Fluidized bed coupled rotary reactor for nanoparticles coating via atomic layer deposition

引用

Review of Scientific Instruments 2015年第7期86卷 075101页

作者： Duan, Chen-Long Liu, Xiao Shan, Bin Chen, Rong State Key Laboratory of Digital Manufacturing Equipment and Technology School of Mechanical Science and Engineering Huazhong University of Science and Technology 1037 Luoyu Road Wuhan Hubei430074 China State Key Laboratory of Material Processing and Die and Mould Technology School of Materials Science and Engineering Huazhong University of Science and Technology 1037 Luoyu Road Wuhan Hubei430074 China

A fluidized bed coupled rotary reactor has been designed for coating on nanoparticles (NPs) via atomic layer deposition. It consists of five major parts: reaction chamber, dosing and fluidizing section, pumping section, rotary manipulator components, as well as a double-layer cartridge for the storage of particles. In the deposition procedure, continuous fluidization of particles enlarges and homogenizes the void fraction in the particle bed, while rotation enhances the gas-solid interactions to stabilize fluidization. The particle cartridge presented here enables both the fluidization and rotation acting on the particle bed, demonstrated by the analysis of pressure drop. Moreover, enlarged interstitials and intense gas-solid contact under sufficient fluidizing velocity and proper rotation speed facilitate the precursor delivery throughout the particle bed and consequently provide a fast coating process. The cartridge can ensure precursors flowing through the particle bed exclusively to achieve high utilization without static exposure operation. By optimizing superficial gas velocities and rotation speeds, minimum pulse time for complete coating has been shortened in experiment, and in situ mass spectrometry showed the precursor usage can reach 90%. Inductively coupled plasma-optical emission spectroscopy results suggested a saturated growth of nanoscale Al2O3 films on spherical SiO2 NPs. Finally, the uniformity and composition of the shells were characterized by high angle annular dark field-transmission electron microscopy and energy dispersive X-ray spectroscopy. © 2015 AIP Publishing LLC.

The use of complex systems with switching behavior and control design such as multitask walking and flying robots which need different Equation of Motion (EOM) for their states has become more popular recently. Having a reliable, exact and easy to drive dynamic model is important for their analysis, design, path planning and control. While the Newton and Lagrange approaches are being used widely to derive robot dynamics, they are not fully optimized for numerical modelling of systems with switching behaviors. TMT method which is a linear vector form for Lagrange EOM has recently been used, but not generally intruded and investigated, to simplify the EOM derivation and improve the numerical simulation efficiency of robotic system models. Here a systematic approach to derive EOM of different rigid body robot systems with impact using TMT method is presented. An automatic algorithm and a code based on that is developed in Matlab language to derive different systems’ EOM. The algorithm needs simple geometric inputs for joints, actuator inputs, external loadings and constraints; and can be used for modelling both serial and parallel mechanism with external collision. The application of this approach and algorithm inputs is shown for three sample systems: a biped walker with upper body, a flapping flyer and a Clemens joint.

Influence of zirconia shot peening treatment on high-cycle fatigue properties of Ti-6Al-4V

Rotating bending loading and axial loading fatigue tests were conducted to investigate the effect of zirconia shot peening on fatigue properties of Ti-6Al-4V ELI alloy. Specimen was treated in three different shot peening conditions. As a result of the rotating bending fatigue tests, the fatigue lives of shot peened specimen were longer life than non-peened specimen. Fish eyes were observed in the fracture surface of the most shot peened specimen. And there was the facet of α-Ti or the fine granular region near the crack initiation site of the fish eye. And then, fracture morphology of shot peened specimens is different by peening conditions. From the result of axial loading fatigue tests, it becomes obvious that the facet of α-Ti was formed by action of tensile stress over 500MPa without compressive stress and that the fine granular region was formed by action of compressive stress. These results suggested that low level tensile residual stress existed at subsurface near the surface of the SP treated specimen, and the residual stress distribution decided on internal crack origin type between the facet of α-Ti or the fine granular region. © 2016 The Society of materials science, Japan.

Osteogenesis of MC3T3 Preosteoblasts on 3D Bioactive Peptide Modified Nano-Macroporous Bioactive Glass Scaffolds

引用

Journal of Biomaterials and Nanobiotechnology 2015年第3期6卷 146-159页

作者： Colin Przybylowski Mohamed Ammar Courtney LeBlon Sabrina S.

Biointerface design that targets osteogenesis is a growing area of research with significant implications in biomedicine. materials known to either support or stimulate osteogenesis are composed of a biomimetic ceramic material, such as bioactive glass. Bioactive glass is osteoproductive, and the potential for osteoproductivity can be enhanced by the addition of proteins or other additives designed to alter functionality. In addition, soluble growth factors are often added to osteogenic culture on bioactive glasses, further intensifying the effects of the material. In this paper, synthetic peptide combinations, covalently bound to a three-dimensional bioactive glass network, are used to mimic the effects of the whole fibronectin and bone morphogenetic proteins (BMP) 2 and 9. Peptide-silanes possessing critical binding sequences from each of these proteins are synthesized and used to decorate the surface of three-dimensional (3D) nano-macroporous bioactive glass. MC3T3 preosteoblast cells are then assessed for differentiation on the materials in the absence of soluble differentiation cues. MC3T3 preosteoblasts undergo enhanced differentiation on the peptide-silane samples over the standard nano-macroporous bioactive glass, and the differentiation capacity of the cells exposes only to peptide-silane surfaces approaches that of cells grown in chemical differentiation induction media.

WPA Mk II Project started in 2011 in response to the ESA spare procurement philosophy for ISS life extension up to 2020 (and possibly beyond 2020). The project involves TASI as responsible for the design, development, manufacturing, integration and testing of this new water pump package for the ISS Columbus module. This pump package is responsible for the circulation of water inside Columbus pipelines to ensure proper thermal control not only for the Payloads (PL's), but also for the cabin where astronauts work and live, and consequently represents the core of the Thermal Control System in Columbus. WPA Mk II is characterized by several innovations in comparison with the current WPA Mk I installed in Columbus, like new functionalities (on board SW uploading capability), or new technologies (ultrasonic flow meter), up to a high level modular design (characterized by several ORUs, on Orbit Removable Units, conceived to optimize R&R operations and associated time and costs). A successful Critical Design Review has been achieved in July 2014, in Turin, with the support of the European Space Agency and Airbus. Now TASI is approaching MAIT phase: in the 2015 there will be the integration and testing of the various ORUs while the 2016 will be characterized by the integration and testing of the two pump packages WPA Mk II to demonstrate system compliance to the launchers and Columbus environmental and functional requirements. The present article provides an overview of the Project, the main features, the mission scenarios, and a general overview about the associated Qualification plan at Component, ORUs and Assy level.

Direct evidence is provided for the transition from surface conduction (SC) to electro-osmotic flow (EOF) above a critical channel depth (d) of a nanofluidic device. The dependence of the overlimiting conductance (OLC) on d is consistent with theoretical predictions, scaling as d−1 for SC and d4/5 for EOF with a minimum around d=8 μm. The propagation of transient deionization shocks is also visualized, revealing complex patterns of EOF vortices and unstable convection with increasing d. This unified picture of surface-driven OLC can guide further advances in electrokinetic theory, as well as engineering applications of ion concentration polarization in microfluidics and porous media.

Gongneng Cailiao/Journal of Functional materials 2015年第17期46卷 17049-17052and17057页

Femtosecond laser ablation of the surface on GaAs solar cell has been investigated. The research results indicated that femtosecond laser irradiation start to cause damage to the GaAs solar cell surface at the pulse fluence of 0.27 J/cm2and the injury degree increase with the increase of laser fluence or the decrease of scanning speed. The ablated surface were characterized by optical microscopy, found that the ablation area expanding with increasing laser fluences, which was due to the Gauss distribution of femtosecond laser energy. The abaltion threshold of the TiO2/SiO2films of GaAs solar cell surface was obtained from the linear fit of the dependence of the square diameter of the ablated area with the natural logarithm of the laser pulse energy, the resulting threshold of the laser fluence was about 0.35 J/cm2, which was greater than the test result 0.27 J/cm2. The certain numerical difference might be due to the simplified theoretical calculation of laser spot pattern and the uncertainty factors of material. ©, 2015, Journal of Functional materials.
