Numerical Investigation on Impact Erosion of Aeolian Sand Saltation in Gobi

Atmosphere, 2023
Sand drift erosion is common on aeolian landforms, particularly in the Gobi desert where sand drift is often quite strong. Sand drift erosion can lead to many types of hazards, including severe crop loss, structural damage to buildings or infrastructure,

Centennial- to millennial-scale hard rock erosion rates deduced from luminescence-depth profiles [PDF]

, 2018
The measurement of erosion and weathering rates in different geomorphic settings and over diverse temporal and spatial scales is fundamental to the quantification of rates and patterns of earth surface processes. A knowledge of the rates of these surface

Lateral Marsh Edge Erosion as a Source of Sediments for Vertical Marsh Accretion [PDF]

, 2018
With sea level rise accelerating and sediment inputs to the coast declining worldwide, there is concern that tidal wetlands will drown. To better understand this concern, sources of sediment contributing to marsh elevation gain were computed for Plum ...

Effect of Atomic Oxygen on Electric Properties of Graphene Films

Cailiao gongcheng, 2017
The resistance and the surface morphology of the graphene films were studied after atomic oxygen exposure. The graphene films can be etched away during atomic oxygen exposure, the resistance of graphene films decreases at first and then increases.

Parent‐to‐Child Information Disclosure in Pediatric Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Despite professional consensus regarding the importance of open communication with pediatric cancer patients about their disease, actual practice patterns of disclosure are understudied. Extant literature suggests a significant proportion of children are not told about their diagnosis/prognosis, which is purported to negatively ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

FEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.
