Textile-based capacitors have been made from polyethylene dioxythiophene, polystyrene sulphonate (PEDOT:PSS) as the electrolyte and pure stainless steel filament yarns as the electrodes. The capacitor is well integrated into the textile structure, small in size and of light weight. Although they experience a self-disc…
Adjustable speed drives for rotating machines have become increasingly popular as they provide possibilities of smooth and accurate process control as well as for energy savings. In such systems, due to the fact that the voltage applied at terminals of motor windings is no longer purely sinusoidal but characterized by…
The aim of the research was to investigate the influence of silver coated yarns incorporated into fabric on the electrical and shielding properties of textile materials designed to en-sure protection against the risk of harmful electromagnetic fields as well as thermophysio-logical comfort in a warm climate. The weari…
Electromagnetic forming (EMF) has been proved to be a useful method to form the aluminium alloy sheet as it has so many advantages. As a high-speed forming process, it can suppress crack, reduce springback, and improve the formability of material at room temperature. But in the process of EMF, the rebound effect cause…

This work investigates an emerging and promising soil stabilisation method known as bio-cementation using microbial-induced calcite precipitation (MICP). MICP utilises bacteria to hydrolyse urea to give carbonate ions which react with a calcium-rich solution (i.e. calcium chloride) to produce calcium carbonate (calcit…
Tensile response at low strains and damping capacity were characterized in pure magnesium and Mg-1 mass%Ca alloy with the aim of revealing the effect of extrusion process and Ca addition. The damping capacity of extruded magnesium and solution treated Mg-1 mass%Ca alloy was lower than that of cast magnesium in the str…
The development of sustainable construction and building materials with reduced environmental footprint, in both manufacturing and operational phases of material life cycle, is attracting increasing interest. In this frame, new geopolymer-based materials seem very attractive, due to their good mechanical properties, c…
This thesis is a research-focused work on a study of alternative materials for horseshoes. Within this thesis the objectives and functions of a compliant horseshoe are identified, based on a litera ...
Long portions of the Apulian coast are steep cliffs in carbonate soft rocks. These, especially the calcarenite, are affected by weathering processes that markedly alter their mechanical properties with time, potentially leading to instability of coastal geomorphological structures. Such alterations are mainly due to c…
Alloy ATI 718Plus relies upon the co-precipitation of secondary phases n and 5 at the grain boundaries to control grain structure during processing. Abundant precipitation can occur in the billet material during heating time before sub-solvus forging, which persists to a certain extent in the microstructure of the fin…
Hot workability of Zr alloy has been investigated by means of hot compression test using Gleeble-3800. Hot compression test was performed in the temperature and strain rate range of 700 to 925oC and 0.01 -10s-1, respectively. Deformation behavior was characterized with the help of processing maps using Dynamic Materia…
Three-dimensional integrated circuits (3D ICs) with advanced cooling systems are emerging as a viable solution for many-core platforms. These architectures generate a high and rapidly changing thermal flux. Their design requires accurate transient thermal models. Several models have been proposed, either with limited…
AD730tm was designed to be a cost effective superalloy for high temperature turbine disks. This superalloy, strengthened by gamma prime precipitates, presents a good ability for cast and wrought process route and a high combination between high temperature mechanical properties and cost. A study was performed to optim…
A polar poly(vinyl alcohol) foam was studied as a function of water content by thermal processing method in present study.The effect of moisture on the melting behaviour of poly(vinyl alcohol) as well as the mechanism of cell nucleation and bubble growth were investigated.The results showed that the water in modified…
High purity isopropyl alcohol cannot be obtained from an aqueous solution by conventional distillation because isopropyl alcohol in solution will reach an azeotropic point around 68 mole % (88 wt.%).However, high purity isopropyl alcohol can be obtained by using ethylene glycol or dimethyl sulfoxide as a solvent in th…
The kinetics of the preparation of biopolymers from two triglyceride oils- melon seed and cottonseed oils were studied using alcoholysis-polycondensation process. Six grades of biopolymers formulated to have oil content of 40% (A), 50% (B), and 60% (C) melon seed oil (MESO) and 40% (D), 50% (E), and 60% (F) cottonseed…
The biochemical impacts of five chemical compounds i.e., pesticide formulation ( methomyl, lambada-cyhalothrin, thiamethoxame), biobesticide (spinosad) and Tannic acid (as a natural product, polyphenols) were studied against two land snail species, Eobania vermiculata and Monacha obstructa using the bait technique. Th…
There has been extensive research and development activities in the field of nanofibrillated cellulose (NFC) materials during recent years, although microfibrillated cellulose was developed already ...
To realize the removal of Cu from iron scraps by a segregation during solidification, we demonstrated the Cu segregation in Fe-C-Cu alloy by unidirectional solidification of utilizing a temperature gradient. The effect of cooling rate and initial Cu content of Fe-C-Cu alloy on the segregation behavior of Cu was invest…
