Abstract This paper describes the preparation, characterization, and electrochemical properties of reduced graphene sheet films (rGSFs), investigating especially their behavior for several redox systems electrocatalytic towards oxygen some small molecules. The sheets (rGSs) are produced in high yield by a soft chemistry route involving graphite oxidation, ultrasonic exfoliation, chemical reduction. Transmission electron microscopy (TEM), X‐ray diffraction (XRD), scanning (SEM), photoelectron...
An alkali-acitvated method was explored to synthesize activated carbon nanotubes (CNTs-A) with a high specific surface area (SSA), and large number of mesopores. The resulting CNTs-A were used as an adsorbent material for removal anionic cationic dyes in aqueous solutions. Experimental results indicated that have excellent adsorption capacity methyl orange (149 mg/g) methylene blue (399 mg/g). Alkali-activation treatment CNTs increased the SSA pore volume (PV), introduced oxygen-containing...
Here we report a graphene oxide amplified electrogenerated chemiluminescence (ECL) of quantum dots (QDs) platform and its efficient selective sensing for antioxidants. Graphene facilitated the CdTe QDs•+ production triggered O2•− generation. Then, high yield QDs* was formed due to combination O2•−, leading an ∼5-fold ECL amplification. Glutathione is most abundant cellular thiol-containing peptide, but intractable issue in analytical biochemical communities because detection interfered with...

Abstract Wearable tensile strain sensors have aroused substantial attention on account of their exciting applications in rebuilding tactile inputs human and intelligent robots. Conventional such devices, however, face the dilemma both sensitive response to pressure bending stimulations, poor breathability for wearing comfort.

A highly selective, sensitive, and low-cost hybrid sensing platform is developed based on extraordinary properties of explosives in an ionic liquid integrated electrochemical colorimetric approach.
E-textile consisting of natural fabrics has become a promising material to construct wearable sensors due its comfortability and breathability on the human body. However, reported fabric-based e-textile materials, such as graphene-treated cotton, silk, flax, generally suffer from electrical mechanical instability in long-term wearing. In particular, body have endure heat variation, moisture evaporation metabolic activities, even immersion with sweat. To face above challenges, here we report...
Abstract The rapid expansion of the fast fashion industry brings about environmental concerns such as dyestuffs-related water pollutions and waste textiles. Conventional wastewater-disposal strategies emphasize optimization photocatalytic activity to improve pollutant degradation efficiency, while absorptivity, recyclability sustainability photocatalysts are always ignored. overproduced textiles still in urgent being recycled reutilized eco-friendly approaches. In this work, a scalable...
Wearable electronics have promising applications in human–machine interfaces and Internet of Things. Recent reported wearable sensing techniques are implemented mainly by either encapsulated packaging approaches or deposition conductive nanomaterials onto flexible textiles. However, such fabrication technologies sacrifice the physical comfort, washability wettability which essential elements to wearables.

Plasmonic-based electrochemical impedance spectroscopy (P-EIS) is developed to investigate molecular binding on surfaces. Its basic principle relies the sensitive dependence of surface plasmon resonance (SPR) signal charge density, which modulated by applying an ac potential a SPR chip surface. The component response gives impedance, and dc provides conventional detection. plasmonic-based measured over range frequency in quantitative agreement with impedance.

Fluorescence photons emitted by single molecules contain rich information regarding their rotational motions, but adapting single-molecule localization microscopy (SMLM) to measure orientations and mobilities with high precision remains a challenge. Inspired dipole radiation patterns, we design implement Tri-spot point spread function (PSF) that simultaneously measures the three-dimensional orientation mobility of dipole-like emitters across large field view. We show measurements done using...
In soft matter, thermal energy causes molecules to continuously translate and rotate, even in crowded environments, thereby impacting the spatial organization function of most molecular assemblies, such as lipid membranes. Directly measuring orientation large collections (>3000 μm-2 ) single with nanoscale resolution remains elusive. this paper, we utilize SMOLM, single-molecule localization microscopy, directly measure spectra (3D plus "wobble") lipophilic probes transiently bound...
