Surface-Initiated Controlled Radical Polymerization: State-of-the-Art, Opportunities, and Challenges in Surface and Interface Engineering with Polymer Brushes

Harm-Anton Klok, Jian Wang, Piotr Mocny, John Moraes, Nariye Cavusoglu Ataman

The generation of polymer brushes by surface-initiated controlled radical polymerization (SI-CRP) techniques has become a powerful approach to tailor the chemical and physical properties of interfaces and has given rise to great advances in surface and int ...

The Shape of a Stretched Polymer

Paolo De Los Rios, Salvatore Assenza, Alberto Stefano Sassi

The shape of a polymer plays an important role in determining its interactions with other molecules and with the environment, and is in turn affected by both of them. As a consequence, in the literature the shape properties of a chain in many different con ...

FlyLimbTracker: An Active Contour Based Approach for Leg Segment Tracking in Unmarked, Freely Behaving Drosophila

Michaël Unser, Ricard Delgado Gonzalo, Virginie Sophie Uhlmann

Understanding the biological underpinnings of movement and action requires the development of tools for quantitative measurements of animal behavior. Drosophila melanogaster provides an ideal model for developing such tools: the fly has unparalleled geneti ...

Fabrication of slender elastic shells by the coating of curved surfaces

François Gallaire, Pedro Miguel Nunes Pereira de Almeida Reis, Gioele Mariano Nicolò Balestra, Pierre-Thomas Paul Brun

Various manufacturing techniques exist to produce double-curvature shells, including injection, rotational and blow molding, as well as dip coating. However, these industrial processes are typically geared for mass production and are not directly applicabl ...

Toward an Effective Control of DNA's Submolecular Conformation on a Surface

Giovanni Dietler, Aleksandre Japaridze, Dusan Vobornik, Andrea Cerreta, Ewelina Wioletta Lipiec

DNA adopts different conformations based on its environment. We reveal conditions that either preserve the DNA's physiological B-conformation, even upon its placement in UHV, or lead to a partial B-form to A-form reorganization upon DNA's deposition on a s ...

Enhanced permeation arising from dual transport pathways in hybrid polymer-MOF membranes

Wendy Lee Queen, Daniel Teav Sun

The rise of anthropogenic global warming has sparked new interest in developing strategies to mitigate carbon dioxide emissions. Conventional carbon capture processes are not economically viable at scale due to their enormous energy cost. Membrane-based se ...

Damping Materials from Hierarchically Structured Oligopeptide-Modified Polymer Blends

Su Liang

Certain natural materials such as bones not only show high stiffness and high damping performance but also exhibit other superior properties as the result of complex hierarchical structure formation. Synthetic polymer materials have demonstrated a great ve ...

Light absorption in 1D and 2D nanostructured organic semiconductors

Damien Rolland

Organic photovoltaics will be one of the corner stones in solving the increasing world's energy demand issue. For this reason, a better understanding of the detailed mechanisms involved in energy conversion in the employed nanostructured materials is still ...

Stress reduction mechanisms during photopolymerization of functionally graded polymer nanocomposite coatings

Jan-Anders Edvin Maansson, Véronique Michaud, Yves Leterrier, Tommaso Nardi, Florian Dujonc

From the experimental analysis of the photocuring process in terms of reaction kinetics as well as modulus and shrinkage build-up, the residual stresses arising during the photopolymerization of functionally graded composite coatings based on an acrylate m ...

A Close Look at Charge Generation in Polymer:Fullerene Blends with Microstructure Control

Jacques-Edouard Moser, Natalie Renuka Banerji, Mariateresa Scarongella, Jelissa Risse, Natalie Stingelin

We reveal some of the key mechanisms during charge generation in polymer:fullerene blends exploiting our well-defined understanding of the microstructures obtained in pBTTT:PCBM systems via processing with fatty acid methyl ester additives. Based on ultraf ...

Structure and rheology of star polymers in confined geometries: a mesoscopic simulation study

Dominic John Tildesley

Mesoscopic simulations of star polymer melts adsorbed onto solid surfaces are performed using the dissipative particle dynamics (DPD) method. A set of parameters is developed to study the low functionality star polymers under shear. The use of a new bond-a ...
