Search for Non-Protein Protease Inhibitors Constituted with an Indole and Acetylene Core

open access: yesMolecules, 2021
A possible inhibitor of proteases, which contains an indole core and an aromatic polar acetylene, was designed and synthesized. This indole derivative has a molecular architecture kindred to biologically relevant species and was obtained through five ...

Ordered smectic phase formed by novel binary liquid crystalline systems consisting of low-molecular-weight polar compounds and an amorphous side-chain polymer

open access: yesStudies in Science and Technology, 2023
Novel binary liquid crystalline systems were obtained by mixing amorphous side-chain polymethacrylate (SCP) and polar compounds. Their thermal and orientational properties were examined by DSC measurement, polarizing microscopy and temperature-variable X-

Integral Inequalities for the Polar derivative and the generalized Polar derivative of complex Polynomials

open access: yesUniversity of Aden Journal of Natural and Applied Sciences, 2023
For a polynomial P(z) of degree n , having all zeros in |z|≤1, Malik [11] proved that for each q>0, \(n [∫_0^{2π} |P(e^{iθ})|^q dθ] ^{1⁄q} ≤[∫_0^{2π} | 1 + e^{iθ} |^q dθ]^{1⁄q} \underset{|z|=1}{max} |P^ʹ (z)|\). In this paper we generalize the above inequality to polar derivative and generalized polar derivative, which as special cases include ...

Estimates for the polar derivative of a constrained polynomial on a disk

open access: yesCubo, 2022
This work is a part of a recent wave of studies on inequalities which relate the uniform-norm of a univariate complex coefficient polynomial to its derivative on the unit disk in the plane.

Gas-liquid chromatographic analyses of 1,2-ethanediol monoethers and monoesters

open access: yesJournal of Lipid Research, 1968
Synthetic mixtures of saturated and unsaturated monoethers and monoesters of 1,2-ethanediol, ranging in chain length from 12 to 20, were analyzed as acetates, trifluoroacetates (TFA), and trimethylsilyl (TMS) ethers by gas chromatography on polar and ...

Spectroscopic Probe of the van der Waals Interaction between Polar Molecules and a Curved Surface [PDF]

open access: yes, 2016
We study the shift of rotational levels of a diatomic polar molecule due to its van der Waals (vdW) interaction with a gently curved dielectric surface at temperature $T$, and submicron separations.
