The modernization, efficiency, and decarbonization of the energy supply systems are among new challenges to be faced in coming decades achieve targets objectives dictated by European strategic policies. Despite countless benefits related renewable sources (RES) integration, this brings key power system, such as risk imbalance between generation demand, sudden changes flows transmission lines with a need for expensive time-consuming upgrades, withdrawal conventional consequent demands...
A vegetable tannin, a flavonoid-type natural polyphenolic compound, was used to promote the stabilization of polyurethane foams against UV radiation. Several were synthesized by using an isocyanate, and mixture ethoxylated cocoalkyl amine tannin. The content tannin varied from 0 40 wt %. effects water (used as blowing agent) on foaming kinetics cellular morphology investigated. Samples subjected accelerated weathering under radiation for 3 24 h, FTIR DMA analyses conducted assess performance...
Organic–inorganic hybrid foams were prepared by using metakaolin or diatomite as a partial (or total) replacement of metakaolin, precursor and metal silicon whipped protein blowing agents. The foamed systems cured at defined temperature time then characterized chemical point view through Fourier transformed infrared spectroscopy X-ray diffraction mechanical morphological compression tests scanning electron microscopy. experimental findings highlighted that the in formulation affected...
Poly(Ethylene 2,6‐Naphthalate)—PEN has been used as matrix for laminates with the aim to develop woven fiber reinforced composites a service temperature high 100°C. Three different classes of fibers have considered reinforcement in fabric form: carbon, polymers (Twaron and Vectran) mineral (basalt). Composites were manufactured by using film stacking technique, alternating layers balanced plain weave fabrics (0/90) films amorphous PEN. The manufacturing process was optimized obtain good...
About one-third of world energy production is destined to the industrial sector, with process heat accounting for about 70% this demand; almost half quota required by endothermic processes operating at temperatures above 400 °C. Concentrated solar thermal technology, thanks cost-effective high-temperature storage solutions, can respond renewable needs thus supporting decarbonization hard-to-abate processes. Particularly, parabolic trough technology using binary molten salts as transfer fluid...

High performance fiber reinforced polymer composites are made by embedding high strength/modulus fibers in a polymeric matrix. They class of materials that owe its success to the impressive specific mechanical properties with respect metals. In many weight-sensitive applications, where and low mass required, per unit more important than absolute further weight reduction is desirable. A route reach this goal could be controlled induction porosity into matrix, while still ensuring load...
Composite lightweight materials based on a polymeric matrix with embedded magnetic micro-particles have been developed. The application of field (MF) during the foaming samples induced alignment particles along MF lines, forming reinforcing chain-like structures. presence aligned imparted an anisotropic mechanical behavior particle direction, thus strongly improving stiffness and strength compared to randomly filled systems. pre-strained magneto-mechanical characterization resulted in direct...
Natural porous materials, like wood or bone, are multiscale cellular composite structures which exhibit mechanical (such as elasticity and strength) functional the thermal acoustic insulating properties) behaviors dependent on measuring direction. They show best performance/weight ratio among all materials because their response is optimized in needed direction by removing matter where not strictly functional, giving a result strong structural well morphological anisotropy.
