Structural diversity of bulky graphene materials
The unique two-dimensional (2D) structure and chemical properties of graphene and its derivatives make it a distinctive nanoscale building block for constructing novel bulky architectures with different dimensions, such ...
A synergistic capture strategy for enhanced detection and elimination of bacteria
Despite the advanced detection and sterilization techniques available today, the sensitive diagnosis and complete elimination of bacterial infections remain a significant challenge. A strategy is reported for efficient ...
Orthogonally engineering matrix topography and rigidity to regulate multicellular morphology
Programmable polymer substrates, which mimic the variable extracellular matrices in living systems, are used to regulate multicellular morphology, via orthogonally modulating the matrix topography and elasticity. The ...
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 ...
