ABSTRACT While remote observations of the linear polarization five low-albedo near-Earth asteroids are available at large phase angles, space missions have collected materials from surface two them and one is already back to Earth. The structure regolith on may be different that encountered larger objects, because their low gravity thermal stress cycling. Dust particles crushed meteorites (i.e....

Concrete has good fire resistance. However, once exposed to rapidly increasing temperatures, concrete may suffer from thermal stress-induced spalling or pore pressure-induced spalling. Compared with normal-weight (NWC), lightweight aggregate (LWAC) a low conductivity and is more prone cause higher temperature gradient under the action of high temperatures. This poses hidden concern safety gener...

In this paper, the solar absorption level of PEDOT:PSS/Ge organic and inorganic hybrid cells (HSCs) with different parameters cruciform microstructure (CM) is studied, using finite-difference time domain (FDTD) method. The light in HSCs CM above 90% range 300 nm to 1300 nm. Under AM1.5 spectrum, average absorptivity energy also at a very high level. At same time, we use DEVICE software calculat...

Inspired by the working principle of naturally-existing photosynthetic and respiratory electron transport chains (ETCs) in phototrophic organisms living cells, we have constructed artificial ETCs to promote kinetics transfer thus achieving efficient conversion haze pollutants electricity light- or (photo-thermal) heat-driven liquid flow fuel cells (LFFCs). Ferricyanide (K3[Fe(CN)6]) VO2+/VO2+ w...

Thermoelectric generators (TEGs) offer a versatile solution to convert low-grade heat into useful electrical power. While reducing the length of active thermoelectric legs provides an efficient strategy increase maximum output power density pmax, both high contact resistances and thermomechanical stresses are two central issues that have so far prevented strong reduction in volume materials int...

Deep-water canopy-forming algae Gongolaria montagnei var. compressa and Ericaria zosteroides (Fucales: Ochrophyta) co-exist in mixed populations, the first taxa dominating at upper limit of distribution (20 m) second lower (40 m). This depth pattern is consistent with photosynthetic performances both taxa, E. showing higher efficiency (α) light saturation (Ik) compensation (Ic) than G. compress...

UNLABELLED BACKGROUND Controversies surrounding the efficacy of surgical sealants against alveolar air leaks (AAL) in lung surgery abound in the literature. We sought to test the sealing efficacy of a novel synthetic sealant, TissuePatch™ in an in vitro lung model. METHODS The lower lobe of freshly excised swine lung (n = 10) was intubated and ventilated. A superficial parenchymal defect (...
