Adapting nanoscience imaging tools to study ants' heat-deflecting adaptations

DOE/Brookhaven National Laboratory

A new study shows that the tiny hairs of Saharan silver ants possess crucial adaptive features that allow the ants to regulate their body temperatures and survive the scorching hot conditions of their desert habitat. To study how the hairs allow the creatures to control electromagnetic waves in this manner, the Columbia Engineering research team turned to the resources and expertise available at Brookhaven Lab's Center for Functional Nanomaterials.

Scientists see ripples of a particle-separating wave in primordial plasma

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Scientists in the STAR collaboration at the Relativistic Heavy Ion Collider, a particle accelerator exploring nuclear physics and the building blocks of matter at the US Department of Energy's Brookhaven National Laboratory, have new evidence for what's called a 'chiral magnetic wave' rippling through the soup of quark-gluon plasma created in RHIC's energetic particle smashups.

Engineering phase changes in nanoparticle arrays

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Scientists at the US Department of Energy's Brookhaven National Laboratory have just taken a big step toward the goal of engineering dynamic nanomaterials whose structure and associated properties can be switched on demand. In a paper appearing in Nature Materials, they describe a way to selectively rearrange the nanoparticles in three-dimensional arrays to produce different configurations, or phases, from the same nano-components.

DNA double helix does double duty in assembling arrays of nanoparticles

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

In a new twist on the use of DNA in nanoscale construction, scientists at the US Department of Energy's Brookhaven National Laboratory and collaborators put synthetic strands of the biological material to work in two ways: They used ropelike configurations of the DNA double helix to form a rigid geometrical framework, and added dangling pieces of single-stranded DNA to glue nanoparticles in place.

Visualizing how radiation bombardment boosts superconductivity

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Study shows how heavy-ion induced atomic-scale defects in iron-based superconductors 'pin' potentially disruptive quantum vortices, enabling high currents to flow unimpeded. The study opens a new way forward for designing and understanding superconductors that can operate in demanding high-current, high magnetic field applications, such as zero-energy-loss power transmission lines and energy-generating turbines.

Intense lasers cook up complex, self-assembled nanomaterials

DOE/Brookhaven National Laboratory

New technique developed at Brookhaven Lab makes nanoscale self-assembly 1,000 times faster and could be used for industrial-scale solar panels and electronics.

Giant electromagnet arrives at Brookhaven Lab to map melted matter

DOE/Brookhaven National Laboratory

A 20-ton superconducting magnet traveled from California's SLAC Lab to New York's Brookhaven Lab as part of a proposed upgrade to the Relativistic Heavy Ion Collider's PHENIX detector.

Scientists use nanoscale building blocks and DNA 'glue' to shape 3-D superlattices

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Taking child's play with building blocks to a whole new level-the nanometer scale-scientists at the US Department of Energy's Brookhaven National Laboratory have constructed 3-D 'superlattice' multicomponent nanoparticle arrays where the arrangement of particles is driven by the shape of the tiny building blocks. The method uses linker molecules made of complementary strands of DNA to overcome the blocks' tendency to pack together in a way that would separate differently shaped components.
