摘要:
The present invention includes a composition comprising an alkyne-based substrate, an azide-based substrate, a Cu(II) salt and a photoinducible reducing agent. The present invention further includes a method of immobilizing a chemical structure in a given pattern onto a section of the surface of a solid substrate, using the photoinducible Cu(I)-catalyzed azide-alkyne cycloaddition Click reaction.
摘要:
The invention includes a novel light-activated polymerizable composition, wherein reversible crosslinks may be converted into irreversible crosslinks using a fully controllable physical and/or chemical process. The invention further includes methods of photofixing a light sensitive material or patterning an article comprising a light sensitive material.
摘要:
A mobile personal alarm and warning system for monitoring temperature around the designated user integrated with a vehicle access and warning controls. The system utilizes controls and actuation mobile self-contained modules that monitor the ambient temperature around the designated user and transmits a warning activation signal to the mobile control unit carried by the primary user as an alert condition. Proximity sensor provisions are provided to assure response range between the modules as well as enabling two-way radio communication protocols.
摘要:
The invention provides methods of reducing shrinkage stress in cross-linked polymerized materials by combining an addition-fragmentation chain transfer additive with a resin system prior to polymerization. The methods of the invention can improve the performance of conventional resin systems by reducing the shrinkage stress without significantly degrading the mechanical properties of the polymerized material. The shrinkage stress in the crosslinked polymeric materials produced by the methods of the invention may be from 25% to 75% of that of a control material produced by polymerization of the resin system alone to the same conversion.
