1. IntroductionThe imbibition of the wetting phase into porous media is a universalphenomenon in nature and is associated with many practical problems[1], such as water imbibition in soil [2], CO2 geo-sequestration [3], andproduction of crude oil [4].

Abstract: Hydrogen peroxide (H2O2 ) is one of the intermediates or fifinal products of biological metabolism and participates in many important biological processes of life activities. The detection of H2O2 is of great signifificance in clinical disease monitoring, environmental protection, and bioanalysis.

In this work, we synthesized functional hybrid aerogels with tailored functions for waterpurification application. It shows a few significances in environmental science. 1) Green synthesis of hybrid aerogels as adsorbents of contaminants was reported. 2) 2D graphene nanosheets were used to regulate the porous structure of polymer aerogels,and peptide-medicated biomineralization process was utilized to regulate the function ofaerogels, which enhanced greatly the adsorption capacity of hybrid aerogels towards heavymetal ions and organic dyes. 3) The synthesized hybrid aerogels exhibited better sustainability than other similar adsorbentsvia the Ranked Efficiency Products (REP) analysis.

The toxic activity of cur on macrophage RAW264.7 cell was determined in a 24 hourMTT (3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazoliumbromide) assay (cytotoxicity test) and we found that the cell viability of cur was not significantly decreased at all concentrations, ranging from 5 to 40 μg/mL, and more than 80% of cells survived. Based on these results, macrophage RAW264.7 cells were treated with cur (40 μg/mL) for 24 h.

Thin fifilms of (SiO2)xSb1-x (x ¼ 0.22, 0.28, 0.36, 0.40) were deposited on Si/SiO2 substrate at room temperature via cosputtering SiO2 and Sb pure targets. Sb fifilms were also prepared by sputtering Sb pure target for comparison.

The Er-doped Ge10Sb90 thin films of Erx(Ge10Sb90)1-x(0 B x B 0.024) were deposited on SiO2/Si (100)wafers by co-sputtering of Er and Ge10Sb90 targets atroom temperature using magnetron sputtering. Thepurity of Sb and Ge10Sb90 targets was 99.999%.

For the phase change memory (PCM) application, it is very desirable to possess better comprehensive performance in phase change materials, such as high stability, ultra-faster phase change and low power consumption.

The second part described about how to examine properties and structure of SnSe and CuSnSe films. The transition from amorphous to crystalline was researched by in situ temperature dependent conductivity and resistance measurement.

The amorphous-to-crystalline transition was investigated by insitu film resistance measurements under an Ar atmosphere.
