Light-Driven Microdrones Offer Nanosensing, Motion Possibilities
Light-Driven Microdrones Offer Nanosensing, Motion Possibilities
Physicists at the University of Würzburg have used light to propel micrometer-size objects in an aqueous environment and control them precisely on a surface with all three degrees of freedom — two translational degrees and a rotational degree. The scientists said that the demonstration of this level of control over nano- and micro-objects opens possibilities to precisely control the assembly of nanostructures, such as for the analysis of surfaces with nanometer precision.

Shimadzu Europa GmbH - Ultra-High-Speed 3D-DIC Analysis by 2x HPV-X2 Ultra-High-Speed 3D-DIC Analysis by 2x HPV-X2

Shimadzu Europa GmbH
Silicon (Si) wafers, are the main material for semiconductor devices, have reached a size of φ300 mm and more but have a thickness of only 1 mm or less, and great care is necessary in handling these hard, brittle wafers. Here, high-speed deformation of a Si wafers was visualized by 3D-DIC (3D Digital Image Correlation)...

Remote Sensing, Neural Networks Combine to Measure Tree Height
Remote Sensing, Neural Networks Combine to Measure Tree Height
Scientists at ETH Zurich’s EcoVision Lab have developed a deep learning framework to map treetop height globally at high resolution, using publicly available optical satellite images as input. The Global Canopy Height Map is the first map of its kind. It could become a critical tool for tracking carbon emissions that contribute to climate change and for planning sustainable regional development.

European Initiatives Increase Access to Quantum Magnetometers
Researchers from six Fraunhofer institutes are working on two projects that aim to make quantum magnetometers — sensor devices that measure magnetic field — usable in industrial settings. Magnetometers are currently limited in such settings due to the complexity of their operation. Additionally, their spatial resolution is too low for many applications.

Self-Cleaning Optical Fiber Powers Supercontinuum Light Sources
Researchers at Tampere University collaborated with colleagues at the University of Warsaw and the University of Burgundy France-Comté to create a supercontinuum light source in the mid-infrared, using a nonsilica, graded-index, multimode fiber. The collaborators generated a two-octave supercontinuum in the fiber, which could create a path toward bright, ultrabroadband light sources for applications in the mid-infrared that require high spatial beam quality and high power.
