Organic liquid separation is currently an important but troublesome issue, which closely related to resource recycling and environmental protection. Here we reported a wettability-tunable nanofibrous membrane that can be used for efficient separation of wide ranges of immiscible organic liquid mixtures.
Novel fluorescent Ag nanoclusters are prepared based on an etching method with citrate and GSH as the stabilizer of Ag nanocrystals and the etchant. The as-prepared Ag nanoclusters show good pH-switchable agglomeration and dispersion accompanied with the reversible agglomeration induced signal quenching. The pH-regulated behavior mechanism has been discussed, and the Ag nanoclusters is introduced as a probe to establish regenerable biosensing platform for urea and glucose detection.
A novel approach to produce stretchable and deformable printed circuit boards is reported and applied to enable the realization of metamorphic electronic products, which conform to take on new three-dimensional shapes. The test structures morph from planar, to spherical, to cone-like topologies.
We develop a new type of flexible nanohybrid microelectrode by decorating high dense PtAu alloy nanoflowers on 3D porous ionic liquid functionalized graphene wrapped activated carbon fiber. In virtue of the unique array of structural and chemical properties, the resultant hierarchical nanohybrid microelectrode exhibits a collection of good sensing performances, and can be used in near-cell sensitive detection of cancer biomarker secreted from different female cancer cells in normal state and treated by antitumor drug, which provides important information in distinguishing different cancer cells and normal cells and evaluating the therapeutic activity of antitumor drug towards the live cancer cells.
Selenium atoms were selectively introduced in particular locations such as the pseudo-edge sites of hole-cluster defects in the basal plane and edge defect sites of the fully amorphorized surface of reduced graphene oxide (rGO), inducing a dramatic change of electrical transport properties of rGO by electron doping.
