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.
Surface-Science-Based Model Catalysts: Prof. Rupprechter's work on planar model catalysts aims to understand fundamental processes that occur on catalytic surfaces via in situ/operando surface spectroscopy and microscopy, [10] bridging both the materials and pressure gaps. [11]
The beamlines at NSLS-II are grouped into five science programs: hard X-ray scattering & spectroscopy, imaging and microscopy, structural biology, soft X-ray scattering and spectroscopy, and complex scattering. These programs group beamlines together that offer similar types of research techniques for studying the behavior and structure of matter.
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]
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 ...
[12] [13] Zitoun and colleagues were the first to introduce the use of electron magnetic measurements in post-mortem analyses of Li-ion batteries [14] and the first group to publish the operando electron magnetic measurements. [15] These in-situ measurements allowed proposing a new electrochemical mechanism for the high energy density anodic ...
The Reverse Monte Carlo (RMC) modelling method is a variation of the standard Metropolis–Hastings algorithm to solve an inverse problem whereby a model is adjusted until its parameters have the greatest consistency with experimental data.
Laser spectroscopic techniques have been used for many different applications. One example is using laser spectroscopy to detect compounds in materials. One specific method is called Laser-induced Fluorescence Spectroscopy, and uses spectroscopic methods to be able to detect what materials are in a solid, liquid, or gas, in situ. This allows ...
