A real-time electrochemical sensing strategy for nicotine monitoring in smoke streams was developed using additively manufactured three-dimensional (3D) based on conductive polymer composites. Disc-type microelectrodes (...

In recent years, significant progress has been achieved in the design and fabrication of stretchable optoelectronic devices. In general, stretchability has been achieved through geometrical modifications of device compon...

Neurological disorders such as post-stroke hemiplegia, spinal cord injury, and Parkinson disease represent a major global health burden. Brain-computer interface (BCI), which creates direct communication pathways between...

ABSTRACT Patterned microstructure arrays are widely used in flexible electronics, optics, and biosensing, yet fabrication still relies on costly, process‐intensive methods (e.g., photolithography) with limited reconfig...

Abstract In previous work, we introduced an ‘invisible’ ECG system with electrodes integrated into a toilet seat, capturing signals from the thighs. Here, we present the tOLIet dataset with single-lead thigh ECGs to ...

Vertically aligned nanowire arrays, with high surface-to-volume ratio and efficient light-trapping absorption, have attracted much attention for photoelectric devices. In this paper, vertical β-Ga2O3 nanowire arrays wit...

Transparent conductive oxides (TCOs) are used in solar cells not only to extract photogenerated carriers but also to allow sunlight to reach the photoactive material. Therefore, controlling the electrical and optical pro...

It was found by scanning electron microscopy method that the ZrMn0.5Ni1.2Cr0.18А0.1 alloy has a dendritic structure, and the shooting of a typical section of the surface of the metalographic sample in characteristic rad...

In the course of the research it was determined that step-by-step air exposition of the Zr-Mn-Cr-Ni-V alloy (in the form of ingot and powder) facilitating the formation of concentration inhomogeneity significantly increa...

The work presents the results of a thermodynamic study of the Er-Te system by the method of electromotive forces (EMF) in the temperature range of 300-450 K. From the EMF measurements of the concentration cells relative ...

All-solution-processed flexible organic solar cells (FOSCs) with high power conversion efficiency (PCE) are the prerequisite for application in low-cost, large-area, flexible, photovoltaic devices. In this work, high-per...

"The water pollution due to emerging organic pollutants, such as agrochemicals, has become a topic of growing interest worldwide. The increase of pollutants in aquatic systems stimulated the development of new strategies...

Tunable metasurfaces can change the optical properties of incident light at will such as amplitude, phase, and polarization in a time-dependent fashion. Ultrafast switching speed and the ability for the pixel size reduct...

Abstract Vision-based robotic triaxial tactile sensing provides superior spatial resolution and rich multimodal data. However, employing rigid CMOS imagers suffers from limitations in mechanical flexibility and large-are...

The increasing emission of carbon dioxide (CO2) due to industrialization and deforestation has accelerated global climate change, requiring the development of new technologies for CO2 capture and utilization. This study ...

Evolution of fuel cells using metallic inorganic catalysts has led to the development of biofuel cells with potential applications in implantable devices. However, the main disadvantages in real world applications of enz...
