Absolute calibration and beam reconstruction of MITO (a ground-based instrument in the millimetric region)

open access: yes, 2003
An efficient sky data reconstruction derives from a precise characterization of the observing instrument. Here we describe the reconstruction of performances of a single-pixel 4-band photometer installed at MITO (Millimeter and Infrared Testagrigia ...

A Comparative Analysis of Plasmonic and Dielectric Metasurface Sensing Platforms Powered by Bound States in the Continuum

open access: yesAdvanced Functional Materials, EarlyView.
This work reveals a fundamental trade‐off between plasmonic and dielectric metasurfaces for molecular sensing. A clear performance crossover is identified: dielectric metasurfaces excel in air, while plasmonic metasurfaces dominate in lossy solvents. These results establish design rules for infrared metasurface sensors and enable optimized performance ...

Characteristics of extensive air showers around the energy threshold for ground-particle-based $$\gamma $$ γ -ray observatories

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
Very-high-energy $$\gamma $$ γ -ray astronomy based on the measurement of air shower particles at ground-level has only recently been established as a viable approach, complementing the well established air Cherenkov technique.

Heterogeneous Nanopore Arrays – Selective Modification of Nanopores Embedded in a Membrane

open access: yesAdvanced Materials, EarlyView.
Biological processes rely on the concerted action of channels with different functionalities embedded in the same membrane. Inspired by nature, heterogeneous nanopore arrays are prepared where two nanopores are connected in parallel and function as two different elements of an ionic circuit: a diode and a resistor.
