Low-Surface-Energy Photoresist as a Medium for Optical Replication
In these applications, a master surface relief is created by exposing photoresist through a suitably designed grayscaleintensity mask. Development of the resist produces a profiled surface according to the mask transmittance and exposure. Components can be replicated from this master by contact molding; this requires a release layer to insure the master and replicant can be separated without da...
متن کاملAccuracy of replication for non-destructive surface finish measurement
Surface replication has been widely used in aerospace, automotive and other industries as a non-destructive method for examination and assessment of either surfaces difficult to be accessed by measurement tools or parts difficult to be dismantled for measurement. The fidelity and accuracy of the replication is one of the major concerns in actual applications. This paper presents a comprehensive...
متن کاملReplication of Leaf Surface Structures for Light Harvesting
As one of the most important hosts of natural light harvesting, foliage normally has complicated surface structures to capture solar radiances. Bio-mimicking leaf surface structures can provide novel designs of covers in photovoltaic systems. In this article, we reported on replicating leaf surface structures on poly-(methyl methacrylate) polymers to prompt harvesting efficiencies. Prepared via...
متن کاملCell surface heparan sulfate promotes replication of Toxoplasma gondii.
Previous work suggests that cell surface heparan sulfate acts as a receptor for the Apicomplexan parasite Toxoplasma gondii. Using Chinese hamster ovary cell mutants defective in heparan sulfate biosynthesis, we show that heparan sulfate is necessary and sufficient for infectivity. Further, we demonstrate that the parasite requires N sulfation of heparan sulfate initiated by N-deacetylase/N-sul...
متن کاملThe dimer-dimer interaction surface of the replication terminator protein of Bacillus subtilis and termination of DNA replication.
The replication terminator protein (RTP) of Bacillus subtilis causes polar fork arrest at replication termini by sequence-specific interaction of two dimeric proteins with the terminus sequence. The crystal structure of the RTP protein has been solved, and the structure has already provide valuable clues regarding the structural basis of its function. However, it provides little information as ...
