The objective following of the present study was to investigate the effect of different storage time and conditions on the stability of lactide. In this study the samples of lactide with different purities were stored under three various storage conditions and the compound integration was monitored for a period of 2 w…
DFT calculations predict two different electronic structures of metal-molecule hybrids which are selected depending on the surface charge. While the metal-to-molecule CT states are very sensitive to the charge, the energies of the reverse molecule-to-metal CT processes are surprisingly not modified at all by the charg…
The present paper examines the thermal effect on axially compressed buckling of a multiwalled carbon nanotube based on the gradient elasticity theories. The small-size effect, which plays an essential role in the buckling behavior with large aspect ratios under axial compression coupling with temperature change, is ca…
The discovery of a large thermopower in cobalt oxides in 1997 lead to a surge of interest in oxides for thermoelectric application. Whereas conversion efficiencies of <em>p</em>-type oxides can compete with non-oxide materials, <em>n</em>-type oxides show significantly lower thermoelectric performances. In this contex…
Abstract Novel biodegradable dendritic contrast agents (DCAs) based on polyester dendrimers were synthesized and characterized. The DCAs were stable at acidic pH, but hydrolyzed rapidly at physiological pH, which rendered the DCA's long‐term Gd 3+ retention as low as that of small molecule CAs. Their longitudinal rela…
Study effect of pH values, ionic strength and temperature on assembly behavior of quaternized cellulose and carboxymethyl cellulose.
A supramolecular hydrogel is synthesized on the basis of L-cysteine and silver nitrate with incorporated silver nanoparticles (SNPs), which are stabilized by L-cysteine. The steps in the synthesis and the structure and properties of the new system are investigated.
In this study, human foreskin fibroblasts and mouse embryonic fibroblasts were encapsulated in mechanically reversible, THEOS and THEOS-PEG gels that completely immobilized them restricting their motility, growth and proliferation. The changes in the membrane integrity and metabolic activity (MA) of the immobilized ce…
A one-dimensional continuum model related to close-packing theory has been developed to produce insights into the oxygen reduction reaction (ORR) process in a dense LSM-type cathode system. By incorporating SOFC cathode particle size, the modeling simulations reveal detailed surface processes and parallel reaction pat…
Cellulose sheets were grafted with several acrylic polymers, first globally through a dipping procedure and then locally by inkjet printing.
Dissolving zinc tetraphenylporphyrin in the tetraalkylphosphonium chloride ionic liquid P4448Cl results in progressive demetallation of the solute and quantitative production of the free base porphyrin. Aggregation of the free base occurs in which the monomer and J aggregates are in fully reversible thermal equilibriu…
The excitonic emission of the Cu <sub>2</sub> O nanowires are demonstrated, and a visible white light is observed for the first time.
This paper presents the mechanical properties of carbon nanocone-based polymer composites in the presence of interphase layer. Some representative volume elements are considered to study the elastic behaviors of the transversely isotropic nanocomposite and the effects of the interphase layer on four of five independen…
Cu <sup>2+</sup> ions induce the change in the morphology of self-assembled benzimidazole <italic>N</italic> -glycosylamines from nano-fibers to nano-spheres.
In the present work, multiferroic (1-x) BiFeO3-x (CoFe2O4) ( x=0, 0.3, 0.5) nanocomposite thin films were prepared by sol-gel spin coating process. Structural, electrical and magnetic properties of nanocomposite thin films have been studied. X-ray diffraction study confirmed the co-existence of both perovskite BiFeO3(…

An empirical model to estimate the ballistic velocity limit (BLV) for ceramic/metal bi-layer armour materials is proposed by considering momentum and energy balance during impact process. Impact simulations of different combinations of various thicknesses and materials for front ceramic and backing metallic layers and…
A remarkably high value of specific capacitance of 450 F/g is observed through electrochemical measurements in the electrode made of multiferroic Bismuth Ferrite (BFO) in the form of nanorods protruding out. These were developed on porous Anodised Alumina (AAO) templates using wet chemical technique. Diameters of nano…
GaN nanowires are being pursued for optoelectronic and high-power applications. In either use, increases in operating temperature reduce both performance and reliability making it imperative to minimize thermal resistances. Since interfaces significantly influence the thermal response of nanosystems, the thermal bound…
Redox-switchable second-order nonlinear optical (NLO) responses of a series of ferrocene-tetrathiafulvalene (Fc–TTF) hybrids have been studied based on density functional theory calculations.
