Over the last few decades, a large number of pH sensitive materials with new compositions and structures have been proposed. Solid state sensors based on organic, inorganic composite are actively investigated, an increasing interest in performance offered by nano-scale materials. Our review provides thorough, up-to-date knowledge wide range measurement methods related sensing materials, firstly introducing well established for then, covering recent developments inorganic, organic...
A model consisting of an equation that includes graphene thickness distribution is used to calculate theoretical 002 X-ray diffraction (XRD) peak intensities. An analysis was performed upon samples produced by two different electrochemical procedures: electrolysis in aqueous electrolyte and molten salts, both using a nonstationary current regime. Herein, the enhanced partitioning corresponding 2θ interval, resulting significantly improved accuracy results. The curves obtained exhibit...
The subject of this study is chemical functionalization as means structural modification multiwalled carbon nanotubes.The main goal the experiments was to create highest density carboxyl groups on nanotubes surface, necessary for further nanocomposite application.Two different types (I: outer diameter d = 50 ÷ 100 nm, purity ≈84%, synthesized by pyrolysis and II: 10 40 ≈94%, vapor deposition) were treated concentrated nitric acid (HNO3) alkaline mixture (NH4OH+H2O2).The medium "milder" less...
There are several accepted methods used for X‐ray diffraction analysis on graphene layers and sample's stacking height L C . The Scherrer equation is avoided since the in samples non‐uniformly distributed therefore have non‐uniform thickness. Instead, a model that includes thickness distribution to calculate average number of then height. was performed 12 produced by high‐temperature electrolysis molten salts. Another method hence samples’ height, Raman spectra ‐peak position method. It...
Increased environmental pollution is becoming one of the greatest problem world facing nowadays causing irreparable damage to earth. Because their novel and tunable physicochemical properties, nano materials have attracted great attention among researchers as promising combat challenges. Developing nanotechnology triggered a deal interest in these structures for monitoring treatment, enabling new technologies identifying addressing problems. Even though achieving control challenging task...
The effect of using multiwalled carbon nanotubes (MWCNTs) vs. traditional materials (as e.g., Vulcan XC-72) as supports for mixed non-platinum catalysts hydrogen evolution was studied. Intrinsic changes in catalyst’s structure, surface and activity were registered. It found that MWCNTs significantly improve the a result (i) increase real area catalyst, (ii) improving electrical conductivity electrode, (iii) better dispersion active catalytic centers over electrode (iv) geometric nature...

The structural and electrocatalytic characteristics of composite materials based on non-precious metals were studied. Precursors metallic phase (Ni, Co or CoNi) oxide (TiO2) grafted a carbon substrate (Vulcan XC-72) by the sol-gel procedure thermally treated at 250 ?C. Ni CoNi crystals 10-20 nm produced, in contrast TiO2 amorphous. dissimilar electronic character components gives rise to significant activity for hydrogen evolution reaction (HER), even basic series prepared materials. Further...
