In this paper we investigate the motion of molecules in crowded environments for two dramatically different types of molecular transport. The first type is realized by the dynamic lattice liquid model, which is based on a cooperative movement concept and thus, the motion of molecules is highly correlated. The second o…
The emission intensity of <bold>DPA</bold> can be efficiently switched by fluorescence resonance energy transfer between the energy donor <bold>DPA</bold> and acceptor <bold>1b</bold> .
A reliable thermal interface material (TIM) typically has a low storage modulus (G') and a tan(δ) less than one; these mechanical properties are crucial for minimizing contact resistance (Rc). This paper demonstrates the correlation between storage modulus (G') and the crosslink density of silicone gels. Formulations…
coordination driven one dimensional (1D) smart supramolecular helical assembly of a new heteroditopic ligand was achieved. Moreover, thermo- and chemo-responsive transformation/disassembly/reassembly of the helical superstructure was also demonstrated.
An interesting centrosymmetric to noncentrosymmetric structure transformation from Ba <sub>8</sub> Ga <sub>2</sub> Sn <sub>7</sub> Se <sub>18</sub> to Ba <sub>10</sub> Ga <sub>2</sub> Sn <sub>9</sub> Se <sub>22</sub> induced by isolated dimeric [Sn <sub>2</sub> Se <sub>4</sub> ] units was reported.
In this work, the thermal properties of nanoscale SiO2 thin films have been systematically investigated with respect to the thickness, crystal orientations and the void defects using non-equilibrium molecular-dynamics (NEMD) simulation. Size effect for the lattice thermal conductivity of nanoscale SiO2 thin films was…
To effectively use the entire solar spectrum for energy conversion, a new type of solar cell based on a Bi <sub>2</sub> Te <sub>3</sub> /CdTe composite in a core shell structure was designed and prepared using a wet chemical method.
ZnO and carbon mixture as dual-emission ratiometric fluorescent sensor of acid rain have been demonstrated.
a.u. obtained with a relatively larger basis set established the earlier prediction of Sadlej et al. [Phys. Chem. Phys. Chem., 2000, 2, 3393-3399] where degenerate non-dipolar transitions in low lying excited states play the crucial role. The successive lithiation results in gradual red shifting of transition energy l…
Microbial induced corrosion (MIC) or biocorrosion is one type of corrosion, directly or indirectly influenced by microbial activities, by forming biofilm and adhering on the metal surface. When forming biofilm, the microorganisms can produce extracellular products which influence the cathodic and anodic reactions on m…
Wood plastic composites (WPCs) have often been used in consumer applications, automotive industry and exterior construction. WPCs consist mostly of wood and thermoplastic polymer. WPCs can have superior outdoor durability and much lower maintenance costs than regular wood. WPCs can be used instead of wood. Styrene mal…
We report remarkable stability of Pt crystals supported on {111} facet of ZnAl <sub>2</sub> O <sub>4</sub> under harsh oxidizing atmosphere, we also identified segregation of ZnAl <sub>2</sub> O <sub>4</sub> to ZnO and Al <sub>2</sub> O <sub>3</sub> and formation of PtZn for Pt supported on other facets of ZnAl <sub>2…
molecule on the h-BN sheet deposited on Ni, Co, or Cu substrate were almost spontaneous with negligible energy barrier, distinctly different from that on the freestanding h-BN sheet, which has ultra-high chemical stability. In particular, the enhanced oxidation of h-BN sheet can be confined in the nanoscale region due…
The introduction of a dicyanomethyl anion group to hexa-peri-hexabenzocoronene (HBC) substantially enhanced the emission properties of HBC due to a large perturbation of its electronic structure. In addition, dicyanoetheno-bridged HBC dimers obtained from oxidation of a dicyanomethyl HBC anion exhibited bright red emi…
Despite increasing biomedical applications of zinc oxide nanoparticles (ZnO NPs), there is a lack of information concerning the biological effects of ZnO NPs on human cells. The purpose of this study was to assess the comparative cytotoxicity in human prostate cells (PC-3 and RWPE-1) exposure to 20-nm ZnO NPs. Exposur…
We have studied the phase behavior of polydisperse Yukawa hard-sphere fluid confined in random porous media using extension and combination of high temperature approximation and scaled particle theory. The porous media are represented by the matrix of randomly placed hard-sphere obstacles. Due to the confinement, poly…
Addition of 2 equiv. of CuI to a [Cu] <sub>4</sub> multimetallic complex results in cluster formation leading to the isolation of a rare bicapped tetrahedral [Cu <sub>6</sub> I <sub>2</sub> ] cluster that is stabilised by two conformationally constrained polynucleating ligands.
FTO thin films were prepared by the hydrothermal method at anneal temperature of 100°C-400°C using pentahydrate stannic chloride (SnCl4.5H2O) and ammonium fluoride (NH4F) as precursors, and a mixture of DI water, acetone and hydrochloride as a solvent. The X-ray diffraction studies confirmed the tetragonal structure w…
In order to precisely investigate molten core relocation behavior in severe accidents, we have been developing the detailed and phenomenological numerical simulation code named JUPITER for predicting the molten core behavior with melting and solidification based on computational fluid dynamics (CFD) including the thre…
The immediate customers of cotton gins are the producers; however, the ultimate customers are textile mills and consumers. The ginner has the challenging task to satisfy both producers and the textile industry. Classing and grading systems are intended to assign an economic value to the bales that relates to textile m…
