Superconductor -Insulator Transition in Quasi-One-Dimensional Nanowires
… MoGe nanowires fabricated by a molecular templating technique. A well-defined superconductor-insulator transition (SIT) is observed in homogeneous wires with lengths less than ∼200 nm. The total normal state resistance of the wire is found to be the control parameter for this transition …

Conducting polymer actuator enhancement through microstructuring
… can improve strain rates. A unique surface templating technique using breath figures has been developed for poly (3-hexylthiophene). Spherical holes form on the surface of polymer films during the drop casting process if moist air was blown over the top of the film. This technique has been …

Development of Cartilage-Derived Matrix Scaffolds via Crosslinking, Decellularization, and Ice-Templating
… This dissertation utilized collagen crosslinking techniques as well as ice-templating in order to enhance the mechanical properties of CDM scaffolds and prevent cell-mediated contraction. Furthermore, the decellularization of CDM was investigated in order to remove possible sources of …

Development of Stochastic and Anisotropic Multiscale Ceramics Using High Aspect Ratio Sacrificial Fillers
… anisotropic structures via a directional ice-templating technique and hard-templating using the sacrificial filler method. Cellulose nanocrystals (CNCs) aerogels have been created via a ceramic suspension of 100g/mL of CNC powder and deionized water. Samples were then frozen, in cylindrical …

Microwave Response in Superconducting Nanowires
… fabricate superconducting wires using molecular templating technique to study their transport properties when exposed to microwave radiation (MW), at cryogenic temperatures. Our wires have a diameter on the order of the zero temperature coherence length, which makes them quasi-one-dimensional at …

Novel carbon materials with hierarchical porosity : templating strategies and advanced characterization
… using mesophase pitch as carbon precursor, two templating strategies were developed using the nanocasting approach. The synthesized (monolithic) materials combined for the first time the advantages of a hierarchical interconnected pore system in the macro- and mesorange with the advantages of …

Protein containing porous polymers for biocatalytic applications
… carbon dioxide high internal phase emulsion templating technique. The effects of enzyme loading, carbon dioxide pressure and monomer to crosslinker ratio were examined. The corresponding enzyme activity of all the emulsion templated materials was shown to be higher than for the unsupported …

Recapitulating mammary gland development and breast cancer cell migration in vitro using 3D engineered scaffolds
… anisotropic collagen phenotype in vitro, an ice-templating technique was used to modify the structure of the collagen scaffolds producing both non-directional (isotropic) and anisotropic internal architectures. Tumour cells from various breast cancer cell lines were seeded into both isotropic and …

Template-Controlled Synthesis of Magnetic/Semiconducting Nanoparticles within Amphiphilic Core-Shell Cylindrical Polymer Brushes
… chains were synthesized via the “grafting from” technique using a combination of anionic polymerization (for the synthesis of the backbone) and atom transfer radical polymerization (ATRP, for the synthesis of the side chains). The formation of well-defined brushes was confirmed by 1H-NMR and GPC. …

Architectural control of ice-templated collagen scaffolds for cardiac regeneration
… success in other clinical applications. The ice templating technique utilizes phase separation dynamics during solidification and subsequent sublimation of ice to produce scaffolds with interconnected porosity. Although composition has been found to be key to determining cellular response, both …

Monitoring Tissue Function Dynamics in vitro with Bioelectronics: Towards Understanding Barrett’s Oesophagus Pathogenesis
… material in native tissue. Using an ice-templating technique, the conjugated polymer can be fabricated so as to take the form of a macroporous scaffold, which can then be used as a cell-culture substrate, which enforces the three-dimensional architecture of native tissue. This scaffold …
