Wavelength‐ and Helicity‐Reconfigurable Circularly Polarized Optical Diodes Enabled by Molecular Photoswitches

open access: yesAdvanced Materials, EarlyView.
All‐optical, photoswitchable diode‐type device for tunable nonreciprocal (asymmetric) transmission of CPL across a broad spectrum of light is demonstrated using molecular motor (photoswitch)‐doped cholesteric liquid crystals (CLCs) sandwiched between polyvinyl alcohol (PVA) and polydopamine (PDA)‐PVA composite layers.

Homophobia and Academic Freedom

open access: yesJournal of Lesbian Studies, 2002
SUMMARY Addressing homophobia and heterosexism as a teacher raises issues of respect for the intellectual freedom of your students. The central thesis of this article is that these issues are best addressed on the basis of general principles of academic freedom-that is, intellectual freedom in educational and research contexts. Three cases are analyzed

Controlled Growth of Boron Nitride in Various Phases

open access: yesAdvanced Materials Interfaces, EarlyView.
Phase‐selective boron nitride growth is presented as a unified materials‐design problem across hexagonal, rhombohedral, cubic, and amorphous phases. By linking synthesis routes to thermodynamic stability, kinetic accessibility, surface diffusion, interfacial templating, and energetic activation, this review clarifies how bonding and stacking are ...

Aerosol Jet Printing of Benzocyclobutene as a Thermally Stable, Low‐Loss Dielectric for Multilayer Microwave Electronics

open access: yesAdvanced Materials Technologies, EarlyView.
Multilayer aerosol jet printed components with a low‐loss, thermally stable dielectric are demonstrated using benzocyclobutene. Ink formulation and in‐line droplet evaporation control support high‐quality, versatile, and stable printing performance. A specialized measurement for low‐loss materials reveals promising microwave properties, which, combined
