QLEDs â light-emitting diodes that rely on nanocrystals called quantum dots â are usually made with toxic heavy metals. A strategy has been developed to make QLEDs with a performance comparable to that of commercially available technologies but using a more environmentally friendly alloy of zinc, selenium, telluriu

Lyu, Y., Su, Y., Nan, K. & Zhang, Y. Iontronics 2, 9 (2026). Chen, W. et al. Science 382, 559–565 (2023). Luo, J., Remy, A. & Zhang, Y. Chem. Rev. 125, 11840–11877 (2025). Pershin,…...
Taking the pulse of ultrafast spectroscopy - Nature Reviews Methods Primers
2+ day, 11+ hour ago (93+ words) Advances in ultrafast laser technology have revolutionized the study of time-resolved phenomena across physics, chemistry, biology and materials science. Here, Giulio Cerullo, a pioneer in the development of optical parametric amplifiers and their application to ultrafast spectroscopy, shares his perspective…...
Electric fields take control of ferrons - Nature Physics
2+ day, 15+ hour ago (176+ words) Nature Physics (2026) Cite this article Ferrons are the quasiparticles associated with the collective excitations of spontaneous polarization. External electric fields have now been shown to tune their properties in a nonvolatile manner. Rameshti, B. Z. et al. Phys. Rep. 979, 1–61 (2022). Pirro, P., Vasyuchka,…...
Weaving braids of defect lines - Nature Materials
2+ day, 16+ hour ago (175+ words) Nature Materials (2026) Cite this article Colloidal particles steered by light weave the defect lines of a nematic liquid crystal into programmable crossings, realizing non-Abelian braiding operations that can be watched, reordered and compiled in real space. Tkalec, U., Ravnik, M., Čopar, S.,…...
A hidden leak in solids - Nature Energy
2+ day, 16+ hour ago (230+ words) Nature Energy (2026) Cite this article Solid electrolytes have long been treated as materials that block electronic conduction while enabling fast lithium-ion transport. Two studies now show that residual electronic conductivity can drive self-discharge in solid-state batteries at open circuit, particularly…...
Current dipoles - Nature Physics
3+ day, 2+ hour ago (28+ words) Nature Physics volume 22, page 1379 (2026) Cite this article Correspondence to David Abergel. Version of record: 09 September 2026 Issue date: September 2026 Nature Physics (Nat. Phys.)...
Reproducibility by design - Nature Physics
3+ day, 5+ hour ago (245+ words) Nature Physics volume 22, page 1363 (2026) Cite this article The sensitivity of moiré materials to crystal quality and twist angle can make experimental results difficult to replicate. Reproducibility should therefore be built into material growth, device fabrication and experimental design from the…...

Electric charge makes drops of water more destructive
3+ day, 12+ hour ago (53+ words) In many real-world settings, water droplets can become slightly charged as they slide across solid surfaces. This charge has been found to enable water droplets to damage protective coatings more easily than uncharged droplets do, and to cause the underlying…...
Room-temperature correlated microwaves from magnons - Nature Electronics
4+ day, 8+ hour ago (111+ words) Nature Electronics (2026) Cite this article A tiny magnetic film placed atop a microwave circuit can be used to create a compact source of correlated microwave signals that operates at room temperature.
