Two‐Dimensional Isotropic Spatial Differentiation Through Complete Polarization Control

open access: yesAdvanced Optical Materials, EarlyView.
This work enables two‐dimensional isotropic spatial differentiation at planar interfaces over a wide range of incident angles by extending the output polarization from linear to elliptical. The choice of incident angle can be used to balance broader spectral response at low angles and higher edge‐detection efficiency at larger angles.

Dielectric Permittivity Tensor of Muscovite for Next Generation All Van Der Waals Broadband Photonic Components

open access: yesAdvanced Optical Materials, EarlyView.
Low‐index and low‐loss vdW muscovite represents an emerging robust dielectric platform for the creation of next‐generation all‐vdW nanophotonic architectures. Its utilization as a low‐index building‐block in all‐vdW multilayers enables extreme optical contrast when paired with MoS2, paving the way to the realization of few‐layer ultrathin DBS ...

Inverse Optical Contrast in Metastable GeTe2: An Anomaly Enabling Low‐Loss Phase Change Photonics

open access: yesAdvanced Optical Materials, EarlyView.
An anomalous optical phase inversion in GeTe2$\mathrm{GeTe_{2}}$ provides a new platform for low‐loss non‐volatile integrated photonics at 1550 nm. The transition from the amorphous state (1) to a metastable vdW−GeTe2$\mathrm{vdW-GeTe_{2}}$ crystalline phase (2) is driven by bandgap widening, resulting in a negative refractive index change (Δn$\Delta ...

Demokratie – zwischen Kampfbegriff und Nebelkerze. Was können Sprach-, Medien- und Kulturwissenschaften zur Demokratisierung von Gesellschaft beitragen?

open access: yesLinguistik Online, 2015
Everybody speaks about democracy. In current media discourses, 'democracy' means every-thing and nothing. You can explain war as "democratization" (of Iraq, Afghanistan etc.) just as well as you can call a referendum about fundamental political decisions

Technical Feasibility Study of Autonomous Field Robot‐Based on‐the‐go Assessment of Soil Nutrients Using Ion‐Sensitive Field‐Effect Transistors

open access: yesAdvanced Robotics Research, EarlyView.
Autonomous field robots equipped with ISFET‐based sensors enable rapid, spatially resolved soil nutrient analysis directly in the field. An automated system based on the BoniRob platform is presented for standardized on‐site extraction and measurement of key macronutrients and soil pH.

Ideological attitudes predicting online hate speech: the differential effects of right-wing authoritarianism and social dominance orientation

open access: yesFrontiers in Social Psychology
IntroductionWhile research on online hate speech (OHS) has expanded in recent years, only few studies adopt a theoretical framework to understand how ideological attitudes differentially motivate individuals to engage with OHS.
