Wet Ball Milling Synthesis of Iron Oxide Nanoparticles for High‐Efficiency, Controllable Magnetic Hyperthermia in Ovarian Cancer

open access: yesAdvanced Materials Technologies, EarlyView.
A wet ball‐milling method is presented to synthesize iron magnetic nanoparticles and evaluate their magnetic hyperthermia performance. Optimized particles (∼270 nm, Ms ∼114 emu/g) achieve ∼50°C heating under clinically safe alternating magnetic fields, while pulsed‐field operation enables controlled temperature regulation (∼30°C).

Fully 3D‐Printed Wave‐Wound Electromagnetic Motors

open access: yesAdvanced Materials Technologies, EarlyView.
This work presents the first fully 3D‐printed wave‐wound electromagnetic motors, which are created using conductive nanoparticle inks, carbon‐filled nylon polymers, and surface mount components. These motors can achieve a stall torque of 7.62N·mmA−1$7.62 \nobreakspace N{\cdot }mm A^{-1}$ and efficiency of 28.2 %, which approaches the performance of ...

The wickedness of citizen science, law and planetary health: grappling with trust, democracy and representation

open access: yes, 2022
The health of our planet is at risk and so are we. This is widely recognized as a highly urgent matter. National and international policy and go- vernance bodies expect that citizen science can help address this urgency, e.g.

Stretchable and Strain‐Tolerant Gold‐Coated Fibrous Biosensor for Superoxide Anion Monitoring

open access: yesAdvanced Materials Technologies, EarlyView.
A breathable, stretchable gold nanomesh–TPU fiber platform is developed via controlled electroless deposition, enabling uniform through‐thickness conductivity while preserving porosity. Functionalized with superoxide dismutase, the system achieves selective, real‐time electrochemical detection of superoxide with high sensitivity, mechanical durability,

Solid Particle‐Liquid Metal Mixtures for Robust High‐Current Interconnects in Stretchable Electronics and Soft Robotics

open access: yesAdvanced Materials Technologies, EarlyView.
Metallic microparticles dispersed in liquid metal interconnects mitigate electromigration‐induced failure by reconfiguring internal current density distributions. These fillers facilitate the growth of a robust, protective gallium oxide shell at elevated temperatures, shifting the failure threshold toward a thermal limit.

Charged Clouds of Ionized Gas Emerge from Tribocharging Grains

open access: yesThe Planetary Science Journal
If two solid particles collide, charge is exchanged. However, this transfer is not restricted to the surface of the particle. Ions are also dispersed into the environment. They form a charge cloud around the particle.

Luminescence and Photochromism in Lanthanide‐Doped Hackmanites

open access: yesAdvanced Optical Materials, EarlyView.
Lanthanide‐doped lithium hackmanite derivatives are prepared utilizing a doped LiAlSiO4 precursor to modify luminescent and photochromic properties. Upon UV excitation, europium doping results in green Eu2+ persistent luminescence from shallow traps. Contrarily, samarium doping induces unusual near‐infrared photochromism.
