The Influence of Irradiation Wavelength on the Growth of Polymer Brushes by SI‐PET‐RAFT Polymerization

open access: yesJournal of Polymer Science, EarlyView.
The use of SI‐PET‐RAFT has been gaining momentum for producing thick, homogenous, functional polymer brushes, in an oxygen‐tolerant manner. However, the connection between irradiation wavelength and the brush height has not been clear. Herein, we systematically explore the effect of irradiation wavelength on the resulting brush properties, finding a ...

Hybrid Nanoparticles Separated by Buoyant Density in a Large‐Scale Centrifugal Process

open access: yesJournal of Polymer Science, EarlyView.
Zonal rotors, shaped like hollow bowls, can sort mixtures of macromolecules and polymer nanoparticles based only on their densities, regardless of their actual sizes or shapes. Using these rotors can make a big difference because they do not need to use centrifuge tubes.

Dynamic Characteristics of Redox‐ and Thermoresponsive Hydrogel Films on the Nanometer Scale to Compensate Structure Defects

open access: yesJournal of Polymer Science, EarlyView.
Dually responsive nanogel‐films have undergone temperature‐ and redox‐cycles. These have shown that synthetic stress has to be released before predictive behaviour can be reached. ABSTRACT The responsiveness of hydrogel films is influenced by network defects, particularly at the surface.

Uniaxial Molecular Alignment in Thin Films Composed of Discrete NDI‐T2 Oligomers Investigated by Variable‐Angle Spectroscopic and Imaging Ellipsometry

open access: yesphysica status solidi (b), EarlyView.
Uniaxially anisotropic optical models are used to analyze spectroscopic ellipsometry data of thin films of discrete oligomers consisting of alternating units of naphthalene diimide (NDI) and bithiophene (T2). They point to a possible preferred molecular orientation parallel to the substrate surface in thermally crystallized films.

RELIABLE COGNITIVE DIMENSIONAL DOCUMENT RANKING BY WEIGHTED STANDARD CAUCHY DISTRIBUTION

open access: yesICTACT Journal on Soft Computing, 2017
Categorization of cognitively uniform and consistent documents such as University question papers are in demand by e-learners. Literature indicates that Standard Cauchy distribution and the derived values are extensively used for checking uniformity and ...
