For more than fifteen years, III-nitrides have become the materials of choice for the realization of optoelectronics devices operating in the visible-UV spectral range. Yet, while nitride-based technology has truly exploded, the structural quality of this ...
Organic semiconductors technology has only recently started to merge with biology and medicine, especially in the field of polymeric coatings as protective layers for artificial devices. Very few examples, however, report the use of semiconducting polymers ...

We present a set of simple techniques for key establishment over a radio link in peer-to-peer networks. Our approach is based on the Diffie-Hellman key agreement protocol, which is known to be vulnerable to the ``man-in-the-middle" attack if the two users ...
Recently, two e-mail protocols were proposed claiming to provide perfect secrecy. These protocols use authentication and (Diffie-Hellman) key-exchange techniques, and as such, other standard security criteria besides perfect forward secrecy include key-rep ...
The Cu-catalyzed synthesis of skipped 1,4-dienes from allylic acetates and vinyl-Grignard reagents is key to bidirectional modifications of acyclic terpene acetates. As a result, trisubstituted double bond containing subunits can be readily transferred int ...
Since the late 1960s, synchrotron-based experimental techniques have been playing a key role in semiconductor research. Major milestones include the observation of intrinsic and extrinsic surface and interface states, the study of interface formation proce ...
Single photon emitters often rely on a strong nonlinearity to make the behavior of a quantum mode susceptible to a change in the number of quanta between one and two. In most systems, the strength of nonlinearity is weak, such that changes at the single qu ...
Biosensors are heterogenous devices, incorporating biological struc- tures combined with electronics, optical or other readout systems. They have been developed for detecting different biomolecules and/or pathogens and represent a key technology for advanc ...
Despite many good (secure) key agreement protocols based on public-key cryptography exist, secure associations between two wireless devices are often established using symmetric-key cryptography for cost reasons. The consequence is that common daily used s ...
