TL;DR: The amount of flux introduced by individual vortices in a superconducting film is measured, finding that the flux always differs substantially from φ0, and ‘negative vortice’ are observed, whose penetration leads to the expulsion of magnetic field.

TL;DR: In this paper, it was shown that the stable levitation of a magnet can be achieved using the feeble diamagnetism of materials that are normally perceived as being non-magnetic, so that human fingers can keep a magnet hovering in mid-air without touching it.

TL;DR: In this article, the authors report measurements of the amount of flux associated with the entrance of individual vortices in a superconducting film and show that the flux that they bring in, always differs substantially from f0.

TL;DR: Measurements of this interfacial pressure are reported by capturing pressure-sensitive molecules and studying their structural and conformational changes, and it is shown that this pressure can induce chemical reactions, and several trapped salts are found to react with water at room temperature, leading to two-dimensional crystals of the corresponding oxides.

TL;DR: In this paper, a simple procedure to produce free-standing graphene membranes has been designed for imaging individual biological molecules in transmission electron microscope (TEM) and high contrast has been achieved even though no staining has been applied.
