MoS 2 Grain Boundary-Supported Single-Atom Catalysts for Efficient Electrocatalytic CO 2 Conversion to CO

Yuxing Lin, Meijie Wang, Yaowei Xiang, Lei Li et autres

Developing high-efficiency single-atom catalysts (SACs) is essential for the carbon dioxide reduction reaction (CO 2 RR) to produce fuels and chemicals, yet achieving optimal performance remains challenging. In this work, we applied a grain boundary (GB) strategy to rationally design a series …

First Experimental Constraint on the Scalar Current in the $D^{0(+)}\to \bar K\ell^+ν_{\ell}$ Transition

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

Using 20.3 fb$^{-1}$ of $e^+e^-$ collision data taken at the center-of-mass energy of $\sqrt{s}=3.773$ GeV, we report the first experimental constraint on the scalar current in the $D^{0(+)}\to \bar K\ell^+ν_{\ell}$ transitions, based on a simultaneous fit to the first measured forward-backward asymmetries …

Search for $ψ_0(4360)\rightarrow ηψ(2S)$ through the process $e^+e^- \rightarrow ηηψ(2S)$

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

Using data samples corresponding to an integrated luminosity of 0.9~fb$^{-1}$ collected with the BESIII detector operating at the BEPCII storage ring at the center-of-mass energies of 4.84, 4.92, and 4.95~GeV, we search for the exotic charmonium-like state with quantum numbers $J^{PC}=0^{--}$, $ψ_0(4360)$, …

Precise measurements of $D^0 \to K^-\ell^+ν_\ell$ and $D^+ \to \bar K^0\ell^+ν_\ell$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

Using $e^+e^-$ collision data corresponding to an integrated luminosity of 20.3 fb$^{-1}$, collected at the center-of-mass energy of 3.773 GeV with the BESIII detector, we present precise measurements of $D^0 \to K^-\ell^+ν_\ell$ and $D^+ \to \bar K^0\ell^+ν_\ell$ ($\ell=e,μ$) decays. The branching fractions …

Pyrene-based fluorescent molecularly imprinted polymer for the rapid and selective detection of oxytetracycline based on the inner filter effect

Tianyi Zhu, Jian (Jeff) Zhang, Danyi He, Yiwen Yang et autres

-allyl-4-(pyren-1-yl) butanamide (Al-Py), a new alkenyl functional monomer, was synthesized from 1-pyrenebutyric acid as the raw material through a simple synthesis process. Py-FMIP was then obtained with Al-Py as a functional monomer and OTC as a template molecule. The absolute fluorescence quantum …
