Clustering of Floating Tracer Due to Mesoscale Vortex and Submesoscale Fields

Geophysical Research Letters, 2020
Floating tracer clustering is studied in oceanic flows that combine both a field of coherent mesoscale vortices, as simulated by a regional, comprehensive, eddy‐resolving general circulation model, and kinematic random submesoscale velocity fields.

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

Advanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Analysis of Mesoscale Characteristic of Hailstorm Weather in Xinjiang

Advances in Geosciences, 2016
针对2007~2016年新疆30场冰雹天气11种强对流参数的归纳分析表明，冰雹天气发生时，K指数大于30℃，沙氏指数小于2℃，湿对流有效位能大于150 J/kg，最大上升速度超过10 cm/s，对流抑制有效位能0~30 J/kg，风暴强度指数230~280、抬升凝结高度超过600 m，平衡高度230~700 m，自由对流高度550~1000 m。利用FY-2D红外云图和NECP再分析资料，采用卫星云图数字处理方法和低通滤波技术，对南疆西部一次冰雹和暴雨天气的对比分析表明，冰雹过程中TBB低且梯度强，经过中尺度滤波后，冰雹和暴雨天气均由中-β尺度引发，冰雹天气气象要素的变化强度强于暴雨天气。 The analysis on 11 convection parameters of 30 ...

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Eutectozymes as Soft Hybrid Materials for Advanced Biocatalysis

Advanced Materials, EarlyView.
Eutectozymes are sustainable hybrid materials that embed a GOx–HRP cascade within hydrophobic eutectogels featuring a dual supramolecular–covalent network. This architecture preserves native enzyme structure and stability, enables efficient heterogeneous biocatalysis in aqueous media, and positions eutectogels as robust platforms for next‐generation ...

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

Advanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

Advanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.
