Thermochemistry of N-heterocyclic carbenes with 5-, 4-, 3-, and 2-membered rings
(Wiley, 2014)
N-heterocyclic carbenes (NHCs) based on imidazole-2-ylidene (1) or the saturated imidazolidine-2-ylidene (2) scaffolds are long-lived singlet carbenes. Both benefit from inductive stabilization of the sigma lone pair on ...
Automorphisms of aut(A),A a free abelian group
(Taylor & Francis, 2015)
We prove that all automorphisms of the automorphism group of an infinitely generated free abelian group are inner.
Calculation of the soft-mode frequency for the alpha – beta transition in quartz
(Elsevier, 2016)
The ? – ß structural transition occurs in quartz at TC = 846 K. The frequency of the soft mode associated with the volume increase, decreases with increasing temperature as the transition temperature is approached. In this ...
On the outer automorphism groups of free groups
(Elsevier, 2014)
We prove that the outer automorphism group of a free group of countably infinite rank is complete.
Calculation of the Raman frequency shifts for the ? phase of solid oxygen
(Elsevier, 2017)
We calculate in this study the Raman frequencies of the two librons and one vibron at various pressures at constant temperatures of 10 K and also at the temperatures of 6 and 18 K by using the volume data from the literature ...
Pressure effect on the cholesteric – smectic A transition in cholestryl myristate
(Taylor & Francis, 2016)
Cholesteryl myristate exhibits tricritical behavior under high pressures close to its cholesteric-smectic A (Ch/SA) transition, as observed experimentally. We study here the thermodynamic properties of this liquid crystal ...
Temperature effect on the structural ferroelectric – paraelectric transition in Li2Ge7O15
(Taylor & Francis, 2016)
Li2Ge7O15 (LGO) undergoes the ferroelectric – paraelectric transition at Tc D283.5K. The crystal structure of LGO is orthorhombic with the four formula units in the unit cell in the paraelectric phase (T < TC) . The ...
Phase-dependent interference fringes in the wavelenght scaling of harmonic efficiency
(American Physical Society, 2014)
We describe phase-dependent wavelength scaling of high-order harmonic generation efficiency driven by ultra-short laser fields in the mid-infrared. We employ both numerical solution of the time-dependent Schr¨odinger ...
Variation of the molar volume with the temperature and the Pippard relations near the melting point in benzene
(Elsevier, 2016)
In this study, we calculate variation of the molar volume with the temperature at constant pressures (70.5, 85.2, 128 and 175.2 MPa) using the experimental data from the literature for the solid and liquid phases of benzene ...
A note on the order bidual of f-algebras
(Hikari, 2013)
The paper deals with the Arens Multiplication which we accomplished in four steps in the order bidual ~ ~ X . It is shown that if f is an element of order dual ~ X of X with ? ( f )?0 and , + x ? X then f .x = 0 implies f (x)= .
