Carbon reinforced concrete is an artificially produced composite construction material consisting of two components: concrete and continuous carbon filaments formed as roving fabric or bars. The research project C³-V1.5 “Demolition, Dismantling and Recycling” aims to answer the key questions regarding the LCA. Under t…
Abstract Carbonised palm kernel shell was employed to improve water purification property of clay-sand mixture used as water filter in the rural areas. Quantity of carbonised palm kernel shell in clay-sand mixture was varied. Different proportions of carbonised palm kernel shell were mixed with certain proportion of c…
This work is devoted to study punching shear strength of reactive powder concrete slab reinforced with CFRP bars. The experimental program includes investigating the effect thickness of slab on the first crack, type of failure, load – deflection curve and compression the ultimate punching shear capacity with ACI – 440…
Transition metal dichalcogenides (TMDs) have attracted vast interest as layered semiconductors with high electrical and optical properties. Among them, monolayer MoS2 is a direct gap semiconductor with its gap energy in the visible range (Fig. 1(a)). Interestingly, excitonic states in monolayer MoS2 are stabilized owi…
Underwater explosions (UNDEX) generated by torpedos and mines present one of the most significant threats to the survivability of naval vessels. A non-contact UNDEX event produces two distinct pressure loading phenomena: an initial short duration, high frequency shock wave followed by a relatively low frequency pulsat…
The Hybrid Multi Bend Achromat: from SuperB to EBS. The motivations and rationale at the basis of the Hybrid Multi Bend Achromat (HMBA) lattice and its evolution through the years are presented. Its implementation in the ESRF Extremely Brilliant Source (EBS) upgrade is also shown.
The main aim of this thesis work is to investigate the electrical, optical and thermal impact characteristics of cobalt oxide doped antimony tin oxide (CoO-ATO) in the form of thin films and nanofiber membranes. CoO-ATO is a novel composite material that has the potential to be used as reinforced aircraft coatings, mi…
The development of new multifunctional coatings with antimicrobial properties has a special interest in several applications for pharmaceutical and medical products. This work reports on the deposition of antimicrobial coatings based on silver nanoparticles (Ag NPs) embedded in an organosilicon film onto woven and non…

A comprehensive survey of the available literature showed that in the last few decades, there has been a growing interest in the use of thermoplastic vulcanizates (TPVs). TPVs are the second largest group of soft thermoplastic elastomers (TPEs) after styrene-based block copolymers, and offer a wide range of potential…
The ESS Target Proton Beam Imaging System will image the 5 MW ESS proton beam as it enters the spallation target. The system will operate in a harsh radiation environment, leading to a number of challenges: development of radiation hard photon sources, long aperture-restricted optical paths, and fast electronics to pr…
Carbon nanomaterials such as carbon nanotubes (CNTs) or monolayer graphene are proposed for a wide variety of theoretical applications due to the superior properties provided at the nanoscale. They can be produced by chemical vapor deposition (CVD), which consists on the thermal decomposition of hydrocarbons over meta…

Eric A. Stinaff 2D semiconductors like MoS2 exhibit unique optical properties.Light-matter interactions in such materials results in enhanced excitonic effects.In this thesis, we study the effect of electric field on an electron-hole system by observing the changes in the photoluminescence.We have tried to explain the…
Pthallic acid -melamine -formaldehyde copolymer resin was synthesized through the condensation of pthallic acid and melamine with formaldehyde in the presence of hydrochloric acid as a catalyst and with various molar ratios of the reacting monomers. The resulting copolymer was characterized with UV-visible, FTIR, 1 H-…
Thermoelectric generator (TEG) materials provide a unique solid-state energy conversion from heat to electricity. Nanostructured TEGs experiencing transient thermal loads at medium to high-temperatures are susceptible to degradation due to thermal stress cracking, which subsequently causes decreased lifetime. Previous…
The article is dedicated to the construction of the "bending moment – curvature" diagrams for rectangular cross-sections of reinforced concrete bending elements. Assumptions and equilibrium equations used in the construction of diagrams are given in the article. The algorithm for the construction of the "bending momen…
The applicability of the modified Gurson - Tvergaard - Niedelman (GTNm) model to computations is considered; in the frame of numerical modeling, the model makes it possible to obtain failure surfaces, realized in experiments with samples, which include scroll-type surfaces. Tests on static tension of plates (prismatic…
The results are presented of experimentally investigating tension of gas-impermeable packages of woven metal grids formed by freely stacking up grid layers, maintaining the orientation of the wires. The results of experimentally studying tension of grid packages in the direction of wires show that their pre-cogging no…
The effect of an EA-grade low-viscosity thinner and of temperature on the rheokinetic properties of an epoxy oligomer of grade UP-610 cured with a Benzam-ABA amine curing agent was investigated. It was established that, when thinner is introduced and the temperature is varied, the lifetime of EFA-B epoxy binder can va…
