Most proteins exist in the cell as multi-component assemblies. However, which proteins need to be present simultaneously in order to perform a given function is frequently unknown. The first step toward this goal would be to predict proteins that can function only when in a complexed form. Here, we propose a scheme to distinguish whether the protein components are ordered (stable) or disordered...

Fluorescent derivatives of a phosphatidylglycerol, phosphatidylserine, phosphatidic acid, phosphatidylcholine, phosphatidylethanolamine, and diacylglycerol have been studied to establish the effect of different polar headgroups on the mechanism and kinetics of spontaneous phospholipid transfer between recombinants of human plasma apolipoprotein A-II and dimyristoylphosphatidylcholine. The fluor...

Adsorption of polar monomers on ice surface, relevant to the physical/chemical reaction in ice clouds as well as growth of ice, remains an open issue partially due to the unusual surface characteristics with protons at the top layer of ice. Using first-principle calculations, we explore the adsorption properties of ice surface in terms of a surface proton order parameter, which characterizes th...

In typical cyclic polymer synthesis via ring-closure, chain growth and cyclization events are competing with each other, thus affording polymers uncontrolled molecular weight or ring size high dispersity. Here we uncover a mechanism by which Lewis pair polymerization (LPP) operates on polar vinyl monomers that allows the control of where when takes place, thereby achieving spatial temporal to a...

Abstract Herein an efficient approach to produce functional polypropylene via solvent assisted solid-phase grafting process is reported, in which acrylic acid, methyl methacrylate and maleic anhydride are used as multi-monomers, 2,2?-azobis(2-methylpropionitrile) initiator ether swelling carrier. The effects of various factors such the species dosage, time temperature, monomer concentrations, r...

Infrared combination bands of the polar isomer N2O dimer are observed for first time, using a tunable infrared laser source to probe pulsed slit-jet supersonic expansion in nu1 region (~2240 cm-1). One band involves torsional (out-of-plane) intermolecular mode and yields frequency 19.83 cm-1 if associated with out-of-phase fundamental (N2O nu1) vibration monomers dimer. The other band, which is...

In this research paper, we present a novel frame work for handling $m$-polar information by combining the theory of $m-$polar fuzzy  sets with graphs. We introduce certain types of edge regular $m-$polar fuzzy graphs and edge irregular $m-$polar fuzzy graphs. We describe some useful properties of edge regular, strongly edge irregular and strongly edge totally irregular $m-$polar fuzzy graphs. W...
