The failure analysis of a fire-damaged liquid oxygen gate valve is presented. During start-up operations of a liquid oxygen system, a gate isolation valve experienced an internal ignition that propagated in the valve and breached the extended bonnet under pressure. The resulting fire led to the fatality of two operato…
The paper discusses the electrochemical interactions of Co-Cr alloy with different physiological solutions and organic substances, containing different ions and different pH values, which should play a key role in the materials lifetime. The physical and chemical reactions are numerous and the passivity of the Co-Cr a…
In this paper, we proposed a phase-change memory (PCM) structure which has a ring confined chalcogenide (RCC) for reducing reset operation current. The temperature distributions of normal bottom contact (NBC), confined chalcogenide (CC) and proposed RCC PCMs were simulated by 3 dimensional finite element method. It wa…
Two kinds of powders of 3 mol. % yttria stabilized zirconia (3Y–TZP) with different particles sizes; one was 20 nm denoted by N whereas the other was 0.5 µm denoted by M, were mechanically mixed via ball milling machine using different amounts of N wt. % to obtain multiscale zirconia composite powder. Then the mixed p…
The influence of 1 wt.% and 2 wt.% of graphene platelets (GPLs) addition on indentation fracture toughness (IF) of aluminium oxide (Al2O3) and silicon nitride (Si3N4) based composites has been investigated and compared to the monoliths. Ceramic composites reinforced with GPLs were prepared using hot-press processing t…
Two-dimensional (2D) materials are crystalline solids consisting of a single layer or a few layers of atoms. Since the isolation of graphene in 2004, a tremendous amount of research has shown that 2D materials have numerous applications in electronics, photonics, and optoelectronics at the nanoscale. This feature issu…
Polycrystalline perovskite-type manganite La0.65Sr0.2Na0.15MnO3 was prepared by sol-gel method. An X-ray diffraction measurement showed that the sample was a single phase. The Curie temperature of the sample was determined to be 350K. The maximum magnetic entropy change |ΔSM| corresponding to a 1T magnetic field varia…
This research presents microstructural characterization of the CoNi Al shape memory alloy with focus on understanding the significant properties as well as the relation between the physical properties and microstructure of this alloy. Melting technique were used to prepare Co Al Ni shape memory alloys, where scanning…

The multiferroic BiFeO3 powders with perovskite structure were synthesized by sol-gel auto-combustion and conventional sol-gel methods, respectively. As-prepared powders were characterized by XRD, SEM and VSM techniques to investigate phase structure, microstructure and magnetic properties. The results show that the p…

Summary The broadly apposite bioplastic, poly lactic acid was synthesized by using deinked paper waste as substrate, fermentation with Saccharomyces cerevisiae under controlled laboratory conditions followed by condensation polymerization. The substrate was initially subjected to acid hydrolysis followed by alkali neu…
Evaluation of cavitation erosion resistance of is carried out by using various testing stands, that differ by the way of cavitation excitation and its intensity. These various testing conditions have led to a standardization of some part of laboratory stands, that in turn allows a direct comparison of results obtained…
Magnesia-spinel composites were prepared by sintering at 1800°C in N2 with fused magnesia, sintered magnesia, MgO-Al2O3 spinel as raw materials and Al powder as additive. The compositions and microstructure of sintered products were investigated by XRD and SEM. The results show that a little AlN and MgAlON has been de…

A series of porphyrins with directly meso-attached “sucrose” moiety by the carbon C-6′ of its “fructose” end was synthesized, and their physico-chemical and aggregation properties studied by spectroscopic (fluorescence, circular dichroism, resonance light scattering) techniques. The effect of selected porphyrins on tu…
