Microstructural Characteristics and the Charge-Discharge Characteristics of Sn-Cu Thin Film Materials

Charge/discharge and Electrochemical Characteristics of Secondary Lithium/pyrite Battery

Iron disulfide (FeS2) is attractive as a positive electrode material in lithium batteries because of its low material cost, environmental non-toxicity, and high specific energy density. Furthermore, natural pyrite is a secondary product of the mining extraction of coal. For these reasons, natural and synthetic pyrites have been proposed as active cathode materials in secondary lithium batteries...

Effect of Surface Energy on Pentacene Thin-Film Growth and Organic Thin Film Transistor Characteristics

In this study, we discuss pentacene-based organic thin films grown on a self-assembled monolayer (SAM)-treated dielectric with various functional groups and molecular lengths. The functional groups and molecular lengths on the dielectric surface were modified using a SAM treatment followed by ultra violet (UV) light exposure. Surface energy was used to observe the surface polarity variation dur...

Thin-Film Molecular Materials Based on Tetrametallic “Squares”: Nanoscale Porosity and Size-Selective Guest Transport Characteristics

Described are the preparation and functional characterization of nanocrystalline and/or amorphous thin films comprising of neutral “molecular squares” of the form [Re(CO)3(Cl)(μ-L)]4 (L ) difunctional imine or azine ligand). The films are strongly adherent, stable in aqueous media, and characterized by comparatively few pinhole defects. Electrochemical transport experiments show that the materi...

Porphyrin-Based Thin-Film Molecular Materials with Highly Adjustable Nanoscale Porosity and Permeability Characteristics.

Mesoporous thin films based on neutral, porphyrin-bridged, tetrarhenium "square" compounds (metallacycles) display permeability to molecules smaller than the dimensions of an individual square cavity, but blocking behavior toward larger species (see schematic representation). The characteristic permeant size cutoff can be systematically and predictably manipulated by decorating the walls of the...
