The investigation provides a study on the thermophysical properties of 3-methyl-1-butanol with medium-chain alcohols (1-pentanol to 1-octanol) within the temperatures 293.15 K to 333.15 K. Findings indicate positive excess molar volumes that escalate with the lengthening of the carbon chain in the...
The ES-MS spectra were recorded on an ion trap LCQ Advantage Max mass spectrometer (Thermo Electron Corporation)33. The melting point apparatus (Stuart SMP10) was used to determine the melting points of the synthesized compounds34. Fourier transform infrared spectroscopy (FTIR) analysis was carried...
The center of mass and the relevant site-site pair correlation functions, self-diffusion coefficients, and thermodynamic properties of the molecular system were calculated and analyzed. At low densities we found the nearest configuration to be maximal 1 argon with a nearly T-shaped (1:1) ...
(1) where mi is the mass of the i-th atom, ri are the spatial coordinates of the i-th atom, t is time, Fi is the force acting on the i-th atom, and U(r) is the potential energy (that is, the force field), which is a function of the coordinates of all at...
We use SCFBio (http://www.scfbio-iitd.res.in/software/drugdesign/lipinski.jsp) web tool for evaluating their Lipinski rule satisfaction of drug likeness properties (including molecular weight, number of hydrogen donor and acceptor bonds, rotatable bond, octanol/water partition coefficient or LogP...

All eigenvalues of the Hessian are positive for minima while transition states have one negative eigenvalue. The eigenvector corresponding to the negative eigenvalue describes the transition mode. Following the minimum energy path in mass-weighted coordinates (intrinsic reaction coordinate, IRC) allows ...
85 vol% of the non-aqueous mass of SC; still, they are less well characterized than the lipid fraction. Corneocytes are anucleated dead cells that are filled with keratin and wrapped by a cornified protein envelope [71] that is covered with a monolayer of lipids (mainly ceramides) [42]...
