“…The 3D-porous structure and excellent permeability of the AgNPs-pSBS fiber are very advantageous for many wearable electronic devices. For example, when applied for sensing body secretions or environmental humidity, they can enhance the active surface area of devices and afford efficient transportation of the analyte to improve their sensing and detecting performance. − …”

Elastic fiber conductors are advantageous for applications in wearable electronics due to their small size, light weight, and excellent integration ability. Here, we report the fabrication of elastic fiber conductors with a three-dimensional (3D) porous structure using electrospun thermoplastic elastomer (TPE) microfibers and silver nanoparticles (AgNPs) as the building blocks. With the 3D porous structure, such a fiber is highly permeable to gases and liquids. As such, the performance of the fiber in many applications of wearable electronics (especially wearable sensors and detectors) can be improved significantly. Benefitting from the excellent processability of TPE and dispersibility of AgNPs, the fiber is highly compatible with thermal and solvent welding. In addition, the fiber also possesses super stretchability, high conductivity, and robust endurance to deformation. As a proof-of-concept application, we demonstrate that a ropeshaped capacitor made by plying one pair of such fibers can detect the volume change of artificial sweat with 17-times higher sensitivity than the capacitor using nonporous fibers as electrodes. We further demonstrate that, by integrating two groups of perpendicularly arranged fibers into a monolithic porous mat, sensitive matrix-addressed monitoring of artificial sweat can be realized.

“…[11] Therefore, the presence of a band gap in the van der Waals semiconductors makes them appropriate for applications, such as photocatalysis, [12,13] optoelectronic devices, [14][15][16][17] photovoltaics, [18] and gas sensing. [19,20] In particular, Se-terminated metal chalcogenides exhibit superior chemical stability with respect to the parental Te-terminated compounds, [21][22][23][24] usually affected by faster oxidation with the inevitable formation of a sub-nanometric skin of tellurium oxide.…”

Here, we discuss the physicochemical properties of both bulk and nanosheets of III-VI and IV-VI metal chalcogenides and their application capabilities in electrocatalysis, photocatalysis, and gas sensing by combining density function theory with surface-science experiments. In particular, GaSe, InSe, and GeSe are van der Waals semiconductors stable in water media and robust against CO poisoning, which make them suitable candidates for application as low-cost (photo)catalysts in liquid media. Both bulk and exfoliated III-VI and IV-VI metal chalcogenides are prone to oxidation, with the formation of an oxide skin in oxidative environments. The self-assembled heterostructure formed by the oxide skin and the underlying bulk of metal chalcogenides makes the Heyrovsky step of HER energeti-cally favourable. Both metal and Se vacancies are necessary to decrease the energy barrier for HER in acid media. The oxidation modified the band gap, enabling the activation of photocatalytic process with different wavelengths. Moreover, the self-assembled metal-oxide/metal-chalcogenide heterostructure also enables sensing of NO 2 , NH 3 and CO for an operational temperature up to 600 °C. Thus, III-VI and IV-VI semiconductors represent a suitable platform for electrochemistry, photocatalysis, and chemical sensing, owing to their low costs as raw materials and the superior application capabilities activated just exploiting the natural interaction with air, which is beneficial for improving the (photo)electrocatalyst activity and the gas-sensing performances.

By means of theory and experiments, the application capability of nickel ditelluride (NiTe 2 ) transition-metal dichalcogenide in catalysis and nanoelectronics is assessed. The Te surface termination forms a TeO 2 skin in an oxygen environment. In ambient atmosphere, passivation is achieved in less than 30 min with the TeO 2 skin having a thickness of about 7 Å. NiTe 2 shows outstanding tolerance to CO exposure and stability in water environment, with subsequent good performance in both hydrogen and oxygen evolution reactions. NiTe 2 -based devices consistently demonstrate superb ambient stability over a timescale as long as one month. Specifically, NiTe 2 has been implemented in a device that exhibits both superior performance and environmental stability at frequencies above 40 GHz, with possible applications as a receiver beyond the cutoff frequency of a nanotransistor.
