Digital wires

Digital wires

E lectrical wires transport energy and information and often both. For example, electrical power cords deliver electrical energy from wall outlets to computers, whereas Ethernet cable transports information in the form of electrical pulses from the internet modem to the computer and back. USB cables are used to both charge the battery of MP3 players and to load digital music on the player. Desp...

Evaluation of reversal osteofixation using K-wires in digital replantation.

INTRODUCTION Modified, reversal technique of fixation in digital replantation using K-wires was analyzed. The results obtained from the standard technique and reversal technique of fixation using K-wires were compared. OBJECTIVE The aim was to compare the results of osteofixation using K-wires in digital replantation when either standard or reversal, modified technique was used. METHODS A r...

Quantum Wires

Optical 'shorting wires'.

Connecting lumped circuit elements in a conventional circuit is usually accomplished by conducting wires that act as conduits for the conduction currents with negligible potential drops. More challenging, however, is to extend these concepts to optical nanocircuit elements. Here, following our recent development of optical lumped circuit elements, we show how a special class of nanowaveguides f...

Semiconducting polymer quantum wires

Semiconducting polymer heterostructures with strong two-dimensional quantum confinement of excitons are prepared by self-assembly of two conjugated polymers in binary blends. Exciton confinement effects in the semiconducting polymer quantum wires were observed at room temperature by photoluminescence excitation and photoluminescence spectroscopies and by electric field-induced photoluminescence...
