Numerical simulations of impact crater formation with dilatancy

, 2014
Impact‐induced fracturing creates porosity that is responsible for many aspects of the geophysical signature of an impact crater. This paper describes a simple model of dilatancy—the creation of porosity in a shearing geological material—and its ...

Are the detection and dimensions of peri‐implant buccal bone defects influenced by different implant materials and their location? An experimental cone‐beam computed tomography study

Journal of Periodontology, EarlyView.
Abstract Background The aim of this study is to evaluate the impact of different implant materials and arrangements within the field of view (FOV) and exomass on the diagnostic accuracy and image quality of cone‐beam computed tomography (CBCT) for the detection of peri‐implant buccal bone defects of various sizes. Methods A total of 120 CBCT scans with

Thermal Evolution of the Impact‐Induced Cryomagma Chamber Beneath Occator Crater on Ceres

Geophysical Research Letters, 2019
The faculae in Occator Crater on dwarf planet Ceres are an accumulation of salts that have been interpreted as cryovolcanic products. Current age estimates from crater counting suggest a maximum 18‐Ma difference between the crater forming impact and the ...

Exploring Electrical Resistivity Tomography (ERT) to Detect Soil Pipes: Theoretical Modeling and Field Experiments

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion research remains critical for sustainable development as it impacts soil health through different erosive processes. Recent studies on soil piping highlight advancements in detecting surface features (using UAV); however, detecting underground pipes still remains challenging.

Mechanisms of Laser Ablation in Liquids and Their Impact on the Efficiency of Nanoparticle Generation

Laser &Photonics Reviews, EarlyView.
Laser ablation in liquid enables nanoparticle synthesis from diverse materials but remains less energy‐efficient than ablation in air. This study quantifies the absorption‐corrected ablation efficiency and experimentally confirms redeposition as the key loss mechanism using pump‐probe microscopy.
