Gatan Mud Volcanoes, Oman Sea Coast in Southwestern Hormozgan, Iran
Iran's mud volcanoes are clearly visible on the coastal plains of the Oman and Caspian Seas. There are 30 Gatan Mud Volcanoes located in the southeast of Iran: 15 of which are located between Jask and Minab in Hormozgan province, nine are between Chabahar and Jask Ports, and another six are between Chabahar and the Iran-Pakistan border in Sistan and Balouchestan Province. After some studies and...
متن کاملAd Hoc Determination of Local Misorientations and Boundary Planes between Grains in TEM by a Dedicated Software Package Developed for the Gatan DigitalMicrograph Platform
Mechanical and electrical properties of materials are often highly dependent on the crystallographic direction by which they are measured. For properties being measured over spatially limited extents, grain boundaries (GBs) present in crystals can greatly complicate interpretation of results. It is therefore necessary to characterize GBs in terms of the rotation of a particular vector in one gr...
متن کاملHigh resolution EELS using monochromator and high performance spectrometer: comparison of V2O5 ELNES with NEXAFS and band structure calculations.
Using single crystal V2O5 as a sample, we tested the performance of the new aberration corrected GATAN spectrometer on a monochromatised 200 kV FEG FEI (S)TEM. The obtained V L and O K ELNES were compared with that obtained in a common GATAN GIF and that in the new spectrometer, without monochromatised beam. The performance of the new instrumentation is impressive: recorded with an energy-resol...
متن کاملQuantitative characterization of electron detectors for transmission electron microscopy.
A new generation of direct electron detectors for transmission electron microscopy (TEM) promises significant improvement over previous detectors in terms of their modulation transfer function (MTF) and detective quantum efficiency (DQE). However, the performance of these new detectors needs to be carefully monitored in order to optimize imaging conditions and check for degradation over time. W...
متن کاملDirect observation of domain walls in NiFe films using high-resolution Lorentz microscopy
A novel approach to observe the interaction between magnetic domain wall and nanoscale microstructural features is demonstrated. The method is based on Focault mode Lorentz microscopy and utilizes a Gatan energy image filter to provide additional magnification. A postexperimental image processing technique was applied to separate lattice diffraction from that induced by magnetic domains. The ef...
