A better way to control crystal vibrations
The vibrational motion of an atom in a crystal propagates to neighboring atoms, which leads to wavelike propagation of the vibrations throughout the crystal. The way in which these natural vibrations travel through the crystalline structure determine fundamental properties of the material. Now, researchers have shown that by swapping out just a small fraction of a material's atoms with atoms of a different element, they can control the speed and frequencies of these vibrations

Diamond 'spin-off' tech could lead to low-cost medical imaging and drug discovery tools
An international team has discovered how to exploit defects in nanoscale and microscale diamonds and potentially enhance the sensitivity of magnetic resonance imaging and nuclear magnetic resonance systems while eliminating the need for their costly and bulky superconducting magnets.

Self-assembling 3D battery would charge in seconds
A cross-campus collaboration led by Ulrich Wiesner, professor of engineering in the at Cornell University, addresses this demand with a novel energy storage device architecture that has the potential for lightning-quick charges. The group's idea: Instead of having the batteries' anode and cathode on either side of a nonconducting separator, intertwine the components in a self-assembling, 3D gyroidal structure, with thousands of nanoscale pores filled with the elements necessary for energy storage and delivery.

Supersonic waves may help electronics beat the heat
Researchers at the Department of Energy's Oak Ridge National Laboratory made the first observations of waves of atomic rearrangements, known as phasons, propagating supersonically through a vibrating crystal lattice -- a discovery that may dramatically improve heat transport in insulators and enable new strategies for heat management in future electronics devices.

Supercomputing the emergence of material behavior
Chemists at the University of California, San Diego designed the first artificial protein assembly (C98RhuA) whose conformational dynamics can be chemically and mechanically toggled. The Maverick GPU-based supercomputer at the Texas Advanced Computing Center simulated the system through an allocation on NSF-funded XSEDE, the Extreme Science and Engineering Discovery Environment. The research, published in April 2018 in Nature Chemistry, could help create new materials for renewable energy, medicine, water purification, and more.

Argonne's TechConnect hat trick
Argonne National Laboratory nanoscientist Anirudha Sumant has earned a TechConnect Innovation Award for the third year in a row. The award recognizes Sumant's work on nitrogen-incorporated ultrananocrystalline diamonds for application as a portable electron source in field emission cathodes. The technology was developed in partnership with Euclid Techlabs to create a superior field emission electron source for use in linear accelerators.

Quarks feel the pressure in the proton
Inside every proton in every atom in the universe is a pressure cooker environment that surpasses the atom-crushing heart of a neutron star. That's according to the first measurement of a mechanical property of subatomic particles, the pressure distribution inside the proton, which was carried out by scientists at the Department of Energy's Thomas Jefferson National Accelerator Facility.

Exploration of diverse bacteria signals big advance for gene function prediction
Scientists at Lawrence Berkeley National Laboratory, including researchers at the US Department of Energy Joint Genome Institute, have developed a workflow that enables large-scale, genome-wide assays of gene importance across many conditions. The study, 'Mutant Phenotypes for Thousands of Bacterial Genes of Unknown Function,' has been published in the journal Nature and is by far the largest functional genomics study of bacteria ever published.

Uncertainty in long-run economic growth likely points toward greater emissions, climate change costs
A challenge in estimating the extent and cost of damages from climate change over the next 100 years is developing forecasts of long-run economic growth. In a new study published in the Proceedings of the National Academy of Science, researchers from the University of Illinois and Yale University present a systematic method of integrating current models to develop forecasts of uncertainty in global and regional per capita economic growth rates through the year 2100.

Profiling extreme beams: Scientists devise new diagnostic for particle accelerators
The world's cutting-edge particle accelerators are pushing the extremes in high-brightness beams and ultrashort pulses to explore matter in new ways. To optimize their performance -- and to prepare for next-generation facilities that will push these extremes further -- scientists have devised a new tool that can measure how bright these beams are, even for pulses that last only quadrillionths or even quintillionths of a second.

Levitation yields better neutron-lifetime measurement
Being repulsive can have its advantages. In the case of an experiment at Los Alamos National Laboratory's linear accelerator, a repulsive magnetic field and a clever detector system are allowing ultracold neutrons to be levitated so their actual lifetimes can be more accurately measured.
