Programmable solar‐blind ultraviolet sensors enabling integrated single‐pixel sensing and neuromorphic processing

open access: yesInfoMat, EarlyView.
A Schottky photodiode based on (Al0.14Ga0.86)2O3 was developed, in which the sensing and processing functions were temporally decoupled through bias voltage modulation. By integrating single‐pixel imaging with a reservoir computing architecture, a comprehensive intelligent vision system was constructed.

The German Soil Systematics and the Rationale Behind Its Revision

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background The German Soil Systematics is a pedogenetic classification based on the morphological expressions of pedogenic processes and has been developed over several stages since 1952. The system has successfully been in use for soil classification and soil survey for almost 70 years.

New constraints on the postglacial evolution of Lago Maggiore, Northern Italy

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Lago Maggiore is situated in an overdeepened valley reach at the southern margin of the European Alps, and its thick sediment infill allows the reconstruction of the postglacial valley and lake evolution. We study here the sedimentary succession in the lower Ossola Valley, which is infilled by ~500 m of deposits. In a marginal position, a core

Evolution of Pigments in Artificially Aged Polyethylene Plastics: A Raman Study

open access: yesJournal of Raman Spectroscopy, EarlyView.
The evolution of specific pigments included in plastics exposed to UVA is studied using Raman spectroscopy. This approach is applicable to both organic and inorganic pigments and is facilitated by resonance mechanisms. ABSTRACT The degradation mechanisms of polymers under UV exposure and the evolution of additives are a major concern due to their ...

Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis

open access: yesLaser &Photonics Reviews, EarlyView.
We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...

Toward Low‐Power Laser Refrigeration ‐ Cooling a Resonant WGM Crystalline Cavity

open access: yesLaser &Photonics Reviews, EarlyView.
Laser refrigeration offers a method to cool solids to low temperatures by using only light. By illuminating bulk crystals doped with rare‐earth ions one can engineer the emitted fluorescent light to be at shorter wavelengths than the pump light ‐ thus extracting heat/phonons from the solid and cooling the crystals.
