From this, nanotubes with a diameter of ~240 nm and wall thickness of ~20 nm (figure 6b) and nanowires with a diameter of ~60-260 nm were produced (figure 5a & c).[41] 0 50 100 150 200 250 300 350 400 450 2 4 6 8 10 Crystalline Size (nm) Heat Treatm ent Tem perature ( oC) TiO2 xerogel (Ti,Sn)O2 xerogel Figure 4 - (A): Raman spectra of commercial anatase TiO2 [38] (a), TiO2 xerogel (b), and TiO2 xerogel heat-treated at 200 °C (c), 400°C (d), 600 °C (e), 800 °C (f), and 1000 °C (g), (B): Adapted graph from the XRD data table 1 from [40] B A Figure 5 - TEM images of titania: (a) nanowire and (b) nanotube synthesized inside commercial AAO templates; (c) nanowire synthesized inside a prepared AAO template. [41] Other templating methods have made use of anodic alumina membranes (AAMs) as templates to synthesize highly ordered films, nanowires and nanotubes.
In addition, the formation of nanorods and nanofibres is energetically favoured by the reduction of surface interfacial energies. 5.

The purified proteins were applied as cell-coating materials (termed as cell-cooking plate) to support experimental cells, and various biophysical and biological parameters were measured in comparison with standard as well as other experimental systems to acquire data, which were then compared and the conclusions were drawn.
This type of cooking-plate technology, where E-cad-Fc provides basal support to the cells and other immobilized factors satisfy specific needs, can be extremely beneficial for (1) ensuring undifferentiated state of stem cell in culture, (2) cost reduction associated with cytokines, and (3) hassle-free working condition without the necessity of regular media change, which is a standard practice for stem cell culture and a stress factor for the relevant people.

Since there is no published data for 2D-FG micro/nanobeams including the simultaneous effects of surface energy and modified couple stress, the present results of bending and buckling behaviors are compared with some limiting cases available in the literature. 3.1.1 Validation of static bending The dimensionless center deflection of a simply-supported homogeneous microbeam with E=1.44 GPa, ν=0.38, h=88 μm, L=20h and b=2h and subjected to a uniformly distributed load of unit intensity q is presented in Table 2, based on the MCST and compared with Reddy [100] and Arbind and Reddy [101] for different values of the dimensionless material length parameter (l/h).
Such assumption is due to that there is no experimental data in the literature for the material length scale parameter of bi-directionally functionally graded materials l(x,zm) or of silicon (lSi).

In practice it is understood that the reduction is enhanced in borate anionic networks under mild-reducing atmospheres when compared to phosphate or aluminate networks.
The spectroscopic data indicate that the Eu 2+→ Mn2+ energy transfer process takes place in the host matrix of CaAl2Si2O8.
The photoluminescence results were correlated with the lifetime data to get an insight into the luminescence and energy transfer processes taking place in the system.

This blue shift could be attributed to the size reduction effect of PVA matrix to CdSe nanorods.
Experimental data has shown that the thermionic emission theory is a better approximation than the diffusion theory [104].

Understanding the manner in which damage evolves in engineering materials, systems or structures is currently the focus of extensive research. The object of the present book is to report recent advances in the areas of damage detection, assessment and quantification. All aspects of the topic are covered, ranging from detailed theoretical analyses to case studies of full-scale structures. Signal processing is still an important theme of the conference. However, some of the emphasis is now placed on damage mechanisms in materials. Also of vital importance, for structural health and condition monitoring, is the optimum choice of measurement strategy; including the specification of sensors.

The 2011 International Conference on Materials Engineering for Advanced Technologies was held on May 5-6, 2011, in Singapore. The objective of the conference was to bring together researchers from academia and industry, as well as end-users, in order to share ideas, problems and solutions related to the multifaceted aspects of Materials Engineering for Advanced Technologies. The resultant timely overview will be appreciated by anyone involved in these fields.
