An optically readable write once read many memory (WORM) in Ag/Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH PPV)/ITO is demonstrated in this work. Utilising characteristics of the organic light emitting diode structure of Ag/MEH PPV/ITO and electrochemical metallization of Ag, a WORM with light emitt…
In this paper we review the results of the research and development of photonic structure devices performed in the Institute of Materials Science in the period from 2010–2015. We have developed a configuration of 1D photonic crystal (PC) microcavities based on porous silicon (PS) layers and applied them to optical sen…
A comparative study of scratch behavior of single‐ and bi‐layer hard coatings deposited on poly(methyl methacrylate) substrates was investigated. Trimethylolpropane triacrylate (TMPTA) and pentaerythriol triacrylate (PETA) with different chemical structure were chosen as a top layer for bilayer coatings, and soft base…
In this paper, we report a facile method to prepare a twins-structural Sn@C core–shell composite that is used as anode materials for lithium-ion batteries. Its surface morphology and microstructures were characterized by the scanning electron microscope, X-ray diffraction, and transmission electron microscope. The ele…
A pioneer in-situ synchrotron X-ray nanodiffraction approach for characterization and visualization of strain fields induced by nanoindentation in amorphous materials is introduced. In-situ nanoindentation experiments were performed in transmission mode using a monochromatic and highly focused sub-micron X-ray beam on…
Porous metal structures have many benefits over fully dense structures for use in bio-implants. The designs of porous structures can be made more sophisticated by altering their pore volume and strut orientation. Porous structures made from biocompatible materials such as titanium and its alloys can be produced using…
Clay/mercaptosuccinic acid hybrids were prepared through radical thiol‐ene coupling between methacrylate‐silanized clay and mercaptosuccinic acid. The clay surface was modified by 3‐trimethoxysilylpropylmethacrylate, then mercaptosuccinic acid was clicked by ultraviolet (UV)‐triggered thiol‐ene addition reaction at 36…
The advanced strategy of processing of NMR cross-polarization (CP) data has been developed separating the short-range order- and the bulk effects in the manifold of spin interactions. The effectiveness of such treatment have been demonstrated on 1 H– 31 P CP kinetics in the nanostructured calcium hydroxyapatite (nano-…
Malaria is a global disease that desires early diagnosis in the field, for which one way is to detect hemozoin (a unique biomarker of malaria infection) at low concentrations. Moreover, many anti-malarial drugs inhibit the formation of hemozoin and facilitate toxic free heme stacking to kill malaria parasites. Therefo…
Radio-frequency (RF)-enhanced surface erosion of beryllium (Be) plasma-facing components is explored, for the first time, using the ERO code. The code is applied to measured, RF-enhanced edge Be line emission at JET Be outboard limiters, in the presence of high-power, ion cyclotron-resonance heating (ICRH) in L-mode d…
Soap is the most useful things which we use our everyday life in various cleansing and cosmetics purposes. Jatropha oil is nonedible oil which has more benefits to soap making. It has also cosmetics and medicinal properties. But the presence of toxic Phorbol esters in Jatropha oil is the main constrains to use it. So…
Abstract A cost‐effective, operationally simple and eco‐compatible protocol for the one‐pot synthesis of photochromic pyrans by the reaction of propargyl alcohols as well as propargyl ethers with differently substituted phenols under ambient atmosphere in aqueous medium has been developed using β‐cyclodextrin hydrate…
In this study, BaZrO3:Eu0.025 powder was synthesized through the solid-state reaction method with two different heating processes. For the one-step process, the BaZrO3:Eu0.025 powder was heated to 1000 °C–1400 °C for 2 h. For the two-step heating process, the BaZrO3:Eu0.025 powder was pre-heated at 800 °C for 2 h, aft…
There is much current interest in combining superconductivity and spin–orbit coupling in order to induce the topological superconductor phase and associated Majorana-like quasiparticles which hold great promise towards fault-tolerant quantum computing. Experimentally these effects have been combined by the proximity-c…
We studied the superconducting proximity effect under photoexcitation by illuminating a superconductor/monolayer graphene/superconductor (SGS) Josephson junction with monochromatic light at a wavelength of 1.31 μm. Although the critical current Ic can be controlled by the irradiation power P, its variation cannot be e…
Purpose – This paper aims to present certain issues in direct bonded copper (DBC) technology towards the manufacture of Al2O3 or AlN ceramic substrates with one or both sides clad with a copper (Cu) layer. Design/methodology/approach – As part of the experimental work, attempts were made to produce patterns printed on…
Abstract The influences of microstructures and orientations on fracture toughness of intermetallic phase Al2Cu‐based alloys during different directionally solidified rates were investigated. With solidified rates increasing, the patterns of Al2Cu phase dendrite turned from faceted V‐shaped morphology to elongated plat…
For improved physical stability and fast accumulation in sentinel lymph nodes in vivo, indocyanine green (ICG) was incorporated into exosomes (EXOs) to form a novel ICG-based near-infrared fluorescence probe. Compared with free ICG, prepared ICG-TBAI-encapsulated EXOs (ICG/EXOs) smaller than 50 nm had greater physicoc…
Abstract A plastic‐bonded explosive (PBX) in the form of a sheet was formulated comprising of 1,3,5‐trinitroperhydro‐1,3,5‐triazine (RDX) and an hybrid binder system containing a linear thermoplastic polyurethane and a fluoroelastomer (Viton). The effect of a fluoroelastomer on the explosive as well as mechanical prop…
Dopant-profile independent electron transport has been observed through a combined study of temperature dependent electrical resistivity and magnetoresistance measurements on a series of Ti incorporated ZnO thin films with varying degree of static-disorder. These films were grown by atomic layer deposition through in-…
