Rethinking of geological disaster control at the anniversary of the Wenchuan Earthquake

Lu Yaoru

Strategic Study of CAE 2009, Volume 11, Issue 6,   Pages 36-43

Abstract:

The big Wenchuan Earthquake has passed for a year, but the huge disaster caused by the earthquake cannot be forgotten yet. The scientific development view should be better carried out and the earthquake mechanism should be analyzed thoroughly, so that effective scientific reference can be provided for consideration of the prevention and reduction of future disaster.

Undrained seismic bearing capacity of strip footing adjacent to a heterogeneous excavation

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 4,   Pages 566-583 doi: 10.1007/s11709-023-0905-x

Abstract: The analysis of the bearing capacity of strip footings sited near an excavation is critical in geotechnics. In this study, the effects of the geometrical features of the excavation and the soil strength properties on the seismic bearing capacity of a strip footing resting on an excavation were evaluated using the lower and upper bounds of the finite element limit analysis method. The effects of the setback distance ratio (L/B), excavation height ratio (H/B), soil strength heterogeneity (kB/cu), and horizontal earthquake coefficient (kh) were analyzed. Design charts and tables were produced to clarify the relationship between the undrained seismic bearing capacity and the selected parameters.

Precursor-driven structural tailoring of iron oxychloride for enhanced heterogeneous Fenton activity

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 10,   Pages 1533-1543 doi: 10.1007/s11705-023-2330-z

Abstract: Iron oxychloride (FeOCl) is a unique layered material with tunable electronic properties. The conventional synthetic route of chemical vapor transition involves a thermodynamics-driven gas–solid interfacial reaction which often generates macroscopic crystals with stable facets. In this study, through analyzing the effects of the synthetic parameters on the FeOCl synthesis, we discovered the dominant contribution of the α-Fe2O3 precursors on the chemical property of the FeOCl product, and subsequently developed a highly-controllable synthetic route of tailoring the FeOCl structures into small sizes and exposed high-energy facets via a facile and scalable mechanical-chemical approach. The synthesized products could be systematically tuned by the ball-milling conditions of the α-Fe2O3 precursors. With increased milling time, the FeOCl crystallites demonstrated reduced sizes and more exposed (110) facets. Intriguingly, these small-sized FeOCl catalysts exhibited much faster Fenton-like kinetics than the pristine macroscopic FeOCl materials. Specifically, FeOCl catalysts with a 12-hour milling time showed nearly 39 times higher efficiency toward phenol degradation than the pristine FeOCl. The structure-reactivity relationship was further elucidated using the combinatory analysis via density functional theory calculation, electron paramagnetic resonance and radical quenching probe experiments. This work provides a rationale for tailoring the surface structures of FeOCl crystallites for potential applications in environmental catalysis.
