We report on studies of an inorganic electrolyte: LiAlCl4 in liquid sulfur dioxide. Concentrated solutions show a very high conductivity when compared with typical electrolytes for lithium ion batteries that are based on organic solvents. Our investigations include conductivity measurements and measurements of transfe…
We propose and analyze a compact polarizing beam splitter (PBS) based on a metal-insulator-metal (MIM) structure inserted into a multimode interference coupler (MMI). Owing to the MIM structure, the TE polarized state is reflected by the cut-off condition while the TM polarized state is transmitted by the surface plas…
The photostability and narrow emission spectra of nonorganic quantum dot fluorophores make them desirable detection methods for ultrasensitive and multiplexing in situ hybridization applications to identify genetic aberrances in morphologically preserved clinical tissue specimens. However, robustness and reliability h…
A series of physically cross-linked gelatin networks were prepared and the effects of salt concentration and chemical valence of the salt ions on the swelling properties of the gelatin gels were studied in detail. It was found that the swelling behaviors as polyelectrolytic or polyampholytic gels depended on the charg…
Abstract Cu–Ag bimetallic nanoparticles loaded on reduced graphene oxide nanocomposites (Cu–Ag/rGO NCs) were obtained through a facile chemical reduction method. The resulting Cu–Ag/rGO NCs exhibited good catalytic activity in reducing H2O2, with a fast amperometric response, i.e., less than 2 s. The linear detection…
We report the use of Al-doped ZnO (AZO) as the current spreading layer for AlGaInP-based light-emitting diodes (LEDs). It was found that AZO could form good ohmic contact with AuBe-diffused p-GaP. It was also found that the specific contact resistance could be further reduced from 2.68×10-4to 1.52×10-4Ω-cm2by performi…
A series of eight novel T-shaped chromophores with indan-1,3-dione central acceptor moiety and peripheral N , N -dimethylamino and thiophene donors were synthesized. 4,7-Diiodoindan-1,3-dione was prepared in a straightforward manner from phthalanhydride. Its modification with donors was accomplished by Knoevenagel, Su…
Vegetable oil-based dielectrics have been available for the past 15 years; relevant articles have been published [1]-[3]. One practical advantage of using a vegetable-oil dielectric in a power transformer is its higher affinity to moisture, around 20 times higher than that of mineral oil at room temperature [4]. Power…
The effect of shape anisotropy and size on the electronic structure of CdSe/ZnSe quantum dots is theoretically investigated. The quantum dot is modeled by assuming a parabolic confinement along xy plane and by finite well potential due to band offset along growth (z) direction. The energy eigenvalues and wave function…
The effect of temperature on the intrinsic viscosity and the Huggins coefficient of polyethylene glycol (PEG 35000) in aqueous solution was studied. The intrinsic viscosity became negative for temperatures higher than 45°C. Two hypotheses are given to explain this tendency. We demonstrated that the mobility and size o…
In this paper we present a general model for the dynamic behavior of multiphase systems in which the bulk phases and interfaces have a complex microstructure (for example, immiscible polymer blends with added compatibilizers, or polymer stabilized emulsions with thickening agents dispersed in the continuous phase). Th…
The application of patterned thin film layers of metal organic frameworks onto surfaces is a matter of much interest of late with a view toward opening exciting applications for MOFs in gas sensing and catalysis. Here, the use of a plasma polymer coating technique has been employed to selectively alter the surface che…
Nanopatterning of an ecofriendly antiglare film derived from biomass using an ultraviolet curing nanoimprint lithography is reported. Developed sugar-related organic compounds with liquid glucose and trehalose derivatives derived from biomass produced high-quality imprint images of pillar patterns with a 230-nm diamet…
Self-assembly of amyloid nanofiber is associated with both functional biological and pathological processes such as those in neurodegenerative diseases. Despite intensive studies, the stochastic nature of the process has made it difficult to elucidate a molecular mechanism for the key amyloid nucleation event. Here we…
Ultrafine particles (UFPs) are generally defined as those particles with a diameter less than 100 nanometer (nm) that are not intentionally generated (i.e., engineered nanoparticles). Sources of UF...
Abstract Magnetic graphene oxide functionalized with sulfonic acid (Fe3O4‐GO‐SO3H) was used as a new recyclable nanocatalyst for one‐pot synthesis of N‐aryl‐2‐amino‐1,6‐naphthyridine derivatives under solvent free conditions. The catalyst could be easily recovered from the reaction mixture by an external magnet and re…
ZnO-SnO2 nanoparticles were prepared by coprecipitation method; then Mg, with different molar ratios and calcination temperatures, was loaded on the coupled nanoparticles by impregnation method. The synthesized nanoparticles were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE…
A novel CoAl-hydrotalcite catalyst with different Co2+/Al3+ ratios was facilely synthesized using a modified coprecipitation method. Different techniques such as X-ray diffraction (XRD), Fourier transform-infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), and energy-dispersive X-ray (EDX) were used to…
The ambient temperature equation of state of ruby in the corundum phase ($\ensuremath{\alpha}$-Al${}_{2}$O${}_{3}$) has been measured up to 165 GPa in a diamond anvil cell, using a soft pressure transmitting medium. No clear sign of phase transformation or amorphization has been observed in this range, which could aff…
Many protein-protein docking protocols are based on a shotgun approach, in which thousands of independent random-start trajectories minimize the rigid-body degrees of freedom. Another strategy is enumerative sampling as used in ZDOCK. Here, we introduce an alternative strategy, ReplicaDock, using a small number of lon…
