2024 - English
Neuromorphic engineering is a rapidly developing branch of science that aims to implement the unique attributes of biological neural networks in artificial devices. Most neuromorphic devices are based on the resistive switching effect, which involves changing the device’s conductivity in response to an external electric field. For instance, percolating nanoparticle (NP) networks produced by gas aggregation cluster sources (GAS) show collective spiking behavior in conductivity reminiscent of brain-like dynamics. Nevertheless, the problem of dynamic spatial reconfiguration in solid-state neuromorphic systems remains unsolved. Herein, novel nanofluids with resistive switching properties are proposed as neuromorphic media. They are produced by depositing silver NPs from GAS into vacuum-compatible liquids (paraffin, silicon oil, and PEG) without the use of surfactants or other chemicals. When the electric field is applied between two electrodes, the migration of NPs toward biased electrode is detected in all liquids. The electrophoretic nature of the NP movement was proved by means of ζ-potential measurements. Such movement led to the self-assembly of NPs in conductive paths connecting the electrodes and, as a result, to resistive switching. The electrical response was strongly dependent on the dielectric constant of the base liquid. The Ag-PEG nanofluid demonstrated the best switching performance reproducible during several tens of current-voltage cycles. The growth of flexible and reconfigurable conductive filaments in nanofluids makes them suitable media for potential realization of 3D neural networks.

Vliv biodegradabilní polyuretanové pěny na biocenózu a kalovou aktivitu v reaktorech simulující provoz domácích ČOV
Skleničková, Kateřina; Říhová Ambrožová, J.; Pečenka, M.; Halecký, M.; Beneš, Hynek
2022 - Czech
Byla navržena a připravena hydrofilní a plně alifatická biodegradabilní polyuretanová (PUR) pěna s otevřenou buněčnou strukturou, která byla následně použita jako nosič biofilmu a zdroj živin v reaktoru simulující domácí čistírnu odpadních vod. Na základě chemických, hydrobiologických analýz, vývoje mikroorganismů a enzymatických aktivit bylo zjištěno, že PUR pěna může úspěšně sloužit jako nosič pro mikroorganismy aktivovaného kalu a zároveň může být jimi postupně biodegradována při omezeném přísunu výživy aktivovaného kalu. Hydrophilic and fully aliphatic polyurethane (PUR) foam exhibiting a highly open cellular structure was used as a biodegradable biofilm carrier that would serve simultaneously as a nutrient source. A one-month laboratory testing in a reactor simulating domestic wastewater treatment plants was conducted based on chemical and hydrobiological analyses as well as evaluation of microorganism development and enzymatic activity. It was found that PUR foam can successfully serve as a carrier for microorganisms and simultaneously can be biodegraded when the supply of nutrition is limited. Keywords: polyurethane foam; biofilm carriers; wastewater Available at various institutes of the ASCR

Degradation of polycaprolactone electrospun materials - methods of analysis
Havlíčková, K.; Řezanka, M.; Kobera, Libor; Kuželová Košťáková, E.; Lukáš, D.; Jenčová, V.
2021 - English
Biodegradable electrospun materials are widely used for medical application. Polycaprolatone is polymer suitable for electrospinning technology and is very often used to create nanofibrous scaffolds for tissue engineering. The time to disintegration or biodegradation of such materials is very important here. However, testing is not entirely easy. It is not possible to create exactly body-like conditions in vitro. Moreover, it is not easy to find suitable analytical methods that would show exactly what happens in the nanofibrous polycaprolactone electrospun samples at certain stages of degradation, ie how the internal structure of decaying nanofibers changes. This paper describes the traditional use of methods for testing polycaprolatone nanofibers by enzymatically catalysed degradation. Morphological changes are studied using scanning electron microscope images. However, it also offers a non-traditional analysis of polycaprolactone electrospun materials using the ssNMR method. Keywords: electrospinning; nanofibers; enzymatic degradation Available at various institutes of the ASCR
