Two-dimensional heterospectral correlation analysis of the redox-induced conformational transition in cytochrome c using surface-enhanced Raman and infrared absorption spectroscopies on a two-layer gold surface
The heme protein cytochrome c adsorbed to a two-layer gold surface modified with a self-assembled monolayer of 2-mercaptoethanol was analyzed using a two-dimensional (2D) heterospectral correlation analysis that combined ...
A colorimetric logic gate based on free gold nanoparticles and the coordination strategy between melamine and mercury ions
A colorimetric logic gate based on free gold nanoparticles is presented with melamine and Hg2+, as well as its colorimetric detection of Hg2+ with good selectivity and sensitivity.
Three-dimensional CdS-titanate composite nanomaterials for enhanced visible-light-driven hydrogen evolution
3D Hierarchical echinus-like titanate spheres (HETSs), serving as the supporting material for CdS nanoparticles, are synthesized via a fast one-step hydrothermal method. The obtained 3D CdS–HETS composite materials show ...
Ambient fabrication of large-area graphene films via a synchronous reduction and assembly strategy
A synchronous reduction and assembly strategy is designed to fabricate large-area graphene films and patterns with tunable transmittance and conductivity. Through an oxidation–reduction reaction between the metal substrate ...
Clean unzipping by steam etching to synthesize graphene nanoribbons
A simple, clean method of steam etching carbon nanotubes is reported for the synthesis of graphene nanoribbons. The chemical mechanism of carbon nanotube unzipping is also discussed. As an anode catalyst, as-prepared ...
Atomically flat, large-sized, two-dimensional organic nanocrystals
Large-sized, 2D single crystals of perylene are grown by both solution-cast and physical vapor transport methods. The crystals have a atomically flat parallelogram morphology and the aspect ratios of the lateral extension ...
Highly stretchable, integrated supercapacitors based on single-walled carbon nanotube films with continuous reticulate architecture
Highly stretchable, integrated, single-walled carbon nanotube (SWCNT) film supercapacitors are prepared by combining directly grown SWCNT films with continuous reticulate architecture with polydimethylsiloxane with enhanced ...
Visible photoresponse of single-layer graphene decorated with TiO2 nanoparticles
A simple method to fabricate a visible light-detectable hybrid nanodevice based on TiO2 nanoparticles and pristine graphene, ideally combining the advantages of both, is demonstrated. High photosensitivity of the hybrid ...
Reciprocal response of human oral epithelial cells to internalized silica nanoparticles
Silica nanoparticles (SiO2 NPs) are one of the most widely used engineered nanoparticles and can been found in a wide range of consumer products. Despite their massive global production scale, little is known about their ...
Synergistic modulation of surface interaction to assemble metal nanoparticles into two-dimensional arrays with tunable plasmonic properties
A simple strategy based on the synergistic modulation of inter-particle and substrate-particle interaction is applied for the large-scale fabrication of two-dimensional (2D) Au and Ag nanoparticle arrays. The surface charge ...
