Long-wavelength broad band infrared photodetector using four asymmetric quantum wells
(ELSEVIER SCIENCE BV, 2007)
A theoretical investigation of GaAs/AlGaAs infrared detector consisting of four asymmetric quantum wells is presented. Each well is designed to yield absorption and a photoresponse at peak wavelengths of 7.9, 9.2, 10.4, ...
Muscle ischaemia in rats may be relieved by overload-induced angiogenesis
(CAMBRIDGE UNIV PRESS, 2002)
Alleviation of muscle ischaemia by improving capillary supply has proved difficult, possibly reflecting the inability to substantially increase blood flow. We reasoned that muscle overload, which induces angiogenesis in ...
Flotation and entrainment behavior of minerals in talc-calcite separation
(BLACKWELL PUBLISHING, 2005)
The main aim of a flotation process is to recover the valuable part of the ore with minimum gangue contamination by different mechanisms, such as entrainment. In this study, the flotation rate and recovery of talc and ...
