Inspired by the human visual system, a vision chip with primitive-based complementary pathways is developed to overcome the power and bandwidth wall of vision systems, achieving fast, precise, robust and high-dynamic-range sensing efficiently in the open world.
Hot-cracking during laser additive manufacturing of high-strength aluminum alloys is a common issue. Here, crack resistance is improved by approximately 50% by using a pulsed laser with ramp-down power modulation during in-situ x-ray imaging.
3D skyrmion strings are topological spin textures promising for spintronics applications, but their manipulation and dynamics are challenging to understand. Here, high-resolution 3D phase imaging reveals the melting dynamics of metastable skyrmions, accompanied by the emergence of (anti)hedgehogs, in (Fe,Ni,Pd)3P and FeGe helimagnets.
A non-common-path interferometric scheme enables holographic detection of single proteins of mass 90 kDa and estimation of single-protein polarizability.
A distance-based mapping strategy using single-molecule fluorescence resonance energy transfer via DNA eXchange (FRET X) enables full-length fingerprinting of intact protein sequences.
The ability to extract information from diffuse background signals in ultrafast electron diffraction experiments now enables a direct view of the formation of topological defects during a light-induced phase transition.
The antiferromagnetic material haematite, named for its blood-red colour, hosts swirling spin vortices termed merons. The rotation sense of such antiferromagnetic vortices has now been imaged in real space.
