We aim to understand and exploit the factors (strain, composition, band structure etc.) that determine structure and function in the crystalline solid state. Our interest is in the balance between local crystal chemistry, strain and longer range order in a wide range of compositionally and/or displacively flexible crystalline solids. The principal experimental research tools used are solid stat...

The application of symmetry considerations to the theory of superconductivity has been considered further. The problem consists of extending the methods recently advanced (1) so as to include the interaction of the electrons with the lattice vibrations. (See Quarterly Progress Report, April 15, 1951.) It now appears that the difficulties which have been blocking progress are not of a formal mat...

A Comparison of Capacitive and Active Array Based Human Fingerprint Readers This paper addresses relative aspects of the two currently available all-solid-state technology solutions to the digital fingerprint identification problem. In the body of this report passing mention is made of some other approaches, and a very brief summary of the whole biometric technology set can be found in APPENDIX...

Solid-state drives (SSDs) composed of multiple flash memory chips are often deployed as a cache in front of a cheap and slow disks [5, 2, 7]. This provides the performance of flash with the cost of disk for large data sets, and is actively used by Facebook and others to provide low-latency access to petabytes of data [3]. An SSD-backed cache, though, is limited by its narrow block interface and...

Irradiation of biphenyl encapsulated in the cavities of a NaZSM-5 zeolite framework has been reported to result in the formation of an extremely long-lived radical cation. Here, we show that such zeolite encapsulated radical cations can act as irreversible one-electron oxidants for simple alkenes and dienes, in a solid-state analogue to solution-phase cosensitization. Compared to the well-known...

We demonstrated nanoscale solid-state thermal rectification. High-thermal-conductivity carbon and boron nitride nanotubes were mass-loaded externally and inhomogeneously with heavy molecules. The resulting nanoscale system yields asymmetric axial thermal conductance with greater heat flow in the direction of decreasing mass density. The effect cannot be explained by ordinary perturbative wave t...

By definition, solid state is that particular aggregation form of matter characterized by strong interaction forces between constituent particles (atoms, ions, or molecules). As a result, a solid state material has an independent geometric form (in contrast to liquids, which take the form of the container) and an invariant volume (in contrast to gases/vapors) in given temperature and pressure c...

A furan amino acid, inspired by the recently discovered proximicin natural products, was incorporated into the scaffold of a DNA-binding hairpin polyamide. While unpaired oligomers of 2,4-disubstituted furan amino acids show poor DNA-binding activity, furan (Fn) carboxamides paired with N-methylpyrrole (Py) and N-methylimidazole (Im) rings demonstrate excellent stabilization of duplex DNA as we...
