Hierarchical 3D-printing of nanoporous gold could 'revolutionize' electrochemical reactor design

Scientists report on the hierarchical 3D printing of nanoporous gold, a proof of concept that could revolutionize the design of chemical reactors.

Terahertz spectroscopy enters the single-molecule regime

Researchers showed that long-wavelength terahertz spectroscopy can detect motion of single molecules, not just molecular ensembles. They used a single-molecule transistor design, where pairs of metal electrodes trap isolated C60 molecules, focus the THz beam onto them, and measure current change caused by THz-induced oscillation.

Neutrophil nanosponges soak up proteins that promote rheumatoid arthritis

Engineers have developed neutrophil nanosponges that can safely absorb and neutralize a variety of proteins that play a role in the progression of rheumatoid arthritis.

2D material cannibalizes itself for atomic building blocks

Scientists induced a two-dimensional material to cannibalize itself for atomic 'building blocks' from which stable structures formed.

Watching atoms and electrons at work

Layered crystals are used worldwide as a basis for exploring the nano-cosmos.

Dual-layer solar cell developed at UCLA sets record for efficiently generating power

Materials scientists have developed a highly efficient thin-film solar cell that generates more energy from sunlight than typical solar panels, thanks to its double-layer design.

Sampling for nanomaterial workplace exposure in the air and on surfaces

A new reports provides an assessment of methods of sampling and characterizing engineered nanomaterials in the air and on surfaces in the workplace.
