Quantitative structured-illumination phase microscopy
Applied Optics, 2007We introduce a quantitative phase imaging method for homogeneous objects with a bright field transmission microscope by using an amplitude mask and a digital processing algorithm. A known amplitude pattern is imaged on the sample plane containing a thick phase object by placing an amplitude mask in the field diaphragm of the microscope.

Structural Phase Transitions in CaC2
Chemistry, 2001Pure CaC2, free of CaO impurities, was obtained by the reaction of elemental calcium with graphite at 1,070 K. By means of laboratory X-ray and synchrotron powder diffraction experiments, the phase diagram was investigated in the temperature range from 10 K to 823 K; this confirmed the literature data that reported the partial coexistence of up to four

Phase transitions appear in any scenario analyzed in physics, describing transition of distinct phases of matter, which ranges from daily life experience to more exotics realms as quantum physics or cosmology (Stanley in Introduction to phase transitions and critical phenomena, Clarendon Press, Oxford, 1971, [1], Huang in Statistical mechanics, Wiley ...

This chapter describes the iron-carbon phase diagram, its modification by alloying elements, and the effect of carbon on the chemistry and crystallography of austenite, ferrite, and cementite found in Fe-C alloys and steels. It also lays the groundwork for understanding important metallurgical concepts, including solubility, critical temperature ...

Lipid Phases: Structure and Structural Transitions
Annual Review of Physical Chemistry, 1974Lipids as a class encompass a large family of chemical compounds characterized by the presence in the same molecule of a hydrophilic and a hydrophobic part linked together by bonds sufficiently flexible to yield a rather independent behav ior. In the examples mentioned in this review the hydrophobic moiety is formed by one or two hydrocarbon chains of

Structural Phase Transformation
1994Examples of phase transformations (transitions) in various materials are first introduced and the difference between the continuous and discontinuous transformation is outlined. The difference is theoretically analyzed by combining Ehrenfest’s criterion and Landau’s formulation and graphically shown by the G—T—η; diagrams.

Structurally integrated phased arrays
2011 Aerospace Conference, 2011This paper will discuss the benefits and challenges of integrating large structural apertures or antennas into aircraft structure.12 Current generation parasitic (non-load bearing) antennas are limited in size and installation location by vehicle airframe and flight characteristics.
