Researchers have discovered that ferroelectric fluids can harness an overlooked transverse electrostatic force (TEF) to rise over 80 mm, without magnets or high voltages. By exploiting the fluid’s spontaneous polarization and exceptionally high dielectric constant, they achieved a strong TEF, previously thought unattainable in conventional electrostatics. This breakthrough enables creation of a lightweight, magnet-free motor, opening possibilities for compact, energy-efficient actuators and suggesting a transformative approach to converting electrical energy into mechanical motion at low voltages.
Researchers have developed a novel Nickel-Cobalt bimetallic nanocomposite material. Its built-in dual electric field significantly enhances electromagnetic energy dissipation, achieving ultra-wideband absorption.
A highly efficient, wearable self-charging power system is reported, which consists of a triboelectric nanogenerator (TENG) with fabric coated by MXene paste as conductive layer and micro-supercapacitors (MSCs) with graphene films as electrode.
Super-resolution imaging is essential for visualizing fine biological structures beyond the diffraction limit. To advance this field, Scientists in Korea developed a super-resolution imaging system based on a novel multifocal metalens. This ultrathin metalens generates dense, uniform focal arrays optimized for image scanning microscopy (ISM), achieving twice the resolution of conventional wide-field (WF) imaging. The technique successfully revealed fine neuronal structures in brain organoids and is expected to open new avenues for advanced optical microscopy systems.
Persistent organic pollutants such as DDT and lindane still pollute the environment and affect humans decades after their use. ETH researchers have developed a new electrochemical process that completely dehalogenates these long-lived toxins and converts them into valuable industrial chemicals.
The method uses cheap equipment, prevents side reactions and could be used on contaminated landfills, soils or sludge. Mobile systems could be used on site in the future – an important step towards the remediation of contaminated sites and the creation of a sustainable circular economy.
