Integrating Machine Learning With Constant‐Potential Simulation to Unravel Charge‐Transfer Mechanisms in Electrochemical Nitrogen Fixation

open access: yesAdvanced Science, EarlyView.
Integrating interpretable machine learning with the fixed‐potential method reveals a novel mechanism: the catalytic activity of the electrochemical nitrogen reduction reaction is governed by partial charge transfer, induced by variations in the intermediate potential of zero charge under constant potential.

Spectroscopy of $^{18}$Na: Bridging the two-proton radioactivity of $^{19}$Mg

open access: yes, 2011
The unbound nucleus $^{18}$Na, the intermediate nucleus in the two-proton radioactivity of $^{19}$Mg, was studied by the measurement of the resonant elastic scattering reaction $^{17}$Ne(p,$^{17}$Ne)p performed at 4 A.MeV. Spectroscopic properties of the

Nanozymes for Liver Disease Therapy: Advances in Catalytic Activity, Targeting Strategies, and Clinical Translation

open access: yesAdvanced Science, EarlyView.
Nanozymes, as enzyme‐mimicking nanomaterials, exhibit unique catalytic properties for the treatment of liver diseases. By regulating redox homeostasis, modulating immune responses, and enabling targeted delivery, nanozymes overcome the limitations of natural enzymes.

Long‐term prognosis is associated with residual disease after neoadjuvant systemic therapy but not with initial nodal status

open access: yesBJS (British Journal of Surgery), EarlyView., 2020
This long‐term follow‐up study determined survival rates in a Swedish national cohort of 417 patients with breast cancer who all had neoadjuvant systemic therapy (NAST). Sentinel lymph node biopsy (SLNB) was performed before NAST in clinically node‐negative and after NAST in clinically node‐positive patients.

Highly Efficient Extraction of 212 Pb/212Bi from the Decay Chain of 232Th‐Based on Anion Exchange in Bromide Medium

open access: yesAdvanced Science, EarlyView.
This work provides an effective strategy for selectively extracting 212Pb and 212Bi from the decay chain of 232Th as well as its mechanism illustration. Using the novel strategy, 2.07 MBq of 212Pb is successfully separated from 232Th and its daughters, which enables the supply of 212Pb/212Bi directly from the abundant natural thorium resource to be ...
