Dynamic aggregation of chiral spinners.

Active turbulence in a gas of self-assembled spinners

Colloidal particles subject to an external periodic forcing exhibit complex collective behavior and self-assembled patterns. A dispersion of magnetic microparticles confined at the air-liquid interface and energized by a uniform uniaxial alternating magnetic field exhibits dynamic arrays of self-assembled spinners rotating in either direction. Here, we report on experimental and simulation stud...

Emergence of reconfigurable wires and spinners via dynamic self

Emergence of reconfigurable wires and spinners via dynamic self-assembly

Dissipative colloidal materials use energy to generate and maintain structural complexity. The energy injection rate, and properties of the environment are important control parameters that influence the outcome of dynamic self-assembly. Here we demonstrate that dispersions of magnetic microparticles confined at the air-liquid interface, and energized by a uniaxial in-plane alternating magnetic...

Electrochemical Chiral Recognition of Naproxen Using L-Cysteine/Reduced Graphene Oxide Modified Glassy Carbon Electrode

The electrochemical response of S- and R-naproxen enantiomers was investigated on L-cysteine/reduced graphene oxide modified glassy carbon electrode (L-Cys/RGO/GCE). The production of the reduced graphene oxide and L-cysteine on the surface of the glassy carbon electrode was done by using electrochemical processes. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were us...

Structured adaptive and random spinners for fast machine learning computations

We will introduce here an equivalent definition of the model of structured spinners that is more technical (thus we did not give it in the main body of the paper), yet more convenient to work with in the proofs. Note that from the definition of structured spinners we can conclude that each structured matrix Gstruct ∈ Rn×n from the family of structured spinners is a product of three main structu...
