As the techniques of additive manufacturing (AM), more popularly known as “3-D printing,” become ever more versatile and applicable for diverse purposes, they sometimes pose unique challenges that are not present with more traditional manufacturing methods. In additive-manufactured metals and alloys, such problems can result in microstructural defects that lead to reduced strength and stress resistance, an issue commonly addressed by post-build heat treatment. But this approach can also have undesirable side effects. Researchers from the National Institute of Standards and Technology used the U.S. Department of Energy’s Advanced Photon Source to examine the AM alloy Inconel 625 (IN625) in an effort to better understand the effects of heat treatment on AM alloy microstructure and phase evolution.

As the world moves away from incandescent light bulbs, light-emitting diodes (LEDs) are growing in popularity. They use significantly less energy and have far longer lifetimes than do the traditional incandescent bulbs, which are being phased out, and they don't contain mercury, as do compact fluorescents. LEDs do have a drawback, however. The phosphors that convert the single color produced by an LED into white light tend to produce a cool, bluish glow instead of the warmer, yellower color most people prefer.

Carbon monoxide (CO) is an insidious poison because it loves the iron in our blood; it pushes oxygen out of iron-based hemoglobin, leading to painful asphyxiation. This affinity for iron comes in handy in a newly created material that can absorb carbon monoxide far better than other materials, with potential applications in industrial processes like syngas production, where CO is a key player, and reactions where CO is an unwanted contaminant. A number of characterization and measurement techniques contributed to this groundbreaking research, including critical experiments at the U.S. Department of Energy’s Advanced Photon Source.

Nuclear power is one of the best ways currently available to supply clean, baseload electric power to the U.S. over the long term. But reserves of good uranium ore to fuel those plants are diminishing. By 2100 there will not be enough recoverable uranium left in terrestrial mines to meet the demands of existing power plants. However, if we cannot mine uranium on land, we may be able to sift it from the sea: The oceans contain huge reserves of uranium dissolved in seawater. State-of-the-art polymer fabrics soaked in seawater can recover 7 to 8 grams of uranium over a span of 30 days.

A novel gold compound with an “extra” electron compared to its chemical cousins is predicted to be a 3D Dirac semimetal, a relatively new class of electronic materials in which electrons behave as though they are massless, leading to high mobilities and unusual physics. The discovery, made at the U.S. Department of Energy’s Advanced Photon Source (APS), expands the search for possible thermoelectric materials (which make up Peltier coolers and thermoelectric generators) to include compounds with gold-gold bonds that stabilize "abnormal" electron counts. Such materials have very fast-moving electrons that could be used in circuits. Alternatively, these semimetals may have applications for solid-state cooling or heating.

Even as our electronic devices become ever more sophisticated and versatile, battery technology remains a stubborn bottleneck, preventing the full realization of promising applications such as electric vehicles and power-grid solar energy storage. Among the limitations of current materials are poor ionic and electron transport qualities. While strategies exist to improve these properties, and hence reduce charging times and enhance storage capacity, they are often expensive, difficult to implement on a large scale, and of only limited effectiveness. An alternative solution is the search for new materials with the desired atomic structures and characteristics. This is the strategy of a group of researchers who, utilizing ultra-bright x-rays from the U.S. Department of Energy’s Advanced Photon Source, identified and characterized two niobium tungsten oxide materials that demonstrate much faster charging rates and power output than conventional lithium electrodes.

Thin films are ubiquitous in computer chips and other electronic devices. Researchers have recently begun tuning the properties of these films by growing them on substrates with different crystal structures. A particularly interesting case is the lanthanum-cobalt oxide, LaCoO3, or LCO for short. As a bulk crystal, LCO is not magnetic, but thin films of LCO grown on certain substrates exhibit ferromagnetic ordering. Previous attempts to explain this induced magnetism have been unable to incorporate the fact that the atomic arrangement, or crystal symmetry, of epitaxial LCO film is distinct from that of both its bulk phase and its substrates. This symmetry mismatch leads to additional structural distortions in LCO thin films, as observed in x-ray experiments performed at the U.S. Department of Energy’s Advanced Photon Source (APS) and elsewhere.

Portland cement concrete is all around us, in the sidewalks we walk on, the buildings we live and work in, and the roads our vehicles ride on. One of the most versatile and useful building materials ever created, it is so commonplace that we hardly ever think of it (unless we happen to trip and scrape our knees on it). Yet surprisingly, although we worry about carbon emissions from cars, airplanes, and power plants, this everyday, seemingly innocent material is also a hidden and largely ignored global warming culprit.

Humans can learn a lot from plants. With energy from the sun, protein catalysts in plants efficiently split water to generate oxygen, storing the energy as carbohydrates. Scientists would like to perform a similar trick, using solar energy to split water and produce hydrogen fuel. Hydrogen fuel burns clean, producing only water as a byproduct, but splitting water is not an efficient task for humans. Researchers have taken baby steps toward artificial photosynthesis, building solar-powered water-splitting catalysts in the laboratory, but so far these catalysts remain far less efficient than their vegetal counterparts. One reason it's difficult to improve catalytic efficiency is that scientists don't fully understand the catalysts’ water-splitting mechanism.

Inexpensive materials called MOFs, for metal-organic frameworks, pull gases out of air or other mixed gas streams, but fail to do so with oxygen. Now, a team that includes researchers from two U.S. Department of Energy (DOE) national laboratories has overcome this limitation by creating a composite of a MOF and a helper molecule in which the two work in concert to separate oxygen from other gases simply and cheaply. The results, achieved with an assist from the DOE’s Advanced Photon Source (APS) at Argonne, might help with a wide variety of applications, including making pure oxygen for fuel cells, using that oxygen in a fuel cell, removing oxygen in food packaging, making oxygen sensors, or for other industrial processes. The technique might also be used with gases other than oxygen as well by switching out the helper molecule.

Chemically the same, graphite and diamonds are as physically distinct as two minerals can be, one opaque and soft, the other translucent and hard. What makes them unique is their differing arrangement of carbon atoms. Polymorphs, or materials with the same composition but different structures, are common in bulk materials. Now a new study in Nature Communications that describes results from studies at synchrotron x-ray light sources, including two U.S. Department of Energy user research facilities, confirms they exist in nanomaterials, too.

Metal oxides such as titanium dioxide (TiO2) are fascinating and versatile substances that can be used in many applications, including photovoltaic devices, batteries, and other vital technologies. But the utility of a particular material for a particular purpose may be limited, and common techniques to chemically "fine tune" their properties to fit specific parameters, such as doping or surface coating, are not always practical or effective. A group of researchers from a diverse set of institutions decided to try a different strategy by cross-linking metal oxide molecules with boron to create clusters of hybrid networks with new chemical and electrical properties and then characterizing the material at the U.S. Department of Energy’s Advanced Photon Source. Their work, which was published in Nature Materials, opens possibilities for the precise tailoring of such materials for specific purposes.

Of the many amino acids essential for life, glycine has both the fewest number of atoms and the greatest known number of polymorphs (unique structural forms). Although scientists have long recognized that glycine displays multiple polymorphs, the exact structure of several of these forms has remained a mystery. Now a research team has uncovered the precise molecular arrangement of one of these mysterious structural phases, which they have dubbed glycine dihydrate, or GDH. The researchers deduced the structure of GDH by applying computational analysis to powder x-ray diffraction measurements collected at the U.S. Department of Energy’s Advanced Photon Source (APS) at Argonne National Laboratory.

Overview

High-energy X-ray diffraction (XRD) is a bulk structure characterization technique widely used in materials research taking advantage of the high penetration power into materials, large accessible q-range, and small correction factors. In situ measurements study materials under various conditions. Operando studies are essential for insights into structural changes in functional materials during operation with the goal of improving their performance. XRD can resolve phase identities and other features, like particle size, micro-strain, structural defects, etc. The beamlines operated by the Structural Science (SRS) group offer a wide range of in situ and operando powder XRD and total scattering measurement capabilities with sub-second temporal resolution. The beamlines operate in x-ray transmission geometry with monochromatic beams and area detectors. In addition, 11-BM utilizes an array of analyzer crystals and scintillators to achieve the highest resolution. Most recent developments include an in-line Raman system at 17-BM and 11-ID-B that allows simultaneous measurement of XRD/PDF and Raman spectroscopy data under controlled temperature and gas environments. 11-ID-B enables studies of surfaces and interfaces with an optional 1D vertical focusing on the order of a few micrometers.  11-ID-B utilizes a hexapod positioning stage to allow highly accurate control of sample orientation, enabling surface and interface scattering. 11-ID-C employs a heavy-load hexapod providing similar capabilities for heavy equipment up to 250 kg. The high-resolution 11-BM beamline now has the option to switch to an area detector for rapid checks on the sample status. The group has a strong emphasis on battery research, maintaining an electrochemistry facility which is accessible 24/7 for all APS users for cell preparation.
