A reversible crystal to crystal structural transformation of lead(II) complex; [Pb(OH2)2(Phe)2(NO3)]n[NO3] (1), (Phe:L-phenylalanine), to coordination polymer 2D [Pb(phe)2]n (2); has been observed upon solid–gas and solid–solid reactions of compound 1 to compound 2 and then 2...
Transparency (T) was calculated using the following formula: $${{\rm{T}}}=\frac{{C}_{{brain}}}{{C}_{{background}}}$$ (3) In the abovementioned Eq. (3), Cbrain indicates the C of regions beneath the cleared brain tissue, whereas Cbackground indicates the C of background ...
Crystals: these have long range ordering which could lead to a single crystal if the ordering is consistent throughout the solid material. In general, no solid or liquid is completely structureless. Ionic solids do not form glasses but covalent solids form glasses (e.g. polymers) e.g. MgO ...
19 The maximum in the (solid + liquid) equilibrium curve at x2 = 0.5 results from the formation of a solid addition compound with the formula CCl4· 1,4-C6H4(CH3)2 that melts at the temperature corresponding to the maximum, to form a liquid with the same composition. This type of ...
Experimental and predicted 207Pb nuclear magnetic resonance (NMR) parameters of solid-state coordination complexes of lead(II) bromide, lead(II) iodide, and lead(II) chloride with 1,10-phenanthroline are reported. Structural and electronic differences between the 1:1 and 1:2 adducts are reflected...
The penetration depth of microwaves is also calculated with effective complex permittivity by the following formula23: $$D_{p} = \frac{{\lambda_{0} }}{{2\pi \sqrt {\left( {2\varepsilon_{r,eff}^{^{\prime}} } \right)} }}\frac{1}{{\sqrt {\left( {\sqrt {1 + \left( {\...

Present simple formulae in line with normal text, where possible. Use the solidus (/) instead of a horizontal line for small fractional terms such as X/Y. Present variables in italics. Denote powers of e by exp. Display equations separately from your text, numbering them consecutively in the...
Considering that the bulk exhibits 0.33 Li per unit cell (unless otherwise specified, the “unit cell” in this work refers to the prototype perovskite unit cell with one ABX3 formula unit), the maximum number of Li per unit cell in the SCL region should be around 0.66; that is, the ...
(ΔEτ) were shown in Supplementary Fig.6a, representing an elimination of chemical composition inhomogeneity via Li+diffusion droved by the electrochemical polarization and concentration polarization. Based on the formula\(D_{Li^ + } = \frac{4}{{\pi \tau }}\left( {\frac{{m_BV_M}}{{...
