The development of an idea into a commercial product can take decades, a timeframe that allows contributions from multiple generations of scientists and requires investment in basic research. Collaborative research between the ALS and Hewlett Packard Labs has advanced the memristor, a device that can store information using little to no power. Read more »
Tunable Ferromagnetism in a 2D Material at Room Temperature
Researchers combined soft x-ray spectroscopy and microscopy to demonstrate the tunable ferromagnetic characteristics of a two-dimensional layered material at room temperature. The results open up exciting opportunities for the use of such materials in low-power spintronics, high-density magnetic storage, and flexible electronics. Read more »
Ordered Magnetic Patterns in a Disordered Magnetic Material
Scientists have confirmed the presence of chirality, or handedness, in nanometers-thick samples of amorphous (noncrystalline) multilayer materials. The chirality—which potentially could be exploited to transmit and store data in a new way—was observed in the domain walls between neighboring regions of opposite spin. Read more »
A 2D Lattice of Molecular Qubits for Quantum Computing
Researchers developed a way to build a 2D lattice of molecular-spin qubits (quantum bits of information), with control over qubit orientation and localization. The work enables the integration of molecular quantum-information hardware into the scalable, robust, solid-state architectures needed for performing quantum computation. Read more »
Oxygen Vacancies Matter in the LaNiO3 Metal–Insulator Transition
Electronic structure measurements using x-ray absorption spectroscopy suggest that oxygen vacancies contribute to the metal–insulator transition in ultrathin films of LaNiO3. The results give scientists another “knob” to turn to tune this important transition, which could be useful for making advanced electronic devices. Read more »
A Designed Material Untangles Long-Standing Puzzle
The origin of the metal-to-insulator transition in a key material system was revealed by nanostructures designed to decouple simultaneous phase transitions. This approach could lead to new materials with emergent physics and unique electronic properties, supporting broader research efforts to revolutionize modern electronics. Read more »
A facile route for the synthesis of heterogeneous crystal structures in hierarchical architectures with vacancy-driven defects via the oriented attachment growth mechanism
TiO2 nanorod arrays based on substrates with heterogeneous crystal structures and remarkable crystalline stability have potential as promising photocatalysts. Researchers synthesized a 1D anatase/rutile heterogeneous TiO2 crystal structure in a hierarchical architecture by forming hybrid organic–inorganic interfaces in a solution-based environment.

The Electronic Structure of a “Kagome” Material
Scientists have verified exotic electronic properties predicted to emerge in a ferromagnetic material with “kagome” (trihexagonal) lattice symmetry. The greater understanding of kagome materials afforded by this work helps open up a new path toward goals such as ultralow-power electronic devices and quantum computing. Read more »
From Moon Rocks to Space Dust: Berkeley Lab’s Extraterrestrial Research
Berkeley Lab has a well-storied expertise in exploring samples of extraterrestrial origin. This research—which has helped us to understand the makeup and origins of objects within and beyond our solar system—stems from long-standing core capabilities in structural and chemical analyses and measurement at the microscale and nanoscale.

Non-Crystal Clarity: Scientists Find Ordered Magnetic Patterns in Disordered Magnetic Material
Scientists have confirmed the presence chirality, or handedness, in nanometers-thick samples of amorphous (noncrystalline) multilayer materials. The chirality—which potentially could be exploited to transmit and store data in a new way—was observed in the domain walls between neighboring regions of opposite spin. Read more »
