New interferometer could simplify materials research

(PhysOrg.com) -- “Most current hard x-ray interferometers are based on crystals, which require their high quality and high mechanical stability,” Anatoly Snigirev tells PhysOrg.com. “This can make x-ray interferometry ...

Marine bacterium sheds light on control of toxic metals

An ocean-dwelling bacterium has provided fresh insights into how cells protect themselves from the toxic effects of metal ions such as iron and copper, in research led by the University of East Anglia (UEA).

New theory shows how strain makes for better catalysts

Brown University researchers have developed a new theory to explain why stretching or compressing metal catalysts can make them perform better. The theory, described in the journal Nature Catalysis, could open new design ...

MiNT protein a fresh target to attack disease

A two-faced protein in a chain that regulates iron and other elements in cells could provide a new target to treat cancer, diabetes and other diseases.

Tiny device grabs more solar energy to disinfect water faster

In many parts of the world, the only way to make germy water safe is by boiling, which consumes precious fuel, or by putting it out in the sun in a plastic bottle so ultraviolet rays will kill the microbes. But because UV ...

Substrates change nanoparticle reactivity

(Phys.org)—Nanoscale materials tend to behave differently than their bulk counterparts. While there are many theories as to why this happens, technological advances in scanning tunneling microscopy (STM) have allowed researchers ...

Nano-antioxidants prove their potential

Injectable nanoparticles that could protect an injured person from further damage due to oxidative stress have proven to be astoundingly effective in tests to study their mechanism.
