Scientists at the US Department of Energy's Ames Laboratory have made advances in angle-resolved photoemission spectroscopy (ARPES) to help better study electronic properties of new materials.
18-Jun-2015 Adapting nanoscience imaging tools to study ants' heat-deflecting adaptations
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.
15-Jun-2015 What the blank makes quantum dots blink?

Further, the synthesis method opens up possible variations that could lead to materials presently unknown or impossible to make with existing techniques.
27-May-2015 Spiraling laser pulses could change the nature of graphene
A new study predicts that researchers could use spiraling pulses of laser light to change the nature of graphene, turning it from a metal into an insulator and giving it other peculiar properties that might be used to encode information.
27-May-2015 The 'why' of models
An international team of researchers from Oak Ridge National Laboratory, Macquarie University, the University of Western Sydney and the Max Planck Institute for Biogeochemistry set out to assess how two Free-Air CO2 Enrichment projects compared to eleven vegetation models that simulate various ecological processes. Instead of only benchmarking whether or not an individual model matched the experimental data, the researchers developed an 'assumption-centered' approach to evaluate why certain models performed better than others.
21-May-2015 Shape-shifting plastic
Researchers from Oak Ridge National Laboratory, Washington State University and the University of Idaho have developed a process to make a thermoset that can be reshaped and reused. The new plastic is a shape-memory polymer, so named because the material can 'remember' its original shape and return to it after being deformed with heat or other forces.
