On the formation of stacking fault tetrahedra in irradiated austenitic stainless steels – A literature review

Robin Schäublin, Raluca Schibli

Irradiated austenitic stainless steels, because of their low stacking fault energy and high shear modulus, should exhibit a high ratio of stacking fault tetrahedra relative to the overall population of radiation induced nanometric defects. Experimental obs ...

Stiffness tomography exploration of living and fixed macrophages

Giovanni Dietler, Sandor Kasas, Giovanni Longo, Charles Roduit

Stiffness tomography is a new atomic force microscopy imaging technique that allows highlighting structures located underneath the surface of the sample. In this imaging mode, such structures are identified by investigating their mechanical properties. We ...

Force volume and stiffness tomography investigation on the dynamics of stiff material under bacterial membranes

Giovanni Dietler, Sandor Kasas, Giovanni Longo, Charles Roduit

The determination of the characteristics of micro-organisms in clinical specimens is essential for the rapid diagnosis and treatment of infections. A thorough investigation of the nanoscale properties of bacteria can prove to be a fundamental tool. Indeed, ...

Atomic Force Microscopy Stiffness Tomography on Living Arabidopsis thaliana Cells Reveals the Mechanical Properties of Surface and Deep Cell-Wall Layers during Growth

Giovanni Dietler, Sandor Kasas, Charles Roduit

Cell-wall mechanical properties play a key role in the growth and the protection of plants. However, little is known about genuine wall mechanical properties and their growth-related dynamics at subcellular resolution and in living cells. Here, we used ato ...

Fluorine-18 labeling of three novel D-peptides by conjugation with N-succinimidyl-4-[F-18]fluorobenzoate and preliminary examination by postmortem whole-hemisphere human brain autoradiography

Andrea Pfeifer

Introduction: beta-Amyloid (A beta) plaques and neurofibrillary tangles are the main characteristics of Alzheimer's disease (AD). Positron emission tomography (PET), a high-resolution, sensitive, and noninvasive imaging technique, has been widely utilized ...

Imaging with second-harmonic radiation probes in living tissue

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu, Thomas Jean Victor Marie Lanvin

We demonstrate that second-harmonic radiation imaging probes are efficient biomarkers for imaging in living tissue. We show that 100 nm and 300 nm BaTiO3 nanoparticles used as contrast markers could be detected through 50 mu m and 120 mu m of mouse tail ti ...

Sawtooth control in ITER using ion cyclotron resonance heating

Olivier Sauter, Jonathan Graves, Martin Jucker

Numerical modelling of the effects of ion cyclotron resonance heating (ICRH) on the stability of the internal kink mode suggests that ICRH should be considered as an essential sawtooth control tool in ITER. Sawtooth control using ICRH is achieved by direct ...

An Isotropic Auxetic Structural Network with Limited Shear Stiffness

Alessandro Spadoni

The chiral lattice is a unique structural network not symmetric to its mirror image, and with a negative Poisson’s ratio. Previous investigations have considered this structural network for the design of superior structural components with sandwich constru ...
