Hace 2 días · Hybrid microresonators have served an intriguing platform for fundamental research and applied photonics. Here, we study the plasmonics-engineered coupling between degenerate optical whispering gallery modes, which can be tuned in a complex space featuring the dissipative strong, dispersive strong, and weak coupling regimes. Experimentally, the engineering of a single plasmonic resonance to a ...
Hace 20 horas · An approach is presented that utilizes synergistic photoredox and copper catalysis to achieve efficient C(sp3)−C(sp3) cross-coupling of alkyl N-hydroxyphthalimide esters, which can be easily obtained from alkyl carboxylic acids, with diborylmethyl species, providing a series of C(sp3)-rich gem-diborylalkanes with 1°, 2°, and even 3° β positions.
Hace 4 días · Transition-metal catalyzed cross-electrophile coupling (XEC) has become a prominent method for synthesizing molecules, attracting significant attention in the field 1,2,3,4,5,6.These reactions ...
Hace 1 día · A beamwidth (BW) and beam direction (BD) reconfigurable antenna based on multi-mode parasitic coupling is proposed. Two pairs of metal strips connected by only two positive-intrinsic-negative diodes are added as parasitic structures over the driven element, a circular microstrip patch, constituting a simple antenna design.
Hace 3 días · This letter presents a broadband resonator-based in-band decoupling concept for base station (BS) applications, addressing the deteriorated radiation performance resulting from the strong in-band mutual coupling. The baffles, featuring asymmetric periodic split-ring resonators (SRRs) and a metal strip, are developed to block mutual coupling between antenna array elements. To better provide ...
Hace 1 día · The ability to switch between ferromagnetic (FM) and antiferromagnetic (AFM) coupling in a material would increase the spintronic applications. To contribute, we focus on the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between two magnetic impurities situated on the strained and gapped topological crystalline insulating SnTe(001) surface. By considering an in-plane strain and gap, we ...
Hace 4 días · Contrary to the widely accepted attempt of using a sintering dense ceramic electrolyte to realize dendrite-free deposition, we report a coupling architecture of ion-conducting-Li 3 PO 4-Li 3 N interphase with lithiophilic-solid-oxide-electrolyte interlayer for Li-metal anode using a reactive lithiophilic solid oxide electrolyte (RLSE) rather than dense ceramics.
