What ist Micro Ed in electron microscopy?5 answersMicrocrystal electron diffraction (MicroED) is a cryo-TEM technique used to determine the atomic structure of molecules. It involves continuously tilting a small crystal in the cryo-TEM while recording diffraction information. MicroED can be carried out on crystals in the nanometer size range, making it useful for studying macromolecular structures such as proteins and peptides. MicroED is analogous to X-ray crystallography but utilizes a transmission electron microscope as the base platform. It has been used in various fields such as natural products research and drug discovery, and has been successful in determining structures of proteins, small molecules, and peptides. Recent advances in hardware and methods development have improved the data quality, allowing even macromolecular structures to be determined ab initio. MicroED can provide accurate structural information on hydrogen atoms and non-covalent hydrogen bonding interactions in macromolecules, which is important for drug discovery and understanding protein structure and function. Electron diffraction is a disruptive technology that enables the characterization of nanometre-sized crystals, opening up new perspectives for chemical, pharmaceutical, and advanced materials research.

Finally, a study demonstrated a monolithic TPMS that integrates a 3-axis accelerometer, capacitive pressure sensor, and temperature sensor on a single chip.
Microtiter plate (MtP) what is their applications?5 answersMicrotiter plates (MtPs) have various applications in screening and process development of microorganisms. They are commonly used for high-throughput and small-scale microbial culture. MtPs can be optimized for specific work, such as the fermentation culture of docosahexaenoic acid (DHA) producing strains. Computational fluid dynamics (CFD) technology is used to develop novel MtPs that provide high oxygen supply and optimal mixing effects, surpassing conventional methods like shake flasks. Additionally, microfluidic concepts compatible with MtPs, such as WellProbe, can improve assay kinetics and provide more sensitive and informative results for surface assays like ELISA. MtPs are also used for assessing the biofilm inhibition and eradication capacities of antibiofilm agents against adherent bacterial biofilms. Furthermore, multi-well MtPs are designed for high-throughput screening of piercing-sucking arthropods, such as insects exposed to various compounds.
What is the micro-strain equation?5 answersThe micro-strain equation is a fourth order non-linear partial differential equation that describes the propagation of strain waves in micro-structured solids. It is a generalization of the Boussinesq equation with dual dispersion. Several new exact solutions to this equation have been obtained using different methods, such as the F-expansion method, the generalized exponential rational function method, and the modified extended direct algebraic method. These methods have allowed for the derivation of traveling wave solutions without the need for initial integration. The micro-strain equation is important in the study of solid physics and has applications in various physical phenomena.
What is the microplate reader?4 answersA microplate reader is a device used for measuring light emitted from a sample in a microplate. It consists of a housing, light projection units, light reception units, and light guide paths. The microplate reader can be used to analyze fluorescent sensor signals from colonies grown on solid media. It offers improved sensitivity and dynamic range compared to imaging approaches for analyzing reporter gene expression and promoter activity in microbial colonies. The microplate reader can also capture signals from ratiometric fluorescent reporter proteins with high sensitivity, allowing for the analysis of internal pH and redox states in colonies. This device enables comprehensive phenotypic screenings of microbial colonies, facilitating the development of new strains for metabolic engineering and systems biology. Additionally, a microplate reader can be used for high-throughput assays in various analytical fields, such as surface-enhanced Raman scattering (SERS) analysis.
