MEMS Tunable Littman-Metcalf Diode Laser at 2.2μm for Rapid Broadband Spectroscopy in Aqueous Solutions
(2018)We demonstrate a rapidly (3 ms) and widely (222 nm) tunable, compact external cavity GaSb-based diode laser with a MEMS mirror. It delivers from 8 to 24 mW power over the tuning range, showing the side-mode suppression ... -
Metallization of Si heterojunction solar cells by nanosecond laser ablation and Ni-Cu plating
(2017)A key step in industrialization of photovoltaics (PV) is the development of low-cost and large-area metallization processes to substitute the standard screen-printing process of silver paste. Thus Cu and Ni metallization ... -
Meteor studies in the framework of the JEM-EUSO program
(2017)We summarize the state of the art of a program of UV observations from space of meteor phenomena, a secondary objective of the JEM-EUSO international collaboration. Our preliminary analysis indicates that JEM-EUSO, taking ... -
Microcrack characterization in loaded CFRP laminates using quantitative two- and three-dimensional X-ray dark-field imaging
(2018)In this work we present a method to characterize microcracks in carbon fiber reinforced polymer (CFRP) samples with a diameter up to 120 mm using quantitative grating-based X-ray dark-field imaging. In contrast to conventional ... -
Mid-infrared two photon absorption sensitivity of commercial detectors
(2017-10-23)We report on broad-band two-photon absorption (TPA) in several commercially available MIR inter-band bulk semiconductor photodetectors with the spectral cutoff in the range of 4.5–6??m. The highest TPA responsivity of ... -
Mid-IR DIAL for high-resolution mapping of explosive precursors
(2013-10-22)A DIAL instrument on a moving platform is seen as a valuable remote sensing component in a sensor network for area monitoring, targeting sites involved in unauthorised explosive manufacturing. Such instrument will perform ... -
Minimum Energy Point in Constant Frequency Designs under Adaptive Supply Voltage and Body Bias Adjustment in 55 nm DDC
(2019)In this paper, we describe a systematic low-power design methodology for technologies that offer a strong body factor. Specifically, we explore both the body bias voltage and the supply voltage knobs in order to find the ... -
Mode locking in monolithic two-section InGaN blue-violet semiconductor lasers
(2013-03-25)Passive mode-locked pulses with repetition frequencies in the range 40 to 90?GHz were observed in blue-violet GaN-based quantum-well lasers without external cavities. The lasers had two-section geometry with built-in ... -
Mode-locked microwave atomic clock laser: A concept

Modeling Potential-Induced Degradation (PID) of Field-Exposed Crystalline Silicon Solar PV Modules: Focus on a Regeneration Term
(2017)In this work, we further elaborate a model that was previously presented to simulate the effect of potential-induced degradation (PID) on the performance of field-exposed modules. We add to the predictive model a term aimed ... -
Modelling of C/Cl isotopic behaviour during chloroethene biotic reductive dechlorination: Capabilities and limitations of simplified and comprehensive models
(2018-08-22)Predicting the fate of chloroethenes in groundwater is essential when evaluating remediation strategies. Such predictions are expected to be more accurate when incorporating isotopic parameters. Although secondary chlorine ... -
Monitoring physiological and behavioral signals to detect mood changes of bipolar patients
(2011)In this paper we present a personal, cost-effective, multi-parametric monitoring system based on textile platforms and portable sensing devices for the long term and short term acquisition of data from bipolar patients ...
