Learn about the structure of the sun, the layers of the sun, solar winds and solar flares, and sunspots. Understand the structure of the sun in a...
In particular, the magnetic structure of LaMn2(Ge1−xSix)2 is strongly affected by the unit cell parameter c, which is related to the distance between adjacent Mn layers. Commensurate antiferromagnetic layers and a canted ferromagnetic structure dominate the Si-rich part of the solid solution,...
Oceans cover nearly three-quarters of the earth's surface, yet around 95 percent of them have not been explored because the marine environment is hostile for humans. Special equipment is needed for research on the ocean floor because of the cold, high-pressure, and low-oxygen atmosphere. The...
Carbon cycle is a process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.
Depending on the type of samples that was synthesised, different methods were used that are summarised in Table 1. The suspensions were filtered under an inert atmosphere and the precipitates were analysed by several techniques: X-ray diffraction (XRD) at a wavelength λ(CoKα1)=0.1789nm, ...
Each phospholipid molecule is made up of ahydrophilic(or water-loving) phosphate head, plus twohydrophobic(or water-hating) fatty acids. The double membrane forms when two layers of phospholipids line up tail to tail, with the fatty acids forming the inner layer of the membrane and the phospha...
Surface layers were removed by grinding, and samples were finally cleaned with ethanol. The actual chemical Results The existence and crystal structures of all phases including the two modifications of the Laves phase reported in the literature were confirmed by XRD of powdered alloy samples (see ...
Superconductivity (SC) with the suppression of long-range antiferromagnetic (AFM) order is observed in the parent compounds of both iron-based and cuprate superconductors. The AFM wave vectors are bicollinear (π, 0) in the parent compound FeTe different from the collinear AFM order (π, π) ...
In order to match observed properties of the solar cycle, flux-transport dynamo models require the toroidal magnetic flux to be stored in a region of low magnetic diffusivity, typically located at or below the bottom of the convection zone. We infer the turbulent magnetic diffusivity affecting the...
The rock layers of the Grand Canyon are the oldest at the bottom and get younger moving up. Fossils within the layers help scientists understand how life on Earth developed. The study of rock layers, orstrata, is calledstratigraphy. Geologists study the layers to learn more about the history...
