TiO(2) is one of the most studied compounds in materials science. Owing to some outstanding properties it is used for instance in photocatalysis, dye-sensitized solar cells, and biomedical devices. In 1999, first reports showed the feasibility to grow highly ordered arrays of TiO(2) nanotubes by a simple but optimized electrochemical anodization of a titanium metal sheet. This finding stimulated intense research activities that focused on growth, modification, properties, and applications of these one-dimensional nanostructures. This review attempts to cover all these aspects, including underlying principles and key functional features of TiO(2), in a comprehensive way and also indicates potential future directions of the field.

Degeneration and regeneration of the nervous system

Fibroblasts can condense a hydrated collagen lattice to a tissue-like structure 1/28th the area of the starting gel in 24 hr. The rate of the process can be regulated by varying the protein content of the lattice, the cell number, or the con- centration of an inhibitor such as Colcemid. Fibroblasts of high population doubling level propagated in vitro, which have left the cell cycle, can carry out the contraction at least as efficiently as cycling cells. The potential uses of the system as an immu- nologically tolerated "tissue" for wound hea ing and as a model for studying fibroblast function are discussed.

Cross-section of multi-layer InAs/GaAs quantum dot heterostructure has been characterized using scanning capacitance microscopy to investigate dopant incorporation into quantum dots. Simulation of the corresponding band structure is used to better understand the experimental results.

Doping Characterization of InAs/GaAs Quantum Dot Heterostructure by Cross-Sectional Scanning Capacitance Microscopy

Nowadays, due to the increasing demand on portable electronic devices with ultrahigh density data storage and lower power consumption, the miniaturization of ferroelectrics has become an important issue. This progressive development requires the morphology control of the materials and the understanding of the effects of size reduction on the properties at the nanoscale, namely ferroelectric properties.

Porosity… Advantage or Disadvantage?

The electric forces acting on an atomic force microscope tip in solution have been measured using a microelectrochemical cell formed by two periodically biased electrodes. The forces were measured as a function of lift height and bias amplitude and frequency, providing insight into electrostatic interactions in liquids. Real-space mapping of the vertical and lateral components of electrostatic forces acting on the tip from the deflection and torsion of the cantilever is demonstrated. This method enables direct probing of electrostatic and convective forces involved in electrophoretic and dielectroforetic self-assembly and electrical tweezer operation in liquid environments.

Ferroelectricity in Synthetic Biomaterials: Hydroxyapatite and Polypeptides

Among the various possible routes towards solid-state non-volatile random access memories (NV-RAMs) of high memory density, ferroelectric random access memories (FRAMs) offer very good prospects. Non-volatility is provided by the ionic character of the signal, and switching by an electric field is sufficiently fast and free from crosstalk.
