Mechanism of the Cassie-Wenzel transition via the atomistic and continuum string methods

The string method is a general and flexible strategy to compute the most probable transition path for an activated process (rare event). We apply here the atomistic string method in the density field to the Cassie-Wenzel transition, a central problem in th ...

Contact angle and adsorption energies of nanoparticles at the air-liquid interface determined by neutron reflectivity and molecular dynamics

Francesco Stellacci, Javier Reguera Gomez, Mauro Moglianetti, Evgeniy Ponomarev

Understanding how nanomaterials interact with interfaces is essential to control their self-assembly as well as their optical, electronic, and catalytic properties. We present here an experimental approach based on neutron reflectivity (NR) that allows the ...

Copolymerization of 2,2,3,3,4,4,4-heptafluorobutyl acrylate with butyl acrylate via RAFT polymerization

Harm-Anton Klok

Copolymers of fluoroacrylates have interesting properties like excellent resistance to chemicals, oils and fuels, high thermal stability and high hydrophobicity. This investigation reports the copolymerization of 2,2,3,3,4,4,4-heptafluorobutyl acrylate (HF ...

Self-Assembly of a Giant Molecular Solomon Link from 30 Subcomponents

Kay Severin, Rosario Scopelliti, Clément Schouwey, Yury Tsybin, Konstantin Zhurov, Konstantin Nagornov

The synthesis of topologically complex structures, such as links and knots, is one of the current challenges in supramolecular chemistry. The so-called Solomon link consists of two doubly interlocked rings. Despite being a rather simple link from a topolog ...

On-Chip Fabrication of Paclitaxel-Loaded Chitosan Nanoparticles for Cancer Therapeutics

Philippe Renaud, Arnaud Bertsch, Fatemeh Sadat Majedi, Mohammad Mahdi Hasani-Sadrabadi, Shahin Bonakdar, Jules John Vandersarl

The use of solvent-free microfluidics to fine-tune the physical and chemical properties of chitosan nanoparticles for drug delivery is demonstrated. Nanoparticle self-assembly is driven by pH changes in a water environment, which increases biocompatibility ...

Fluid-mediated parallel self-assembly of polymeric micro-capsules for liquid encapsulation and release

Alcherio Martinoli, Jürgen Brugger, Grégory Mermoud, Loïc Jacot-Descombes, Luis Guillermo Villanueva Torrijo, Cristina Martin Olmos, Victor Javier Cadarso Busto, Rosario Maurizio Gullo, Massimo Mastrangeli

Fluid-mediated self-assembly is one of the most promising routes for assembling and packaging smart microsystems in a scalable and cost-efficient way. In this work the pairwise fluidic self-assembly of 100 μm-sized SU-8 cylinders is studied with respect to ...

Formation and Properties of Self-Assembly-Driven Fluorescent Nanoparticle Sensors

Paul Joseph Dyson, Zhaofu Fei

Fluorescent nanoparticles (FNPs) are obtained in water by self-assembly from a polymeric ionic liquid, fluorescent carboxylate moiety, and a surfactant through two main supramolecular interactions, that is, ionic bonds and hydrophobic/hydrophilic interacti ...

A Self-Organized Anisotropic Liquid-Crystal Plasmonic Metamaterial

Toralf Scharf, Feng Liu

A composite material that leads to self organization of mesogen-coated gold nanospheres is synthesized and shows enhanced anisotropic optical properties due to synergistic effects of the mesogens intrinsic birefringence and its ability to drive the self-as ...

Characterization of Hydrophobic Forces for in Liquid Self-Assembly of Micron-Sized Functional Building Blocks

Laure Aeschimann, Jürgen Brugger, Loïc Jacot-Descombes, Rosario Maurizio Gullo

This paper presents the experimental and numerical study of hydrophobic interaction forces at nanometer scale in the scope of engineering micron-sized building blocks for self-assembly in liquid. The hydrophobic force distance relation of carbon, Teflon an ...

Fabrication of Functional Silicon Surfaces using Metallic Nanostructures Produced by Block Copolymer Self-Assembly

Li Wang

Self-assembly is the autonomous organization of components into patterns or structures without human intervention. At the molecular level, self-assembly usually involves non-covalent interactions of various natures, such as van der Waals, electrostatic and ...
