TL;DR: The observation of the quantum anomalous Hall (QAH) effect in thin films of chromium-doped (Bi,Sb)2Te3, a magnetic topological insulator shows a plateau in the Hall resistance as a function of the gating voltage without any applied magnetic fields, signifying the achievement of the QAH state.

TL;DR: A technique for generic bottom-up synthesis of complex quantum devices with a special focus on nanowire networks with a predefined number of superconducting islands is demonstrated, opening up new avenues for the realization of epitaxial three-dimensional quantum architectures which have the potential to become key components of various quantum devices.

TL;DR: The transition of vertical-to-horizontal growth directions in 2D molybdenum (or tungsten) disulfide is investigated and the thickness of metal seed layers plays a critical role in determining their growth directions, paving a way for developing a new class of 2D TMDCs with unconventional materials properties.

TL;DR: The state of the art is presented, insights learned from reviewing ECHA published decisions regarding the relative successes/pitfalls surrounding read-across under REACH are summarized, and the relevant activities and guidance documents are compiled.

TL;DR: It is demonstrated that superconducting quantum interference devices can be constructed based on the proximity-effect-induced superconductivity, and the critical current of the devices exhibits s-wave-like interference and Fraunhofer diffraction patterns.
