Spectroelectrochemical Determination of Förster Radii for Triplet‐Polaron Quenching in Phosphorescent Organic Light‐Emitting Diodes

Advanced Functional Materials, EarlyView.
Phosphorescent OLEDs suffer from efficiency roll‐off due to triplet‐polaron quenching (TPQ). This study demonstrates for a large set of host‐guest combinations a spectroelectrochemical method to measure the absorption of charged molecules, enabling determining TPQ Förster radii (2.5–4 nm) from the spectral overlap.

Patterned Assembly of Transition Metal Dichalcogenide/Graphene Heterostructures via Direct Laser Writing

Advanced Functional Materials, EarlyView.
The fabrication of patterned transition metal dichalcogenide (TMD)/graphene heterostructures via direct laser writing reveals new interface chemistry and enables efficient, customizable assembly. Selective laser irradiation of functionalized TMD/graphene triggers localized reactions, forming chemically modified interfaces.

Carbon/carbon supercapacitors

Journal of Energy Chemistry, 2013
Supercapacitors, or electrochemical capacitors, are a power storage system applied for harvesting energy and delivering pulses during short periods of time. The commercially available technology is based on charging an electrical double-layer (EDL), and using high surface area carbon electrodes in an organic electrolyte.

Carbon-carbon composite

Materials Science and Engineering: A, 1997
Abstract A problem in the production of carbon-carbon composites from carbon fiber reinforced thermoset composites through pyrolization is the cracking of the matrix due to internal stresses caused by the large shrinkage of the pyrolizing matrix and the simultaneous expansion of the fibers.

Carbon–carbon coupling in biotransformation

Current Opinion in Biotechnology, 2003
Most research on carbon-carbon coupling biocatalysts is still carried out on aldolases and ketolases from carbohydrate metabolism; the emphasis of these studies is on the synthesis of optically active compounds. A major target is to avoid expensive starting materials and to broaden the range of possible products.

Carbon-Carbon Composites [PDF]

, 1998
Carbon-carbon (CC) materials are a generic class of composites similar to the graphite/epoxy family of polymer matrix composites. These materials can be made in a wide variety of forms, from one-dimensional to n-dimensional, using unidirectional tows, tapes, or woven cloth (Fig. 15.1).

Carbon-Carbon Composites

2001
Since their introduction in the early 1970’s, carbon fibre reinforced carbon (CC) composites have become a well-established form of engineering carbon and find widespread application in both aerospace and materials processing industries. In fact, CC composites are notable as being among the most successful of the “brittle matrix composite” engineering ...
