In this work, colloidal gold nanoparticles (AuNPs) stabilized into a chitosan matrix were prepared using green route. The synthesis was carried out by reducing Au(III) to Au(0) in an aqueous solution of and different organic acids (i.e., acetic, malonic, or oxalic acid). We have demonstrated that varying the nature acid it is possible tune reduction rate precursor (HAuCl(4)) modify morphology resulting metal nanoparticles. use chitosan, biocompatible biodegradable polymer with large number...
A stable and improved control of the wettability textiles was obtained by using a coating diamond like carbon (DLC) films on cotton PECVD. By controlling different plasma pretreatments argon, oxygen, hydrogen fibers' surface, we have shown that had significant impact behavior resulting from an induced nanoscale roughness combined with incorporation selected functional groups. Upon subsequent deposition films, fibers yield to highly controlled chemical stability hydrophobic state could be...
Chitosan films containing mesoporous SBA-15 supported silver nanoparticles (AgNPs) were prepared to be applied as a potential wound dressing material. First SBA-15–silver nanoparticle (SBA-15–Ag) composite materials by controlled annealing process without the use of organic solvents and reagents. The SBA-15–AgNPs characterized in detail X-ray powder diffraction, field emission scanning electron microscopy transmission which evidenced presence uniformly distributed nanostructures inside...
Magnetic silk fibroin protein (SFP) scaffolds integrating magnetic materials and featuring gradients were prepared for potential utility in magnetic-field assisted tissue engineering. nanoparticles (MNPs) introduced into SFP via dip-coating methods, resulting with different strengths of magnetization. showed excellent hyperthermia properties achieving temperature increases up to 8 °C about 100 s. The not toxic osteogenic cells improved cell adhesion proliferation. These findings suggest that...
Fire gilding and silvering are age-old mercury-based processes used to coat thesurface of less precious substrates with thin layers gold or silver. In ancient times, these methods were produce decorate different types artefacts, such as jewels, statues, amulets, commonly-used objects. Gilders performed not only objects but also simulate the appearance silver, sometimes fraudulently. From a technological point view, aim workmen over 2000 years ago was make metal coatings adherent possible....
Silk fibroin (SF), a protein core fibre from the silkworm Bombyx mori, has huge potential to become sustainable, biocompatible, and biodegradable material platform that can pave way towards replacement of plastic in fabrication bio-derived materials for variety technological biomedical applications. SF remarkable mechanical flexibility, controllable biodegradability, biocompatibility is capable drug/doping inclusion, stabilization release. However, dielectric properties limit its as direct...
Ground Penetrating Radar (GPR) is a flexible and cost-effective tool for performing structural integrity assessment quick damage evaluation of manmade structures, including cultural heritage (CH) assets. In this context, paper deals with the usefulness GPR surveys enhanced by use Microwave Tomographic data processing approach as methodology diagnosis monitoring CH exposed to climate events natural hazards. Specifically, reports on results measurement campaign carried out at Loggia Consoli...
Properly functionalized amphiphilic cyclodextrins (CDs) can act as capping agents for gold colloids in solution (Mazzaglia, A.; et al. J. Phys. Chem. C 2008, 112, 6764). In the present work, we report a study on hybrid nanoparticles/amphiphilic CD supramolecular system assembled onto surface by both field emission scanning electron microscopy (FE-SEM) and X-ray photoelectron spectroscopy (XPS) techniques. Amphiphilic CDs bearing respectively thioalkyl chains with different length primary...
Cultural Heritage (CH) (In the context of this paper, we consider cultural heritage built tangible heritage, such as buildings or monuments.) is an important source identity for humankind and needs to be conserved future generations. Climate change (CC) will morph environmental landscape, thus leading climate stress imposed on CH. Experts from different domains, including, but not limited to, material scientists, conservators managers collaborate find out how CC affects CH potentially...
