    Nbits pinned to an LC defect line. The local nematic director field n(r), indicated by cylindrical bars, rotates by π along closed curves encircling the defect line (black). The director field is colored by its out-of-plane component, nz(r), while xy-planes are colored by the director’s azimuthal orientation nϕ(r) relative to the x axis. The near-field director profile (red) close to the defect line defines the nbit state. The vertical direction may be interpreted as either a spatial or a time dimension.

    The new moisture-driven electricity generation device invented by NUS researchers capitalises on the difference in moisture content of the wet and dry regions of the carbon-coated fabric to create an electric current. Sea salt is used as a moisture absorbent for the wet region.

    Researchers have developed a new moisture-driven electricity generation device made of a thin layer of fabric, sea salt, carbon ink, and a special water-absorbing gel. The device works by keeping one end of the fabric dry, while the other end is perpetually wet. The difference in moisture content of the wet and dry regions of the carbon-coated fabric creates an electric current...

    Using photons and electron spin qubits, researchers demonstrated atomic-scale sensing for use in NMR, and by controlling nuclear spin, creating nuclear qubits with longer coherence times than previously used electron spin qubits.

    By using photons and electron spin qubits to control nuclear spins in a 2D material, researchers at Purdue University have opened a new frontier in quantum science and technology, enabling applications like atomic-scale nuclear magnetic resonance spectroscopy, and to read and write quantum information with nuclear spins in 2D materials.

    As published Monday (Aug...

    A schematic diagram of the method for determining the relationship between the morphology and piezoelectric performance of fiber components

    A research team led by Lim Sang-kyoo, senior researcher of the Division of Energy Technology at DGIST (President Kuk Yang) developed a piezoelectric polymer/ceramic composite fiber with a cross-sectional form that is uniformly controlled to allow the use of energy harvesting technologies that can recycle energy wasted or consumed in everyday life.

    Piezoelectric fiber can produce electrical energy through the piezoelectric effect of the material and drive wearable electronic devices through the movement of the wearer...
