Using polarized reflective light, PNNL scientists discovered a novel new compound—Cd3Ge2As4. This breakthrough was made while conducting experimental work to develop new semiconductors. The new material potentially has applications in infrared optics and electronics. The specimen was imaged in cross-polarized reflected light. The different colors are due to birefringence in the crystal caused by light traveling at different speeds along different crystallographic axes. The image was captured by scientist Brad Johnson. The team of researchers on this project includes Brian Riley, Joe Ryan, John McCloy, Jarrod Crum, and SK Sundaram.
This image was a part of the 2010 PNNL Science as Art contest.

A team of researchers led by the University of California San Diego have discovered what’s responsible for making the teeth of the deep-sea dragonfish transparent. This unique adaptation, which helps camouflage the dragonfish from their prey, results from their teeth having an unusually crystalline nanostructure mixed with amorphous regions. The findings could provide “bioinspiration” for researchers looking to develop transparent ceramics.

Attendees gather for conversation and breakfast at the DMMM4 Fresh Coffee, Fresh Ideas: Diversity and Inclusion Breakfast as a kick off to the DMMM4 programming and networking.
A panel of five experts representing industry, academia, and government provided an overview of their own experiences and career journeys followed by questions from graduate and undergraduate students.
In recent decades, developments in software and hardware technologies have created dramatic shifts in design, manufacturing and research. Software technologies have facilitated automated process and new solutions for complex problems. Computation has also become a platform for creativity through generative art and design. New hardware platforms and digital fabrication technologies have similarly transformed manufacturing, offering more efficient production and mass customization. Such advances have helped catalyzed the maker-movement, democratizing design and maker culture. This influx of new capabilities to design, compute and fabricate like never before, has sparked a renewed interest in material performance.
We are now witnessing significant advances in active matter, 3D/4D Printing, materials science, synthetic biology, DNA nanotechnology and soft robotics, which have led to the convergence of software, hardware and material technologies and the growing field of programmable materials.
This conference was about the emerging field of active matter and programmable materials that bridges the worlds of art, science, engineering and design, demonstrating new perspectives for computation, transformation and dynamic material applications.
If over the past few decades we have experienced a software revolution, and more recently, a hardware revolution, this conference aims to discuss the premises, challenges and innovations brought by today’s materials revolution. We can now sense, compute, and actuate with materials alone, just as we could with software and hardware platforms previously. How does this shift influence materials research, and how does it shape the future of design, arts, and industrial applications? What tools and design processes do we need to advance, augment and invent new materials today? What are the key roles that industry, government, academic and public institutions can play in catalyzing the field of programmable materials?
This two-day conference consisted of a range of talks and lively discussion from leading researchers in materials science, art & design, synthetic biology and soft-robotics along with leaders from government, public institutions and industry.

This extremely tiny nanocrystal of zinc oxide is actually luminescent (glowing). Scientists at Argonne work to create new kinds of materials to explore their properties, which might be the key to new technological breakthroughs in batteries or electronics. The image is straight from a scanning electron microscope—unaltered in any way.
