Plant protection treatments in Switzerland using unmanned aerial vehicles: regulatory framework and lessons learned

Pest Management Science, EarlyView.
Unmanned aerial vehicles (UAVs) are increasingly used for plant protection treatments. We describe the corresponding Swiss regulatory framework. We also summarize practical experiences gained from technical assessments performed within this framework, field use patterns and the results of field efficacy trials.

Sputter Epitaxy of Transition Metal Nitrides: Advances in Superconductors, Semiconductors, and Ferroelectrics

physica status solidi (a), EarlyView.
In this review, sputter epitaxy is highlighted as a key technique for growing transition metal nitrides such as NbN and ScAlN. By integrating these materials with nitride semiconductors, hybrid devices showing both superconducting and ferroelectric properties can be realized.

Anticlastic Curvature and Material Freedom

physica status solidi (b), EarlyView.
Anticlastic curvature occurs in bent bars for positive Poisson's ratio; synclastic curvature occurs for negative Poisson's ratio provided the material is homogeneous and elastic. Some planar negative Poisson's ratio materials exhibit anticlastic saddle curvature rather than convex curvature in bending due to effects of 3D structure.

Rain in convective downdraughts

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents results from the simulation of idealised, rain‐laden downdraughts using the large‐eddy model MONC. It is found that a drier environment has the effect of increasing cooling in the downdraught, but reducing the peak in downdraught speed.
