Thus, the wire remains intact even when bent. Only when the copper grains are smaller than one thousandth of a millimeter, the properties change and therefore the metal's behavior:
PDMS Pillars with Nanoindenter
Important parameters are the tip's depth of indentation, the energy needed, or the way the pillars are crushed during the scanning. The whole process is done in a dimension of only a few millionths of millimeters. "For the measurements, we use a special nanoindenter developed by Hysitron, whose measuring possibilities were tailored especially to our needs", the materials expert explains. Usually, hard probes, i.e. metals, ceramic or even nacre, can be examined with such equipment. But it is no problem to also examine smooth probes, such as plastics, with the specially developed equipment.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
