Sedimentary processes of the Bagnold Dunes: Implications for the eolian rock record of Mars

Journal of Geophysical Research - Planets, 2017
The Mars Science Laboratory rover Curiosity visited two active wind‐blown sand dunes within Gale crater, Mars, which provided the first ground‐based opportunity to compare Martian and terrestrial eolian dune sedimentary processes and study a modern ...

A Growth Model for Porous Sedimentary Rocks [PDF]

, 1997
A growth model for porous sedimentary rocks is proposed, using a simple computer simulation algorithm. We generate the structure by ballistic deposition of particles with a bimodal size distribution. Porosity and specific surface area are calculated varying the proportion of small and larger particles.

Super‐Tough Silk: The Potential of Knots in Evolved Spiders

Advanced Functional Materials, EarlyView.
The toughness of spider silk can be further significantly enhanced if spiders evolved the –currently absent/undiscovered– ability to tie knots in their silk. The results on 393 spiders suggest toughness increments by one or two orders of magnitude and thus a new perspective on how knotting can serve as a key innovation in spider evolution and in ...

A review of helochelydrid shell material from late Albian to early Cenomanian greensands of Southern England, United Kingdom

The Anatomical Record, EarlyView., 2022
Abstract A number of helochelydrid turtle shell remains were recovered over the course of the 19th century from mid‐Cretaceous sediments throughout Southern England, including the poorly figured and described types of Trachydermochelys phlyctaenus from the Cambridge Greensand of Cambridgeshire, Plastremys lata from the Upper Greensand of the Isle of ...

Biointerfacing with AgBiS2 Quantum Dots for Pseudocapacitive Photostimulation

Advanced Functional Materials, EarlyView.
It is demonstrated that AgBiS2 quantum dots exhibit unique photoinduced pseudocapacitive charge transfer properties, enabling efficient light‐to‐electrical energy conversion. These quantum dots facilitate enhanced light absorption and transduction when integrated with ZnO nanowires, which serve as an effective charge transport medium.

Description and Dynamic Analyses of the 1935 Luchedu Rock Avalanche in Sichuan, China

Geofluids, 2022
The Luchedu rock avalanche (LRA) that occurred in 1935 at the junction of Sichuan and Yunnan in Southwest China is a disaster chain of the rock slide, debris avalanche, and river blocking induced by heavy rainfall.

Nanozyme‐Shelled Microcapsules for Targeting Biofilm Infections in Confined Spaces

Advanced Healthcare Materials, EarlyView.
This study introduces a nanozyme‐microrobotic platform designed to combat bacterial infections within complex, branched confinements. Utilizing magnetic microcapsules shelled with enzyme‐mimicking nanoparticles, the microrobots achieve precise navigation, deliver targeted catalytic action at the infection site, and are fully retrievable.
