The Tradeoff behind Optimal 3-Fold (C,N)-Coordinated Single-Atom Catalysts
Abstract Single-atom catalysts have emerged as a powerful class of catalytic materials, maximizing atom efficiency through isolated metal centers. However, their design inherently relies on a delicate balance between stability and catalytic performance. In this work, we investiga...

Objectives: To evaluate sealing ability of root canals obturated with bioceramic-impregnated gutta percha cone (BCC) or gutta percha (GP), with bioceramic sealer (BCS) or AH Plus (AH; Dentsply-Maillefer), in roundly-prepared canals using matched single-cone technique, based on ba...

Abstract Predictive domain wall nucleation, propagation, and pinning is achieved by He⁺ ion irradiation of spin-orbit torque thin film devices. Engineering the magnetic anisotropy landscape with nm precision, we demonstrate that non-irradiated gaps as small as 10 nm can act as re...

Noncollinear kagome magnet driven by giant antisymmetric exchange
Kagome lattices host exotic phenomena such as quantum spin liquids, topological Weyl nodes, and flat bands. The kagome ferromagnet Co3Sn2S2 has been a focus of debate due to conflicting reports on its magnetic character. Here, using weakly perturbative probes—primarily neutron sc...

Type-II-like ultrafast demagnetization behavior in NiCo2O4 thin films
Rare-earth-free ferrimagnetic oxides are emerging as attractive platforms for investigating ultrafast spin dynamics. Here, we study the photoinduced magnetization dynamics of epitaxial NiCo2O4 (NCO) thin films by the time-resolved magneto-optical Faraday effect using two independ...
