Performance of Polymer Modified Polypropylene Fiber Reinforced Concrete
Abstract: AbstractThe fiber reinforced concrete (FRC) is a composite material essentially consisting of conventional concrete reinforced by random dispersal of short, discontinuous and discrete fibers of specific geometry. The conventional plain concrete possesses high compressive strength, low tensile strength, poor impact strength, ductility, and little resistance to cracking and poor resistance to chemical attack. The presences of micro-cracks at the mortar aggregate interface are responsible for the inherent weakness of plain …

Unraveling Mixed Ionic-Electronic Conduction in Lithium-Substituted Rubidium Tetra Titanates via Dielectric Spectroscopy and EPR Analysis
Abstract: Lithium-substituted Rubidium Tetra Titanates with varying concentrations of lithium carbonate (Li₂CO₃) — specifically 0.01, 0.05, and 0.1 molar percentages — were successfully synthesized using a conventional high-temperature solid-state reaction method. The resulting compounds follow the general chemical formula Rb₂₋ₓLiₓTi₄O₉. X-ray diffraction (XRD) analysis confirmed that lithium ions were successfully incorporated into the crystal lattice without disrupting the fundamental layered structure of the host material. The crystal system remained monoclinic across …
