Low polydispersity poly(N-isopropylacrylamide) with a biotin end-group was obtained in one step from a biotinylated initiator for atom transfer radical polymerization and interacted with streptavidin to generate the thermosensitive polymer-protein conjugate.

in current work a comprehensive mechanism based on intermediate radical termination theory is assumed for raft polymerization of styrene over cumyl dithiobenzoate as raft agent. rate constants for addition (ka) and fragmentation reactions (kf) are set to 6×106 and 5×104 respectively, which lead to an equilibrium constant value of k = ka/kf = 1.2 x 102. moment equations method was used to model ...

We numerically study the dynamics of a polydisperse double emulsion under symmetric shear flow. show that both dispersity and rate crucially affect behavior innermost drops surrounding shell. While at low/moderate values rates inner rotate periodically around common center mass triggered by fluid vortex formed within generally regardless their polydispersity, higher such occurs only increasing ...

State-of-the-art techniques for simulating deeply supercooled liquids require a high degree of size polydispersity to be effective. While these have enabled great insight into the microscopic dynamics near glass transition, effect large on has remained largely unstudied. Here we show that particle's not only strong correlation with its mobility, but also observe that, as mode-coupling temperatu...

Polymers are large molecules consisting of a large number of small component molecules chemically linked together. They are made from constituent monomers through polymerization process. Polymers are unique materials in that they consist of a statistical distribution of chains of varying lengths, and each chain consists of monomer residues which affect its properties hence they require several ...

The size distribution and protein composition of casein micelles in the milk of Holstein-Friesian cows was determined as a function of stage and number of lactations. Protein composition did not vary significantly between the milks of different cows or as a function of lactation stage. Differences in the size and polydispersity of the casein micelles were observed between the milks of different...

The polymerization of isoprene through the use of benzyl N,N-diethyldithiocarbamate (BDC) as an iniferter was investigated. The monomer concentration used was kept constant at 2.8 mol/L while the BDC concentration was varied. The polymer product was characterized by Fourier Transform Infrared Spectroscopy (FTIR), Proton Magnetic Resonance (H-NMR), and Differential Scanning Calorimetry (DSC) and...

As the most abundant aromatic compounds, lignin is still underutilized due to its relatively low quality. In order to improve its quality, two pretreatment technologies, wet ball milling (WBM) and ionic liquid pretreatment (ILP) were tested on the industrial lignin and evaluated on the average molecular weight and polydispersity, surface morphology, and functional groups changes. The results sh...
