Vanadium pentoxide-based cathode materials for lithium-ion batteries : morphology control, carbon hybridization, and cation doping
Vanadium pentoxide (V2O5) is a promising cathode material for high-performance lithium-ion batteries (LIBs) because of its high specific capacity, low cost, and abundant source. However, the practical application of V2O5 ...
Recycling bacteria for the synthesis of LiMPO4 (M = Fe, Mn) nanostructures for high-power lithium batteries
In this work, a novel waste-to-resource strategy to convert waste bacteria into a useful class of cathode materials, lithium metal phosphate (LiMPO4; M = Fe, Mn), is presented. Escherichia coli (E. coli) bacteria used for ...
Fabrication of flexible thermoelectric thin film devices by inkjet printing
Ink-jet printing of thermoelectric nanomaterials is successfully used to fabricate flexible thin film TE devices for power generation and cooling.
n-type carbon nanotubes/silver telluride nanohybrid buckypaper with a high-thermoelectric figure of merit
N-type thermoelectric materials was made from CNT buckypapers. We used Ag2Te to achieve electron injection to the CNTs. The thermoelectric characterizations on more than 50 samples show that the CNTs/Ag2Te hybrids exhibit ...
Platinum and palladium nanotubes based on genetically engineered elastin-mimetic fusion protein-fiber templates : synthesis and application in lithium-O2 batteries
The coupling of proteins with self-assembly properties and proteins that are capable of recognizing and mineralizing specific inorganic species is a promising strategy for the synthesis of nanoscale materials with controllable ...
Preparation of novel 3D graphene networks for supercapacitor applications
Chemical vapor deposition is used to prepare novel 3D graphene networks, with ethanol as the carbon source. These networks are used as templates for the construction of graphene/metal oxide composite-based supercapacitor ...
A facile, relative green, and inexpensive synthetic approach toward large-scale production of SnS2 nanoplates for high-performance lithium-ion batteries
A facile, environmentally friendly, and economical synthetic route for production of large-amounts (gram scale) of two-dimensional (2D) layered SnS2 nanoplates is presented. The electrode fabricated from the SnS2 nanoplate ...
Growth of Si nanowires in porous carbon with enhanced cycling stability for Li-ion storage
Si nanowires are successfully grown in porous carbon by supercritical fluid-liquid-solid (SFLS) process, which show high specific capacities and charge–discharge cycling stability as anode materials for Li-ion storage. ...
Comparative studies on single-layer reduced graphene oxide films obtained by electrochemical reduction and hydrazine vapor reduction
The comparison between two kinds of single-layer reduced graphene oxide (rGO) sheets, obtained by reduction of graphene oxide (GO) with the electrochemical method and hydrazine vapor reduction, referred to as E-rGO and ...
Crystal structure and phototransistor behavior of N-substituted heptacence
6,8,15,17-Tetraaza-1.18,4.5,9.10,13.14-tetrabenzoheptacene (TTH, 1) has been prepared and characterized by single-crystal X-ray structure analysis. A phototransistor device based on TTH single crystal demonstrated that TTH ...
