Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

SPATIAL DYNAMICS OF THE RADIALLY POLARIZED VORTEX BEAMS OF TERAHERTZ-RANGE RADIATION SUBJECTED TO TIGHT FOCUSING [PDF]
Subject and Purpose. The paper concerns the effect of tight focusing of the terahertz-range vortex laser beams, formed byradially polarized TM0m modes of a dielectric waveguide-based resonator, that results from beam’s passage through a spiral phase ...

Experimental and Numerical Investigation of Unforced unsteadiness in a Vaneless Radial Diffuser [PDF]
The paper reports combined experimental and numerical investigations of unforced un- steadiness in a vaneless radial diffuser. Experimental data were obtained within the diffuser using stereoscopic time resolved Particle Image Velocimetry (PIV) recording

In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

The theoretical impact polarization of the O I 6300 Å red line of Earth aurorae [PDF]
We are presenting a semi-classical theory of the impact polarization due to a quadrupolar electric excitation, which is the case of this forbidden line. In addition, this line is also radiatively forbidden being a triplet-singlet transition. This last
