As a maglev levitates with a small air gap and runs very fast, securing the levitation system's stability is crucial. Thus, the high-performance decoupling control between the propulsion control system and the levitation system is of critical importa

We describe a photolithographic method for the direct modification and micropatterning of the surface chemical structure of self-assembled monolayers. End-functional azobenzene alkanethiols are designed and synthesized so that, when self-assembled on

Photoremovable protecting groups based on intramolecular electron transfer have been synthesized and studied. One molecule contains a N,N-dimethylaniline chromophore covalently linked to a phenacyl ester of acetic acid. UV photolysis of this molecule

The electron transfer mediated photochemical release of alcohols, phosphates and diacids is examined. The alcohols can be protected as mixed phenacyl carbonate esters. Irradiation of mixtures containing electron donating sensitizers and phenacyl alky

Phenacyl esters (benzoylmethyl esters, PhCOCH2OCOR) release carboxylic acids upon photolysis using photosensitizers that are good one-electron donors in the excited state. Herein it is demonstrated that this procedure can be used to control the wa

The use of 157 nm as the next lower wavelength for photolithography for the production of semiconductors has created a need for transparent and radiation-durable polymers for use in soft pellicles, the polymer films which protect the chip from partic

We report a simple photolithographic approach for the creation and micropatterning of chemical functionality on polymer surfaces by use of surface-active block copolymers that contain protected photoactive functional groups. The block copolymers self
