Polarization degrees-of-freedom in electronuclear hadron production from finite nuclei

open access: yes, 1998
The polarization degrees-of-freedom in electronuclear two-nucleon knockout reactions are discussed. Model calculations for the unpolarized $^{16}$O(e,e$'$pp) cross sections at ($\mid \vec{q} \mid$,$ω$)=(210 MeV,300 MeV/c) are compared to recently obtained data.

Monolithically 3D‐Printed Spectral‐Spatial Meta‐Authenticators

open access: yesAdvanced Materials, EarlyView.
A single height map printed in a low‐index resin by two‐photon lithography encodes multiple visible wavelengths in one metasurface without any polarization optics. A fabrication‐aware optimization folds the printable height levels into the design, so the device is printed as optimized.

From Water Vapor Transmission Rate (WVTR) to Intrinsic Water Vapor Permeability (WVP)

open access: yesAdvanced Materials, EarlyView.
Breathable membranes can appear less permeable when the measurement apparatus limits vapor transport. A calibrated four‐step model describes membrane permeation and apparatus effects as resistances in series under a common chemical‐potential driving force.
