Manipulating Charge Dynamics in Carbon Nitride by Carbon Dot Doping for Efficient Photocatalysis

Advanced Science, EarlyView.
A series of carbon dot (CD) doped graphitic carbon nitride (g‐C3N4) materials have been rationally synthesized, which exhibited different photophysical properties, excitonic behaviors, and photocatalytic degradation activities. It provides valuable insights to deepen the understanding of exciton dynamics based on g‐C3N4 materials, and rational design ...

Enhanced p–d Orbital Coupling in Unconventional Phase RhSb Alloy Nanoflowers for Efficient Ammonia Electrosynthesis in Neutral Media

Angewandte Chemie, EarlyView.
Ultrathin rhodium–antimony alloy nanoflowers with unconventional 2H phase were controllably synthesized via a facile one‐pot method. Benefitting from the enhanced electronic interaction by p–d orbital coupling, the prepared catalyst delivered an efficient ammonia electrosynthesis capacity in neutral media.

Diurnal and semidiurnal cyclicity of Radon (222Rn) in groundwater, Giardino Spring, Central Apennines, Italy [PDF]

, 2018
Understanding natural variations of Rn (222Rn) concentrations is the fundamental prerequisite of using this radioactive gas as a tracer, or even precursor, of natural processes, including earthquakes. In this work, Rn concentrations in groundwater were

Porous Aromatic Framework with Multifunctional Sites for Effective Recovery of Various Trace Iodine Species From Water

Advanced Science, EarlyView.
A PAF adsorbent with multifunctional sites framework is developed for the recovery of environment iodine. Benefiting from the high density and accessibility of the favorable Coulomb interaction sites for iodide (I3− and I−) as well as the charge transfer sites for iodine molecules (I2), the PAF adsorbent realizes recording adsorption capacity for ...

Two‐Step Tandem Catalysis for High‐Efficiency Ammonia Synthesis Via Nitrate Reduction on Anion‐Intercalated CoNi LDH and Cu/Cu2O

Advanced Science, EarlyView.
By integrating Cu/Cu2O and CoNi LDH, tandem kinetic descriptors, including a volcano curve, are employed to predict rate constants, facilitating ideal kinetic matching for efficient ammonia synthesis. The highest ammonia yield (1.12 mmol cm−2 h−1) and Faraday efficiency (99.78%) are achieved by rate matching between Cu/Cu2O and MoO4‐CoNi LDH.

Numerical simulation of zonal disintegration of surrounding rock in the deep‐buried chamber

Deep Underground Science and Engineering, Volume 1, Issue 2, Page 174-182, December 2022., 2022
Based on the finite difference software FLAC3D, the numerical simulation of cavern surrounding rock under different working conditions was carried out by using Bilinear Strain‐Softening Ubiquitous‐Joint Model (Subi). The effects of buried depth, cohesion and internal friction angle of surrounding rock on the discontinuous deformation are analyzed, and ...
