To improve membrane materials in water filtration, which currently display broad pore size distribution, hydrophobic chemistry, and fouling behavior, a novel design of chemistry and morphology of membranes is employed. First, through fundamental studies of morphological formation both in bulk by lattice-Boltzmann (LB) simulation methods and at the surface by observation of electron micrographs, it is illustrated that phase separation via spinodal decomposition is responsible for pore development. This understanding suggests the possibility to tailor a uniform and interconnected porous membrane by using the spinodal structure. Considering that the control of spinodal porous structure on a nanoscale can be challenging, an alternative approach to achieve a similar interconnected morphology by utilizing the self-assembled structure of a graft copolymer is presented. This graft copolymer permits not only the design of morphology through its architecture, but also the design of chemistrythrough its chemical components. Here, a comb-type structure of a copolymer is applied; this structure contains a hydrophobic poly(vinylidene fluoride) (PVDF) backbone for structural integrity and hydrophilic poly(ethylene oxide) (PEO) side chains for preferential water transport. A membrane with the microphase-separated structure of this copolymer at the surface is then utilized to clean oily water wastes where the membrane rejects more than 99.9% of the oil without fouling. This membrane can also perform molecular sieving...

Consumer demand is hard to predict in any industry, let alone the automotive industry. Vehicle manufacturers try to produce according to what their customers want, but if these wants change, the company is faced with lots of unsold cars and a huge changeover cost. In order to help fight the problems of demand variability, automotive manufacturers have begun the move towards plant flexibility. This includes designing vehicles comprised of similar subassemblies and the development of flexible tooling. The hope is that multiple vehicles can be produced on the same line so if demand starts to fluctuate, they can change the production levels of their styles with minimal lead time. There are a number of different approaches to flexible tooling. One approach using programmable robotic repositionable tools (PRRT) is particularly promising because it can handle a large number of styles and requires low style specific reinvestment costs. This thesis examines the PRRT technology as well as other forms of flexible tooling to understand the conditions under which these approaches make the most economic sense.; (cont.) For this project an algorithm was developed to choose assembly tools based on subassembly characteristics, production levels, style counts...

One fundamental challenge in designing organic light-emitting diodes is luminescence quenching near an electrode. In this work, we investigate the underlying mechanism behind luminescence quenching by measuring the reduction in Alq3 photoluminescence due to SnO02. Using an analytical model and a Monte Carlo simulation for exciton dynamics in amorphous organic solids, we find that the exciton diffusion length in bulk Alq3 is in the range of 70--80 A. We also find that for SnO2 films deposited without oxygen in the sputtering ambient, resonant energy transfer from Alq3 to SnO2 is the dominant quenching mechanism. By varying the oxygen content in the Ar/C)2 sputtering gas mixture, we find that the energy transfer distance decreases from 10--25 A for 0% 02 to less than 2 A for 10% 02. Our experimental results suggest that because excess oxygen reduces oxygen vacancies and defect electronic states in SnO2, it leads to a smaller spectral overlap between the emission of Alq3 and the absorption of SnO2, thereby shortening the energy transfer distance and reducing the quenching capability of SnO2.; by Jun Mei.; Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Materials Science and Engineering, 2006.; Includes bibliographical references (p. 83-86).

Advances in nanochemistry will drive the development of technologies at the scale of 1 - 100 nm. Principles of biology are used for the self-assembly of structures and devices at this scale. The Ml 13 bacteriophage, a virus employed in phage-display libraries, serves as a scaffold for nanoscale structures. Phage are functionalized with inorganic materials, and controlled placement of phage at the nanoscale may lead to useful devices. Substrates patterned with dip-pen nanolithography (DPN) serve as templates for the deposition of phage. On gold substrates, 16-mercaptohexadecanoic acid (MHA) is deposited to form patterned lines. After surface passivation and activation chemistry, phage are deposited and adhere to the patterned substrate. Images from atomic force microscopy support that phage are covalently coupled to MHA lines and that cobalt precipitates on patterned phage.; by David S. Gray.; Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Materials Science and Engineering, 2006.; Includes bibliographical references (leaves 25-26).

The immersion precipitation process makes most commercial polymeric membranes, which enjoy widespread use in water filtration and purification. In this work, a ternary Cahn-Hilliard formulation incorporating a Flory-Huggins homogeneous free energy function is used to model both initial diffusion and the liquid-liquid demixing stage of the immersion precipitation process, which determines much of the final morphology of membranes. Simulations start with a simple non-solvent/solvent/polymer ternary system with periodic boundary conditions and uniform initial conditions with small random fluctuations in 2D. Results in 2D demonstrate the effects of mobilities (Mij) and gradient penalty coefficients (Kij) on phase separation behavior. A two-layer polymer-solvent/non-solvent initial condition is then used to simulate actual membrane fabrication conditions. 2D simulation results demonstrate an asymmetric structure of membrane morphology, which strongly agrees with the experimental observation. A mass transfer boundary condition is developed to model the interaction between the polymer solution and the coagulation bath more efficiently. Simulation results show an asymmetric membrane with connected top layer.; (cont.) Then a wide range of initial compositions are used in both the polymer solution and the coagulation bath...

There is a significant need for improved synthetic materials as orthopedic implants to replace human bone lost and damaged due to disease or injury. Certain ceramics, such as hydroxyapatite (HA), have the special property of being bioactive, meaning that an interfacial bond between the implant and the surrounding tissue forms, leading to good fixation. Bioactive ceramics are being investigated in a wide variety of forms for use in different bone implant applications. Three model synthetic HA based bioceramic systems were examined; phase pure, dense, polycrystalline HA; phase pure, dense, polycrystalline HA with 0.8 wt% silicon substituted into the lattice (SiHA); and phase pure, dense, nanostructured HA (nanoHA) with grain sizes less than 100 nm. SiHA has shown markedly enhanced bioactivity over non-substituted HA yet they have similar micro- and meso-scale properties and nanoHA has shown increased bioactivity over traditionally structured HA although they are chemically identical. The form of a biomaterial, the nanoscale surface chemical properties (e.g. surface functional groups, charge distribution, Hamaker constant), and morphological structure (e.g. grain size, shape, distribution, roughness) will govern its interaction with the biological environment.; (cont.) The three main processes thought to occur upon implantation of a bioactive material are the adsorption of ions and biomolecules...

Conventional methods used to fabricate co-fired tungsten/alumina composites usually rely on high temperature processing (>1500C). As it would be beneficial or even necessary for some applications to produce such composites at relatively low firing temperatures, low-temperature processing techniques and the attendant knowledge of processing-property relationships need to be developed. In this thesis, a set of experiments and simulations are performed to obtain a better understanding of sintering and joining of the tungsten/alumina system processed at temperatures near or below 12000C. The technique of activated sintering for tungsten is investigated, whereby a minimal content of additives enables low firing temperatures through a change in the sintering mechanism for tungsten. Tungsten compacts produced by this method are found to sinter only to the "initial stage" and are characterized by high residual porosity level. Hardness and fracture toughness of such partially-sintered materials are examined experimentally and analytically, and dependence of mechanical properties on the relative particle neck size is observed. Various studies are carried out to examine both fundamental and practical aspects of joining co-fired tungsten/alumina.; (cont.) First...

Nanoparticles comprise a versatile class of nanomaterials that consist of particles that have a characteristic length scale less than 100nm. They are on a similar length scale as many biological elements, so it is fitting that they are being used increasingly in biological systems for a variety of applications. Interesting properties of water-soluble metal nanoparticles that could lead to novel biological applications include bio-catalytic, sensing, and light scattering capabilities. We will present here the characterization of novel highly water-soluble gold nanoparticles that can be used as model systems to study the fundamental mechanisms of cellular uptake and intracellular trafficking.; by Suelin Chen.; Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Materials Science and Engineering, 2007.; Includes bibliographical references (leaves 41-43).

The biophysical properties of the human red blood cell (RBC) permit large deformations required for passage through narrow capillaries and spleen sinusoids. Several pathologic conditions alter RBC deformability that can result in abnormal circulation behavior. In the present work, altered RBC deformability caused by invading Plasmodium falciparum parasites, which are responsible for the disease malaria, is evaluated. P. falciparum parasitized RBCs (pRBCs) display decreased deformability and novel cytoadherence properties, and sequester in the microcirculation. Parasite-exported proteins that interact with the pRBC membrane are identified as the cause for these alterations. It is postulated that sequestration of pRBCs is responsible for severe cases malaria. Previous studies of pRBC deformability could not characterize deformability over all parasite intra-erythrocytic developmental stages due to experimental limitations. In the present work, a technique based on optical tweezers is developed to permit testing of pRBC deformability over all intra-erythrocytic stages. Optical tweezers can measure the force versus displacement response of a single RBC in uniaxial tension. The membrane shear modulus, which is a major factor in determining overall RBC deformability...

A fluxless low temperature transient liquid phase (LTTLP) bonding process was studied as a method of producing Cu/Cu joints below 125°C and 75°C using interlayer alloys from the In-Sn and In-Sn-Bi systems. Using thermodynamic models, three different compositions (wt. %) of base alloys were chosen to accomplish this task: 50In-43.6Sn-6.4Bi (Tm = 110°C) and eutectic 50.9In-49.1Sn (Tm = 120°C) alloys were used for bonding at 125°C and a eutectic 48.3In-15.6Sn-36.1Bi (Tm = 60°C) alloy was used for bonding at 75°C. In addition, novel approaches to TLP bonding, including the addition of base material to the interlayer alloy and application of an electroless Ni diffusion barrier layer, were employed in an attempt to optimize this joining method. The LTTLP processes were assessed based on their abilities to produce joints with minimal thickness, high reflow temperatures, and good mechanical properties at room/elevated temperatures. It was found that interlayer alloys containing higher Bi contents produced the thinnest joints, with the 48.3In-15.6Sn-36.1Bi alloy producing joints on the order of 10 gm. Increases in nominal Cu composition of the interlayer alloy tended to form larger joints. Application of the Ni layer was observed to decrease the growth rate of the eutectic In-Sn joints made with 5 wt % Cu additions. Shear tests were performed on the joints at room (25°C) and operating (service) temperatures (100°C). Most of the TLP joints had room temperature shear strengths around 13...

Cancer immunotherapy attempts to stimulate the immune system to reject and destroy tumor cells. Despite the amount of ongoing intensive research to prevent cancer, tumor cells continue to evade immune responses. Currently, dendritic cell vaccines are in development, in which autologous antigen-loaded dendritic cells are injected back into the patient in order to generate an appropriate immune response. Improving upon this idea, members of the Irvine laboratory are in development of an injectable dendritic cell based formulation that gels in situ around the tumor site. In this way, immune cells (most notably T cells) can be recruited and become activated against specific tumor antigens, and (hopefully) kill tumor cells. Recent studies have shown the potential benefit of incorporation of cytokine interleukin-15 complexed with its soluble receptor interleukin-5R[alpha], which is discussed. Economic considerations are also discussed, including topics such as intellectual property, barriers to entry, initial markets and market drivers, and entry into the current supply chain considerations. A business strategy is outlined and evaluated.; by Andrew Song.; Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Materials Science and Engineering...

There has been much hype in the research and development of continuous glucose monitoring technologies, driven by the enormous and rapidly expanding glucose monitoring market and the large and growing base of diabetes patients. Continuous glucose monitoring has shown significant benefits over traditional intermittent blood glucose testing in reducing the risks of developing long-term complications associated with diabetes, by maintaining blood glucose concentrations to near-normoglycemic levels and reducing glycemic variability. In this thesis, commercially available continuous glucose monitoring systems as well as those still in development are evaluated. SWOT analysis shows that continuous glucose monitoring has a promising future, but there remain a number of challenges to be overcome, such as accuracy, sensor span, data handling, cost and reimbursement issues. It is concluded that continuous glucose monitoring will be the roadmap for future diabetes management. Ongoing technological advances in continuous glucose monitoring systems will hopefully close the loop for a fully automated artificial pancreas and develop a cure for Type I diabetes.; by Guang Li.; Thesis (M.

In recent years, the epitaxial Cu/Ni/Cu thin film system has been extensively studied, due to its wide range of perpendicular magnetization. It has proved to be a model system to explore the interactions of strain, surface energies and magnetic properties. For that reason, is also an ideal system to explore the effects of patterning. It is expected that the miniaturization of patterned magnetic devices will be accompanied by a transition from polycrystalline to epitaxial films. This transition will require a detailed theoretical understanding of the interaction of strain and magnetic properties in patterned epitaxial magnetic thin films. The Cu/Ni/Cu film system is used in this work to explore a triaxial model for an orthorhombic symmetry of strain. By patterning the Cu/Ni into nanolines and measuring the resulting magnetic anisotropy, the validity of the model has been tested. It has been shown that upon patterning certain thicknesses of nickel into nanolines, the easy axis of magnetization shifts from out of the film plane to in-plane, transverse to the line direction, an observation at odds with the direction of magnetization predicted by shape considerations alone. This transition is explained by the dominant magnetoelastic energy for the Cu/Ni/Cu nanoline system.; (cont.) The resulting anisotropy values are consistent with strain relief values predicted by finite element modeling. In addition...

(cont.) Generally, a boundary is nonplanar in the neighborhood of an attached particle--even when anisotropic interfacial free energies do not produce faceting-and maintains a icKy = 0 while the boundary particles maintain a nonzero ,Ky. This is consistent with independent observations of Pb-rich particles at grain boundaries in dilute Pb-AI alloys. Predicted particle/boundary morphologies give a trade-off between boundary and particle interface-a particle replaces some boundary but also produces boundary area through local distortions. This result has several implications. The transition to perfect wetting requires a larger boundary energy density. The steady-state heterogeneous nucleation rate is increased when facets appear on the nucleus, but the increase is diminished if the boundary distorts. A corollary result presented in this thesis, that particles can induce rotations or ser- ration through torques, has implications in microstructural stability and illustrates avenues for future research.; Many material properties depend on grain and phase boundary morphology. Equilibrium boundary and particle morphologies are determined by their interactions through interfacial free energy. Currently, the determination of boundary and particle morphology is...

Ni-n-Ga based ferromagnetic shape-memory alloys (FSMAs) have shown great promise as an active material that yields a large output strain over a range of actuation frequencies. The maximum strain has been reported to be 6% in the tetragonal martensitic phase and up to 10% in the orthorhombic phase. There has been a large body of work exploring the engineering properties of these alloys but less extensive work in the understanding of the underlying structure and its connection to the material properties. This is particularly true for the off-stoichiometry compositions that are of most practical interest. The crystal structure of Ni-Mn-Ga ferromagnetic shape-memory alloys is extremely sensitive to composition. Several martensitic structures including tetragonal (5-layer), orthorhombic (7-layer) and non-modulated tetragonal have been identified. A systematic exploration of the composition-structure relationship has been performed using x-ray diffraction on samples taken from several single crystals with different compositions. A room temperature phase diagram has been constructed delineating the fields where the tetragonal and orthorhombic martensites are found.; (cont.) Temperature-dependent magnetic and x-ray measurements have revealed markedly different transformation behavior in the tetragonal and orthorhombic materials. The orthorhombic material shows a much larger difference between the martensite start and finish temperatures as compared to tetragonal martensite. The observed difference in transformation behavior has been shown not to be related to composition inhomogeneity or the presence of intermediate martensitic phases. A thermodynamic model is proposed to explain the differences in the transition behavior by including strain energy effects in the two martensite phases that may arise during the transformation. Single-crystal and powder neutron diffraction have been employed to study for the first time the chemical ordering in the austenite and martensite phases in off- stoichiometric alloy compositions. A comparison of compositions with close to 50 at% 3Ni and those further from stoichiometry revealed the need for a more complex model for the site occupancy in alloys with a significant excess or deficiency of Ni.; (cont.) The microstructure of several different Ni-Mn-Ga alloys was analyzed using transmission electron microscopy providing new microstructural data that has not been shown elsewhere. The superstructures of the different compositions has been confirmed...

In this thesis, we discuss the motivation for integrated magneto-optical isolators and explain why the orthoferrite is such an attractive materials class for this purpose. We then derive from first physical principles the dependence of Faraday rotation, absorption, and certain figures of merit on the material's dielectric tensor elements. Next, we use pulsed laser deposition to grow thin films of BiFeO3 on MgO (001) and SrTiO3 (001) substrates. After optimizing growth conditions to obtain high quality films, we characterize the films' crystal structure with two-dimensional x-ray diffraction. We then examine the magnetic, optical, and magneto-optical properties of these films. We find that the highly textured films grown on SrTiO3 are monoclinic with an out-of-plane c-axis aligned with the (001) direction of the substrate and approximate pseudocubic lattice parameters of a = b = 4.04 A, c = 3.95 A, and 90° - [beta] = -0.88°. These films are weakly magnetic, with a magnetization of 1.2 emu/cm3 at an applied field of 10 kOe; highly absorptive, with an average absorption coefficient of 910 cm-1; and possess a low specific Faraday rotation of 320/cm at 1.8 kOe of applied field. As expected, we find that the magneto-optical figure of merit is negligible for this material due to its high absorption...
