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…
Te-free environmental friendly SiSb phase-change material is investigated for the applications of phase-change memory. The binary material, which is compatible with the complementary metal-oxide semiconductor manufacturing process, is outstanding in various properties comparing with the most widely adopted ternary Ge2…
Epitaxial quantum dots with symmetric and highly facetted shapes are fabricated by thermal annealing of two-dimensional (2D) PbTe epilayers embedded in a CdTe matrix. By varying the thickness of the initial 2D layers, the dot size can be effectively controlled between 5 and 25nm, and areal densities as high as 3×1011c…
A high-crystallinity, low-resistance Pr0.7Ca0.3MnO3(PCMO) thin film deposited by sputtering at 600°C showed no resistive switching with a Pt∕Pr0.7Ca0.3MnO3∕Pt structure but a remarkable bipolar resistive switching with a Ag paste/Pr0.7Ca0.3MnO3∕Pt structure. Observed retention fatigue of the low-resistance state was a…
The dielectric properties show a typical ferroelectric relaxor behavior in CaCu3Ti4O12 ceramics with different grain sizes in the temperature range of 400–600K. The relaxation strength and the frequency dispersion increase with grain size decreasing, which can be due to the different stresses in grains with different…
Raman spectra of individual carbon nanotubes are measured by scanning a focused laser spot (0.5μm diameter) over a large area (100μm2) before and after depositing silver nanoparticles. Local regions exhibiting surface enhanced Raman spectroscopy (SERS) were located with respect to a lithographically patterned grid, al…
Superhydrophobic TiO2 nano-strawberry rutile films, on which superhydrophobicity and superhydrophilicity can be reversibly switched by alternation of ultraviolet (UV) irradiation and dark storage, were fabricated on a large scale from aqueous solution via a seeded growth method at low temperature without any pressure…
