The synthesis of metal-organic framework (MOF) thin films has garnered significant attention during the past decade. By better understanding the parameters governing the nucleation and growth of such thin films, their properties can be rationally tuned, empowering their application as (reactive) membranes. Here, a combined AFM-vibrational spectroscopy research strategy is employed to detail the...

Cell lytic enzymes represent an alternative to chemical decontamination or use of antibiotics to kill pathogenic bacteria, such as listeria. A number of phage cell lytic enzymes against listeria have been isolated and possess listericidal activity; however, there has been no attempt to incorporate these enzymes onto surfaces. We report three facile routes for the surface incorporation of the li...

Hybrid thin film solar cell based on all-inorganic nanoparticles is a new member in the family of photovoltaic devices. In this work, a novel and performance-efficient inorganic hybrid nanostructure with continuous charge transportation and collection channels is demonstrated by introducing CdTe nanotetropods (NTs) and CdSe quantum dots (QDs). Hybrid morphology is characterized, demonstrating a...

We report chemical-vapor-deposition (CVD) synthesis of high-density lead sulfide (PbS) nanowire arrays and nano pine trees directly on Ti thin films, and the fabrication of photovoltaic devices based upon the PbS nanowires. The as-grown nanowire arrays are largely vertically aligned to the substrates and are uniformly distributed over a relatively large area. Field effect transistors incorporat...

Thin film of zinc oxide was prepared by spin coating on pyrex glass using zinc acetate dehydrate, 2methoxyethanol and monoethanolamine (MEA) as a precursor, solvent and stabilizer respectively. Also, Aluminium-doped thin film of ZnO was prepared by using AlCl3. Deposited thin films were investigated for structural and optical properties using X-ray diffraction (XRD) and UV–VIS-NIR spectrophotom...

A thin-film balance employing either a Sheludko capillary or a Mysels-inspired porous-medium film holder provides a direct measurement of disjoining-pressure isotherms in free, liquid thin films. However, each film holder suffers its own distinct disadvantages spanning non-uniform and slow liquid exchange, a limited range of measurable disjoining pressures, an inability for reuse, and a require...

A highly-efficient, flexible piezoelectric PZT thin film nanogenerator is demonstrated using a laser lift-off (LLO) process. The PZT thin film nanogenerator harvests the highest output performance of ∼200 V and ∼150 μA·cm(-2) from regular bending motions. Furthermore, power sources generated from a PZT thin film nanogenerator, driven by slight human finger bending motions, successfully operate ...

A thin film process using ECR-ion beam sputtering with ultra pure (99.999999%) copper target was investigated for improving transportation properties in the film. The electric resistivity of the thin film was 40% lower than that of using a commercial-grade purity target. And the optical qualities evaluated by the transmission and reflection spectrum measurements were also indicate slower relaxa...

OF THE DISSERTATION Modeling and Control of Thin Film Surface Morphology: Application to Thin Film Solar Cells

We proposed optical gas sensors based on PLCs integrated with SnO2 thin films. SnO2 thin film was placed on the core layer appeared by removing the upper cladding layer of PLC. The propagation loss is analyzed using 2-D finite-difference time-domain method as a function of refractive index change of SnO2 thin film. The propagation loss of 0.18 dB was observed when the change of refractive index...
