The effect of thermal annealing on the bolometric properties of TiO2−x films was investigated. The test-patterned TiO2−x samples were annealed at 300 °C temperature in order to enhance their structural and electrical properties for effective infrared image sensor device applications. The crystallinity was changed from…
Electrospun polymer nanofibrous mats loaded with ionic liquids (ILs) are promising nonvolatile electrolytes with high ionic conductivity. The large cations of ILs are, however, difficult to diffuse into solid electrodes, making them unappealing for application in some electrochemical devices. To address this issue, a…

Nanostructured Mg2Ni intermetallic compounds were synthesized by high-energy ball milling. Effect of milling time on structure and surface morphology of milled powders were studied using x-ray diffraction and scanning electron microscopy. Crystallite size and degree of crystallinity were confirmed by using transmissio…
An algebraic expression for the Preisach hysteron, which is a nonideal (delayed) relay operator, is formulated for a computationally efficient real-time implementation. This allows representing the classical scalar Preisach hysteresis (SPH) model as a summation of a large number of weighted hysterons, in which computa…
The comprehensive mechanism of updatable holographic diffraction is presented for a monolithic compound of 3-[(4-nitrophenyl)azo]-9H-carbazole-9-ethanol (NACzE) dispersed poly(methyl methacrylate) film device. The maximum sensitivity occurs at 561 nm, which well coincides with an isosbestic point between cis - trans i…
Bonding individual metallic nanoparticles at small separation distances to let them form dimers and making them available in large quantities is a key requirement for various applications that wish to exploit the tremendous enhancement of electromagnetic fields in plasmonic junctions. Although progress has been witnes…
The present study shows the electrodeposition of MnO2 from KMnO2 solution and its electrochemical studies. XRD analysis shows the electrodeposited MnO2 has nano-sized particle of 18 nm. The electrochemical properties have been investigated using the cyclic voltammetry, galvanostatic charge/discharge and impedance tech…
The broadband directive in-phase emission from an array of sources conformed cylindrically is numerically and experimentally reported. Such manipulation is achieved through the use of a lens designed by transformation optics concept. The all-dielectric lens prototype is realized through three-dimensional (3D) polyjet…
The concept of a "microbicide" was born out of the lack of a vaccine against HIV and the difficulty of women in ensuring the use of preventive prophylaxis by their partners, especially in developing countries. Approaches using polyanionic carbosilane dendrimers have shown promise in the development of new microbicides…
The composition-dependent crystal structure, elastic modulus, phase stability, and magnetic property of ${\mathrm{Ni}}_{2\ensuremath{-}x}{\mathrm{Co}}_{x}{\mathrm{Mn}}_{1.60}{\mathrm{Sn}}_{0.40}\phantom{\rule{4.pt}{0ex}}(0\ensuremath{\le}x\ensuremath{\le}0.50)$ are studied by using first-principles calculations in com…
Hydrophilic polymers are the most common group of polymers used in the preparation of modifiedrelease drug delivery systems. This is due to their versatility, low cost, high production yield, as well as easy manufacturing and adequate in vitro/in vivo correlation. In normal physiological conditions, the matrix control…
Carbon nanoparticles (C-dot) are materials that belong to a class of 0-dimensional nanoparticles with a photoluminescence property. C-dot can be synthesized from a variety of organic acids through bottom-up synthetic methods or from other source of inorganic carbons through top-down synthetic methods. Herein, we repor…
Tuning the porosity of zinc oxide electrodes: from dense to nanopillar films, Fanni, Lorenzo, Delaup, Benoît, Niesen, Bjoern, Milstein, Yonat, Shachal, Dubi, Morales-Masis, Monica, Nicolay, Sylvain, Ballif, Christophe
In the present study, we use molecular dynamics (MD) simulations to provide an insight into the system size effect on the self-diffusion coefficient of liquids in the periodic rectangular parallelepiped system, from the hydrodynamic perspective. We have previously shown that in the rectangular box system, the diffusiv…
Poly(butylene terephthalate)-poly(tetramethylene glycol) (PBT-PTMG) copolymer is prepared with terephthalic acid (PTA) rather than its dimethyl ester (DMT) as starting material by a two-step melt polycondensation. This process includes the synthesis of PBT prepolymer from PTA with 1,4-butanediol (BDO) in the first ste…
Magnetite (Fe3O4) is the most commonly and extensively explored magnetic nanoparticles (MNPs) for drug-targeting and imaging in the field of biomedicine. Nevertheless, its potential application as safe and effective drug-carrier for CNS (Central Nervous System) anomalies is very limited. Previous studies have shown an…
Coulomb's law is one of the most fundamental laws of physics that describes the electrostatic interaction between two like or unlike point charges. Here, we experimentally observe a strong effect of Coulomb interaction in tightly coupled terahertz metamaterials where the split-ring resonator dimers in a unit cell are…
Magnetic as well as calorimetric measurements have been performed on single crystal samples of $\mathrm{P}{\mathrm{r}}_{0.6}\mathrm{S}{\mathrm{r}}_{0.4}\mathrm{Mn}{\mathrm{O}}_{3}$ and $\mathrm{N}{\mathrm{d}}_{0.6}\mathrm{S}{\mathrm{r}}_{0.4}\mathrm{Mn}{\mathrm{O}}_{3}$ to develop a complete critical behavior study of…
Insulin-containing microcapsules were prepared by a layer-by-layer (LbL) deposition of poly(allylamine hydrochloride) (PAH) and polyanions, such as poly(styrenesulfonate) (PSS), poly(vinyl sulfate) (PVS), and dextran sulfate (DS) on insulin-containing calcium carbonate (CaCO3) microparticles. The CaCO3 core was dissol…
