Ptychography implemented with coherent high-harmonic (HHG) sources enables high-resolution, high-fidelity imaging of nanostructures and biosystems. However, when driven by mid-infrared lasers to generate light at higher photon energies, HHG inherently produces a broadband quasi-continuum, which is less suited for coherent imaging compared with a single harmonic order. Consequently, experiments ty…

Ferroelectric materials such as hafnium zirconium oxide (HZO) are likely to form the basis of a next-generation memory technology.  For instance, replacing the conventional gate dielectric in a field-effect transistor (FET) with HZO can form a ferroelectric FET, or FeFET.  Chris Regan’s group at UCLA has been working with Suman Datta’s group at Georgia Tech . . .

Integrated cryogenic electron microscopy (cryoEM) and cryogenic electron tomography (cryoET) approach, advanced through NSF’s STROBE, a National Science Foundation Science and Technology Center, enables unparalleled resolution for complex cellular structures like the flagellar doublet microtubules (DMT) of Trypanosoma brucei. This parasite causes African sleeping sickness, affecting millions. The…

Lensless imagers can make cameras far thinner than conventional optics and can compress rich scene information into a single measurement. But the same optical multiplexing that enables those advantages can also scramble a scene so strongly that reconstruction loses the information it needs. We address this design problem by evaluating lensless encoders through mutual information . . .

Currently, host-guest interactions in metal–organic frameworks (MOFs) are mainly understood via theoretical simulations, bulk characterization techniques, and x-ray diffraction, all of which can average out information related to defects, interfaces, and spatial heterogeneity among adsorption sites. Since these structural features can directly impact the functionality of MOFs we applied local pro…

Amorphous materials — solids lacking long-range periodic order — are vital to technologies spanning thin-film electronics, solar cells, phase-change memory, magnetic components, biomedical devices, and quantum hardware. Yet their structural disorder has long prevented full three-dimensional (3D) atomic mapping. Despite major advances in probing short- and medium-range order, experimentally determ…

Researchers from UCLA have used ultrafast electron diffraction to reveal a hidden electronic phase that cannot be reached by ordinary heating. The study focuses on 1T-TaS₂, a layered material in which electrons naturally organize into a periodic charge pattern known as a charge density wave. Theory has long suggested that such ordered electronic patterns could . . .

Dichroic X-ray tomography resolves a sample's 3D crystal orientation (linear dichroism) or magnetization (circular dichroism) from projections taken at varying beam directions and polarizations. Like most tomographic methods, its reconstruction assumes that absorption along a ray is a simple line integral of a local, voxel-independent absorption coefficient. This work showed that for linear dichr…

Colloidal semiconductor nanocrystals (NCs) offer remarkable tunability of optoelectronic properties through synthetic control of their size, shape, and composition. An emerging strategy is the synthesis of III-V nanocrystals in molten salts, where high temperatures and unique redox chemistry enable the production of highly crystalline binary, ternary, and quaternary semiconductor NCs. A notable e…
