2000-times repeated imaging of strontium atoms in clock-magic tweezer arrays [PDF]

, 2018
We demonstrate single-atom resolved imaging with a survival probability of $0.99932(8)$ and a fidelity of $0.99991(1)$, enabling us to perform repeated high-fidelity imaging of single atoms in tweezers for thousands of times. We further observe lifetimes

Optical Tweezers: Phototoxicity and Thermal Stress in Cells and Biomolecules [PDF]

Micromachines, 2019
For several decades optical tweezers have proven to be an invaluable tool in the study and analysis of myriad biological responses and applications. However, as with every tool, they can have undesirable or damaging effects upon the very sample they are ...

A Biologically‐Architected Wear and Damage‐Resistant Nanoparticle Coating From the Radular Teeth of Cryptochiton stelleri

Advanced Functional Materials, EarlyView.
The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

Microscopic Control and Detection of Ultracold Strontium in Optical-Tweezer Arrays

Physical Review X, 2018
Optical tweezers provide a versatile platform for the manipulation and detection of single atoms. Here, we use optical tweezers to demonstrate a set of tools for the microscopic control of atomic strontium, which has two valence electrons.

Biobased Bionic Spider Silk via Electrostatic Complexation for Simultaneously Harvesting Atmospheric Water and Triboelectric Energy

Advanced Functional Materials, EarlyView.
Bio‐based bionic spider silk and spider web are first prepared using polyelectrolyte complexation technique for the simultaneous harvesting of water and triboelectric energy. The advantage of this process lies on entirely bio‐based materials, fully green water‐processable procedures, extremely high production rate (99.36%), excellent fog harvesting ...

Orbital angular momentum 25 years on [invited] [PDF]

, 2017
Twenty-five years ago Allen, Beijersbergen, Spreeuw, and Woerdman published their seminal paper establishing that light beams with helical phase-fronts carried an orbital angular momentum. Previously orbital angular momentum had been associated only with

Folding a focalized acoustical vortex on a flat holographic transducer: Miniaturized selective acoustical tweezers [PDF]

Science Advances, 2018
Selective manipulation of micrometric objects in a standard microscopy environment is possible with miniaturized acoustical tweezers. Acoustical tweezers based on focalized acoustical vortices hold the promise of precise contactless manipulation of ...
