Large supercrystals promise superior sensors

Sandia Labs News Release (08/01/18)

Hongyou Fan holds a container enclosing gold supercrystals in front of a small-angle X-ray scattering instrument.Using an artful combination of nanotechnology and basic chemistry, Sandia National Laboratories researchers, including CINT affiliate scientist Hongyou Fan, have encouraged gold nanoparticles to self-assemble into unusually large supercrystals that could significantly improve the detection sensitivity for chemicals in explosives or drugs.

CINT scientsts to be part of 2018 DOE Energy Frontier Research Center

LANL News Release (07/24/18)

The figure illustrates the three planned thrusts for the project: non-equilibrium point defects, the coupled transport of defects and alloying elements, and transport of species across interfaces.CINT scientist Nan Li and CINT affiliate scientist Yongqiang Wang are part of the LANL team that was recently awarded EFRC funding. The new center, called FUTURE (Fundamental Understanding of Transport Under Reactor Extremes), will explore the coupling of radiation damage and corrosion in order to predict irradiation-assisted corrosion in passivating and non-passivating environments for materials in nuclear energy systems.

LANL News Release (07/24/18)

SeafoodCINT postdoc Yuxiang Chen was recognized for his outstanding presentation at the 2018 DisrupTech, an event that showcases technologies with the potential to “disrupt” existing markets or even to create new ones. Yuxiang won the “Most Fundable Technology” award for his presentation “NanoCluster Beacons: Fast Testing for Food Safety.” The $25,000 funding award will help him improve his technology that quickly and accurately tests pathogens in food.

Shining light on excited-state dynamics in perovskite materials

LANL Science Brief (07/17/18)

Theoretically predicted structures of methylammonium lead iodide perovskiteHybrid organic-inorganic perovskites are materials with attractive optoelectronic properties including exceptional solar cell performance. In this latest research published in Nature Communications, CINT scientist Sergei Tretiak and collaborators show that polaron formation via nuclear dynamics in perovskite may be important for efficient charge separation and collection.

Coherent exciton-vibrational dynamics and energy transfer in conjugated organics

LANL Science Brief (07/03/18)

Coherent electron-vibrational dynamics can appear after so-called non-radiative relaxation when instead of emitting as light, electronic energy is transferred to vibrations or heat. In a new theoretical study described in a Nature Communications paper, CINT scientist Sergei Tretiak and collaborators demonstrate the appearance of coherent electron-vibrational dynamics after so-called non-radiative relaxation. The effect appears as a ‘sloshing’ of electron density back and forth between molecular sites.

Light mixer generates 11 colors simultaneously

Sandia Labs News Release (06/28/18)

Sandia National Laboratories postdoctoral appointee Polina Vabishchevich, left; and Senior Scientist Igal Brener work in their optics lab.Research by CINT scientists Igal Brener and John Reno and their collaborators shows how a metamaterial made up of an array of nanocylinders mixes two laser pulses of near infrared light to produce 11 waves of light. The light ranges in color from the near infrared, through the colors of the rainbow, to ultraviolet. This work was published in Nature Communications. Igal says, "Without CINT's specialized femtosecond laser system, it would have been very challenging to perform these measurements."

Carbon nanotube optics poised to provide pathway to optical-based quantum cryptography and quantum computing

LANL News Release (06/18/18)

Depiction of a carbon nanotube defect site generated by functionalization of a nanotube with a simple organic molecule.Researchers at CINT and partners in France and Germany are exploring the enhanced potential of carbon nanotubes as single-photon emitters for quantum information processing. In describing their work published in Nature Materials, CINT scientist Steve Doorn says, "In addition to defining the state of the art, we wanted to highlight where the challenges are for future progress and lay out some of what may be the most promising future directions for moving forward in this area. Ultimately, we hope to draw more researchers into this field."

A bit of quantum logic

BES Science Highlight (06/18/18)

Angled view scanning electron microscope image of the device gate structure.Quantum computers could tackle problems that current supercomputers can’t. Quantum computers rely on quantum bits, or "qubits," which represent data by the binary state of electron spins. Two systems existed to create qubits—donor atoms and quantum dots. CINT researchers and collaborators have successfully integrated the systems. This hybrid approach, which has remained elusive until now, exploits the advantages of the two qubit systems.

Tackling a global challenge in Boston

Saudi Aramco News (06/13/18)

U.S. senators and their staff members had the opportunity to view how corrosion impacts infrastructure in their state.Corrosion is a global problem that costs the world $2.5 trillion annually. This chemical process is most often seen on metal surfaces as rust and can result in catastrophic failure of infrastructure, such as bridges. Researchers at the Aramco Research Center-Boston have teamed up with scientists at CINT to investigate the nanoscale mechanisms responsible for corrosion initiation and progression in steel.
