Learn about the levels of the atmosphere. Explore the main layers within the structure of the atmosphere: troposphere, stratosphere, mesosphere,...
Metal-organic layers (MOLs) are highly attractive for application in catalysis, separation, sensing and biomedicine, owing to their tunable framework structure. However, it is challenging to obtain comprehensive information about the formation and local structures of MOLs using standard electron microscopy...
Both of these structures also occur in Earth's ionosphere, where they can interfere with local and long-distance transmissions. Related: Photos: NASA's MAVEN mission to Mars Layers refer to areas where electrically charged plasma builds up in, well, layers. These formations often form suddenly ...
HFOs were first described in non-human primates in the mesial temporal lobe13 associated with information transfer between the hippocampus and extra-hippocampal structures14. Subsequently, HFOs were found in animal models of epilepsy11,15,16, and in human epileptic brain regions17,18,19,20. The ...

In the solar wind at 1 AU, coherent electrostatic waveforms in the ion acoustic frequency range (between the ion and electron plasma frequencies) have been recently observed by the WAVES/TDS instrument on WIND. Many of these structures have been interpreted in terms of Weak Double Layers (WDL)...
Understanding the role of these processes in the luminescence of dilute GaAs1-xBix QW structures facilitates the creation of highly efficient devices with reduced thermal sensitivity and low threshold current. 展开 关键词: GaAsBi heterostructures cladding layers photoluminescence ...
Dermis: The middle layer of the skin This is the layer responsible forwrinkles. The dermis is a complex combination ofbloodvessels,hairfollicles (skin structures that form hair),and sebaceous (oil) glands. Here, you'll findcollagenand elastin — two proteins that are necessary for skin health...
Excitonic insulators (EIs) arise from the formation of bound electron–hole pairs (excitons)1,2 in semiconductors and provide a solid-state platform for quantum many-boson physics3,4,5,6,7,8. Strong exciton–exciton repulsion is expected to stabilize condensed superfluid and crystalline phases by...
These three layers are the ones closest to the Sun. Tensioning of the final two layers is planned for tomorrow. “The membrane tensioning phase of sunshield deployment is especially challenging because there are complex interactions between the structures, the tensioning mechanisms, the cables and the...
