Pyrrolic‐Nitrogen‐Enriched Aerogels With Magnetic Responsiveness Enable Cooperative Hydrogen‐Bond Regulation for High‐Performance Solar Interfacial Evaporation

open access: yesCarbon Energy, EarlyView.
A pyrrolic‐nitrogen‐enriched ferromagnetic aerogel enables sophisticated cooperative regulation of hydrogen bonding, whereby this dual‐regulatory mechanism effectively reduces vaporization enthalpy while simultaneously enhancing molecular dynamics. The system demonstrates exceptional self‐cleaning capability and exhibits superior performance in the ...

Copper(II), a Peculiar Metal Ion for Complexation with Monensin A Ionophore

open access: yesChemistry – A European Journal, EarlyView.
Copper(II) forms three chiral and EPR‐active complexes with monensinate A in methanol. Beside the bis [CuL2] and mono [CuL]+ species, the new dinuclear construct [Cu2L]3+ exhibits an [ML]+‐type and a metal salt‐type copper(II) centers weakly bound to each other through counter ion(s) and thus, being magnetically independent.

Resolving a Nearly Two‐Centuries‐Old Mystery: On the Structural Chemistry and Physicochemical Properties of Compounds Associated With the Term Ammelide

open access: yesChemistry – A European Journal, EarlyView.
The crystal structure of ammelide, also known as melanuric acid, was solved almost 200 years after its discovery by Liebig. Moreover, three modifications of its 1:1 adduct with ammeline were structurally elucidated, consisting of layers with a honeycomb motif analogous to melamine cyanurate.

Kummer’s conjecture for cubic Gauss sums [PDF]

open access: yesIsrael Journal of Mathematics, 2000
In J. Reine Angew. Math. 310, 111--130 (1979; Zbl 0412.10028) the author and the reviewer proved that cubic Gauss sums defined over primes in the ring \(\mathbb Z[\omega]\), \(\omega^2+ \omega+1=0\) were uniformly distributed; this result showed in particular that conjecture (or rather suggestion) about the distribution of the values of cubic Gauss ...

The expansion of a finite number of terms of the Gauss hypergeometric function of unit argument and the Landau constants [PDF]

open access: yes, 2014
We obtain convergent inverse factorial expansions for the sum Sn(a, b; c) of the first n ≥ 1 terms of the Gauss hypergeometric function 2F1(a, b; c; 1) of unit argument. The form of these expansions depends on the location of the parametric excess s := c−

WSPLK: A systematic approach to the thermodynamic characterization of light and heavy Mexican crude oil

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract A streamlined characterization framework (WSPLK) is presented for modelling complex reservoir fluids using cubic equations of state. The key methodological contribution is the introduction of a single global parameter ε directly into Pedersen's boiling‐point correlation, restoring pure‐component calibration and eliminating the need for ...

Fast Approximation of Algebraic and Logarithmic Hypersingular Type Singular Integrals with Highly Oscillatory Kernel

open access: yesInternational Journal of Analysis and Applications, 2020
Herein, highly oscillatory integrals with hypersingular type singularities are studied. After transforming the original integral into a sum of line integrals over a positive semi-infinite interval, a Gauss-related quadrature rule is constructed.

Playing with fire? A mean‐field game analysis of fire sales and systemic risk under regulatory capital constraints

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We analyze the effect of regulatory capital constraints on financial stability in a large homogeneous banking system using a mean‐field game (MFG) model. Each bank holds cash and a tradable risky asset. Banks choose absolutely continuous trading rates in order to maximize expected terminal equity, with trades subject to transaction costs ...
