A pH-responsive surface has been fabricated by chemisorption of HS(CH2)9CH3 and HS(CH2)10COOH in an appropriate ratio onto a fractal-like gold structure. The exhibits superhydrophobicity acidic environment superhydrophilicity under basic conditions. Figure (right, top) shows acid droplet on the surface, while image below it base droplet.
Traffic noise has been regarded as one of the most annoying pollutions that induce severe hazards to human health, both physiological and psychological. The commonly used fibrous absorption materials are limited by their large density, poor sound ability at low frequencies, unsatisfactory fire-resistant ability. Here, we develop hierarchically structured elastic ceramic electrospun nanofibrous aerogels, which possess lightweight properties (density 13.29 mg cm–3) superior low-frequency (NRC...
Great challenges in investigating the release of drug complex cellular microenvironments necessitate development stimuli-responsive delivery systems with real-time monitoring capability. In this work, a smart nanocarrier based on fluorescence resonance energy transfer (FRET) is fabricated by capping graphene quantum dots (GQDs, acceptor) onto fluorescent mesoporous silica nanoparticles (FMSNs, donor) via ATP aptamer for ATP-triggered release. Under extracellular conditions, FMSNs remains...
Space cooling occupies a large portion of total building energy consumption, aggravating the crisis and restricting human sustainable development, thus an efficient energy-saving personal technology is in high demand. Recently, thermally conductive fillers, such as boron nitride (BN), are usually enriched to fibrous materials construct thermal management textiles. However, these fabrication processes complex time-consuming, resultant fail transmit moisture resist liquid water. Herein, we...
Significance Investigation of the charge transport mechanism across a monolayer redox active protein is important for fundamental understanding naturally occurring electron transfer processes, such as those in photosynthesis or respiration. Inelastic tunneling spectroscopy measurements may provide direct experimental evidence that charges are, fact, passing through molecules.

However, despite encouraging theoretical predictions, experimental realization such approach has remained elusive. Here we demonstrate experimentally that photoconductivity a model optoelectronic device can be modulated selective excitation vibrations. Using an...

Surprisingly efficient solid-state electron transport has recently been demonstrated through "dry" proteins (with only structural, tightly bound H2O left), suggesting as promising candidates for molecular (bio)electronics. Using inelastic tunneling spectroscopy (IETS), we explored electron–phonon interaction in metal/protein/metal junctions, to help understand electronic across the redox protein azurin. To that end an oriented azurin monolayer on Au is contacted by soft electrodes....

Anodization is a promising technique to form high-k dielectrics for low-power organic field-effect transistor (OFET) applications. However, the surface quality of dielectric, which mainly inherited from metal electrode, can be improved further than other fabrication techniques, such as sol–gel. In this study, we applied template stripping method fabricate single-crystalline OFET based on anodized AlOx dielectric. We found that largely improves roughness deposited Al and allows formation...
