Introduction Geopolymer, first defined by Davidovits [1], should more appropriately be referred to as a type of inorganic polymer with three-dimensional network structure.
It can also be seen in Fig. 6(c) that the appearance of surface shows the best characteristic of continuous, less porous, homogeneous structure.

The chemical structure of Tecophilic® and sericin was shown in Figure 1.

The formation of Mn2O3 indicates that the temperature was not high enough to reach full crystallization and that some vacancies occurred in the LiMn2O4 structure during combustion [10].
The products show good crystallization and a stable structure.

Thus, from the IR analysis, it may be said that the hydrolysis degradation of epoxy networks occurs mainly due to the scission of the ether and ester bonds, and then combined with active hydrogen to form the stable structure.
Then the cracking of ether bond leads to the depolymerization of the whole network directly, which leads to the formation of phenols, the structure of bisphenol A can also be confirmed by GC-MS.

Design of Conductive MWNTs/SiO2 Humidity Sensor Interface ASIC Based on AC Signals Li Tuo1, a, Liu Xiaowei1, 2, Yin Liang1, 2, Dong Changchun1, 2 1 Department of Microelectronics, Harbin Institute of Technology, Harbin, Heilongjiang, China 2 Key Laboratory of Micro-Systems and Micro-Structures Manufacturing, Ministry of Education, China alituo251314@163.com Keywords: multiwall carbon nanotubes (MWNTs); humidity sensor; interface; AC signal Abstract.
Novel material carbon nanotubes (CNTs) turn out as great sensing materials for miniature sensors in biology and chemistry, especially for gas and humidity detection [1-3].
However, when the sensor is given AC signals, the thin film structure equals to a parallel connection of a kΩ level resistance and nF level capacitance, and they both appear sensitive to humidity.

Existing researches on the absorbing properties of cement-based materials show that adding nano-materials can improve the performance of wave absorbing, 10-15mm thick samples made from cement mixed with nano-TiO2 powder were found very effective within 2-18GHz spectrum.[6-9] In this paper, the electromagnetic wave absorption performance of modified cement base material were studied, this research has important academic value in the development of large span structures’ camouflage technology, and improving stealth properties of concrete structures, etc.

Polyphenols scavenge free radicals collaborating with other antioxidants and metals [6], which possess the ideal chemical structure for scavenging free radicals.
The highest radical scavenging activity is exhibited by compounds that have an ortho 30, 40 - dihydroxy structure at ring B (e.g. catechin, quercetin) or hydroxyl groups in position meta, e.g. 5, 7 - dihydroxy at ring A (e.g. kaempferol, apigenin), as well as those that have a double bond between the C2 and C3 and the C3 - hydroxyl group at ring C.

Introduction Stable mixed ionic and electronic conducting oxides with the fluorite structure are attracting interest as candidates to be used as electrodes (mainly as anodes) in several applications, such as in solid oxide fuel cells (SOFC), oxygen separation membranes and electrocatalysts for the partial oxidation of hydrocarbons [1,2].
So the 8TiYSZ powder prepared by co-precipitation combined with azeotropic distillation was a kind of nano-powders with the structure of uniform solid solution.

Currently, the most common coating for actual clinical application is hydroxyapatite coating plasma sprayed onto titanium alloys at high temperatures near 10,000 ºC, but problems often occur in controlling the composition, crystallinity and structure of hydroxyapatite.
