Low-cost fabrication of zero-power metal oxide nanowire gas sensors: trends and challenges
Self-heating of metal oxide nanowires when a measuring current flows through them allows simultaneously heating the metal oxide, which is required for correct gas sensing operation, and measuring the nanowire resistance ...
Quantification of interacting cognate odorants with olfactory receptors in nanovesicles
This study aims to improve our understanding of the interaction between olfactory receptors and odorants to develop highly selective biosensing devices. Natural nanovesicles (NVs) from Saccharomyces cerevisiae, ~100 nm in ...
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 ...
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 ...
Search for Hidden-Sector Bosons in B0→K*0μ+μ− Decays
A search is presented for hidden-sector bosons, χ , produced in the decay B 0 → K ∗ ( 892 ) 0 χ , with K ∗ ( 892 ) 0 → K + π − and χ → μ + μ − . The search is performed using p p -collision data corresponding to 3.0 ...
Role of Ethanolamine on the Stability of a Sol-Gel ZnO ink
This work presents a detailed structural and chemical characterization of the system formed by zinc acetate dihydrate (ZAD) and ethanolamine (EA) with methoxyethanol (ME), in order to describe its stability. The origin of ...
Development of a novel automatable fabrication method based on electrospinning co electrospraying for rotator cuff augmentation patches
Rotator cuff tear is one of the most common shoulder diseases. Rotator cuff augmentation (RCA) is trying to solve the high retear failure percentage after the surgery procedures (20-90%). The ideal augmentation patch must ...
Measurement of the CP-Violating Phase ϕs in the Decay B0s→J/ψϕ
We present a measurement of the time-dependent C P -violating asymmetry in B 0 s → J / ψ ϕ decays, using data collected with the LHCb detector at the LHC. The decay time distribution of B 0 s → J / ψ ϕ is characterized by ...
Semiclassical theory of shot noise in ballistic n+in+ semiconductor structures: relevance of Pauli and long range Coulomb interactions
We work out a semiclassical theory of shot noise in ballistic n+-i-n+ semiconductor structures aiming at studying two fundamental physical correlations coming from Pauli exclusion principle and long-range Coulomb interaction. ...

Time resolution and radiation tolerance of depleted CMOS sensors
Depleted Monolithic Active Pixel Sensors (DMAPS), also known as depleted CMOS sensors, are extremely attractive for particle physics experiments. As the sensing diode and readout electronics can be integrated on the same ...
Site-specific growth and in situ integration of different nanowire material networks on a single chip: towards a nanowire-based electronic nose for gas detection
A new method for the site-selective synthesis of nanowires has been developed to enable material growth with defined morphology and at the same time different composition on the same chip surface. The chemical vapour ...
