Glass-based ultraviolet absorbers act as 'biological shields'

A special metal oxide glass can help protect living cells by absorbing and blocking damaging ultraviolet rays.

New process enables easier isolation of carbon nanotubes

A new method enables isolation and sorting of semiconducting single-walled carbon nanotubes with little damage and at high purity.

Subatomic silver clusters that self-assemble on cyclic peptide nanotubes

Researchers have described, for the first time the way small clusters of silver metal set weak interactions with other organic molecules.

Localized oxidative killing of tumor cells by glassy iron nanoparticles

Scientists describe their design and synthesis of a special amorphous state of nanoparticulate iron, which can locally release reactive iron species in the acidic and hydrogen peroxide rich environment of cancer cells, providing new possibilities for theranostics and chemodynamic therapies.

Copper deposition to fabricate tiny 3D objects

A new 3D microprinting process allows scientists to easily manufacture tiny, complex metal components.

Seeing the big picture in photosynthetic light harvesting

Researchers create first multiple Aantennae model of Photosystem II.

Good solar cells from bad effects

Researchers used numerical simulations to demonstrate that energy dissipation and decoherence, which were thought to reduce solar cell efficiency, are counterintuitively helpful for the development of more efficient photovoltaics, offering a new guide to finding efficient photovoltaic materials.
