Contact lenses have become a popular health-monitoring wearable device due to their direct contact with the eyes. By integrating biosensors into lenses, real-time and noninvasive diagnoses of various diseases can be realized. However, current lens sensors often require complex electronics, which may obstruct user's vision or even damage cornea. Moreover, most reported only detect one analyte. Therefore, an optical-based dual-functional smart sensor has been introduced monitor intraocular...
MXene based composite conductive aerogels have been extensively investigated as sensitive materials for wearable pressure sensors owing to their effective 3D network microstructures and the excellent conductivity of MXene. In this work, we fabricated a porous Ti3C2Tx MXene/poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) aerogel (MPCA) with controllable patterning property utilizing Cu-assisted electrogelation method.

Cubic In2O3 (bcc-In2O3) was transformed into a mixture of bcc-In2O3 and rhombohedral (rh-In2O3) by Zn doping. The Zn-doped flower-like structures consisted many thin sheets with length 0.4–1 μm, cubes 200 nm, while the size microflowers 1–3.5 μm. doping concentration significantly affected phase transformation overall morphology In2O3. Furthermore, analysis N2 adsorption–desorption measurements showed that (sample S5) adsorbed largest amount had biggest surface area (46.41 m2 g−1), which...

Perovskite solar cells (PVSCs) have attracted extensive studies due to their high power conversion efficiency (PCE) with low-cost in both raw material and processes. However, there remain obstacles that hinder the way commercialization. Among many drawbacks PVSCs, we note problems brought by use of noble metal counter electrodes (CEs) such as gold silver. The costly Au Ag need energy-consumption thermal evaporation process which can be made only expensive equipment under vacuum. All factors...

The limited intrinsic conductivity of two-dimensional (2D) MoS₂ nanosheets compromises its high electrocatalytic performance. In this work, we develop a facile method simply dispersing into water-isopropanol solution high-conducting single-walled carbon nanotubes (SWCNTs) for preparation MoS₂/SWCNT composites. SWCNTs in the hybrid system serve as effective electron transport channels among 2D and facilitate charge transfer at catalyst-electrolyte interface. We investigated influence ratios...
