Color QR Codes for Smartphone-Based Analysis of Free Chlorine in Drinking Water
Free chlorine (FC) plays a crucial role in ensuring the safety of drinking water by effectively inactivating pathogenic microorganisms. However, traditional methods for measuring FC levels often require specialized equipment ...
Area-Efficient Mixed-Signal Time-to-Digital Converter Integration for Time-Resolved Photon Counting
Digital histogram generation for time-resolved measurements with single-photon avalanche diode (SPAD) sensors requires the storage of many timestamp signals. This work presents a mixed-signal time-to-digital converter (TDC) ...

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 ...
Microwave oscillator and frequency comb in a silicon optomechanical cavity with a full phononic bandgap
Cavity optomechanics has recently emerged as a new paradigm enabling the manipulation of mechanical motion via optical fields tightly confined in deformable cavities. When driving an optomechanical (OM) crystal cavity with ...
A current-mode interface circuit for a piezoresistive pressure sensor
An interfacing circuit for piezoresistive pressure sensors based on CMOS current conveyors is presented. The main advantages of the proposed interfacing circuit include the use of a single piezoresistor, the capability of ...
Double stent-retriever as the first-line approach in mechanical thrombectomy: a randomized in vitro evaluation
Background A repeated number of passes during mechanical thrombectomy leads to worse clinical outcomes in acute ischemic stroke. Initial experiences with the simultaneous double stent-retriever (double-SR) technique as the ...
Avoiding sensor blindness in Geiger mode avalanche photodiode arrays fabricated in a conventional CMOS process
The need to move forward in the knowledge of the subatomic world has stimulated the development of new particle colliders. However, the objectives of the next generation of colliders sets unprecedented challenges to the ...
Fuzzy k-NN applied to mould detection
The possibility to detect Aspergillus versicolor growing on different building materials by a metal oxide sensor array is studied. Results show that an accurate classification rate of 89 ± 3% can be obtained combining an ...
Combining non selective gas sensors on a mobile robot for identification and mapping of multiple chemical compounds
In this paper, we address the task of gas distribution modeling in scenarios where multiple heterogeneous compounds are present. Gas distribution modeling is particularly useful in emission monitoring applications where ...
Anomalous optical and electrical recovery process of photoquenched EL2 defect produced by oxygen and boron ion implantation in gallium arsenide
The optical and electrical recovery processes of the metastable state of the EL2 defect artificially created in n‐type GaAs by boron or oxygen implantation are analyzed at 80 K using optical isothermal transient spectroscopy. ...
Boron-incorporating silicon nanocrystals embedded in SiO2: absende of free carriers vs. B-induced defects
Boron (B) doping of silicon nanocrystals requires the incorporation of a B-atom on a lattice site of the quantum dot and its ionization at room temperature. In case of successful B-doping the majority carriers (holes) ...
Intense green-yellow electroluminescence from Tb+-implanted silicon-rich silicon nitride/oxide light emitting devices
High optical power density of 0.5 mW/cm2, external quantum efficiency of 0.1%, and population inversion of 7% are reported from Tb+-implanted silicon-rich silicon nitride/oxide light emitting devices. Electrical and ...
Enhanced photoelectrochemical behavior of H-TiO2 nanorods hydrogenated by controlled and local rapid thermal annealing
Recently, colored H-doped TiO2 (H-TiO2) has demonstrated enhanced photoelectrochemical (PEC) performance due to its unique crystalline core disordered shell nanostructures and consequent enhanced conduction behaviors between ...
Nanoscale electrical conductivity of the purple membrane monolayer
Nanoscale electron transport through the purple membrane monolayer, a two-dimensional crystal lattice of the transmembrane protein bacteriorhodopsin, is studied by conductive atomic force microscopy. We demonstrate that ...
Tailoring the surface density of silicon nanocrystals embedded in SiOx single layers
