“…To grow ZnO NRs layer over the chip we followed a few-step process according to hydrothermal technology (Figure 1) in frames of earlier established protocols [53,54]. All the chemicals used for synthesis were supplied at high purity grade (Vekton).…”

We discuss the fabrication of gas-analytical multisensor arrays based on ZnO nanorods grown via a hydrothermal route directly on a multielectrode chip. The protocol to deposit the nanorods over the chip includes the primary formation of ZnO nano-clusters over the surface and secondly the oxide hydrothermal growth in a solution that facilitates the appearance of ZnO nanorods in the high aspect ratio which comprise a network. We have tested the proof-of-concept prototype of the ZnO nanorod network-based chip heated up to 400 °C versus three alcohol vapors, ethanol, isopropanol and butanol, at approx. 0.2–5 ppm concentrations when mixed with dry air. The results indicate that the developed chip is highly sensitive to these analytes with a detection limit down to the sub-ppm range. Due to the pristine differences in ZnO nanorod network density the chip yields a vector signal which enables the discrimination of various alcohols at a reasonable degree via processing by linear discriminant analysis even at a sub-ppm concentration range suitable for practical applications.

“…Nanostructures formation was carried out via mild hydrothermal synthesis [14][15][16][17] at the low temperature (Т=85°С) within 60 min. 25 mM hexamethylene tetramine was used as a weak alkali, while zinc nitrate equimolar solution Zn(NO 3 ) 2 was a Zn 2+ precursor.…”

In this work, the ZnO-based materials were synthesized for gas sensors applications. The nanostructures formation was carried out by mild hydrothermal synthesis with the variations in surfactant concentration. The qualitative and quantitative analysis of the surface states in ZnO nanocrystals was performed. The effect of surfactant (cysteine) adsorption on ZnO 1D-nanostructures growth and the distribution of acid-bade adsorption sites on nanostructures surface were investigated. The control of the nanorods aspect ratio (about 0.4 at cystein concentration of 5 mM/l) leads to the changes in the Zn 2+ /O 2ions proportion, emerging on the surface. High cysteine concentrations resulted in the formation of Brönsted acid and Lewis base adsorption sites.

“…Cadet-M has a carbon fiber float housing for lightweight construction [6]. To increase the operating time, heterostructured solar panels [6,7,8,9,10] on a silicon substrate with high efficiency were used as well as a battery management system (BMS) [11,12], which allows autonomous monitoring of up to two days. The platform is equipped with sonar, a water sampling system, a radiation sensor, a robot arm, a radar and other instruments and devices.…”

Environmental monitoring has become an urgent task in recent years in connection with the deterioration of the environmental situation caused by industrialization [1]. Usually, manned vessels with measuring equipment and personnel serving it on board were used for these purposes, but with the development of technology, full automation of this process became possible. The problem of the need to use human resources is solved by applying an autonomous vessel control system. However, the big problem remains, which is the need to refuel the vessel in connection with the finite amount of stored energy. This problem is solved by using renewable energy, an example of which is solar energy, on measuring platforms. This article will discuss methods for developing platforms controlled by the autopilot and using solar energy, using the Cadet-M platform as an example.
