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.

Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

Advanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

Optimizing (1‐x) BiFeO3‐xCaTiO3 Perovskites: A Pathway to Efficient Flexible Energy Storage

Advanced Functional Materials, EarlyView.
Perovskite materials, like BFO CTO, are popular due to their high conductivity, low cost, and wide availability. In this work a symmetric electrochemical cell based on BFO‐CTO shows a charge of 3.356 C.cm⁻2, giving a specific capacitance of 2.79 mF.cm⁻2 at 1 mV.s⁻2.

Printed circuit boards isomorphism: An experimental study

Computers & Industrial Engineering, 2020
We evaluate the discrimination power of different graph invariants in order to identify an appropriate measurement of similarity among printed circuit boards. We show that computationally expensive algorithmic evaluation of circuit boards equivalence based on the topology of the circuit boards is unnecessary in practice.
