General Description

Cesium chloride is a chemical compound with the formula CsCl. It is a salt that is composed of cesium and chlorine ions in a 1:1 ratio. Cesium chloride is widely used in laboratory research for the preparation of density gradients in centrifugation, as well as for the purification of DNA. It is also used in the preparation of cesium-based compounds and as a source of cesium ions in a variety of chemical reactions. In addition, cesium chloride has been investigated for its potential in cancer therapy, as it has been shown to disrupt the ionic balance in cancer cells, leading to their destruction. However,

Check Digit Verification of cas no

The CAS Registry Mumber 7647-17-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,4 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7647-17:
(6*7)+(5*6)+(4*4)+(3*7)+(2*1)+(1*7)=118
118 % 10 = 8
So 7647-17-8 is a valid CAS Registry Number.

Time-dependent transformation routes of perovskites CsPbBr3and CsPbCl3under high pressure

Katrusiak, Andrzej,St?hl, Kenny,Szafrański, Marek

, p. 10769 - 10779 (2021/05/14)

All-inorganic halide perovskites are prospective materials for diverse applications in photovoltaic and optoelectronic devices. Their high performance is associated with good operational stability, which is the key problem of hybrid organic-inorganic perovskites. However, for these materials only fragmentary information is available on the mechanical robustness and response to external stress, fundamentally important for strain engineering in multilayers, pressure-assisted technologies, and flexible panels applications. Here we show that all-inorganic perovskites CsPbX3 (where X = Cl, Br) undergo various types of pressure-induced transformations, including reversible phase transitions, irreversible chemical reactions reducing the dimensionality of PbX6 frameworks, and amorphization. The transformation routes depend on the mode of the applied stress and are related to the kinetics of transitions to the most stable phases. The slow-kinetics transformations in a moderate pressure range of technological importance, between 0.5 and 1.5 GPa, can require days or even weeks, depending on the sample quality and external stimuli. The pressure-induced narrowing and widening of energy gaps has been explained by the mechanism combining Pb-X bond lengths and PbX6 octahedra tilts with the electronic structure of the crystals.

Soluble diamagnetic model for malaria pigment: Coordination chemistry of gallium(III)protoporphyrin-IX

Bohle, D. Scott,Dodd, Erin L.,Pinter, Tyler B. J.,Stillman, Martin J.

, p. 10747 - 10761 (2013/01/15)

The facile axial ligand exchange properties of gallium(III) protoporphyrin IX in methanol solution were utilized to explore self-association interactions by NMR techniques. Structural changes were observed, as well as competitive behavior with the ligands acetate and fluoride, which differed from that seen with the synthetic analogue gallium(III) octaethylporphyrin which lacks acid groups in its side-chains and has less solution heterogeneity as indicated by absorption and MCD spectroscopies. The propionic acid side chains of protoporphyrin IX are implicated in all such interactions of PPIX, and both dynamic metal-propionic interactions and the formation of propionate-bridged dimers are observed. Fluoride coordination provides an unusual example of slow ligand exchange, and this allows for the identification of a fluoride bridged dimer in solution. An improved synthesis of the chloride and hydroxide complexes of gallium(III) protoporphyrin IX is reported. An insoluble gallium analogue of hematin anhydride is described. In general, the interactions between solvent and the metal are found to confer very high solubility, making [Ga(PPIX)] + a useful model for ferric heme species.

Internal cation mobility in molten CsCl-NdCl3 system at 1073 K

Zab?ocka-Malicka, Monika,Ciechanowski, Bart?omiej,Szczepaniak, W?odzimierz,Gawe?, Wies?aw

, p. 3409 - 3413 (2010/06/21)

CsCl-NdCl3 is the next of binary MCl-NdCl3 systems (M: alkali metal) investigated for determination of relative internal mobilities of cations (bCs, bNd) by countercurrent electromigration method (Klemm's method). The results have been presented as isotherms of internal mobilities of Cs+ and Nd3+ ions on NdCl3 equivalent fraction (yNd). It has been found that internal mobility of cesium cations is higher than neodymium ones in the entire composition range (what is typical for nonsymmetrical MCl-LnCl3 systems (M: Li, Na, K; Ln: La, Nd, Dy)) and decreases with increase of NdCl3 concentration in the melt. Generally, dependence of internal mobility of lanthanide cations in melts with alkali metal chlorides on lanthanide (i.e. its atomic number and concentration) seems strongly related to stability of chloride complex anions of lanthanides in the melt. Investigated systems may be divided into two classes. The first class includes MCl-NdCl3 systems (M: Li, Na) characterized by decrease of bNd with increase of NdCl3 concentration. The second includes KCl-LnCl3 systems (Ln: La, Nd, Dy) and presented here CsCl-NdCl3 system, and is characterized by increase of bLn with concentration of Ln3+ cation. The dependence of bNd on NdCl3 concentration at 1073 K was fitted (as for other systems) by a simple equation of the form: bLn = bLn0 + a (1 - yLnC l3)2, where bLn0 is the internal mobility of Ln3+ cations in pure molten LnCl3, a the difference between internal mobility of Ln3+ cations in pure molten LnCl3 and infinitely diluted LnCl3 in molten alkali metal chloride (extrapolated), and yLnC l3 is the equivalent fraction of LnCl3.
