Multidrug resistance (MDR) is a major obstacle to successful clinical cancer chemotherapy. A novel doxorubicin anti-resistant Stealth liposomes (DARSLs), prepared by co-encapsulating doxorubicin (DOX) and verapamil (VER) into stealth liposomes, has been developed. The average particle size of DARSLs was 118.1+/-22.3 n…
The protonic-electronic mixed conductors are of great interest for their potential applications particularly for the hydrogen separation that is essential for hydrogen production from hydrocarbons. This paper deals with the mixed conduction properties of in which Ru is partially substituted for Ce in the high-temperat…
A nonvolatile 64-Mb 1T1R phase-transition random access memory (PRAM) has been developed by fully integrating chalcogenied storage material (GST: Ge/sub 2/Sb/sub 2/Te/sub 5/) into 0.18-/spl mu/m CMOS technology. To optimize SET/RESET distribution, 512-kb sub-array core architecture was proposed, featuring meshed groun…
Tinkering takes a fresh look at early automotive design from the bottom up, as a process that included manufacturers, engineers, designers, advice experts, and consumers, from savvy buyers to grass-roots inventors.

We demonstrate that guided resonant modes can be readily observed in asymmetrical photonic crystal slabs on high-index substrates. In spite of the high radiative loss associated with all optical modes in these cases, the guided resonant modes are found to give rise to strong high-Q features in the transmission spectra…
In this study, the electrical conductivity of undoped cerium oxide is evaluated using impedance spectroscopy. We have observed a new phenomenon, which is not related to electrode response but probably to diffusion processes in the grain boundary. An equivalent circuit has been constructed based on the observation, and…
A cell which consists of a porous 18 μm thick Y-doped (YSZ) electrolyte vol % open porosity) on a NiO-YSZ anode substrate and a cathode using has been investigated in the single-chamber configuration. The cell performance and catalytic activity of the anode was measured in a flowing air-methane gas mixture with variou…
A metallosupramolecular coordination polyelectrolyte prepared by the reaction of cobalt(II) with a novel bisterpyridine ligand has been assembled as the active component in electrochromic films by sequential deposition using electrostatic layer-by-layer self-assembly.
Diatoms are unicellular algae with silicified cell walls, which exhibit a high degree of symmetry and complexity. Their diversity is extraordinarily high; estimates suggest that about 10(5) marine and limnic species may exist. Recently, it was shown that diatom frustules are mechanically resilient, statically sophisti…
Experimental observations on the B4 phase of liquid crystal mixtures formed from bent-core (P-8-O-PIMB) and rod (5CB) achiral molecules reveal the stabilization of the B4 phase with an unusually large size of chiral domains. The phenomenon is interpreted as an intrinsic property of the B4 phase when arising below the…
Collagen, a large insoluble protein with a characteristic triple helical structure, is found as the most prominent component of extracellular matrix. The functions of collagen are not limited to providing mechanical strength to various tissues and organs as a structural protein, as it has been pointed out that collage…
In this article, we review some of our recent work on the development and study of the properties of self-organizing supermolecular liquid crystalline dendritic materials. Prior to this purpose, the state of the art in the field of molecular design, structure and properties of liquid-crystalline dendrimers (LCDs) will…
New materials are presented, derived from the original banana compounds where the first smectic phases with polar switching (SmCP) were detected. Our results demonstrate that the introduction of lateral substituents on the central ring (F, Cl, CN, NO2, CH3) and/or on the terminal rings (Cl, Br, CH3) can significantly…
The hydrothermal synthesis of three new vanadoborate compounds with elliptical (V10B28O74H8) clusters is described. The clusters contain pairs of bimetallic Zn2 or Mn2 units.
A novel organic electro-optic (EO) modulator using transparent conducting oxides (ZnO and In2O3) as electrodes is demonstrated for the first time. The modulator employs the poled guest-host chromophore/polymer material AJL8/APC having r33=35pm/V and is able to achieve a low Vpi=2.8 V switching voltage for an 8mm-long…
The paper discusses some unresolved issues in the solid state chemistry of alkali metal aluminohydrides (alanates) relevant to high-capacity hydrogen storage. Analysis of experimental data available in chemical and materials science literature suggests a one-step mechanism for the thermal decomposition of both pure an…
When biomaterials are inserted in a biological environment, for instance in a body implant, proteins do quickly adsorb on the exposed surface. Such process is of fundamental importance, since it directs the subsequent cell adhesion. Here we review recent advances in this field obtained with molecular simulations. Whil…
<title>Abstract</title> The morphological characteristics, biochemical composition, taxonomic composition and diversity, as well as the colonization process and sloughing and recolonization of periphyton are reviewed. The proximate composition of periphyton grown on different substrates in different habitats, and a li…
Conformal atomic layer deposition (ALD) on as-grown suspended single-walled carbon nanotubes (SWNTs) is not possible due to the inertness of ALD precursor molecules to the SWNT surface. Here, we present a functionalization technique that makes SWNTs reactive with ALD precursors, and deposit high-κ oxides ( Al 2 O 3 an…
