Conjugated polymer nanodots as ultrastable long-term trackers to understand mesenchymal stem cell therapy in skin regeneration
Stem cell–based therapies hold great promise in providing desirable solutions for diseases that cannot be effectively cured by conventional therapies. To maximize the therapeutic potentials, advanced cell tracking probes ...
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.
Novel silicon–nickel cone arrays for high performance LIB anodes
We report on a high performance silicon anode based on silicon–nickel cone arrays. The composite electrode exhibits good capacity retention and remarkable rate performance. A de-lithiation capacity of 2639, 2341, 2042, ...
Free-standing bimetallic nanorings and nanoring arrays made by on-wire lithography
This paper describes a new strategy for synthesizing free-standing bimetallic nanorings and nanoring arrays based upon on-wire lithography and a galvanic replacement reaction. The strategy allows one to tune the diameter, ...
Synergistic photocatalytic aerobic oxidation of sulfides and amines on TiO2 under visible-light irradiation
Selective photocatalytic aerobic oxidation, which can be conducted under ambient conditions, is of great importance towards achieving sustainable chemistry. However, its practical applications are undermined by several ...
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 ...
Assembly of graphene sheets into 3D macroscopic structures
Integration of graphene sheets, 2D nanoscale building blocks, into 3D macroscopic assemblies and ultimately into a functional system is essential to explore the advanced properties of individual graphene sheets for macroscopic ...
Semiconductive, one-dimensional, self-assembled nanostructures based on oligopeptides with π-conjugated segments
π Stacking between the β sheets: A newly designed π-conjugated peptide can be assembled into a one-dimensional nanostructure with strong π–π intermolecular electronic communication. A nanoelectronic device based on the ...
High-performance and tailorable pressure sensor based on ultrathin conductive polymer film
A highly sensitive and tailorable pressure sensor is designed based on the variation of contact resistance between an Au covered micropillar array and a conductive polymer film. The sensitivity of such pressure sensors can ...
Free-standing one-dimensional plasmonic nanostructures
The field of plasmonics has become one of the most interesting and active research areas in nanotechnology, enabling numerous fundamental studies and applications. The ability to tailor the size, shape, and environment of ...
