The physicochemical properties of solute in solutions provide valuable information on solute –solvent, solute – solute and solvent – solvent interactions. The intermolecular forces between theliquids molecules and solvent molecules affect the viscosity of the solution. Information regardinginter and intra molecular interactions can be obtained from volumetric, and viscometric data in asolute so...

in ziegler-natta olefin polymerization, the pore architecture of catalysts plays a crucial role in catalyticperformances and polymer properties. while the type of preparation routes (such as chemical reaction andsolution precipitation) greatly affects the catalyst pore architecture as a result of different solidification mechanisms,the modification of the pore architecture within a given route ...

A method for predicting the solidification and stress of a digital light processing 3D print process is presented, using voxel-based, multi-layer model to predict degree polymerization material at every stage during print.

Actin polymerization has been shown to be sufficient to propel curved objects, for example beads and vesicles coated with the Listeria monocytogenes protein ActA. Recent studies suggest that actin polymerization on flat surfaces can also provide the propulsive force to push them forward.

Monomers in the polymer-based provisional crown and fixed partial denture materials form polymer network as carbon-carbon double bonds are converted to carbon-carbon single bonds during polymerization. This reaction is not complete. There will be a certain amount of monomer remaining in the resin materials. This is influenced by several factors, such as type of monomer, curing temperature, expo...

A polystyrene-b-poly(methylmethacrylate) (PS-b-PMMA) modified with a fluorine-containing functional group at its chemical junction was designed to study the effect of on microphase separation behavior. Various molecular weights and unmodified PS-b-PMMA were synthesized, effective χ parameter for them estimated by small-angle X-ray scattering. The clearly observed in measured parameters block co...

Procyanidins, commonly found in plant natural sources, are polymerized forms of flavanols, which a subclass flavonoids. They have been reported to exhibit broad benefits human health and used the prevention cancers, cardiovascular diseases, diabetes, etc. Bioactivities procyanidins depend on many factors including structures procyanidins. Differences composition monomers degree polymerization (...
