Multiscale Symmetry Breaking Enables Tunable Magnetic Anisotropy and Damping in Co 2 FeAl Thin Films

ABSTRACT The ability to simultaneously engineer magnetic stability and spin dissipation remains difficult to realize in scalable metallic thin films. Here, we show that multiscale symmetry breaking provides a route to achieve this control in polycrystalline Co 2 FeAl films withou...

Dynamic Covalent Porous Networks Enabling Synergistic Microwave Attenuation

Lightweight, adaptive, and porous microwave (MW) absorbers with reprocessability are highly desirable for next-generation portable electronics and sustainable electromagnetic interference (EMI) shielding systems. Herein, we report a one-pot strategy for fabricating three-dimensio...

Dynamic responses of rubble mound breakwaters reinforced with geogrid-wrapped slopes and sheet piles under sequential earthquake loading

Rubble mound (RM) breakwaters are widely used to protect coastlines from sea wave actions; however, past seismic events have exposed their vulnerability to catastrophic failure, most often driven by foundation soil instability. Despite the critical importance of this problem, exp...

Impact of He+ ion irradiation on the domain wall dynamics in Pd/Co/Pd trilayers with perpendicular magnetic anisotropy

Heavy metal/ferromagnetic-based heterostructures with perpendicular magnetic anisotropy (PMA) are prototypes for domain wall (DW)-based spintronic devices. We explored the impact of He + ion irradiation on the bubble DW dynamics in Pd/Co/Pd trilayers with PMA. The effective magne...

Electrochemical Reduction of CO2 Using a Metal-Free Polymer Catalyst: Synergy of Pyrrole and Quinone Interfacial Sites

Abstract The electrocatalytic reduction of CO2 to value-added chemicals leads to a combined solution to address carbon dioxide emission and the demand for sustainable energy storage. Although metal catalysts have dominated and defined a benchmark in the field of electrochemical C...

Influence of MICP on unsaturated soil properties and its application as bio-engineered slope covers on stability of slopes under varying rainfall conditions

Rapid expansion and increase in infrastructural demand for the connectivity has led to increase in construction of roads in mountainous region across the world. However, the presence/ formation of steep soil slopes and cuts along roadways pose a significant geotechnical challenge...

Geofence Compliance Maneuvers for Fixed-Wing Uncrewed Aerial Vehicles

Geofencing is essential for ensuring the safe and regulated operation of uncrewed aerial vehicles (UAVs) within designated airspaces. For fixed-wing UAVs, which operate under roll angle and roll rate limitations, the early detection of potential geofence boundary violations and t...

The Impact of Fronts and Eddies Under Various Melt Conditions on Antarctic Ice Shelves

Abstract Ocean eddies are observed beneath Antarctic ice shelves, yet their role in regulating basal melting remains unclear. We use nonhydrostatic Large‐Eddy Simulations that resolve eddies and boundary‐layer turbulence to examine a baroclinically unstable salinity front that br...

Transformative Materials Research: Defining Conceptual Change across Scales

Abstract What qualifies as transformative materials research? In this Viewpoint, we use “transformative” to denote work that forces revision of underlying assumptions, enables generalization across systems, or reveals regimes inaccessible to existing frameworks. The term is widel...

Vortex dynamics during pinch-off of micro-droplets

Micro-droplets are extensively used in chemical, biological and medical research, primarily for conducting various tests on samples, including living organisms, using a microfluidic framework. Recent studies have shown that the physiology of bacteria can be significantly altered...

A circular carbon fiber composite architecture enabled by synergistic multi-dynamic networks

The pervasive use of carbon fiber-reinforced epoxy (CFRE) laminates in aerospace and marine engineering is hindered by the permanent nature of conventional thermoset matrices, which precludes self-healing and end-of-life circularity. Furthermore, suboptimal interfacial bonding be...
