Pioneering the nanoscale exploration of biomolecules and materials

Simone Ruggeri, Associate Professor leading the Nanoscale Microscopy and Spectroscopy group at Wageningen University (WUR), Netherlands, tells us more about his current projects in the development of nano-analytical imaging and spectroscopic technologies to open a new research window of observation with nanoscale sensitivity in chemistry, biology and materials science.

Revealing key topographic parameters in surface bacterial adhesion

In the realm of dental implantology, understanding bacterial adhesion mechanisms is essential. Recent research led by Steve Papa and fellow researchers at the Jean Monnet University in Saint-Étienne, France, revealed the intricate relationship between surface topography and bacterial adhesion, with a particular focus on Porphyromonas gingivalis, a bacterium closely associated with dental implant failure.

How can color segmentation complement topographical analysis?

With the introduction of the new Color segmentation tool in Mountains® software, it is now possible to complement topographical wear analysis. Mathieu Cognard, product manager at Digital Surf, explains how MountainsImage® can help visualize & analyze your results.

Quantitative mapping of mechanical and viscoelastic properties at the nanoscale

In the last few years, the use of SPM techniques in many areas of research has greatly increased. Professor Philippe Leclere, director of the LPNE at the University of Mons (UMONS) in Belgium, has been studying the impact of this increase and describes how his team is addressing the challenge of analyzing and mapping large quantities of data on material properties at the nanoscale.

Analyzing silicon strain with Raman spectroscopy

Strain in semiconductor devices can be used to influence the electronic properties, and is used as so in strain engineering. Renata Lewandowska, product manager for spectral applications at Digital Surf, explains why Raman spectroscopy is an ideal technique for measuring strain, and give us an example.

Correlative microscopy enables comprehensive analysis of geological samples

Application experts at Horiba Scientific and JEOL Europe recently highlighted a technique for precisely relocalizing specific areas of a sample for analysis using various techniques including Raman microscopy, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS).

Multi-perspective characterization of tool performance

One of the critical applications of optical metrology in tooling is the dimensional characterization of cutting tools. Roughness measurements can also be used to predict how removed material will exit the tool in the aim of preventing clot formation or overheating. In addition, optical metrology can provide local measurements to help identify issues such as chipping or coating peeling, which indicate if a tool needs to be replaced or repaired. In this study, all these characterizations were managed using one, unique set-up: the Sensofar S neox Five Axis and SensoMap software powered by Mountains®.

AFM image analysis: determining surface quality of cap layers in superconductors

Researchers at the Institut de Ciència de Materials de Barcelona characterizied surface texture of superconductor materials with the aim of improving their performance.

Using microwear analysis to understand what T-rex ate

Dr. Mugino O. Kubo Ph.D at the University of Tokyo, Japan speaks about how her team are using three-dimensional microwear analysis and implementing new methods for studying the paleodiet of carnivorous dinosaurs, including the iconic Tyrannosaurus rex.

Imaging fish scale topography in situ

Researchers at Purdue and Harvard universities explored fish scale surfaces in 3D using MountainsMap® software.

Force spectroscopy: strengthening polylactic acid polymers by calcification

A team at Widener University (Chester, Pennsylvania, USA) recently used bimodal AFM technique and MountainsSPIP® software to study the calcification process of polylactic acid polymer (PLA), a plastic filament material widely used in 3D printing.

Snow surfaces investigated in situ on ski friction

A comprehensive description of the surface of snow is crucial for understanding the tribological system between skis and snow. Felix Breitschädel, of the Norwegian Olympic Sports Center, tells us how a novel measurement device is changing our understanding of the surface of snow and constitutes a promising method for future research.
