“…In the present work as well as in ref. [13] we obtain these potentials as solutions of the corresponding Poisson equations. The problem of the boundary conditions for the Poisson equation as well as the problem of simultaneously solving Poissons equations on the same meshes with Schrödinger-like equations for the wave functions ψ µ (z, ρ) have been discussed in ref.…”

The ground and some excited states of the Li atom in external uniform magnetic fields are calculated by means of our two-dimensional mesh Hartree-Fock method for field strengths ranging from zero up to 2.35 ϫ10 8 T. With increasing field strength, the ground state undergoes two transitions involving three different electronic configurations: for weak fields, the ground-state configuration arises from the field-free 1s 2 2s configuration; for intermediate fields, it arises from the 1s 2 2p Ϫ1 configuration, and in high fields, the 1s2 p Ϫ1 3d Ϫ2 electronic configuration is responsible for the properties of the atom. The transition field strengths are determined. Calculations on the ground state of the Li ϩ ion allow us to describe the fielddependent ionization energy of the Li atom. Some general arguments on the ground states of multielectron atoms in strong magnetic fields are provided.

“…Some of the other additives such as maleic anhydride [125] and 1-butene-2,3,4-tricarboxylic anhydride [126] improve the heat resistance of the cyanoacrylic bonds. Generally, a rise in temperature beyond 150°C had an adverse effect on the adhesive bonds on all the metals, leading to total rupture after 3 h. With aluminum, a reduction in the bond strength occurred at a temperature between 60 and 100°C, with steel at 100°C; while for copper and brass a higher initial strength was observed followed by a rapid decrease in thermal stability [127]. Incorporation of hydrolyzable or condensed tannins also helps to increase the heat resistance and adhesion [ 128].…”

Although rapid and reliable, the established sensing methods can be limited to narrow concentration ranges, and still require hazardous, and unstable reagents.…”

Evaluation of novel Griess-reagent candidates for nitrite sensing in aqueous media identified via molecular fingerprint searching

et al. 2019

The Griess reaction is the most often exploited colorimetric method for the quantitative analysis of nitrite in aqueous media. The application of the currently used reagents are associated with limitations (e.g. linear response range). Herein, molecular fingerprint searching on well-known Griess-reagents was used as a tool for the identification of structurally similar, new reagent candidate molecules. Rapid and highthroughput experimental evaluation of the newly identified Griess-reagent candidates revealed that 14 of the 18 tested reagent candidates had equal or superior response displaying broader linear ranges and/or increased response gradient against various nitrite concentrations in aqueous media when compared to the parent compounds at room temperature.Scheme 1 Example of a Griess reaction for the detection of nitrite in aqueous media.
