Operando spectroscopy is a logical technological progress in situ studies. Catalyst scientists would ideally like to have a "motion picture" of each catalytic cycle, whereby the precise bond-making or bond-breaking events taking place at the active site are known; [ 7 ] this would allow a visual model of the mechanism to be constructed.
In situ [a] is a Latin phrase meaning "in place" or "on site", derived from in ('in') and situ (ablative of situs, lit. ' place '). [3] The term refers to the examination of phenomena or objects within their original place or context. This methodological approach, used across diverse disciplines, maintains contextual integrity essential for ...
Experiments which use these environments are called in situ and allow the characterization of atomic- to nano-scale phenomena which are inaccessible to most other characterization tools. In operando measurements are designed to mimic the real working conditions of a material as closely as possible. [8]
The resolution that can be achieved with in situ Hi-C can be up to 950 to 1000 bp compared to the 1 to 10 Mb resolution of standard Hi-C and the 100 kb resolution of DNase Hi-C. [3] [4] [14] [19] While standard Hi-C makes use of a 6-bp cutter such as HindIII for the restriction digest step, in situ Hi-C uses a 4-bp cutter such as MboI or its ...
In polymer chemistry, in situ polymerization is a preparation method that occurs "in the polymerization mixture" and is used to develop polymer nanocomposites from nanoparticles. There are numerous unstable oligomers ( molecules ) which must be synthesized in situ (i.e. in the reaction mixture but cannot be isolated on their own) for use in ...
In situ hybridization (ISH) is a type of hybridization that uses a labeled complementary DNA, RNA or modified nucleic acid strand (i.e., a probe) to localize a specific DNA or RNA sequence in a portion or section of tissue or if the tissue is small enough (e.g., plant seeds, Drosophila embryos), in the entire tissue (whole mount ISH), in cells ...
In situ chemical oxidation (ISCO), a form of advanced oxidation process, is an environmental remediation technique used for soil and/or groundwater remediation to lower the concentrations of targeted environmental contaminants to acceptable levels.
A tomato greenhouse in the Netherlands. The advantage of mesocosm studies is that environmental gradients of interest (e.g., warming temperatures) can be controlled or combined to separate and understand the underlying mechanism(s) affecting the growth or survival of species, populations or communities of interest.
