Oak Ridge National Laboratory researchers developed a fiber to adsorb uranium from seawater. Researchers at the Pacific Northwest National Laboratory exposed the fibers to Pseudomonas fluorescens and used the Advanced Photon Source at Argonne National Laboratory to create a 3-D X-ray microtomograph to determine that the fiber structure was not damaged by the organism.

Pacific Northwest National Laboratory developed process makes it more feasible for the auto industry to incorporate magnesium alloys into structural components. The method has the potential to reduce costs by eliminating the need for rare-earth elements, while simultaneously improving the material's structural properties.

 

The PNNL team designed and commissioned an industrial version of their idea: A one-of-a-kind, custom built Shear Assisted Processing and Extrusion machine — coining the acronym for ShAPE™.

The image was taken during micro-pillar milling using a dual beam FIB-SEM.

 

The material is TiCN thin CVD coating deposited on a hard metal substrate. Due to its columnar grain microstructure, we have this "cristal visual effect" that surround the pillar while ions milling.

When the pillar will have its final cylindrical shape, it will be punched to investigate the deformation behaviour of these tribological layers.

Graphic illustrates cutaway views of two kinds of smart window showing how they can selectively transmit or block certain wavelengths of light.

 

Smart windows can switch between a transparent state and blocking state, a feat achieved by taking advantage of materials that reversibly shape-shift. Some materials alter in response to heat or electricity (shown); others respond to a magnetic field, mechanical strain or humidity levels.

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.

Photography milled out by FIB on a Si wafer. The technique consists on converting the intensity of each pixel in an 8-bit image to an equivalent exposure time. This data can be transferred to the microscope through a stream file with contains information about the spatial coordinate of the ion beam and its associated exposure time for each particular position. With an appropriate spot size of the Ga+ beam, depending upon magnification and the target material, an incredibly high definition of the photography can be achieved through topographic contrast.
