Thin Al films sputtered on n-silicon wafers were anodized in two potentiodynamic steps tartaric acid at and malonic to prepare nanoporous alumina templates of type A B, respectively. Processes the interface closely examined avoid field-assisted dissolution during anodizing. semiconductor layers radio-frequency magnetron onto as-anodized pore-widened templates. It was revealed that covered entire surface while only partly penetrating into widened pores B The crystallized , with monoclinic...
A non-invasive solution for monitoring of the activity and dehydration organisms is proposed in work. For this purpose, a wireless standalone chemical sensor platform using two separate measurement techniques has been developed. The first approach based on humidity measurement. Our uses new nanostructured TiO2 surface sweat rate monitoring. second technique potassium concentration urine. High level denotes clear occurrence dehydration. Furthermore, Wireless Body Area Network (WBAN) was...
The paper describes the important aspects of developed technology for manufacturing silicon-carbide substrates optical mirrors intended future use in space applications. It is shown that material with best combination thermophysical and mechanical properties (Maksutov’s criterion) among known analogs used making astronomical obtained. characteristics a mirror made lightweight substrate diameter 205 mm are described, compared parameters most silicon carbide various missions as proto types....
Dehydration of human organism is an issue in case fitness activity and elderly people. We have designed the solution for noninvasive continuous monitoring which way determination body dehydration. This system based on measurements relative humidity near skin to calculate water release through skin, actual weight, potassium ions concentration urea, a basic component urine.
Portable system for monitoring of excreted fluid through the skin during human activity has been developed and fabricated.The consists sensing element that is mounted close to open surface transmits information about relative humidity levels temperature wireless communication coordinator unit acquisition point which equipped by analyzing software performing calculation surface.A special utility designed data storage user control main measured stored parameters.Obtained collected in time...
The results of studies on the production a porous ceramic-matrix composite material C–N/SiC from silicon carbide and nitrogen-doped nanostructured carbon for subsequent use as supercapacitor electrodes are presented. is formed by pressing micropowder (1 µm) impregnating with solution carbamide (nitrogen source) in phenol-formaldehyde varnish (carbon source), curing pyrolysis nitrogen atmosphere. maximum concentration was obtained (16 wt.%) at 50 ºС viscosity 134.3 mPa⋅s. Thermogravimetric...
This work shows the preliminary results concerning to synthesis or modification of carbon-based nanomaterials by plasma discharge, magnetron sputtering, and chemical vapor deposition methodologies. As a first approach show potential these techniques, scanning electron microscopy analysis was performed in order verify morphological changes proof that it is possible design morphology doped decorated carbon nanomaterials. In spite none further characterization performed, from discussion...
Abstract High productive machining of C/SiC preceramics is investigated in relation to the fabrication complex‐shaped reaction‐bonded silicon carbide ceramics. Machinability analyzed at different manufacturing steps ceramics preparation. Machining after carbonization step shown be most efficient. Great value material removal rate 360 mm 3 /s achieved by high CNC‐milling carbonized a feed 50 mm/s without any defects upon processed surfaces, edges, and corners. Diamond tool wears approximately...
This paper will be focused on the development of anew non-invasive and non-obtrusive medical wireless wearable system which is primarily used for dehydration detection but can easily adapted to measurement other values. real time telemonitoring elderly people, diabetics sportsmen during their normal life in this version. There are many devices shown fig. 1. The basis formed by groups sensors contain body (temperature, humidity trans-epidermal water-loss detector [1]), ambient (urea potassium...
