Direct Observation of the Phase Transition in C60 Fullerene

In the third study, the order-disorder phase transition of single-crystal C60 is studied using time-resolved electron microscopy. Solid C60 undergoes a first-order phase transition upon heating to 260 K. This is a structural transition from the low-tempera ...

Influence of Sphericity on Surface Termination of Icosahedral Colloidal Clusters

Esther Amstad

Colloids self-organize into icosahedral clusters composed of a Mackay core and an anti-Mackay shell under spherical confinement to minimize the free energy. This study explores the variation of surface arrangements of colloids in icosahedral clusters, focu ...

In Situ and Time-Resolved Transmission Electron Microscopy of Nanoscale Processes

Chengcheng Yan

Observing the fast dynamics of nanoscale systems is crucial in order to understand and ultimately control their behavior. Characterizing these dynamic processes requires techniques with atomic spatial resolution and a temporal resolution that matches the t ...

Reactivity of Bromine Radical with Dissolved Organic Matter Moieties and Monochloramine: Effect on Bromate Formation during Ozonation

Urs von Gunten, Sung Eun Lim

Bromine radical (Br center dot) has been hypothesized to be a key intermediate of bromate formation during ozonation. Once formed, Br center dot further reacts with ozone to eventually form bromate. However, this reaction competes with the reaction of Br c ...

Fabrication of ZIF-8 membranes by direct assembly of nanosheets from bottom-up synthesis growth solution

Kumar Varoon Agrawal, Xuekui Duan, Heng-Yu Chi

Metal-organic frameworks (MOFs) host intrinsically porous structure and rich structural and chemical features. Several MOFs with pore aperture comparable to the size of gas molecules have attracted interest to form the selective layer of membranes. Synthes ...

Viscoelastic surface electrode arrays to interface with viscoelastic tissues

Stéphanie Lacour, Alix Esther Anne Trouillet, Nicolas Vachicouras, Florian Dylan Fallegger, Christina Myra Tringides

Bioelectronic interfacing with living tissues should match the biomechanical properties of biological materials to reduce damage to the tissues. Here, the authors present a fully viscoelastic microelectrode array composed of an alginate matrix and carbon-b ...

Subphthalocyanine-based electron-transport materials for perovskite solar cells

Mohammad Khaja Nazeeruddin, Hiroyuki Kanda, Nadja Isabelle Desiree Klipfel

Non-fullerene ETMs are emerging as a hot topic in the field of PSCs due to the inherent shortcomings of fullerene derivatives. Herein, the potential of SubPcs as ETMs in PSCs has been evaluated. To this end, ETMs based on two SubPcs (with chlorine or fluor ...

Propulsion and energetics of a minimal magnetic microswimmer

Ignacio Pagonabarraga Mora

In this manuscript we describe the realization of a minimal hybrid microswimmer, composed of a ferromagnetic nanorod and a paramagnetic microsphere. The unbounded pair is propelled in water upon application of a swinging magnetic field that induces a perio ...

Single Photon Emission from a Plasmonic Light Source Driven by a Local Field-Induced Coulomb Blockade

Klaus Kern, Anna Maria Roslawska, Abhishek Grewal

A hallmark of quantum control is the ability to manipulate quantum emission at the nanoscale. Through scanning tunneling microscopy-induced luminescence (STML), we are able to generate plasmonic light originating from inelastic tunneling processes that occ ...

Hexayne Amphiphiles and Bolaamphiphiles

Rosario Scopelliti, Holger Frauenrath, Enzo Jean Raymond Bomal, Reuben Yeo Jueyuan, Vincent Matthieu Guillaume Croué

Oligoynes with two or more conjugated carbon-carbon triple bonds are useful precursors for carbon-rich nanomaterials. However, their range of app0lications has so far been severly limited by the challenging syntheses, particularly in the case of oligoynes ...
