Read moreGraphene composite leads to breakthrough in rechargeable battery applications
Researchers demonstrate that a composite paper - made of interleaved molybdenum disulfide and graphene nanosheets - can be both an active material to efficiently store sodium atoms and a flexible current collector. The newly developed composite paper can be used as a negative electrode in sodium-ion batteries.

Read moreCell membrane model studied as future diagnostic tool
Researchers have used a NIST-developed laboratory model of a simplified cell membrane to accurately detect and measure a protein associated with a serious gynecological disease, bacterial vaginosis, at extraordinarily low concentrations. The work illustrates how the artificial membrane could be used to improve disease diagnosis.

Read moreLearning more about piezoelectric
Though piezoelectrics are a widely used technology, there are major gaps in our understanding of how they work. Now researchers at the National Institute of Standards and Technology (NIST) and Canada's Simon Fraser University believe they've learned why one of the main classes of these materials, known as relaxors, behaves in distinctly different ways from the rest and exhibit the largest piezoelectric effect.

Read moreNext generation of chiroptical nanomaterials?
Researchers have shown that free-base and nickel porphyrin-diaminopurine conjugates are formed by hydrogen-bond-directed assembly on single-stranded oligothymidine templates of different lengths into helical multiporphyrin nanoassemblies. The nanoassemblies have highly modular structural and chiroptical properties.
