So-called bottom-up fabrication methods aim to assemble and integrate molecular components exhibiting specific functions into electronic devices that are orders of magnitude smaller than can be fabricated by lithographic techniques. Fundamental to the success of the bottom-up approach is the ability to control electron transport across molecular components. Organic molecules containing redox ce...

Acute reactions to the haemodialysis membrane have been reported as early as 1975 [1]. Because their severity is usually mild, their frequency is probably widely underestimated. However, these reactions may occasionally be life-threatening [2]. The aetiological mechanisms of these reactions are multiple, the best characterized being allergy to ethylene oxide and combined exposure to the polyacr...

The encapsulation of graphite-type carbon wires in the regular, 3-nanometer-wide hexagonal channels of the mesoporous host MCM-41 is reported. Acrylonitrile monomers are introduced through vapor or solution transfer and polymerized in the channels with external radical initiators. Pyrolysis of the intrachannel polyacrylonitrile results in filaments whose microwave conductivity is about 10 times...
