Using linear support vector machines, we investigated the feature selection problem for the application of all-against-all classification of a set of 20 chemicals using two types of sensors, classical doped tin oxide and zeolite-coated chromium titanium oxide sensors. We defined a simple set of possible features, namely the identity of the sensors and the sampling times and tested all possible ...

Copper oxide (Cu2O)-based heterojunction solar cells were fabricated by spin-coating and electrodeposition methods, and photovoltaic properties and microstructures were investigated. Zinc oxide (ZnO) and Cu2O were used as nand p-type semiconductors, respectively, to fabricate photovoltaic devices based on In-doped tin oxide/ZnO/Cu2O/Au heterojunction structures. Short-circuit current and fill f...

We present optical in situ investigations of lithium-ion dynamics lithium iron phosphate based positive electrodes. The change reflectivity these cathodes during charge and discharge is used to estimate apparent diffusion coefficients for the lithiation delithiation process entire electrode. Thereby, a scaling analysis transport applied, which clearly reveals its diffusive character. Results ar...

Aluminum-doped zinc oxide (ZnO:Al) [AZO] is a good candidate to be used as a transparent conducting oxide [TCO]. For solar cells having a hydrogenated amorphous silicon carbide [a-SiC:H] or hydrogenated amorphous silicon [a-Si:H] window layer, the use of the AZO as TCO results in a deterioration of fill factor [FF], so fluorine-doped tin oxide (Sn02:F) [FTO] is usually preferred as a TCO. In th...

Wide bandgap semiconducting oxides are emerging as potential 2D materials for transparent electronics and optoelectronics. This fuels the quest discovering new metal with ultrahigh transparency high mobility. While former can be achieved by reducing thickness of oxide films to only a few nanometers, latter is more commonly realized intentional doping. article reports one-step synthesis few-unit...

Background: Gas sensors are very important in several fields like gas monitoring, safety and environmental applications. In this approach, a new gas sensing concept is investigated which combines the powerful adsorption probability of metal oxide conductive sensors (MOS) with an optical ellipsometric readout. This concept shows promising results to solve the problems of cross sensitivity of the...

In this Letter, a dynamically tunable metasurface, which is based on antimony trisulfide, introduced. structure, first metal-insulator-metal (MIM) nanocavity optimized in way that, upon phase change, the visible response switches from transmissive colored window into reflective mirror. Later, an indium tin oxide nanoantenna integrated MIM cavity to provide antireflection short-wave infrared (SW...

Reducing the noble-metal catalyst content of acid Polymer Electrolyte Membrane (PEM) water electrolyzers without compromising catalytic activity and stability is a goal of fundamental scientific interest and substantial technical importance for cost-effective hydrogen-based energy storage. This study presents nanostructured iridium nanodendrites (Ir-ND) supported on antimony doped tin oxide (AT...
