A High-Efficiency Neutron Detector [PDF]

Nature, 1950
THE recent development of scintillation counters as high-efficiency detectors of gamma-radiation makes attractive the possibility of detecting neutrons by means of the γ-rays produced in many neutron-induced reactions. Particularly interesting is the detection of the 480-keV. γ-ray given off by the excited lithium-7 in the reaction:

High-efficiency dielectrophoretic ratchet

Physical Review E, 2012
Brownian ratchets enable the use of thermal motion in performing useful work. They typically employ spatial asymmetry to rectify nondirected external forces that drive the system out of equilibrium (cf. running marbles on a shaking washboard). The major application foreseen for Brownian ratchets is high-selectivity fractionation of particle or molecule

High-efficiency server design [PDF]

Proceedings of 2011 International Conference for High Performance Computing, Networking, Storage and Analysis, 2011
Large-scale data centers consume megawatts in power and cost hundreds of millions of dollars to equip. Reducing the energy and cost footprint of servers can therefore have substantial impact. Web, Grid, and cloud servers in particular can be hard to optimize, since they are expected to operate under a wide range of workloads.
