S Zhang et al.
Electrocaloric effects have been experimentally studied in ferroelectrics and incipient ferroelectrics, but not incipient ferroelectrics driven ferroelectric using strain. Here we use optimally oriented interdigitated surface electrodes to ...
Near-room-temperature water-mediated densification of bulk van der Waals materials from their nanosheets [0.03%]
纳米片状物的近室温水介导的范德华材料致密化过程

Jiuyi Zhu et al.
The conventional fabrication of bulk van der Waals (vdW) materials requires a temperature above 1,000 °C to sinter from the corresponding particulates. Here we report the near-room-temperature densification (for example, ∼45 °C for 10 mi...
Inverse chirality-induced spin selectivity effect in chiral assemblies of π-conjugated polymers [0.03%]
手性π共轭聚合物聚集中逆手性诱导自旋选择效应

Coupling of spin and charge currents to structural chirality in non-magnetic materials, known as chirality-induced spin selectivity, is promising for application in spintronic devices at room temperature. Although the chirality-induced spin...

Unlike proteins, which have a wealth of validated structural data, experimentally or computationally validated DNA origami datasets are limited. Here we present a graph neural network that can predict the three-dimensional conformation of D...
Suppression of Dexter transfer by covalent encapsulation for efficient matrix-free narrowband deep blue hyperfluorescent OLEDs [0.03%]
共价封装抑制德克斯特转移以实现高效的无基质窄带深蓝超荧光OLED
Hwan-Hee Cho,Daniel G Congrave,Alexander J Gillett et al.
Hwan-Hee Cho et al.
Hyperfluorescence shows great promise for the next generation of commercially feasible blue organic light-emitting diodes, for which eliminating the Dexter transfer to terminal emitter triplet states is key to efficiency and stability. Curr...

The liquid-like feature of thermoelectric superionic conductors is a double-edged sword: the long-range migration of ions hinders the phonon transport, but their directional segregation greatly impairs the service stability. We report the s...

Thrombosis is a leading global cause of death, in part due to the low efficacy of thrombolytic therapy. Here, we describe a method for precise delivery and accurate dosing of tissue plasminogen activator (tPA) using an intelligent DNA nanod...
