Development and characterization of TGF-β1 MIP electrochemical sensor as a tool for POC diagnostics.
Abstract In recent years, the exploitation of natural resources and industrial development have led to production harmful pollutants. Much these contaminants end up in water resources, reducing availability drinking water. Therefore, it is necessary find remedies this situation. Solutions could be adsorption or degradation through photocatalysis compounds. A good candidate for task titanium dioxide (TiO 2 ), due its non-toxicity, stability low cost. work, we propose a novel synthesis TiO...
Pillar-like structures of nanodiamonds on a silicon substrate are self-assembled for the first time by pulsed spray technique. This technique allows us to deposit nanodiamond layers using high quality nanocrystals 250 nm dispersed in 1,2-dichloroethane (DCE) solvent. The analysis 2D/3D confocal and atomic force microscopy images evidences presence pillar-like distributed an irregular way. proposed method is simple, easy cheap, does not require complex growth processes or structured...
A target irradiated with a high power laser pulse, blows off large amount of charge and as consequence the itself becomes generator electromagnetic pulses (EMP) owing to return current flowing ground through holder. The first measurement magnetic field induced by neutralizing reaching value few kA was performed use an inductive probe at PALS Laser Facility (Cikhardt et al. Rev. Sci. Instrum. 85 (2014) 103507). full description EMP generation should contain information on spatial distribution...
Nanodiamond (ND) layers on silicon substrate are deposited by the pulsed spray technique starting from nanoparticles of about 250 nm dispersed in 1,2-dichloroethane solvent. The aim this letter is to investigate quantum efficiency (QE) photocathodes based ND particles vacuum ultraviolet spectral range. Various examined employing as-received and hydrogenated nanoparticles. As expected, hydrogen plasma treatment improves strongly photoemission layer giving a QE 22% at 146 nm. Indeed, value...
This work investigates the physical properties of Al1−xScxN thin films sputtered at low temperatures by varying process conditions. Specifically, were deposited room temperature applying a radio frequency power equal to 150 W an AlSc alloy (60:40) target, nitrogen flux percentage in (Ar + N2) sputtering atmosphere (30%, 40%, 50%, and 60%) keeping constant working pressure 5 × 10−3 mbar. The structural chemical studied x-ray diffraction Rutherford backscattering spectrometry techniques,...
Abstract Time-of-flight spectra of C, Fe, and Si ions produced with the use a KrF excimer laser have been analyzed. Ion currents were collected by Faraday cups their responses analyzed using detector signal function. This function was derived from shifted Maxwell-Boltzmann velocity distribution, in order to uncover contribution partial all ionized species constituting expanding plasma plume. The deconvolution method allowed estimate parameters plasma, such as ion temperature center-of-mass...
Abstract A space-resolved charge density of ions is derived from a time-resolved current emitted laser-produced plasma and expanded into the vacuum along collision-free field-free paths. This derivation based on similarity relationship for ion currents with “frozen” charges observed at different distances target. makes it possible to determine map selected times after laser interaction signals time-of-flight detectors positioned certain distance target around target-surface normal. In this...
In this work, we present a new pulsed laser ablation technique to obtain energetic ion beams. The accelerator made is compact device able extract and accelerate the ionic components of plasma up 160 keV per charge state. It composed by generating chamber containing an expansion used like first electrode. Next, second electrode connected ground third negative voltage are used. also as Faraday cup. By analysis signals studied plume parameters such TOF accelerated signals, state, divergence.
The deposition of as‐received nanodiamond (ND) particles on silicon substrate was performed by the pulsed spray technique, using a dispersion 250 nm ND in 1,2‐dichloroethane. A set samples sprayed varying number pulses from 1 to 500. morphology characterized and monitored means optical, atomic force, confocal microscopies. At low pulses, sparse diamond were observed, whereas at high dense/quasi‐continuous layers formed. electrical conductivity measurements surface evidenced remarkable change...
Abstract In this work, two different techniques to modify polymeric surfaces are compared: laser irradiation and ion implantation. The treated polymers were samples of ultra high molecular weight polyethylene. treatment was performed by utilizing sources operating in the UV IR range applying many shots an air atmosphere. Ion implantation using a new source accelerator with accelerating voltage 40 kV. Contact angle, roughness Fourier transform infra red measurements carried out before after...
In this study, the evidence of electron-dense magnetic inclusions with polyhedral shape in cytoplasm Harveyi clade Vibrio strain PS1, a bioluminescent bacterium living symbiosis marine organisms, led us to investigate behavior under exposure static fields ranging between 20 and 2000 Gauss. When compared sham-exposed, light emission field-exposed bacteria growing on solid medium at 18°C ±0.1°C was increased up two-fold as function dose growth phase. Stimulation bioluminescence by field more...
