Driving Multi‐Step Regioselectivity in On‐Surface Polymer Synthesis by Molecular Coverage
Angewandte Chemie, EarlyView.Regioselective polymerization of dicyclopentaanthracene on Au(111) can be controlled by tuning molecular coverage. Low coverage yields 1D polymers, medium coverage produces quasi‐1D staircase polymers, and higher coverage drives 2D porous networks.

The Effect of Obliquity of Slip in Normal Faults on Distribution of Open Fractures
Frontiers in Earth Science, 2019 Close to surface, cohesive rocks fail in extension, which results in open fractures that can be several tens of meters wide, so-called massively dilatant faults. These open fractures make fault slip analysis in rifts challenging, as kinematic markers are

International Journal of Speleology, 2016 Tube-fed structure occurs as a general phenomenon in Tengchong basic lavas, such as lava tubes, lava plugs and tube-related collapse depressions. We deduced the development of Laoguipo lava flows, which is the longest lava tube (Jingfudong lava tube ...

Applied Sciences, 2022 Many ancient landslides in the upper reaches of the Jinsha River seriously threaten the safety of residents on both sides of the river. The river erosion and groundwater infiltration have greatly reduced the stability of the ancient landslides along the ...

The evolution of plate tectonics
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018 To understand how plate tectonics became Earth's dominant mode of convection, we need to address three related problems. (i) What was Earth's tectonic regime before the present episode of plate tectonics began?

Observing eruptions of gas-rich compressible magmas from space
Nature Communications, 2016 Satellite observations are an important tool in volcano monitoring, but observations such as ground deformation and gas emissions are treated independently. Here, the authors present a model coupling them through their link to magma volatile contents and

Remote Sensing, 2022 The rock mass along the Jinsha River is relatively broken under complex geological action. Many ancient landslides were distributed along the Jinsha River in Gongjue County, which is very dangerous under the action of gravity, tectonic stress and river ...
