Modern Trends in Catalyst and Process Design for Alkyne Hydrogenations

Lioubov Kiwi, Fernando Cardenas Lizana, Rocio Micaela Crespo Quesada, Anne-Laure Dessimoz

This review provides an overview of the recent achievements in catalytic process development for alkyne hydrogenations. It underlines the necessity of simultaneous optimization over different length scales from molecular/nanoscale of active phase, up-to ma ...

Increased imaging speed and force sensitivity for bio-applications with small cantilevers using a conventional AFM setup

Georg Fantner

In this study, we demonstrate the increased performance in speed and sensitivity achieved by the use of small AFM cantilevers on a standard AFM system. For this, small rectangular silicon oxynitride cantilevers were utilized to arrive at faster atomic forc ...

The Single-Molecule Mechanics of the Latent TGF-beta 1 Complex

Jean-Jacques Meister, Boris Hinz, Lara Buscemi Estefanell, Aurélie Formey de Saint Louvent, Josiane Angèle Charlotte Smith-Clerc, David Ramonet Jimenez

Background: TGF-beta 1 controls many pathophysiological processes including tissue homeostasis, fibrosis, and cancer progression. Together with its latency-associated peptide (LAP), TGF-beta 1 binds to the latent TGF-beta 1-binding protein-1 (LTBP-1), whic ...

Molecular electrocatalysis at soft interfaces

Hubert Girault

The fundamental aspects of electrochemistry at liquid–liquid interfaces are introduced to present the concept of molecular electrocatalysis. Here, a molecular catalyst is adsorbed at the interface to promote a proton coupled electron transfer reaction such ...

Biomolecular Diffusion in Nanofluidics

Nicolas Durand

Imagine a small integrated biomedical analysis laboratory, connected to your home computer, which would be capable of diagnosing illnesses, a lack of vitamins, or the over-presence of substances from samples of blood, urine or saliva. This hypothetic syste ...

Relaxation Dynamics of Tryptophan in Water: A UV Fluorescence Up-Conversion and Molecular Dynamics Study

Majed Chergui, Frank van Mourik, Andrea Cannizzo, Ahmad Ajdar Zadeh Oskouei

We report on an ultrafast experimental and simulations study of the early relaxation events of photoexcited tryptophan in water. Experimentally, we used fluorescence up-conversion in both polychromatic and single wavelength detection modes in the 300-480 n ...

Measurement of Site-Specific C-13 Spin-Lattice Relaxation in a Crystalline Protein

David Lyndon Emsley

We demonstrate that it is possible to record site-specific spin-lattice relaxation rates for the majority of C-13 sites in uniformly C-13 and N-15 labeled solid proteins as a result of the slowing down of proton-driven spin diffusion at sample spinning fre ...

Sliding of rough surfaces and energy dissipation with a 3D multiscale approach

Jean-François Molinari, Guillaume Anciaux

The purpose of this paper is to present a novel approach to study sliding friction by the use of 3D multiscale coupling techniques. We highlight the difficulties of using multiscale schemes that couple molecular dynamics (MD) with finite elements to perfor ...

Long-range energy transfer in proteins

Francesco Piazza

Proteins are large and complex molecular machines. In order to perform their function, most of them need energy, e. g. either in the form of a photon, as in the case of the visual pigment rhodopsin, or through the breaking of a chemical bond, as in the pre ...

The tail sheath structure of bacteriophage T4: a molecular machine for infecting bacteria

Petr Leiman

The contractile tail of bacteriophage T4 is a molecular machine that facilitates very high viral infection efficiency. Its major component is a tail sheath, which contracts during infection to less than half of its initial length. The sheath consists of 13 ...
