First astronomical preselecting site in the Beni Mellal region: On the use of satellite data

Journal of Applied Surfaces and Interfaces, 2017
In this paper we use satellite meteorological and geophysical data to compare three new sites to the Oukaimeden Observatory (J43) located in the Atlas mountains (Morocco). The Three other sites are located in Beni Mellal mountains.

Surface figure metrology for reflective membrane mirrors based on phase-measuring deflectometry

Frontiers in Astronomy and Space Sciences
Reflective membrane mirrors provide a lightweight, low-cost alternative to traditional optics for next-generation large-aperture telescopes, but their non-rigid, thin structure poses challenges for surface metrology.

Rewiring Droplet Interface Synapses

Advanced Intelligent Systems, EarlyView.
Droplet interface synapses are used to create a neuromorphic network. Voltage pulses draw the droplets into contact and enable rewiring of the network through electrowetting. Results show that the heterogeneous droplet compositions and pore‐forming molecules may be used to tune the neuromorphic properties of the device using trapped charge as a form of

Photoluminescence Turn‐On Method to Determine the Kinetics of Thermally Activated Delayed Fluorescence Materials

Advanced Physics Research, EarlyView.
Thermally Activated Delayed Fluorescence (TADF) is widely exploited to achieve high‐efficiency OLEDs. TADF Emitters are normally investigated with transient photoluminescence (PL), which requires the PL to be detected over multiple orders of magnitude in time and intensity.
