Abstract:
This paper describes a novel method for coating hydroxyapatite (HA, Ca10(PO4)6(OH)2) nano-particles onto poly(DL-lactic-co-glycolic acid) (PLGA) scaffold. Paraffin micro-spheres were used as porogens to create porous scaffolds and as vehicles to transfer HA into PLGA scaffold. HA nano-particles / 50% ethanol suspension was mixed with paraffin micro-spheres. The paraffin micro-spheres / HA suspension were pressed together to form a paraffin scaffold. After it was dried, the HA was coated on the surface of the paraffin spheres. Then, PLGA solution was cast into the inter space among the paraffin micro-spheres and then the solvent was evaporated. Afterwards, the paraffin micro-spheres were dissolved and removed. PLGA scaffolds with controlled pore size, good interconnectivity and high porosity were obtained. The HA nano-particles were transferred from the paraffin surface to the surface of the pore wall throughout the PLGA scaffold.

Abstract:
Novel uniform nano/micron-sized ZnO spheres assembled from the aggregation of nano-particles have been synthesized by hydrothermal method. It was observed that ZnO spheres with controllable diameter were obtained when various volume ratios of triethanolamine (TEA) to H2O were used. Increasing the volume ratio of TEA to H2O could result in the formation of loosely packed ZnO spheres. The UV-visible absorption spectra show that the absorption peak red-shifts with the increasing average diameter of the spheres.

Abstract:
The integration of molecular imprinting technique and solid-phase extraction (SPE) implements an effective alternative for sample pre-concentration in the determination and analysis of veterinary drug/pesticide residues. Herein, we reports a preliminary study on the preparation of streptomycin imprinted polymers on the surface of silica micro-spheres (with an average size of 50μm) and nano-spheres (with an average size of 500nm) via sol gel method. A mixed solution of tetrahydrofuran, ethanol and water (volume ratio is 7:1:1) was choose as dispersion agent, 3-aminopropyltriethoxysilane and phenyltriethoxysilane as functional monomers, and tetraethyl orthosilicate as cross-linker, while ammonia solution served as catalyst in the polymerization process. Scanning electron microscopic characterization was employed, suggesting that activating time exerts important influences on the morphology of activated silica micro-spheres, and also resultant molecular imprinted polymers (MIPs). The absorption capacity and selectivity of the obtained two MIPs were also evaluated for streptomycin and its analogue compounds in water samples. The results illustrate that the streptomycin-imprinted silica micro-spheres (MMIP) exhibited both larger absorption capacity and higher selectivity than those of silica nano-spheres (NMIP). The variant analytical performance might result from inadequate polymerization on the surface of silica nano-spheres.

Abstract:
Noble-metal-based nanostructures can exhibit strong localized plasmon resonance at optical frequency, which leads to efficient plasmonic light absorbers. Such an artificially engineered absorber can have potential applications in sensing, cancer diagnosis and therapy, and photovoltaic cells etc. This thesis systematically studies a particular class of plasmonic absorber based on gold nanoparticles deposited on top of a continuous gold substrate. In our case studies, the nanoparticles have sub-wavelength sizes of less than 50 nm; their reflectances are examined over 400-800 nm light wavelength range. With a 3D finite-element method, we identified that the resonance at especially a long-wavelength position originates not from dipole resonance of the particles, but from the inter-particle near-field coupling resonance. The influences of particle size, particle shape, inter-particle distance, particle-substrate spacer, particle lattice, number of particle layers etc on the resonance are studied thoroughly. Experimentally, an absorber based on chemically-synthesized Au@SiO2 core-shell nanoparticles was fabricated. Measurement shows that the absorber has a characteristic absorption band around 800 nm with an absorbance peak of 90%, which agrees surprisingly well with our numerical calculation. The fabrication technique can be easily scaled for devising efficient light absorbers of large areas.

碩士<br>逢甲大學<br>化學工程學所<br>98<br>The applications of nanometer technology is attracted a lot of attention. Nanometer scale hollow spheres can be used in the hydrogen materials and drug delivery, etc. Therefore, nanometer scale hollow spheres prepared by reverse micelle method is going to research in this work (experiment). We divided the water phase into two groups including pure water and ammonia solution are discussed. Then we are trying to find the optimal condition to make the reproduction of nanometer scale hollow spheres which based on the five factors （the quantity of TEOS, ammonia solution concentration, the shake/agitation time, the shake amplitude and the sampling time）. Reverse micelles method goes through with mixing TEOS, hexane and water/ammonia solutions together in various vol % by ultrasonic processor for 2 min. The mixture solution will separate into oil phase and water phase, then we took out the oil phase of mixture solution which is a reverse micells system of water in oil （W/O）. The droplets （namely reverse micelles） will undergo the sol-gel reaction while precipitating after lefting for 1h. The ammonia in the droplets catalyzed the TEOS in the oil phase from solid, i.e. the silica hollow spheres, at the oil-water interface. Took the upper layer of the oil phase and analyzed the particle size distribution and the surface morphology of nanometer scale hollow spheres which examined by DLS, AFM, TEM and FM, respectively.

Abstract:
碩士<br>中原大學<br>土木工程研究所<br>100<br>The main factors that affect the activated carbon derived from three sugars (glucose, sucrose, and xylose) to form hydrothermal carbon spheres were studied by chemical activation with solution of KOH. The experimental operating conditions were as follows: the carbonized temperature 600-800℃ and keeping time 3 h using N2 as protective gas; the activation temperature 600-900℃ and holding time 2-5 h; the 2-5 folds mass ratio of KOH to carbonized material; the 30 min of soaking carbonized material in the solution of KOH. Effects of preparation conditions on the revolution of microstructure and surface chemistry characteristics of activated carbon are characterized with TEM, XRD, nitrogen isotherms, FTIR, and zeta potential, from which not only obtaining the best preparation conditions for producing activated carbon that possessing high surface area and pore volume, but also providing more information for the synthesis parameters on the conversion mechanism of carbon spheres into activated carbon. The adsorption capacities of the basic dye (MG5), the acid dye (AR1), the organic compound (phenol), and two heavy metal ions (Cu2+ and Pb2+) on the activated carbon were measured. Under the optimal conditions, the specific surface area (yield rate and ratio of micropore volume to total pore volume) of activated carbon derived from glucose, sucrose, and xylose reached 1611.7 (11.5 and 41.0 %), 1493.6 (19.2 and 92.4 %), and 1362.5 (10.8 and 83.8 %) m2/g, respectively. For MG5 (AR1, phenol, Cu2+, and Pb2+), the maximum adsorption capacity of activated carbon derived from glucose, sucrose, and xylose may reach 443.9 (345.7, 277.9, 58.1, 81.1), 538.0 (189.3, 267.2, 64.6, 86.6), and 599.4 (371.8, 331.9, 61.3, 91.0) mg/g, respectively. It can be experimentally concluded that the activated carbon from hydrothermal method derived carbon spheres may be an excellent adsorbent for the adsorptive removal contaminations from aqueous solution, although obtained materials do not possess the relatively larger specific surface area.

UV irradiation can cause damage to cells and DNA. Under increasing environmental pressures, creatures need to prevent the damages from UV irradiation. It also affects the growth and reproduction of many organisms and plays an important role in the whole ecosystem. So it is very important to study how creatures to protect themselves from UV damage. The aim of this study was to investigate whether nano-coating on surface of insects could help insects to avoid UV damage. When the insects were exposed to ultraviolet light, the results showed that insects smeared their compound eyes with the surface of nanometer protein spheres, and that achieve the purpose of anti-ultraviolet light.

Abstract:
碩士<br>逢甲大學<br>化學工程學所<br>98<br>The motion of study was using reverse micelles to prepare PMMA (poly methyl methacrylate) hollow sphere. Prepared reverse micelles by using surfactant TOAB (tetra-n-octyl ammonium bromide) and dissolved in toluene. In water phase, we added the initiator and mixed two phase by ultrasonic processer. Then took out the upper layer from oil phase and added the monomer MMA and cross-linker EGDMA (ethylene glycol dimethacrylate). The size of hollow sphere was decided by amplitudes and time. The advantage of this method was the initiator contained in water cell and covered by oil and surfactant. Then we added co-surfactant to assist the stability of reverse micelles. The analysis of the sample include the AFM (atomic force microscopy ), Fluorescence microscopy, submicron particle size analyzer and TEM (Transmission electron microscope ). Consequently, using the particle size analyzer to analysis the size of reverse micelles, the co-surfactant 1-dodecanol was the best system to stable the reverse micelles and the result of polymerization. And after the polymerization,the sizes of cross-linked hollow spheres all were under 10 nm. Using AFM could get the same result with particle size analyzer. Using TEM could know the hollow structures were very obviously, and the each one of the hollow radius was almost the same. So the method of this study was the way to prepare the PMMA/EGDMA cross-linked hollow sphere.

Modern science and technology centred on carbon-based nanomaterials are changing at a fast pace, with the potential to replace or complement current systems. Carbon-based materials that can be produced and characterised at the nanoscale have become a cornerstone in nanotechnology. The morphologies and topographies of these carbon compounds can be quite diverse. As the well-known families of fullerenes and carbon nanotubes demonstrate, they can have hollow or filled frameworks and can assume a variety of forms. In this chapter, the synthesis, types, applications (water purification, bio-medical, gas sensors, and transport materials in plant breeding) and some impacts of nano-carbon materials such as nano-spheres, nano-tubes, nano-fibres, and helices are discussed.

Self assembly has been a developing theme through this monograph. Some structures, by the nature of the processes used in their synthesis form molecules which naturally self assemble. Carbon-based spheres and nano tubes have interesting and important characteristics. Sheets of carbon, graphene, exhibits electrical conductivity and physical property characteristics which make these materials potentially very important technologically. So-called intrinsic conducting polymers have been developed form polyacetylene and are utilized in display applications. Reinforcement of polymer systems can also be achieved by the use of exfoliated clay systems, in which the nano scale of the clay platelets allows order to be created within the polymer matrix. Combining inorganic and organic elements it is possible to create structures with large voids for permeation applications and to influence the growth or inorganic crystals by habit control.

Full text
Abstract:
Crowdsourcing is being researched as a problem-solving technique by issuing open calls for solutions to large crowds of people with the incentive of prizes. This paper tackles the dual objectives of building cluster flight software and educating students using collaborative competition, both in virtual simulation environments and on real hardware in space. The concept is demonstrated using the SPHERES Zero Robotics Program, a robotics programming competition where the robots are nano-satellites called SPHERES onboard the International Space Station (ISS), traditionally used as a Guidance, Navigation and Control testbed in microgravity. Zero Robotics allows students to program SPHERES to play a game through a web-based interface and the most robust projects are evaluated on the ISS hardware, supervised by astronauts. The apparatus to investigate the influence of collaboration was developed by (1) building new web infrastructure where intensive inter-participant collaboration is possible, (2) designing a game that incentivizes collaboration with opponents, to solve a relevant formation flight problem and (3) structuring a tournament such that inter-team collaboration is mandated. The web infrastructure was also built using collaborative competitions, to demonstrate feasibility of building space software end-to-end by crowdsourcing.

Abstract:
Abstract Owing to superior temperature stability in comparison with water-based drilling fluids, oil or synthetic-based drilling fluids are generally preferred for high temperature and high pressure (HTHP) formations. However, the thermal degradation of emulsifiers and polymeric components under HTHP conditions that results in loss of rheological and filtration control, barite sag or even fluid phase separation also occurs. It is a challenge to sustain these properties stable under such harsh condition. Since nanoparticles have potential to provide better thermal stability, improved filtration loss as well as emulsion stability, the aim of this study is to investigate the effect of nano carbon spheres on the properties of oil-based drilling fluids under high temperature conditions. The nano carbon spheres were synthesized with the hydrothermal reaction of glucose. The influence of nano carbon spheres on the rheological, filtration, emulsion stability, settlement stability, as well as lubricity of a typical mineral oil-based drilling fluid with oil to water ratio of 80:20 was investigated before and after thermal aging at 180 and 200°C, respectively. The structure characterization showed that the uniform hard nano carbon spheres exhibited intermediate wettability. Laboratory performance test indicated that, for the oil-based drilling fluid, the addition of nano carbon spheres improved the rheological properties in terms of yield point and the ratio of yield point to plastic viscosity, which is beneficial for transporting of drilling cuttings. After thermal aging at 200 °C, the filtration loss volume was reduced as high as 70%, and desirable filter cake quality was obtained by incorporation of 1.0 wt% spheres, meanwhile the electrical stability was improved both before and after thermal aging. Furthermore, the fluid formulated with the nano carbon spheres generated better barite sag control. The polarizing microscope observation showed that the nano carbon spheres accumulated at the water-oil interface and formed a steric barrier which probably explained the reason of the above enhanced performance. The green synthetic routes and environmental friendly characteristics of the nano carbon spheres, in combination with the excellent properties suggested that the nano carbon spheres hold potential as multi-functional additives for formulating oil-based drilling fluids for HTHP drilling operations.
