Increased proliferation of antimicrobial resistance and new strains bacterial pathogens severely impact current health, environmental, technological developments, demanding design novel, highly efficient antibacterial agents. Ag, Cu monometallic Ag/Cu bimetallic nanoparticles (NPs) were in situ grown on the surface graphene, which was produced by chemical vapor deposition using ferrocene as precursor further functionalized to introduce oxygen-containing groups. The performance resulting...
Self-healing concrete has the potential to optimise traditional design approaches; however, commercial uptake requires ability harmonize against standardized frameworks. Within EU SARCOS COST Action, different interlaboratory tests were executed on self-healing techniques. This paper reports evaluation of effectiveness proposed experimental methodologies suited for with expansive mineral additions. Concrete prisms and discs MgO-based healing agents produced precracked. Water absorption water...
Titanium dioxide (TiO2) is an excellent photocatalytic material that imparts biocidal, self-cleaning and smog-abating functionalities when added to cement-based materials. The presence of TiO2 influences the hydration process cement development its internal structure. In this article, a pore network pastes containing different ratios were studied using two noninvasive techniques (ultrasonic NMR). Ultrasonic results show addition enhances mechanical properties paste during early-age...
Abstract Halide organic–inorganic perovskites (HOIPs) are a promising class of materials for neuromorphic computing and processing systems demonstrating variety resistive switching (RS) mechanisms. HOIPs have been used as active layers in two‐ three‐terminal synaptic devices reporting high performance metrics speed energy consumption. Nevertheless, halide suffer from poor ambient stability reproducibility. In this work, highly robust double memristor based on two forming stacking...
In the present study, graphene oxide (GO), reduced (rGO) and carboxylated (GCOOH) have been incorporated in lime-pozzolan-cement pastes, aiming to develop self-sensing binders that would be used for restoration applications. Τhe mechanical electrical properties of newly-developed nanocomposite pastes were examined compared against respective a reference paste. The incorporation different types nanostructures significantly increased compressive strength all investigated while highest increase...
Self-healing cement composites are considered to be an effective solution towards the enhancement of sustainability and service-life concrete structures, as well reduction repair maintenance cost. Among several self-healing technologies, encapsulated healing agents present benefits that include larger cracks timeless potential upon damage. This paper presents a critical overview progress made in development agents, along with main achievements related their integration mixtures. Encapsulated...
