Gold Nanofilms at Liquid–Liquid Interfaces: An Emerging Platform for Redox Electrocatalysis, Nanoplasmonic Sensors, and Electrovariable Optics

Pekka Eero Peljo, Micheal Diarmaid Scanlon, Evgeny Smirnov, Thomas James Stockmann

The functionality of liquid–liquid interfaces formed between two immiscible electrolyte solutions (ITIES) can be markedly enhanced by modification with supramolecular assemblies or solid nanomaterials. The focus of this Review is recent progress involving ...

Colloidal nanocrystals for photoelectrochemical and photocatalytic water splitting

Raffaella Buonsanti, Anna Loiudice, Chethana Janardhana Gadiyar

Colloidal nanocrystals (NCs) are among the most modular and versatile nanomaterial platforms for studying emerging phenomena in different fields thanks to their superb compositional and morphological tunability. A promising, yet challenging, application in ...

Biocompatible Amphiphilic Hydrogel–Solid Dimer Particles as Colloidal Surfactants

Esther Amstad, Jing Fan

Emulsions of two immiscible liquids can slowly coalesce over time when stabilized by surfactant molecules. Pickering emulsions stabilized by colloidal particles can be much more stable. Here, we fabricate biocompatible amphiphilic dimer particles using a h ...

Cellulose Nanocrystals with Tethered Polymer Chains: Chemically Patchy versus Uniform Decoration

Harm-Anton Klok, Alke Fink, Justin Orazio Zoppe, Théo Gaston Gérard Lachat, Alix Vaimiti Marie Dupire

The site-specific surface modification of colloidal substrates, yielding "patchy" nanoparticles, is a rapidly expanding area of research as a result of the new complex structural hierarchies that are becoming accessible to chemists and materials scientists ...

Recent Developments in Accelerated Antibacterial Inactivation on 2D Cu-Titania Surfaces under Indoor Visible Light

César Pulgarin, Juan Kiwi, Sami Rtimi

This review focuses on Cu/TiO2 sequentially sputtered and Cu-TiO2 co-sputtered catalytic/photocatalytic surfaces that lead to bacterial inactivation, discussing their stability, synthesis, adhesion, and antibacterial kinetics. The intervention of TiO2, Cu, ...

Top-down design of magnonic crystals from bottom-up magnetic nanoparticles through protein arrays

Dirk Grundler

We show that chemical fixation enables top-down micro-machining of large periodic 3D arrays of protein-encapsulated magnetic nanoparticles (NPs) without loss of order. We machined 3D micro-cubes containing a superlattice of NPs by means of focused ion beam ...

High-Throughput Step Emulsification for the Production of Functional Materials Using a Glass Microfluidic Device

Esther Amstad

High-volume production of monodisperse droplets is of importance for industrial applications due to increased emulsion stability, precise control over droplet volumes, and the formation of periodic arranged structures. So far, parallelized microfluidic dev ...
