Label-Free Optical Detection of DNA Translocations through Plasmonic Nanopores

Solid-state nanopores are single-molecule sensors that hold great potential for rapid protein and nucleic-acid analysis. Despite their many opportunities, the conventional ionic current detection scheme that is at the heart of the sensor suffers inherent limitations. This scheme intrinsically couples signal strength to the driving voltage,...

Buckling Strength of Plywood, Results of Tests and Design Recommendations

Tests were carried out on 100 specimens of Canadian Douglas fir plywood to verify that reasonably good agreement exists between the buckling theories and the actual behaviour of plywood. From load-deflection curves values for a critical buckling strength can be determined, which are in good agreement with theoretical values in the case of simply...
