Epitaxial Pb(Zr,Ti)O3 (PZT) films were deposited on Nb-doped SrTiO3 (Nb:STO) monocrystalline wafers by a sol-gel method. It was observed that phase structure of prepared films depends on the orientation of Nb:STO substrates. Interestingly, tetragonal structure was only found for [001]-oriented PZT film on Nb:STO(100)…
Multifunctional BiFeO3 (BFO), BiCrO3 (BCO), and BFO/BCO heteroepitaxial films with good ferroelectric properties were grown by pulsed laser deposition on epitaxial CaRuO3-coated (100)-oriented LaAlO3 and (LaAlO3)0.3(Sr2LaTaO6)0.7. The in-plane compressive strain induces a tetragonal crystal structure in both BFO and B…
High-density ordered arrays of core–shell nano-pillars of Ag–perylene were fabricated using an anodic aluminium oxide (AAO) template which was first embedded with the perylene molecules, followed by an electrochemical deposition of Ag. The surface-enhanced Raman scattering (SERS) spectrum obtained from this system sho…
A kinetic model of the physicochemical processes occurring during the corrosion of steel covered by a thin water film exposed to a atmosphere is proposed. This model explains theoretically the unusual physicochemical behaviors generally observed in such confined corrosive media: supersaturations, low corrosion rates,…
The presented metamaterial consists of the matrix (magnesium diboride $\mathrm{Mg}{\mathrm{B}}_{2}$ in a normal state, at room temperature) with randomly (or regularly) embedded spherical nanoparticles of a polaritonic crystal, SiC. The calculations demonstrate explicitly that the metamaterial exhibits negative refrac…
Abstract Polymer clay nanocomposites (PCN) show enhanced mechanical, thermal, liquid or gas barrier properties in comparison to pure polymer. However, the mechanisms for enhancement of these physical properties of PCN are not well understood. This knowledge is important for tailoring the properties of PCN to desired s…

Phenolic resin-based activated carbon fibers (ACFs) were prepared by , , steam, , and ferrocene activation. The porosity, surface chemistry, and electric conductivity of ACFs were studied as electric double-layer capacitors in electrolyte. The specific capacitance for ACFs is generally in the range 130– and roughly ha…
Abstract Without any preprocessing, silk fabric has lower ability to hold on water due to the smooth morphology of silk fibers. Therefore, patterns directly printed with pigment inks have poor color yields and easily bleed. Plasma surface‐treatment of silk fabric was carried out in an oxygen atmosphere under different…
Rechargeable direct carbon fuel cells (RDCFC) can be expected as portable power sources. The performance of power generation from RDCFCs was investigated here for various Ar flow rates into the anode. The fuel of solid carbon was charged by thermal decomposition of pure dry methane on the anode. The power generation t…
The principal aim of this research study is to discuss the influences and effects of the acetylation degree of chitosan on antibacterial properties, mechanism, and thermal properties. Various chitosan with different degrees of deacetylation (DD%) were dissolved in acetic acid solution to produce films. The basic struc…
Abstract The ageing behavior due to the effects of heat, ozone, γ‐ radiation, and water on ethylene propylene diene monomer rubber/styrene butadiene rubber (EPDM/SBR) blends was studied. The tensile strength, crack initiation, ozone ageing, gamma radiation, and water resistance of the blends were measured and used to…
Abstract The effect of polymorphism of isotactic polybutene‐1 (iPB‐1) on the peel behavior of the specific peel system low‐density polyethylene/polybutene‐1 (LDPE/iPB‐1) was investigated using wide‐angle X‐ray scattering, calorimetry, and the T‐peel test. Melt‐crystallization of iPB‐1, initially, yields tetragonal for…

We propose a focal intensity tunable microlens array by using a birefringent liquid crystalline polymer for lensing action. Due to the difference of effective refractive indices, it acts as a positive or negative microlens with respect to the polarization state. As we control the incident polarization by adding a liqu…
Improved LIPOCEST MRI contrast agents with highly shifted intraliposomal water protons were prepared by entrapping neutral polynuclear Tm(III)-based paramagnetic shift reagents in phospholipidic vesicles.
Abstract The thermal degradation behavior of resol, several vegetable fibers (two types of cotton fibers, sisal and sugar cane bagasse) and derived polymer composites have been investigated using thermogravimetric analysis (TGA). The initial thermal degradation temperature T ONSET , the temperature at the maximum degr…
Dinuclear [(TPyA)FeII(THBQ(2-))FeII(TPyA)](BF4)2 (1) possesses hydrogen bonding interactions that form a 1-D chain, and pi-pi interactions between the 1-D chains that give rise to a 2-D supramolecular-layered structure, inducing hysteresis in the spin crossover behavior; 1 has shown spin crossover behavior around 250…
Solvatomorphism has been found between two series of complexes of the composition [M(bpy)3]2[NbO(C2O4)3]Cl.nH2O [M = Fe2+ (1, 2), Co2+ (3, 4), Ni2+ (5, 6), Cu2+ (7) and Zn2+ (8, 9); bpy = 2,2'-bipyridine)], crystallizing in the monoclinic space group P2 1/c [3, 5, 8 (n = 11)] or in the orthorhombic space group P21 21…
Polypyridyl-functionalized alkynes are a class of bifunctional ligands and very useful for the design of heteropolynuclear or multicomponent arrays as optoelectronic materials at the molecular level. This article focuses on reviewing the recent progress in design of luminescent heteropolynuclear or multicomponent comp…
