Metal-tip-based electron sources are constrained by a trade-off between energy spread and pulse width. Here the authors report a carbon-nanotube-based electron source with a 0.3-eV energy spread and an electron pulse width of about 13 fs.

Cell migration in confined environments is initiated by a cytoplasmic pool of anillin and Ect2 that promotes RhoA/myosin II-mediated activation at the poles of migrating cells, in a process dependent on the extracellular environment stiffness.

Formation of a stable self-assembled monolayer for high-efficiency perovskite solar cells remains a challenge. Here uniform and stable SAM anchoring is achieved on a hydroxylated ITO surface, leading to highly efficient stable perovskite solar cells.

Here a droplet-driven nanoribbon-to-film growth strategy is reported to achieve amorphous metal chalcogenides at the single-layer limit.

A universal, high-resolution printing technology for metal oxide thin-film transistors is lacking. A plasmonic printing technology fabricates solution-processed all-metal oxide thin-film electronics under room temperature and ambient conditions.

Here the authors resolve the phonon dynamics and band structures of five different self-assembled nanoparticle lattices, revealing the role of nanoscale colloidal interactions in modulating the lattice properties.

The authors use nitrogen-vacancy centre magnetometry to explore layer number and magnetic field evolution of ferromagnetic and antiferromagnetic domains in the A-type antiferromagnet CrPS4.

A hybrid ECM-hydrogel with tunable mechanical stiffness and biochemical composition of young or aged cardiac tissue is used to identify the specific contributions of ECM ligands and mechanics for fibroblast aging. @nano_jenn
