Fluorinated Polymer, Method of Making, and Use in Electrochemical Cell
Low specific capacity and low charge/discharge rate of current cathodic materials are the bottle-neck for the next generation electrochemical energy storage devices, particularly for “on-demand applications.” Current batteries rely on transition metal salts (e.g. LiMO2, LiMPO4) and mixed metal oxide lithium salts as cathodic materials. The...

Method of Growing Germanium Crystals
This new method uses a quartz shield to isolate the germanium that would otherwise be contaminated by the stainless steel chamber, insulation materials, or the graphite crucible. Doctors Mei and Wang also determined that use of a load scale can control the crystal diameter and ensure that all melted germanium is used in crystal production and thus removed...

Electron-Deficient Fluorous Porphyrins and Their Use in Organic Solar Cells
Fluorinated aromatics and related materials offer many advantages over non-fluorinated materials in a variety of different optoelectronic devices such as, but not limited to, organic light emitting diodes (OLEDs), organic field-effect transistors (OFETs), organic solar cells (OSCs), and dye-sensitized solar cells (DSSCs). These fluorinated materials...

Fluorinated ultra-thin film
Fluoropolymers have experienced widespread use as functional materials in applications ranging from water purification to energy storage. Production of large area, two-dimensional (2D), ultra-thin, semifluorinated polymer films is expected to have significant impacts on multiple fields. Some of these fields are organic electronics and optoelectronics...
