Supercapacitors from scrap tires

Some of the 300 million tires discarded each year in the United States alone could be used in supercapacitors for vehicles and the electric grid using a new technology.

Rsearchers produce first 2D perovskite hybrid sheets

To the growing list of two-dimensional semiconductors, such as graphene, boron nitride, and molybdenum disulfide, whose unique electronic properties make them potential successors to silicon in future devices, you can now add hybrid organic-inorganic perovskites. However, unlike the other contenders, which are covalent semiconductors, these 2D hybrid perovskites are ionic materials, which gives them special properties of their own.

Chip-based technology enables reliable direct detection of Ebola virus

Hybrid device integrates a microfluidic chip for sample preparation and an optofluidic chip for optical detection of individual molecules of viral RNA.

Proposed standards for triboelectric nanogenerators could facilitate comparisons

To provide a means for both comparing and selecting these energy-harvesting nanogenerators for specific applications, the Georgia Institute of Technology research group that pioneered the triboelectric nanogenerator (TENG) technology has now proposed a set of standards for quantifying device performance. The proposal evaluates both the structural and materials performance of the four major types of TENG devices.

Designed defects in liquid crystals can guide construction of nanomaterials

Imperfections running through liquid crystals can be used as miniscule tubing, channeling molecules into specific positions to form new materials and nanoscale structures.

Organic electronics with an edge

Two-dimensional organic lattices are easier and safer to work with than inorganic materials for spintronic and quantum computing applications.

A magnetic memory bubbling with opportunity

Ultrafast laser pulses can manipulate 'bubble' domains for future spintronic and logic devices.
