Demonstration of an All‐Optical AND Gate Mediated by Photochromic Molecules

Advanced Functional Materials, EarlyView.
A logic AND gate that runs on photons is demonstrated. It relies on two spatially separated photochromic molecules that work in tandem. Abstract The realization of a photonic logic AND gate, i.e. a logic AND gate that runs on photons rather than electrons, and where all steps are controlled by light, is demonstrated. In a proof‐of‐principle experiment,

Photon mass

International Journal of Physics and Applications, 2018
The atomic structure is presented on the basis of the theory of vortex gravitation. The feasibility and calculation of the values of the density and mass of electromagnetic particles are proposed. A calculation is made, which proves that the photon must have mass.

Double Helical Plasmonic Antennas

Advanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Cell‐Delivering Injectable Hydrogels with Tunable Microporous Structures Improve Therapeutic Efficacy for Volumetric Muscle Loss

Advanced Functional Materials, EarlyView.
The study presents an injectable hydrogel with tunable microporosity to improve mesenchymal stem cell delivery for volumetric muscle loss treatment. Mesenchymal stem cells encapsulated in porous hydrogels significantly promote the spreading, proliferation, and cytokine secretion of mesenchymal stem cells.
