Researchers create successful predictions of combustion reaction rates

Researchers at Argonne and Sandia National Laboratories have demonstrated, for the first time, a method to successfully predict pressure-dependent chemical reaction rates, an important breakthrough in combustion and atmospheric chemistry that is expected to benefit auto and engine manufacturers, oil and gas utilities and other industries that employ combustion models.

In a study published in Nature Chemistry, Northwestern researchers have discovered that in the mammalian egg, zinc is stored in tiny packages just below the cell surface. These packages are released in waves following fertilization in events called ‘zinc sparks.’ These sparks are akin to neurotransmitter release in the brain or insulin release in the pancreas. This fluorescence image of an egg labeled for zinc (green) and DNA (blue) depicts how the egg stores zinc in thousands of tiny packages. These are released during fertilization to form the zinc spark. Image credit: Northwestern University. Click to view larger.
Stunning zinc fireworks when egg meets sperm

Sparks literally fly when a sperm and an egg hit it off. The fertilized mammalian egg releases from its surface billions of zinc atoms in “zinc sparks,” one wave after another, found a Northwestern University-led interdisciplinary research team that includes experts from the Advanced Photon Source at Argonne.

Underground helium travels to the Earth’s surface via aquifers, new study says

Before it can put the party in party balloons, helium is carried from deep within the Earth’s crust to the surface via aquifers, according to new research published this week in Nature Geosciences.

The synchrotron X-ray scanning tunneling microscopy concept allowed Argonne National Laboratory and Ohio University researchers to achieve a recording-breaking resolution of a nanoscale material. They combined of a synchrotron X-ray as a probe and a nanofabricated smart tip as a detector to fingerprint individual nickel clusters on a copper surface at a two-nanometer resolution and at the ultimate single-atomic height sensitivity. And by varying the photon energy, researchers successfully measured photoionization cross sections of a single nickel nanocluster – opening the door to new opportunities for chemical imaging of nanoscale materials.
