Spontaneous Raman scattering for simultaneous measurements of in-cylinder species [PDF]
, 2007 A technique for multi-species mole fraction measurement in internal combustion engines is described. The technique is based on the spontaneous Raman scattering. It can simultaneously provide the mole fractions of several species of N-2, O-2, H2O, CO2 and

Spatially Tailorable Liquid Crystalline Elastomer Alignment During Digital Light Process 3D Printing
Advanced Functional Materials, EarlyView.Here, we report the fabrication of 3D printable liquid crystalline elastomer (LCE) structures with spatially tailorable alignment domains within the same layer. This work addresses the long‐standing challenge of preparing complex 3D LCE architectures with patterned functional domains to achieve nonlinear deformations. Fabrication of multi‐domains in 3D

Single ion heat engine with maximum efficiency at maximum power [PDF]
, 2012 We propose an experimental scheme to realize a nano heat engine with a single ion. An Otto cycle may be implemented by confining the ion in a linear Paul trap with tapered geometry and coupling it to engineered laser reservoirs. The quantum efficiency at
