Atomic bonding effects in annular dark field scanning transmission electron microscopy. I. Computational predictions

Annular dark field scanning transmission electron microscopy (ADF-STEM) image simulations were performed for zone-axis-oriented light-element single crystals, using a multislice method adapted to include charge redistribution due to chemical bonding. Exami ...

In Situ TEM Analysis of Organic-Inorganic Metal-Halide Perovskite Solar Cells under Electrical Bias

Christophe Ballif, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Björn Niesen, Jérémie Werner, Martial Duchamp

Changes in the nanostructure of methylammonium lead iodide (MAPbI(3)) perovskite solar cells are assessed as a function of current-voltage stimulus by biasing thin samples in situ in a transmission electron microscope. Various degradation pathways are iden ...

A multi-purpose imaging endstation for high-resolution micrometer-scaled sub-second tomography

Goran Lovric, Marco Stampanoni

Time-resolved imaging of dynamic processes, ranging from biological in vivo studies to materials under in situ and in operando conditions, requires a flexible endstation capable of controlling complex components that interact in different configurations an ...

Flexural strength of micron-scale plate-like silicon in aluminum

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller, Marta Fornabaio

Mechanical properties of composite materials and alloys are strongly influenced by the intrinsic mechanical properties of the reinforcing phases they contain; however, due to the irregular shape and small size of particulate reinforcements, measuring their ...

Picosecond pulsed laser for microscale sample preparation

Helena Van Swygenhoven, Steven Van Petegem, Ainara Irastorza Landa

Ultra short pulsed laser ablation is applied for preparing samples suitable for micromechanical testing. Laue microdiffraction shows that the micromachining hardly damages the initial microstructure. The technique has the potential to be a promising altern ...

Influences of porous reservoir Laplace pressure on emissions from passively fed ionic liquid electrospray sources

Herbert Shea, Daniel George Courtney

Passively fed ionic liquid electrospray sources are capable of efficiently emitting a variety of ion beams with promising applications to spacecraft propulsion and as focused ion beams. Practical devices will require integrated or coupled ionic liquid rese ...

Duality in the Escherichia coli and methicillin resistant Staphylococcus aureus reduction mechanism under actinic light on innovative co-sputtered surfaces

César Pulgarin, Juan Kiwi, Danièle Laub, Sami Rtimi, Rosendo Sanjines, Myriam Koumba Sarah Ballo

The kinetics of bacterial reduction of Staphylococcus aureus (MRSA) on co-sputtered TiO2/Cu-polyester (TiO2/Cu-PES) was found to be little dependent on the applied light dose. But in the case of Escherichia coil, the bacterial reduction kinetics was observ ...

Probing the Strength and Fracture Toughness of Hard Second Phases at the Micron Scale

Andreas Mortensen, Marco Cantoni, Goran Zagar, Andreas Rossoll, Martin Guillermo Mueller, Václav Pejchal, Marta Fornabaio, Lionel Michelet

It is known that the mechanical properties of composite materials and alloys are influenced by the intrinsic mechanical properties of their reinforcements or second phases. It is however challenging to determine such local properties, given their small siz ...
