Symmetry-controlled hybrid chiral-omega bianisotropy in knot-particle metasurface

open access: yesPhysical Review Research
Hybrid chiral-omega bianisotropic responses are challenging to achieve within a single metamaterial layer due to their distinct symmetry requirements.

Escaping the Scaling Relationships in Oxygen Reduction Catalysis: Implications for PEM Fuel Cells

open access: yesAdvanced Materials, EarlyView.
Escaping the scaling relationships of the oxygen reduction reaction is vital for hydrogen fuel cells. This outlook examines how interfacial heterogeneity, spanning the subsurface lattice, chemisorption layer, and near‐interface solvation volume, mechanistically decouples intermediate binding energetics.

Programmable Anisotropic Terahertz Permittivity via High‐Aspect‐Ratio 3D‐Printed Dielectric Mesh Networks

open access: yesAdvanced Optical Materials, EarlyView.
A 3D‐printed Terahertz (THz) anisotropic dielectric with programmable permittivity by varying infill density and creating high‐aspect‐ratio channels is presented. The proposed design was evaluated both experimentally, through THz time‐domain spectroscopy, and theoretically, through FDTD simulations and Effective Medium Theory analysis.

Information Transmission Strategies for Self‐Organized Robotic Aggregation

open access: yesAdvanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

From chiral laser pulses to femto- and attosecond electronic chirality flips in achiral molecules

open access: yesNature Communications
Chirality is an important topic in biology, chemistry and physics. Here we show that ultrashort circularly polarized laser pulses, which are chiral, can be fired on achiral oriented molecules to induce chirality in their electronic densities, with ...
