Introduction: Based on the comparative and analytical studies on the research work conducted on the damage mechanism and mechanical property of the composite structure after exposure to fire, the research method and the research achievements are summarized and reviewed. Results and Conclusion: The achievements are mainly obtained from the studies on the beam (floor-slab) component, beam-column joints and the frame structure by the means of the axial compression static experiment or quasi static experiment in the past. Finally, some issues that still need to be studied are also discussed from three prospects.

AbstractThe conformal coating of ZnO nanorods with CdTe nanoparticles using layer-by-layer (LbL) processing produces a quantum dot-sensitised solar cell. As the number of CdTe layers increases the absorption of incident light increases below the absorption onset of the nanoparticles (650 nm). Photoluminescence investigations of the CdTe-ZnO composite structure suggest a transfer of photoexcited electrons from the CdTe nanoparticles the ZnO nanorods. Filling of the semiconductor composite structure with CuSCN provides the solar cell with a p-type semiconductor to collect the photogenerated holes from the system. Annealing the CdTe-polymer coated nanorods lowers the series resistance of the cell by removing the polymer component of the film. A cell annealed at 350 °C has aJscof 0.12 mAcm-2, and aVocof 49 mV under 0.25 mW/cm2illumination.

Cellular Matrix

Modeling of interactions between cell and extra cellular matrix (ECM) is essential in a cell and tissue injury study. Several studies have been conducted to realize the role of mechanical property of a cell and ECM in a tissue exposed to an external loading. In this study we have used a micromechanical approach by assuming two representative volume elements (RVE) with different packing of cell inside the matrix to characterize the mechanical property of the composite formed by the cell and the ECM in a tissue. In the micromechanical modeling procedure, the cell-ECM adhesion will be studied in detail. The results will clarify the role of cell adhesion in load transferring characteristics inside the cell – ECM composite.

Although it is recognized that niacin (pyridine-3-carboxylic acid), incorporated as the amide in nicotinamide adenine dinucleotide (NAD) or in nicotinamide adenine dinucleotide phosphate (NADP), is a cofactor in hydrogen transfer in numerous enzyme reactions in all organisms studied, virtually no information is available on the effect of this vitamin on a cell at the submicroscopic level. Since mitochondria act as sites for many hydrogen transfer processes, the possible response of mitochondria to niacin treatment is, therefore, of critical interest.Onion bulbs were placed on vials filled with double distilled water in the dark at 25°C. After two days the bulbs and newly developed root system were transferred to vials containing 0.1% niacin. Root tips were collected at ¼, ½, 1, 2, 4, and 8 hr. intervals after treatment. The tissues were fixed in glutaraldehyde-OsO4 as well as in 2% KMnO4 according to standard procedures. In both cases, the tissues were dehydrated in an acetone series and embedded in Reynolds' lead citrate for 3-10 minutes.
