White luminescence from Si+ and C+ ion-implanted SiO2 films
The microstructural and optical analysis of SiO2 layers emitting white luminescence is reported. These structures have been synthesized by sequential Si+ and C+ ion implantation and high-temperature annealing. Their white ...
Raman microstructural analysis of silicon-on-insulator formed by high dose oxygen ion implantation: As-implanted structures
A microstructural analysis of silicon-on-insulator samples obtained by high dose oxygen ion implantation was performed by Raman scattering. The samples analyzed were obtained under different conditions thus leading to ...
Multiwavelength excitation Raman scattering analysis of bulk and 2 dimensional MoS2: vibrational properties of atomically thin MoS2 layers
In order to deepen the knowledge of the vibrational properties of two-dimensional (2D) MoS2 atomic layers, a complete and systematic Raman scattering analysis has been performed using both bulk single-crystal MoS2 samples ...
Sociodemographic, clinical, and immunological factors associated with SARS-CoV-2 diagnosis and severe COVID-19 outcomes in people living with HIV: a retrospective cohort study.
Background: Factors affecting outcomes of SARS-CoV-2 infection in people living with HIV are unclear. We assessed the factors associated with SARS-CoV-2 diagnosis and severe outcomes among people living with HIV. Methods: ...
Measurement of Bs0 and Ds- meson lifetimes
We report on a measurement of the flavor-specific Bs0 lifetime and of the Ds- lifetime using proton-proton collisions at center-of-mass energies of 7 and 8 TeV, collected by the LHCb experiment and corresponding to 3.0 ...
Search for the Decays Bs0→τ+τ- and B0→τ+τ-
A search for the rare decays Bs0→τ+τ- and B0→τ+τ- is performed using proton-proton collision data collected with the LHCb detector. The data sample corresponds to an integrated luminosity of 3 fb-1 collected in 2011 and ...
Electron energy-loss spectroscopic tomography of FexCo(3-x)O4 impregnated Co3O4 mesoporous particles: unraveling the chemical information in three dimensions
Electron energy-loss spectroscopy-spectrum image (EELS-SI) tomography is a powerful tool to investigate the three dimensional chemical configuration in nanostructures. Here, we demonstrate, for the first time, the possibility ...
Revealing Fast Cu-Ion Transport and Enhanced Conductivity at the CuInP2S6-In4/3P2S6 Heterointerface
Van der Waals layered ferroelectrics, such as CuInP2S6 (CIPS), offer a versatile platform for miniaturization of ferroelectric device technology. Control of the targeted composition and kinetics of CIPS synthesis, enables ...
A time-domain method for the analysis of thermal impedance response preserving the convolution form
The study of the thermal behavior of complex packages as multichip modules (MCM¿s) is usually carried out by measuring the so-called thermal impedance response, that is: the transient temperature after a power step. From ...
Wireless monitoring of the pH, NH4+ and temperature in a fish farm
In this paper, we present a practical application for wireless sensor networks (WSN): The sensing of the pH, NH4+ and temperature for a fish farm. Two different kinds of modules were designed: Te sensor and the wireless ...
Development of an ImmunoFET for Analysis of Tumour Necrosis Factor- (alfa) in Artificial Saliva: Application for Heart Failure Monitoring
Assessing tumour necrosis factor-(alfa) (TNF-(alfa)) levels in the human body has become an essential tool to recognize heart failure (HF). In this work, label-free, rapid, easy to use ImmunoFET based on an ion-sensitive ...
First observation of the decays ¯¯¯B0(s)→D+sK−π+π− and ¯¯¯B0s→Ds1(2536)+π−
The first observation of the decays ¯¯¯ B 0 s → D + s K − π + π − and ¯¯¯ B 0 → D + s K − π + π − are reported using an integrated luminosity of 1.0 fb − 1 recorded by the LHCb experiment. The branching fractions, ...
Determination of the Sign of the Decay Width Difference in the B0s System
The interference between the K + K − S -wave and P -wave amplitudes in B 0 s → J / ψ K + K − decays with the K + K − pairs in the region around the ϕ ( 1020 ) resonance is used to determine the variation of the difference ...
Engineered Macroscale Cardiac Constructs Elicit Human Myocardial Tissue-like Functionality
In vitro surrogate models of human cardiac tissue hold great promise in disease modeling, cardiotoxicity testing, and future applications in regenerative medicine. However, the generation of engineered human cardiac ...
Dynamic photopolymerization produces complex microstructures on hydrogels in a moldless approach to generate a 3D intestinal tissue model
Epithelial tissues contain three-dimensional (3D) complex microtopographies that are essential for proper performance. These microstructures provide cells with the physicochemical cues needed to guide their self-organization ...
A Feedfordward Adaptive Controller to Reduce the Imaging Time of Large-Sized Biological Samples with a SPM-Based Multiprobe Station
The time required to image large samples is an important limiting factor in SPM-based systems. In multiprobe setups, especially when working with biological samples, this drawback can make impossible to conduct certain ...
The proangiogenic potential of a novel calcium releasing biomaterial: Impact on cell recruitment
In current bone tissue engineering approaches the achievement of sufficient angiogenesis, during tissue regeneration, is a major limitation in order to attain full tissue functionality. Recently, our group has found that ...
Drift compensation of gas sensor array data by Orthogonal Signal Correction
Drift is an important issue that impairs the reliability of gas sensing systems. Sensor aging, memory effects and environmental disturbances produce shifts in sensor responses that make initial statistical models for gas ...
ICAM-1 Targeting of Nanocarriers in a Human Blood-Brain-Barrier-on-a-Chip Complements In Vivo Brain Delivery Observations
Targeting therapeutic nanocarriers (NCs) to endothelial receptors favours transport across the blood-brain barrier (BBB), a main obstacle to access the brain. While these strategies compel validation in animals, quantitative ...
A microfluidic neuronal platform for neuron axotomy and controlled regenerative studies
Understanding the basic mechanisms of neural regeneration after injury is a pre-requisite for developing appropriate treatments. Traditional approaches to model axonal lesions, such as high intensity power laser ablation ...
