Iterative SuFEx approach for sequence-regulated oligosulfates and its extension to periodic copolymers

The synthesis of sequence-regulated oligosulfates has not yet been established due to the difficulties in precise reactivity control. Here, the authors report a multi-directional divergent iterative method to furnish oligosulfates based on a chain homologation approach, in which the fluorosulfate unit is regenerated.

Mechanochemistry-driven engineering of 0D/3D heterostructure for designing highly luminescent Cs–Pb–Br perovskites

While emission and stability of metal–halide perovskites can be enhanced through heterostructural encapsulation, a controlled synthesis route to such structures is not trivial to realize. Here, the authors design a mechanochemistry-driven protocol for synthesizing highly luminescent CsPbBr₃/Cs₄PbBr₆ heterostructures.

Ultrasensitive torque detection with an optically levitated nanorotor

A torque sensitivity of (4.2 ± 1.2) × 10⁻²⁷ N m Hz^−1/2 is achieved at room temperature. This sensitivity would be enough to measure vacuum friction.

Electron spin control of optically levitated nanodiamonds in vacuum

Hybrid systems coupling electron spins and optomechanical responses are of potential use in quantum information systems and sensing technology. Here, the authors demonstrate optical levitation of nanodiamonds and the control of their nitrogen vacancy spins in vacuum.
