Advances in Triboelectric Nanogenerators With Rotating Structure
The rotating TENG has been widely studied for its superiorities of simple structure, high efficiency, and stable output. This review introduced the four different principles of rotating TENG and offered a thorough summary for performance and application research through three‐level classification. Importantly, the current existing problems, challenges,

Traditional carbon materials show limited high‐temperature oxidation resistance, which becomes pronounced above 673 K and significantly restricts their practical applicability. To address this challenge, enhancing polarization loss and leveraging its negative temperature dependence to offset the temperature‐induced increase in conductance loss are ...

Sudan at War With Itself: Civilian Devastation in the Civil War
ABSTRACT A civil war is raging in Sudan between the Sudan Armed Forces (SAF) and the Rapid Support Forces (RSF) along with militia groups. Beginning on April 15, 2023, and continuing at least to this writing (October 15, 2025), civilian noncombatants have been subjected to bombings, beatings, torture, shootings, rape, and murder on a large scale. Since
