Hydrogen adsorption has been studied in the nanoporous metal-benzenedicarboxylate M(OH)(O2C-C6H4-CO2) (M = Al3+, Cr3+); these solids show a hydrogen storage capacity of 3.8 and 3.1 wt.% respectively when loaded at 77 K under 1.6 MPa.
The capacitance measured in dye-sensitised nanocrystalline TiO2 solar cells (DSSC) is interpreted in terms of a chemical capacitance, which is found to be a crucial feature for describing the dynamic operation of solar cells based on nanoscaled materials.
Two types of photomodulation of orientations of liquid crystals (LCs) are reviewed: 1) order–disorder phase transitions of LCs induced by photochemical reactions of photochromic molecules and 2) order–order alignment change of LCs (change in LC directors) induced by photochemical reactions or without photochemical eve…
Bilbao Crystallographic Server is a web site with crystallographic programs and databases available on-line. The programs give access to general information related to space groups (generators, general positions, Wyckoff positions, irreducible representations), group-subgroup or group-supergroup pairs of space groups,…
Nb, Ta and Zr are the favorable non-toxic alloying elements for titanium alloys for biomedical applications. Low rigidity titanium alloys composed of non-toxic elements are getting much attention. The advantage of low rigidity titanium alloyfor the healing of bone fracture and the remodeling of bone is successfully pr…
Development of biologically inspired experimental processes for the synthesis of nanoparticles is an important branch of nanotechnology. In this paper, we report on the use of geranium leaves (Pelargonium graveolens) and its endophytic fungus in the extra-cellular synthesis of gold nanoparticles. Sterilized geranium l…
Development of biologically inspired experimental processes for the synthesis of nanoparticles is evolving into an important branch of nanotechnology. In this paper, we report on the use of Geranium (Pelargonium graveolens) leaf extract in the extracellular synthesis of silver nanoparticles. On treating aqueous silver…
Provides a basis for understanding the characteristics, operation, and limitations of semiconductor devices. This title deals with the electrical properties and characteristics of semiconductor materials and devices. It intends to bring together quantum mechanics, the quantum theory of solids, and semiconductor materi…
In the most general sense, biomineralization is a process by which organisms produce materials solutions for their own functional requirements. Because so many biomineral products are derived from an initial solution phase and are either completely crystalline or include crystalline components, an understanding of the…
A new synthesis route to high-quality large mesoporous cubic Ia3d silica is reported, utilizing a triblock copolymer (EO20PO70EO20)-butanol mixture for the structure direction in aqueous solution.

This paper presents the results obtained on the electrochemical behavior of electrochemical capacitors assembled in nonaqueous electrolyte. The first part is devoted to the electrochemical characterization of carbon-carbon 4 cm 2 cells systems in terms of capacitance, resistance, and cyclability. The second part is fo…
The inhibition mechanism of the Cashew Nut Shell Liquid (CNSL) on SAE 1008 carbon steel corrosion in CO 2 saturated 3% NaCl solutions has been studied by weight loss, UV/VIS and electrochemical techniques. The phenoxide, R-Ar-O- ions from the CNSL inhibitor were found to be responsible for the reduction of the corrosi…

We show that the fabrication of one-dimensional Si nanostructures with tailored electronic structure and optical properties can be achieved by encapsulating magic metal-doped Si clusters in carbon nanotubes. This cannot only effectively change the properties of the so-called peapod, but also can keep the intrinsic str…
From the unique library of molybdenum-oxide based building blocks/fragments under reducing conditions in aqueous solution a huge variety of nanoobjects, allowing specific reactions at well-defined positions, can be generated. This enables us to perform a new type of nanochemistry. Examples include the well-known molec…
The half-doped manganite perovskite ${\mathrm{TbBaMn}}_{2}{\mathrm{O}}_{6}({\mathrm{Tb}}_{0.5}{\mathrm{Ba}}_{0.5}{\mathrm{MnO}}_{3})$ has been prepared by low-temperature oxygen intercalation into ${\mathrm{TbBaMn}}_{2}{\mathrm{O}}_{5}.$ Neutron powder diffraction shows that at 300 K, ${\mathrm{TbBaMn}}_{2}{\mathrm{O}…
The structural relaxation of a glass-forming simple liquid, 3-methylpentane, is studied by triplet state solvation dynamics as a function of the distance from the surface in porous silica. By bonding the optical probes to the pore surface, we observe interfacial dynamics which are 3 orders of magnitude slower compared…
