Endomicroscopy is a technique for obtaining histology-like images from inside the human body in real-time, [1] [2] [3] a process known as ‘optical biopsy’. [ 4 ] [ 5 ] It generally refers to fluorescence confocal microscopy , although multi-photon microscopy and optical coherence tomography have also been adapted for endoscopic use.
This is a list of unsolved problems in chemistry. Problems in chemistry are considered unsolved when an expert in the field considers it unsolved or when several experts in the field disagree about a solution to a problem.
Like its lighter congener nickel(II) fluoride, PdF 2 adopts a rutile-type crystal structure, [2] [3] containing octahedrally coordinated palladium, which has the electronic configuration t 6 2g e 2 g. This configuration causes PdF 2 to be paramagnetic [4] due to two unpaired electrons, one in each e g-symmetry orbital of palladium.
As the atoms of interacting molecules (or of different parts of the same molecule - intramolecular BSSE) [1] [2] approach one another, their basis functions overlap. Each monomer "borrows" functions from other nearby components, effectively increasing its basis set and improving the calculation of derived properties such as energy . [ 3 ]

In coordination chemistry and crystallography, the geometry index or structural parameter (τ) is a number ranging from 0 to 1 that indicates what the geometry of the coordination center is. The first such parameter for 5-coordinate compounds was developed in 1984. [1] Later, parameters for 4-coordinate compounds were developed. [2]
In computational chemistry, spin contamination is the artificial mixing of different electronic spin-states.This can occur when an approximate orbital-based wave function is represented in an unrestricted form – that is, when the spatial parts of α and β spin-orbitals are permitted to differ.
[1] [2] [6] CLE can detect and distinguish the stomach pit patterns to identify the disease in accordance with the Miami classification, which was refined in 2016 to include both pit patterns and the architecture of blood vessels. [1] [2] [8] [9] The refined classification allows clinicians to differentiate between neoplastic and non-neoplastic ...
