Topological defects: These are imperfections in the structure of a material that arise when its internal arrangement (lattice or order parameter) cannot be perfectly aligned.Resistive switching is a sudden transition between insulating and metallic states triggered by an electric field.When V2O3 temperature is changed from high to low, the structure changes from rhombohedral shape to less symmetric...
Summary: study of Au, Ag and Cu- behave as superconductors
Density Of State(DOS) is a function of energy, It shows how many states exist for electrons at each possible energy level. In bulk metals, DOS near the Fermi level (the highest occupied energy level at absolute zero) is generally constant.Quantum confinement is the phenomenon that occurs when the thickness of a metallic film becomes comparable to the wavelength of the electrons in the material....
Summary: High temperature effect on Molybdenum disulphide
Scientists measured the displacement cross section of Sulphur atoms in MoS2 at temperatures up to 550◦C using scanning transmission electron microscopy at acceleration voltages of 60 and 90 keV. At a temperature of 150◦C, the displacement cross section of S atoms increased compared to room...
Overview: Magnetic Field for Jupiter and Neptune Class exoplanets
Dynamo is the process by which a planetary magnetic field is generated through the movement of electrically conductive materials within the planet's interior. The dynamo region is identified based on the magnetic Reynolds number.At the top of this region, the maximum magnetic field is where...
Summary of Article about Tests of the Hard X-ray Imager
The objective of HXI is to investigate how energy from the sun is released in solar flares.The relative displacement and rotation were tested from assembly to on-orbit operation and must be maintained under 36 μm and 10 arcsecs.When HXI reaches a thermal balanced state, further deformation measurements are done and collimator alignment is tested which is essential for accurate imaging.Deformation...
Overview : Non newtonian fluid flow rate, viscosity, pressure drop
In non-monotonic flow, the graph of flow rate versus shear stress or pressure often forms an S-shaped curve. Initially, the flow rate increases with stress. At a certain threshold, further increases in stress cause the flow rate to drop. fluid can exhibit two different shear rates at the same...
Key Points of Article about Measuring gravitational waves by graphene
Current detectors can only capture low-frequency gravitational waves.By using graphene, higher frequency gravitational waves can be detected and size of detector also reduced. Here relative intensity varies when gravitational waves are measured.As a gravitational wave propagates through a crystal lattice,...
Equations Used for measuring Exoplanet parameters
In recent article, brightness (flux) of the target star and the reference stars has been measured as analog digital units (ADU). The duration of a planetary orbit𝑅𝑠 is the star radius, 𝑅𝑝 is the planet radius, 𝑀𝑠 is the star mass, 𝑀𝑝 is the planet mass, 𝐺 is the gravitational constant,...
