Non-equilibrium kinetics and trajectory thermodynamics of synthetic molecular pumps

Cristian Pezzato

A major goal in the design of synthetic molecular machines is the creation of pumps that can use the input of energy to transport material from a reservoir at low chemical potential to a different reservoir at higher chemical potential, thereby forming and ...

The process of Lewy body formation, rather than simply α-synuclein fibrillization, is one of the major drivers of neurodegeneration

Hilal Lashuel, Graham Knott, Marion Leleu, Fabien Kuttler, Anne-Laure Mahul Mellier, Mary-Claude Croisier-Coeytaux, Johannes Burtscher, Niran Maharjan, Laura Emmeline H Weerens

Parkinson’s disease (PD) is characterized by the accumulation of misfolded and aggregated α-synuclein (α-syn) into intraneuronal inclusions named Lewy bodies (LBs). Although it is widely believed that α-syn plays a central role in the pathogenesis of PD, t ...

Even-odd conductance effect in graphene nanoribbons induced by edge functionalization with aromatic molecules: basis for novel chemosensors

Oleg Yazyev, Michele Pizzochero, Kristians Cernevics

We theoretically investigate the electron transport in armchair and zigzag graphene nanoribbons (GNRs) chemically functionalized withp-polyphenyl and polyacene groups of increasing length. Our nearest-neighbor tight-binding calculations indicate that, depe ...

Time-lapse high-resolution microscopy to study the morphogenesis of microorganisms

Mélanie Thérèse Marie Hannebelle

Mycobacterium tuberculosis, the etiological agent for the tuberculosis disease, is a bacterial pathogen thought to infect about a quarter of the global human population. It is the first cause of death among infectious diseases, and is most prevalent in low ...

Spectro-electrochemical toolbox for monitoring and controlling quinone-mediated redox-driven molecular gripping

Jovana Milic, Thomas Schneeberger

The control of molecular systems by electrical charge or light is a prerequisite for their application in nanoelectronics. Such potential has been uniquely exploited in quinone-based resorcin[4]arene cavitands that can act as molecular grippers, reversibly ...

Probing the interaction of nanoparticles with small molecules in real time via quartz crystal microbalance monitoring

Stefan Guldin, Nikolaos Nianias, Ye Yang, Runzhang Qi

Despite extensive advances in the field of molecular recognition, the real-time monitoring of small molecule binding to nanoparticles (NP) remains a challenge. To this end, we report on a versatile approach, based on quartz crystal microbalance with dissip ...

Supramolecular Engineering for Formamidinium-Based Layered 2D Perovskite Solar Cells: Structural Complexity and Dynamics Revealed by Solid-State NMR Spectroscopy

Michael Graetzel, Shaik Mohammed Zakeeruddin, David Lyndon Emsley, Jovana Milic, Mohammad Ibrahim Dar, Dominik Józef Kubicki, Jiyoun Seo, Yang Li, Amita Ummadisingu, Jeong-Hyeok Im, Yang Li, Marco Alejandro Ruiz Preciado

Perovskite solar cells are one of the most promising photovoltaic technologies, although their molecular level design and stability toward environmental factors remain a challenge. Layered 2D Ruddlesden-Popper perovskite phases feature an organic spacer bi ...

Quantifying Guest-Host Dynamics in Supramolecular Assemblies to Analyze Their Robustness

Maartje Martina Cornelia Bastings, Eva Eugene Kurisinkal

The most basic function of synthetic microenvironments for tissue engineering is to act as a physical substrate for cell attachment, migration, and proliferation, similar to the natural cell environment. Functionalization of supramolecular materials with g ...

Molecular nanostructures based on polyfunctional clathrochelate complexes

Suzanne Maria Jansze

This thesis describes the design and synthesis of clathrochelate metalloligands for the construction of molecular nanostructures. The low synthetic effort, versatility and stability of the clathrochelate metalloligands makes them particularly suited to the ...

Specific Ion Effects at the Interface of Nanometer-Sized Droplets in Water: Structure and Stability

Sylvie Roke, Halil Ibrahim Okur, Evangelia Zdrali

The interaction of ions with interfaces influences numerous processes in chemistry, physics, and biology, while different ion species behave differently at hydrophobic or hydrophilic interfaces. Despite its importance, ion specificity and its relation to s ...

Scanning Probe Microscopy Characterization of Organic Self-Assembled Monolayers

Evangelia-Nefeli Athanasopoulou

As technology advances, surface coatings become more and more important to assure materials performances. In recent years, molecular coatings have found larger acceptance and uses. Among them, self-assembled monolayers (SAMs) are attractive because they ar ...

Host-guest chemistry with water-soluble gold nanoparticle supraspheres

Francesco Stellacci, Benjamin Timothée Nicolas Le Ouay

The uptake of molecular guests, a hallmark of the supramolecular chemistry of cages and containers, has yet to be documented for soluble assemblies of metal nanoparticles. Here we demonstrate that gold nanoparticle-based supraspheres serve as a host for th ...
