New technique reveals powerful, 'patchy' approach to nanoparticle synthesis

DOE/Brookhaven National Laboratory

Patches of chain-like molecules placed across nanoscale particles can radically transform the optical, electronic, and magnetic properties of particle-based materials. Now, scientists have used cutting-edge electron tomography techniques -- a process of 3-D reconstructive imaging -- to pinpoint the structure and composition of the polymer nano-patches.

Amazon rainstorms transport atmospheric particles for cloud formation

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Understanding how tiny particles emitted by cars and factories affect Earth's climate requires accurate climate modeling and the ability to quantify the effects of these pollutant particles vs. particles naturally present in the atmosphere. To better understand the baseline, scientists describe how they tracked particles in the largely pristine atmosphere over the Amazon rainforest -- effectively turning back the clock a few hundred years.

Scientists find static 'stripes' of electrical charge in copper-oxide superconductor

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Understanding the electronic ordering in copper-oxide superconductors could help scientists find the 'recipe' for raising the temperature at which current can flow through these materials without energy loss.

Tomoyasu Mani wins 2016 Blavatnik Regional Award for Young Scientists

DOE/Brookhaven National Laboratory
Grant and Award Announcement

Mani is being recognized for his work at Brookhaven Lab to understand the physical processes occurring in organic materials used to harness solar energy.

Still no 'sterile' neutrinos, but the search goes on

DOE/Brookhaven National Laboratory

Reports of the non-existence of the so-called 'sterile' neutrino are premature, say scientists at the US Department of Energy's Brookhaven National Laboratory -- even as they release results from two experiments that further limit the places this elusive particle may be hiding.

Enhancing the superconducting properties of an iron-based material

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

By bombarding the material with low-energy protons, scientists doubled the amount of current the material could carry without resistance, while raising the temperature at which this superconducting state emerges. Their method could be used to improve the performance of superconducting wires and tapes for electric vehicles, wind turbines, medical imaging devices, and other applications.
