Commercial and home prepared TiO<sub>2</sub> samples were functionalized with a commercial Keggin heteropolyacid (HPA) H<sub>3</sub>PW<sub>12</sub>O<sub>40</sub> (PW<sub>12</sub>) or hydrothermally K<sub>7</sub>PW<sub>11</sub>O<sub>39</sub> salt (PW<sub>11</sub>).
Coating of flexible substrates is crucial to prepare versatile, multifunctional materials. However, exploration effective fabrication approaches still a challenging issue, because the pathways generally proposed require time-consuming, multistep protocols. Here, we developed one-pot process for decorating either pearl necklace-like or fibrous fluffy-like structures polycaprolactone (PCL) with graphene oxide (GO) skin. PCL solutions were dry jet-wet electrosprayed electrospun into stirred...
Background/Objectives: Following tooth extraction, resveratrol (RSV) can support healing by reducing inflammation and microbial risks, though its poor solubility limits effectiveness. This study aims to develop a solid nanocomposite embedding RSV in lipid nanoparticles (mLNP) within hydrophilic matrix, the scope of improving local delivery enhancing healing. Hydroxyapatite (HXA), often used as bone substitute, was added prevent post-extraction alveolus volume reduction. Methods: The mLNP-RSV...
The catalytic dehydration of fructose to 5-hydroxymethylfurfural (HMF) in water was performed the presence pristine Nb2O5 and composites containing Nb Ti, Ce or Zr oxides. In all experiments, converted HMF using as solvent. catalysts were characterized by powder X-ray diffraction, scanning electron microscopy, N2 physical adsorption, infrared Raman spectroscopy temperature-programmed desorption NH3. Experimental parameters such initial concentration, volume reacting suspension, operation...
Next-generation alkaline water electrolyzers will be based on zero-gap configuration to further reduce costs related technology and improve performance. Here, anodic porous transport layers (PTLs) for electrolysis are prepared through a facile one-step electrodeposition of Ni,Fe,Co-based layered double hydroxides (LDH) 304 stainless steel (SS) meshes. Electrodeposited LDH structures characterized using Scanning Electron Microscopy (SEM) confirming the formation high surface area catalytic...
Nowadays, there is a growing need to reduce the environmental impact generated by use of inorganic materials for building applications. The aim this work investigate bio-lime based mortar flexural toughness improvement due addition common reed fibers (Arundo donax L.) in order evaluate their possible application as ductile eco-compatible prefabricated bricks or laying and joint mortars masonry. Different sets specimens were tested varying fiber weight content length. Moreover, chemical...
Aromatic plants represent a source of natural products with medicinal properties, and are also utilized in the food pharmaceutical industries. Recently, need for eco-compatible non-toxic products, safe both environment human health, have been proposed sustainable conservation historic–artistic artifacts. In this study, order to counteract microbial colonization (Aspergillus sp., Streptomyces Micrococcus sp.) on wooden artwork surfaces, Thymus vulgaris L. (Lamiaceae) essential oil (EO)...
Eco-friendly and cheap treatments based on the use of mildly alkaline solutions have been recently investigated to modify natural fibers, altering their surface improving compatibility mainly with polymer matrices. A challenge for researchers is nowadays represented by assessment this kind as a viable approach also geopolymer composites. In such context, study presents novel sustainable enhancing sisal fibers composites using sodium bicarbonate (NaHCO3) treatment. While treatment offers...
The weathering degree of the building materials and natural stones is generally quantified as decrement some mechanical features that can be measured experimentally by means compressive tests or point load in laboratory Schmidt hammer carried out situ. Such destructive damaging are unacceptable case cultural heritage since even small amounts damage must avoided. This work shows a correlation between rebound values reflectivity detected terrestrial scanner laser; therefore it allows assessing...
Thermal oxidation of titanium was carried out at 350°C, 450°C, and 550°C for 2 h or 12 h. X-ray Diffraction Raman Spectroscopy suggest that the thermal oxides are scarcely crystalline when annealing temperature is low, while both anatase rutile present high time. Photoelectrochemical measurements allowed estimation a bandgap decreasing from 3.35 eV to 3.15 with increasing temperature. The impedance spectra confirmed formation n-type semiconductors, an strongly on going reverse bias toward...
Abstract The treatment of stone surfaces for their protection from ageing caused by natural and anthropogenic effects is an open issue in materials development Cultural Heritage. We thought interesting to verify the suitability a modified cellulose biofilm filled with halloysite nanotubes as wax compatibilizers design protecting layer. A hydraulic mortar was selected prototype. To improve physico-chemical properties covering layer, microparticles have been incorporated control transport,...
