A new method to dynamically simulate groundwater table in land surface model VIC *

Progress in Natural Science, 2003
Abstract Soil moisture plays an important role in water and energy balance in land-atmospheric interaction, but is impacted directly by the groundwater table. Dynamic variation of the groundwater tablecan be described mathematically by a moving boundary problem. In this paper, the moving boundary problem is reduced to a fixed boundary problem through a

Role of Liquid Composition in the Transient Liquid Assisted Growth of Superconducting YBa2Cu3O7‐δ Films

Advanced Materials, EarlyView.
The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Regional Distribution of the VIC Model Parameters and Application in Ungauged Basins

Journal of Water Resources Research, 2012
构建覆盖安康流域的大尺度网格VIC分布式水文模型，利用有资料地区率定模型参数，分析VIC模型参数与气候和土壤因子的关系，探讨模型参数的地区分布规律。根据安康流域1980~1990年逐日实测数据，采用多元回归方法建立了参数移用公式，并用来推求无资料地区的水文模型参数。应用结果表明：移用公式在安康、褒河和岚河子流域的模拟效果较好，VIC模型率定期的确定性效率系数分别为91.41%、90.01%和86.55%，接近有资料地区参数率定的结果，可用于无资料地区的径流模拟。 A macro-scale VIC hydrological model for the Ankang basin is constructed and calibrated based on recorded data from 1980

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Resolving the Structural Duality of Graphene Grain Boundaries

Advanced Materials, EarlyView.
Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.
