compressed earth blocks (cEB) are an alternative to cement blocks in the construction of wall masonry. However, the optimal architectural construction methods for adequate thermal comfort for occupants in hot and arid environments are not mastered. This article evaluates the influence of architectural and constructive modes of buildings made of cEB walls and concrete block walls, to optimize and compare their thermal comfort in the hot and dry tropical climate of Ouagadougou, Burkina Faso. Two identical pilot buildings whose envelopes are made of cEB and concrete blocks were monitored for this study. The thermal models of the pilot buildings were implemented in the SketchUp software using an extension of EnergyPlus. The models were empirically validated after calibration against measured thermal data from the buildings. The models were used to do a parametric analysis for optimization of the thermal performances by simulating plaster coatings on the exterior of walls, airtight openings and natural ventilation depending on external weather conditions. The results show that the cEB building displays 7016 hours of discomfort, equivalent to 80.1% of the time, and the concrete building displays 6948 hours of discomfort, equivalent to 79.3% of the time. The optimization by modifications reduced the discomfort to 2918 and 3125 hours respectively;i.e. equivalent to only 33.3% for the cEB building and 35.7% for the concrete building. More study should evaluate thermal optimizations in buildings in real time of usage such as residential buildings commonly used by the local middle class. The use of cEB as a construction material and passive means of improving thermal comfort is a suitable ecological and economical option to replace cementitious material.

The process of mixed rare earth metal (REM) conversion coating on aluminum alloy LY12 (2024) was introduced. The corrosion resistance of mixed REM conversion coating was examined by using weight loss test and electrochemical method. The results show that the mixed REM conversion coating increases the corrosion resistance of the alloy surface. Examination result of scanning electron microscope (SEM) shows that the coating exhibits honeycomb-like feature. x-ray diffraction (xRD) analysis reveals that the coating is amorphous. The result of x-ray photoelectron spectroscopy (xPS) indicates that mixed REM conversion coating consists predominantly of ce and O. The contents of other rare earth elements (La, Pr) are relatively low.

A multi-shot target assembly and automatic alignment procedure for laser–plasma proton acceleration at high repetition rate are introduced. The assembly is based on a multi-target rotating wheel capable of hosting more than 5000 targets,mounted on a 3D motorized stage to allow rapid replenishment and alignment of the target material between laser irradiations. The automatic alignment procedure consists of a detailed mapping of the impact positions at the target surface prior to the irradiation that ensures stable operation of the target, which alongside the purpose-built design of the target wheel, enables operation at rates up to 10 Hz. Stable and continuous laser-driven proton acceleration at 10 Hz is demonstrated, with observed cut-off energy stability about 15%.

cO_2 adsorption using TiO_2 composite polymeric membranes:A kinetic study

Journal of Environmental Sciences 2015年第9期27卷 163-171页

cO2is the main greenhouse gas which causes global climatic changes on larger scale. Many techniques have been utilised to capture cO2. Membrane gas separation is a fast growing cO2 capture technique, particularly gas separation by composite membranes. The separation of cO2 by a membrane is not just a process to physically sieve out of cO2 through the controlled membrane pore size. It mainly depends upon diffusion and solubility of gases, particularly for composite dense membranes. The blended components in composite membranes have a high capability to adsorb cO2. The adsorption kinetics of the gases may directly affect diffusion and solubility. In this study, we have investigated the adsorption behaviour of cO2 in pure and composite membranes to explore the complete understanding of diffusion and solubility of cO2 through membranes. Pure cellulose acetate（cA） and cellulose acetatetitania nanoparticle（cA-TiO2） composite membranes were fabricated and characterised using SEM and FTIR analysis. The results indicated that the blended cA-TiO2 membrane adsorbed more quantity of cO2 gas as compared to pure cA membrane. The high cO2 adsorption capacity may enhance the diffusion and solubility of cO2 in the cA-TiO2 composite membrane, which results in a better cO2 separation. The experimental data was modelled by Pseudo first-order, pseudo second order and intra particle diffusion *** to correlation factor R2, the Pseudo second order model was fitted well with experimental data. The intra particle diffusion model revealed that adsorption in dense membranes was not solely consisting of intra particle diffusion.
