Van Der Waals Force

Sails and keels, like airplane wings, exploit Bernoulli's principle. Aerodynamic and hydrodynamic insights help designers create faster sailboats.

Imagine a future where computers can learn and make decisions in ways that mimic human thinking, but at a speed and efficiency that are orders of magnitude greater than the current capability of computers.

Rice University physicists have discovered a phase-changing quantum material—and a method for finding more like it—that could potentially be used to create flash-like memory capable of storing quantum bits of information, or qubits, even when a quantum computer is powered down.

MIT scientists have tackled key obstacles to bringing 2D magnetic materials into practical use, setting the stage for the next generation of energy-efficient computers.

By intercalating protons into van der Waals ferromagnet Cr1.2Te2 nanoflakes, a group of researchers successfully induced a room-temperature magnetic phase transition from ferromagnetism to antiferromagnetism.

A new study led by Vinod M. Menon and his group at the City College of New York shows that trapping light inside magnetic materials may dramatically enhance their intrinsic properties. Strong optical responses of magnets are important for the development of magnetic lasers and magneto-optical memory devices, as well as for emerging quantum transduction applications.

Optimum performance of upcoming thermochemical energy storage and other technologies depends on proper applications of the principles that underpin salt ion hydration. Now, researchers from Japan have solved a long-standing puzzle of ion hydration that will be useful in electrolyte design for such technologies.

A common metal paper clip will stick to a magnet. Scientists classify such iron-containing materials as ferromagnets. A little over a century ago, physicists Albert Einstein and Wander de Haas reported a surprising effect with a ferromagnet. If you suspend an iron cylinder from a wire and expose it to a magnetic field, it will start rotating if you simply reverse the direction of the magnetic field.

Novel, ultrathin nanomaterials exhibit remarkable properties. If you stack individual atomically thin layers of crystals in a vertical assembly, for example, fascinating physical effects can occur. For instance, bilayers of the wonder material graphene twisted by the magic angle of 1.1 degrees may exhibit superconductivity. And researchers are also focusing their attention on bilayer semiconducting heterostructures…

Graphene's 2D nature, single molecule sensitivity, low noise, and high carrier concentration have generated a lot of interest in its application in gas sensors. However, due to its inherent non-selectivity, and huge p-doping in atmospheric air, its applications in gas sensing are often limited to controlled environments such as nitrogen, dry air, or synthetic humid air.

A new study led by Dai Qing's team from the National Center for Nanoscience and Technology (NCNST) of the Chinese Academy of Sciences (CAS) and Javier Abajo from the Institute of Photonic Sciences (ICFO) in Spain has shown a gate-tunable nanoscale negative refraction of polaritons in the mid-infrared range through a van der Waals heterostructure of graphene and molybdenum trioxide.

Introduction Quantum researchers require access to different types of quantum hardware from digital, also known as gate-based, quantum processing units (QPUs) to analog devices that are capable of addressing specific problems that are hard to solve using classical computers. Today, Amazon Braket, the quantum computing service from AWS, continues to deliver on its commitment to […]

MIT researchers created a technique for precisely arranging nanoparticles onto surfaces in arrays with arbitrary shapes that does not cause damage to the material's surface. The scalable technique could help make higher-performance devices like lasers, LEDs, sensors, and actuators.

Chemists have discovered that pointy gold tetrahedrons self-assemble into 2D chiral superlattices. The structures could be useful metamaterials.

As our devices become smaller, faster, more energy efficient, and capable of holding larger amounts of data, spintronics may continue that trajectory. Whereas electronics is based on the flow of electrons, spintronics is based on the spin of electrons.

Atoms are fed into the system just like a pitching machine.

The third dimension may be responsible for preventing electronics from becoming thinner, tinier and more flexible, according to an international collaboration that developed a way to manufacture new, idealized two-dimensional semiconductor materials. They published their approach on June 3 in Nano Research.

Researchers have developed a unique design of ultrathin films for highly flexible yet mechanically robust bioelectronic membranes that could pave the way for diagnostic on-skin sensors that fit precisely over the body's contours and conform to its movements.

Nate Oats will once again need to do a good job of bringing good transfer portal talent to the Alabama basketball team.
