Multibioinspired JANUS Membranes with Spatial Surface Refreshment for Enhanced Fog Collection

Inspired by the microstructures and functions of Namib desert beetles, Shorebird's beaks and tree roots, a multibioinspired Janus membrane is designed. The membrane can generate not only a surface refreshment in the horizontal direction due to hybrid wettability, but also a vertical one enabled by curvature gradient and capillary wicking, which shows...

Flexible PDMS/Al2O3 Nanolaminates for the Encapsulation of Blue OLEDs

The polydimethylsiloxane (PDMS)/Al2O3 multilayered encapsulation films with distinct interfaces are obtained by exposing the PDMS sublayer to the O2 plasma. Besides, the epoxy layer helps improve the flexibility of the barrier further by adjusting the neutral axis position. The lifespan of the OLEDs encapsulated with the multilayered structure is around...

Fluorescent Hydrogel Producing ZnO for Colorimetric Detection of Glutathione and Cysteine

ZnO as a biosensor realizes the advantageous quality in facial and rapid detection of GSH and Cys by naked eyes. Abstract Supramolecular hydrogels, based on non-covalent interaction, have outstanding properties, but it is still a big challenge to design hydrogels with higher mechanical properties. In this study, hydrogels with adjustable mechanical...

Recent Aspects in Membrane Separation for Oil/Water Emulsion

In the present time, many scientists are feeling responsible to save the world from run-off of oil resources together with water poverty. Tailoring membranes to separate oil/water emulsion and re-use of oil and water is a great challenge. Inorganic nanoparticles/or green co-polymers for chemical grafting produce a membrane with super wetting properties...

Fluorocarbon Vapors Slow Down Coalescence in Foams

Tuning the stability of liquid foams remains a major challenge for the optimization of applications. The use of co-adsorbates from the gas phase is a new possibility to control this stability. It is shown that fluorocarbon (FC) vapors not only prevent gas exchange between bubbles, as widely known, but also efficiently increase the stability of the foam...

Aminoclay‐Graphene Oxide Composite for Thin‐Film Composite Reverse Osmosis Membranes with Unprecedented Water Flux and Fouling Resistance

The effect of incorporating aminoclay-graphene oxide composite into thin-film composite (TFC)-reverse osmosis membranes is investigated to improve the desalination efficiency of brackish water. For the optimized modified membrane (M30) the flux increased ≈3.27 times compared to the unmodified TFC membrane at 20 bar pressure for 2000 ppm feed sodium...

Stable Field Electron Emission and Plasma Illumination from Boron and Nitrogen Co‐Doped Edge‐Rich Diamond‐Enhanced Carbon Nanowalls

Investigation of the novel diamond-enhanced carbon nanowall nanostructures grown in a microwave plasma is demonstrated. Nanowalls show a noticeable enhancement in the field electron emission characteristics viz. a low turn-on field and a large field enhancement factor. Graphene phases and diamond sharp edges enhance the field electron emission properties....
