings of the alloys that are used to fabricate a number of currentgeneration biomedical implants, such as Ti-6Al-4V alloy for the femoral stem of a total hip replacement and AZ3 Mg alloy for the scaffold of a fully bioabsorbable coronary artery stent, are well-known. Examples of these shortcomings are limited bioactivity/osseointegration (in the case of Ti-based alloys) and high ...

Bacteria are difficult to be eliminated because of their multi-drug resistance, which brings significant threats public health. Among the antibacterial methods, mechanobactericidal surfaces provide a possible approach solving this problem. In study, generally used mechanical sterilization is developed by fabricating nanostructured coating. The functional coating simply fabricated growing zeolit...

Electrically conductive nanofiber is well known as an excellent nanostructured material for its outstanding performances. In this work, poly(3,4-ethylenedioxythiophene) (PEDOT)-coated polyvinyl alcohol-graphene oxide (PVA-GO)-conducting nanofibers were fabricated via a combined method using electrospinning and electropolymerization techniques. During electrospinning, the concentration of PVA-GO...

Infection is the most common factor that leads to dental titanium implant failure. Antibacterial implant surfaces based on nano-scale modifications of the titanium appear as an attractive strategy for control of peri-implantitis. In the present work, the preparation and antibacterial properties of a novel composite coating for titanium based on nanoporous silica and silver nanoparticles are pre...

Highly adjustable and precisely controllable drug release from a biodegradable stent coating was achieved using a unique family of nanostructured hybrid polyurethanes. These polyurethanes are polyhedral oligosilsesquioxane thermoplastic polyurethanes (POSS TPUs) featuring alternating multiblock structures formed by nanostructured hard segments of POSS and biodegradable soft segments of a polyla...

Ice nucleation and accretion on structural surfaces are sources of major safety operational concerns in many industries including aviation renewable energy. Common methods for tackling these active ones such as heating, ultrasound, chemicals or passive surface coatings. In this study, we explored the ice adhesion properties slippery coated substrates by measuring shear forces required to remove...
