AbstractThis study demonstrates the controllable switching of skyrmion helicity using spin-orbit torque, enhanced by thermal effects. Electric current pulses applied to a [Pt/Co]3/Ru/[Co/Pt]3 multilayer stripe drive skyrmions in a direction opposite to the current flow. Continuous pulsing results in an unexpected reversal of skyrmion motion. Micromagnetic simulations reveal that skyrmions in the upper and lower ferromagnetic layers exhibit distinct helicities, forming a hybrid synthetic skyrmion.

AbstractNi-rich layered oxides (LiNixCoyMn1−x−yO2, x > 0.8, NCM) are technologically important cathode (i.e., positive electrode) materials for next-generation high-energy batteries. However, they face challenges in cycle stability and durability due to internal strain accumulation and particle fracture as the batteries cycle. Here we report a simple molten-salt-assisted synthesis route to introduce gradiently distributed pores into the polycrystalline NCM secondary particles.

AbstractElectronic systems and devices operating at significant power levels demand sophisticated solutions for heat dissipation. Although materials with high thermal conductivity hold promise for exceptional thermal transport across nano- and microscale interfaces under ideal conditions, their performance often falls short by several orders of magnitude in the complex thermal interfaces typical of real-world applications.

AbstractDielectric polymer composites for film capacitors have advanced significantly in recent decades, yet their practical implementation in industrial-scale, thin-film processing faces challenges, particularly due to limited biaxial stretchability. Here, we introduce a mechanochemical solution that applies liquid metal onto rigid dielectric fillers (e.g. boron nitride), dramatically transforming polymer-filler interface characteristics.

While 54 percent of global consumers expect to increase their cross-border spending over the next six to twelve months, they need flexibility and transparency in the digital payment experience to make that happen. In a report released today by leading global payments and financial platform Airwallex and Edgar, Dunn & Company, 77 percent of consumers also said they would abandon their cart if their preferred payment method was not offered.

History of PresentationA 43-year-old man presented to the emergency department with shortness of breath of 6 months’ duration. He previously played ice hockey regularly, but now experienced NYHA functional class III dyspnea. He had no associated chest pain, cough, orthopnea, or paroxysmal nocturnal dyspnea. His blood pressure was 114/82 mm Hg, heart rate was 105 beats/min, and oxygen saturation was 94% on room air.
