In this study, we have demonstrated the fabrication of novel materials called boron-doped carbon nanowalls (B:CNWs), which are characterized by remarkable electrochemical properties such as high standard rate constant (k°), low peak-to-peak separation value (ΔE) for oxidation and reduction processes [Fe(CN)6]3-/4- redox system, surface resistivity. The B:CNW samples were deposited microwave plasma-assisted chemical vapor deposition (CVD) using a gas mixture H2/CH4/B2H6 N2. Growth results in...
The variable configuration of Raman spectroscopic platforms is one the major obstacles in establishing spectroscopy as a valuable physicochemical method within real-world scenarios such clinical diagnostics. For real world applications like diagnostic classification, models should ideally be usable to predict data from different setups. Whether it done by training rugged model with many setups or primary-replica strategy where are developed on 'primary' setup and test generated 'replicate'...
Algorithms of Chemicals Detection Using Raman Spectra spectrometers are devices which enable fast and non-contact identification examined chemicals. These utilize the phenomenon to identify unknown often illicit chemicals ( e.g. drugs, explosives) without necessity their preparation. Now, can be portable therefore more widely used improve security at public places. Unfortunately, spectra measurements is a challenge due noise interferences present outside laboratories. The design spectrometer...
Portable Raman spectrometer - design rules and applications spectroscopy has become more popular due to its new prospective field in forensic sciences, war against terrorism, environment protection other chemical analysis. spectrometers can be miniaturised portable devices their price is decreasing development of optoelectronics components. Unfortunately, this technology still numerous limitations that influence limit the scope possible applications. The conception described, including...
Abstract An electrochemical oxidation using a highly boron‐doped diamond (BDD) electrode has been tested for the treatment of solutions containing ionic liquids (ILs). The double‐sided Si/highly BDD electrodes were synthesized by microwave plasma enhanced chemical vapour deposition (MW PE CVD). Investigation surface with scanning electron microscopy (SEM) confirmed that layers continuous and formed densely packed grain structure. structure was Raman spectra analysis. effect IL as kind...
Nucleation and growth processes of thin diamond films on fused silica optical fibres have been investigated. Fibres were coated with film using microwave plasma enhanced chemical vapour deposition (µPE CVD) system. Since the glass requires high seeding density, two types pre‐treatment applied: titanium dioxide (TiO 2 ) interlayer sonication in nanodiamond suspension. In experiment, (∼20 nm) TiO deposited high‐power impulse magnetron sputtering. Subsequently, a set up to 60 min‐long process...
In this paper low-coherence fibre-optic sensors based on the Fabry-Perot and Michelson interferometer, which were designed elaborated at our laboratory, are shown.We present results of investigation working in both configurations.These allowed us to compare properties configurations.The theoretical analysis experimental made possible select best construction, was implemented refractive index.

Preclinical research of biomedical optoelectronic devices is often performed with the use blood phantoms — a simplified physical model blood. The aim this study comparison and distinction between as well whole human measurements. We show how such may influence incorrect interpretation measured signal. On other hand, we highlight enables to investigate phenomena that otherwise are almost impossible be noticed.
