In situ TEM observation of magnetic materials

Microscopy Research and Technique, 2009
AbstractMagnetic nanostructures and thin films display novel magnetization reversal behavior as a function of size and shape, which makes them appropriate for a range of technological applications. The spatial resolution of in situ transmission electron microscopy techniques such as Lorentz TEM (LTEM) and off‐axis electron holography are well suited to

In-situ observation of colloidal crystallization

Progress in Crystal Growth and Characterization of Materials, 2016
Abstract We report contents of colloidal crystallization experiments in ISSCG-16. The participants produce two kinds of colloidal crystals, i.e., close-packed opal type crystals, and non-close-packed charged colloidal crystals. They can observe the crystallization processes by using optical microscopy and reflection spectroscopy.

In-Situ Observations of Dislocations in Lithium

Proceedings, annual meeting, Electron Microscopy Society of America, 1980
The alkali metals, as a unique class of elements in the periodic table, possess a number of interesting characteristics. Elements such as lithium and sodium are amenable to in situ TEM studies since dislocations can be generated and their motion activated by the thermal stress ...

In Situ Observation of Melting and Solidification

MRS Proceedings, 1999
AbstractMelting and solidification of metallic materials have been observed directly using an in-situ heating experiment in an electron microscope. In pure Al melting initiates at the surface, while in a eutectic alloy melting initiates preferentially at eutectic interfaces and grain boundaries.

In-situ observation of ettringite crystals

Journal of Crystal Growth, 2009
In-situ observation of growing ettringite crystals in solution has been carried out and the morphology change of ettringite has been investigated under various conditions. In particular, the acceleration behavior of ettringite growth in the presence of calcite, the cause of which is not yet understood, is examined.

In situ observation of secondary nucleation

Journal of Crystal Growth, 1986
Abstract Contact nucleation experiments on the (100) face of KH 2 PO 4 crystals have been performed using an advanced microscopic technique so that the contacting event and the results of the contact- secondary nucleation, disturbance of the step pattern and damage to the mother crystal-could be directly observed.

In situ observation of homogeneous nucleation of nanosized zeolite A

Physical Chemistry Chemical Physics, 2006
The formation of zeolite A (LTA) in the presence of tetramethylammonium cations is studied using in situ small angle and wide angle X-ray scattering (SAXS/WAXS) techniques. The SAXS measurements show the formation of homogeneous precursors 10 nm in size prior to the crystallization of LTA which were consumed during the crystallization. The crystal size

In-situ observation and formation mechanism of aluminum voiding

26th Annual Proceedings Reliability Physics Symposium 1988, 1988
An in situ observation equipment was used to investigate aluminum void formation. It was found that the voids are formed during heating and are hardly changed during cooling. The void growth can be described by an equation in which the total number of voids saturates to a certain value as a function of heating time.
