TL;DR: In vivo analysis in a subcutaneous Wistar rat model at 1, 4 and 12 weeks showed superior implant integration and adipogenesis in the MCS-based composites, with allogenic ASCs promoting cell infiltration, angiogenesis and ultimately, fat formation.

16 Aug 2012TL;DR: In this paper, a light-emitting device with a substrate including a substrate second upper surface provided between a substrate bottom surface and a substrate first upper surface in a height direction is presented.
Abstract: A light-emitting device includes a substrate including a substrate second upper surface provided between a substrate bottom surface and a substrate first upper surface in a height direction. A light-emitting element to emit ultraviolet light is provided on the substrate first upper surface. A protective element includes a protective element upper surface provided between the substrate first upper surface and the substrate second upper surface in the height direction. A frame is bonded to the substrate first upper surface via adhesive members to surround the light-emitting element. The frame includes a frame lower surface opposite to the substrate first upper surface and the substrate second upper surface in the height direction to provide a gap between the substrate first upper surface and the frame lower surface. A space in which the light-emitting element is provided communicates with an outside of the light-emitting device via the gap.

TL;DR: In this paper, SU-8 microstructures have been fabricated and released on the surface of swarming Serratia marcescens, and the flagella propel the structures along the swarm surface.
Abstract: Flagellated bacteria have been employed as microactuators in low Reynolds number fluidic environments. SU-8 microstructures have been fabricated and released on the surface of swarming Serratia marcescens, and the flagella propel the structures along the swarm surface. Phototactic control of these structures is demonstrated by exposing the localized regions of the swarm to ultraviolet light. The authors additionally discuss the control of microstructures in an open channel powered by bacteria which have been docked through a blotting technique. A tracking algorithm has been developed to analyze swarming patterns of the bacteria as well as the kinematics of the microstructures.

TL;DR: In this paper, the effect of ionic radius and work function of metal ions on photocatalytic activity of mesoporous nanocrystalline TiO2 for degradation of acetophenone and nitrobenzene in aqueous medium under ultraviolet light irradiation was investigated.
Abstract: Mesoporous nanocrystalline TiO2 was prepared by hydrolysis of titanium isopropoxide, and the band gap of the TiO2 was modified with transition metal ions Ag, Co, Cu, Fe, and Ni having different work functions by the wet impregnation method. X-ray diffraction (XRD), X-ray photoelectron spectrophotometer, diffuse reflectance spectrophotometer (DRS), scanning electron microscope (SEM), and BET techniques were used for the characterization of the catalysts. By using the DRS technique, the highest red shift of 11 nm and lowest of 1.5 nm were observed for Ni and Fe ion impregnated catalysts, respectively. The investigations were carried out to demonstrate the effect of ionic radius and work function of metal ions on photocatalytic activity of mesoporous nanocrystalline TiO2 for degradation of acetophenone and nitrobenzene in aqueous medium under ultraviolet light irradiation.
