Multioxide combinatorial libraries: fusing synthetic approaches and additive technologies for highly orthogonal electronic noses.

This study evaluates the performance advancement of electronic noses, on-chip engineered multisensor systems, exploiting a combinatorial approach. We analyze a spectrum of metal oxide semiconductor materials produced by individual methods of liquid-phase synthesis and a combination of chemical deposition and sol-gel methods with hydrothermal treatment. These methods are demonstrated to enable obtaining a fairly wide range of nanomaterials that differ significantly in chemical composition, crystal structure, and morphological features.

[Influence of lactoferrin and enzymatiс hydrolysates of cow's and mare's milk proteins on anaphylactic sensitivity and cytokine profile of rats].

The development of innovative ingredients of specialized formula for children with intolerance to cow's milk proteins requires accounting the influence of the protein component on the allergic sensitivity. of the research was to study the effect of lactoferrin (LF) from cow colostrum, cow's milk protein hydrolysate (CMPH) and mare's milk protein hydrolysate (MMPH) on the severity of the systemic anaphylaxis reaction, the levels of specific IgG antibodies and cytokines in rats parenterally sensitized with ovalbumin (OVA). .

Problems of human spermatozoa cryopreservation: research methods, solutions.

Cryopreservation of male gametes is one of the most important methods of assisted reproductive technologies, which allows preserving gametes for research or further use. However, the fertilizing ability of spermatozoa after cryopreservation decreases by 30-70%, which makes it urgent to search for new substances with cryoprotective properties. The review considers the main causes of cell damage during cryopreservation.

Current Trends and Promising Electrode Materials in Micro-Supercapacitor Printing.

The development of scientific and technological foundations for the creation of high-performance energy storage devices is becoming increasingly important due to the rapid development of microelectronics, including flexible and wearable microelectronics. Supercapacitors are indispensable devices for the power supply of systems requiring high power, high charging-discharging rates, cyclic stability, and long service life and a wide range of operating temperatures (from -40 to 70 °C). The use of printing technologies gives an opportunity to move the production of such devices to a new level due to the possibility of the automated formation of micro-supercapacitors (including flexible, stretchable, wearable) with the required type of geometric implementation, to reduce time and labour costs for their creation, and to expand the prospects of their commercialization and widespread use.

Oxidation of Ceramic Materials Based on HfB-SiC under the Influence of Supersonic CO Jets and Additional Laser Heating.

The features of oxidation of ultra-high-temperature ceramic material HfB-30 vol.%SiC modified with 1 vol.% graphene as a result of supersonic flow of dissociated CO (generated with the use of high-frequency induction plasmatron), as well as under the influence of combined heating by high-speed CO jets and ytterbium laser radiation, were studied for the first time.
