Non equilibrium thermodynamics of protein organization

Three quarters of the thesis will be devoted to the discussion of non equilibrium systems. We show how certain biological systems cannot be described by standard thermodynamics. The reason is that the energy consumption due to the hydrolysis of ATP imposes ...

Rapid, Selective Heavy Metal Removal from Water by a Metal-Organic Framework/Polydopamine Composite

Emad Oveisi, Wendy Lee Queen, Seyedmohamad Moosavi, Daniel Teav Sun, Li Peng, Davide Tiana

Drinking water contamination with heavy metals, particularly lead, is a persistent problem worldwide with grave public health consequences. Existing purification methods often cannot address this problem quickly and economically. Here we report a cheap, wa ...

Size limitations on achieving tough and healable fibre reinforced composites through the use of thermoplastic nanofibres

Véronique Michaud, Amaël Maximilien Cohades

Phase-separated blends of epoxy and poly(ε-caprolactone) (PCL) provide crack repair in composites after a thermal treatment at 150 °C, but decrease the material’s fracture toughness. This article investigates the combination of healing with interlaminar fr ...

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 ...

Beyond the Hofmeister Series: Ion-Specific Effects on Proteins and Their Biological Functions

Halil Ibrahim Okur

Ions differ in their ability to salt out proteins from solution as expressed in the lyotropic or Hofmeister series of cations and anions. Since its first formulation in 1888, this series has been invoked in a plethora of effects, going beyond the original ...

Molecular Strategies for Morphology Control in Semiconducting Polymers for Optoelectronics

Kevin Sivula, Muhammad Aiman Bin Rahmanudin Hamdan

Solution-processable semiconducting polymers have been explored over the last decades for their potential applications in inexpensively fabricated transistors, diodes and photovoltaic cells. However, a remaining challenge in the field is to control the sol ...

Effect of Very High Charge Density and Monomer Constitution on the Synthesis and Properties of Cationic Polyelectrolytes

Jutta Christine Wandrey, Hamideh Ahmadloo

The free-radical homopolymerization of 1,3-bis(N,N,N-trimethylammonium)-2-propylmethacrylate dichloride (di-M) and 1,3-bis(N,N,N-trimethylammonium)-2-propylacrylate dichloride (di-A) in aqueous solution yields cationic polyelectrolytes (PEL) with theoretic ...

Influence of Block versus Random Monomer Distribution on the Cellular Uptake of Hydrophilic Copolymers

Harm-Anton Klok, John Moraes, Raoul Peltier

The use of polymers has revolutionized the field of drug delivery in the past two decades. Properties such as polymer size, charge, hydrophilicity, or branching have all been shown to play an important role in the cellular internalization of polymeric syst ...

Degrafting of Poly(poly(ethylene glycol) methacrylate) Brushes from Planar and Spherical Silicon Substrates

Harm-Anton Klok, Nariye Cavusoglu Ataman

Densely grafted, hydrophilic polymer brushes produced via surface-initiated controlled radical polymerization have been shown to undergo degrafting upon exposure to aqueous media. This degrafting process has been proposed to involve swelling-induced, mecha ...
