Wang et al. [1] proposed strategies of popularizing and using green building materials, and indicated that with the rapid development of construction, green building materials have reached a certain level.
Varieties of material have been renovated and developed continuously, and new green building materials have continuously emerged.
As people pay increasing attention to green building materials, these will certainly replace traditional building materials.

Mesoporous silica materials seem to become ideal supports for Au nanoparticles due to regular pores and excellent surface modification abilities since the Mobil scientists first reported the M41S family of materials[9].
The synthesized materials were characterized by using scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD).
This modified materials Al-SBA-15 based on SBA-15 revealed good performance and would be further studied and reported.
And when CA and KBH4 were used as reductants, Au/SBA-15 materials shows great catalytic properties.

Journal Citation (to be inserted by the publisher) Copyright by Trans Tech Publications Application of La2O3-B2O3-TiO2 Glass-Ceramic for Low Temperature Co-Fired Ceramic (LTCC) Materials Byung-Hae Jung, Seong-Jin Hwang and Hyung-Sun Kim � Dept. of Materials Science and Metallurgical Engineering, Sunchon National University, Sunchon, 540-742, Korea, Keywords: LTCC, Glass-Ceramic, Microwave Dielectric Properties Abstract.
It is suggested therefore that this new composite has good potential as a new candidate for low temperature co-fired ceramic (LTCC) materials.
Therefore LTCC compatible materials with adjustable permittivities � r>20 are also needed [5].
When fabricating desirable LTCC materials within the middle permittivity range being used as a module type, (often the low softening temperature glass frits and single oxides), usually B2O3 is mixed with the ceramic materials to reduce the high firing temperature of the ceramic materials.
The raw materials for the glass frit were La2O3, H3BO3 and TiO2 which all have high purity (Aldrich, USA).

The selection of these materials allows to obtain a high corrosion resistance electrolytic pair, by replacing the high cost platinum electrode usually employed in the alkaline electrolysis process.
There are several materials that can be used as electrodes in alkaline electrolysis.
Platinum and gold are technically the most suitable materials to be used as electrodes.
Materials and Methods Reactor Project The objective of the electrolytic reactor project is to maximize the contact area of the electrodes with the electrolyte.

Experimental Materials The raw materials for preparation inorganic adhesive were dead burned magnesia, fly ash (FA) and phosphates.
The concrete materials mixture proportion was Portland cement:water:sand:aggregate in 1:0.48:2:2.8.
In order to select the best materials mixture of phosphate binder, extensive tests were carried out.
Finally, three best materials mixtures among the tests were confirmed, namely P1, P2 and P3 respectively.

ODS steels (Oxide Dispersion Strengthened) are candidate materials for fuel cladding in Sodium Fast Reactors (SFR).
These materials have good mechanical properties at high temperature due to a dispersion of nanometer-sized oxides into the matrix.
These materials are manufactured by powder alloying and contain nanometric particles of oxide which are anchors against dislocation movement improving the performance of these materials at high temperature.
