An internet of things-based intensity and time-resolved fluorescence reader for point-of-care testing
A miniature internet of things (IoT)-based point-of-care testing (PoCT) fluorescence reader, able to perform both intensity and time-resolved measurements of different fluorescent tags, is presented. This low cost platform ...
Status of the Belle II Pixel Detector
The Belle II experiment at the super KEK B-factory (SuperKEKB) in Tsukuba, Japan, has been collecting e+e− collision data since March 2019. Operating at a record-breaking luminosity of up to 4.7×1034 cm−2s−1, data corresponding ...
ZIF-8-Based Surface Plasmon Resonance and Fabry–Pérot Sensors for Volatile Organic Compounds
This work explores the use of ZIF-8, a metal–organic framework (MOF) material, for its use in the optical detection of volatile organic compounds (VOCs) in Fabry–Pérot and surface plasmon resonance (SPR)-based sensors. The ...
The DMAPS upgrade of the Belle II vertex detector
The Belle II experiment at KEK in Japan considers an upgrade for the vertex detector system in line with the accelerator upgrade for higher luminosity at long shutdown 2 planned for 2028. One proposal for the upgrade of ...
Enhancing the detection of low-energy M dwarf flares: wavelet-based denoising of CHEOPS data
Stellar flares are powerful bursts of electromagnetic radiation triggered by magnetic reconnection in the chromosphere of stars, occurring frequently and intensely on active M dwarfs. While missions like TESS and Kepler ...
Soft topographical patterns trigger a stiffness-dependent cellular response to contact guidance
Topographical patterns are a powerful tool to study directional migration. Grooved substrates have been extensively used as in vitro models of aligned extracellular matrix fibers because they induce cell elongation, ...

Unidirectional Synchronization of Silicon Optomechanical Nanobeam Oscillators by External Feedback
The remote synchronization of oscillators is essential for improving the performance, efficiency, and reliability of various systems and technologies, ranging from everyday telecommunications to cutting-edge scientific ...
WhatEELS. A new software solution for ELNES analysis
WhatEELS is a free software tool based in Python, specifically designed to facilitate the combined use of clustering and non-linear least squares (NLLS) fitting for the analysis of Energy Loss Near Edge Structures (ELNES) ...
Oxide wizard: a script to characterize white lines of transition metal edges in EELS spectra
The scripts 0 and 1 have to be installed in the library, while 2 and 3 can be installed as menus. Please install the scripts in order. Open the oxide wizard from the menu, then, follow the instructions. When dealing with ...
Mimicking human skin constructs using norbornene-pullulan-based hydrogels
There has been a huge demand for engineered skin tissues in the realms of both in vitro and in vivo applications. Selecting the right material scaffold is a critical consideration in making engineered skin tissues, since ...
On-line event detection by recursive dynamic principal component analysis and gas sensor arrays under drift conditions
Leakage detection is an important issue in many chemical sensing applications. Leakage detection hy thresholds suffers from important drawbacks when sensors have serious drifts or they are affected by cross-sensitivities. ...
High quality InAlN single layers lattice-matched to GaN grown by molecular beam epitaxy
We report on properties of high quality 60 nm thick InAlN layers nearly in-plane lattice-matched to GaN, grown on c-plane GaN-on-sapphire templates by plasma-assisted molecular beam epitaxy. Excellent crystalline quality ...
Properties of Nanocrystalline Silicon Probed by Optomechanics
Nanocrystalline materials exhibit properties that can differ substantially from those of their single crystal counterparts. As such, they provide ways to enhance and optimize their functionality for devices and applications. ...
Low noise pixel detectors based on gated geiger mode avalanche photodiodes
The gated operation is proposed as an effective method to reduce the noise in pixel detectors based on Geiger mode avalanche photodiodes. A prototype with the sensor and the front-end electronics monolithically integrated ...
