Impact Rates in the Outer Solar System

open access: yesThe Planetary Science Journal, 2023
Previous studies of cometary impacts in the outer solar system used the spatial distribution of ecliptic comets (ECs) from dynamical models that assumed ECs began on low-inclination orbits (≲5°) in the Kuiper Belt.

Multi‐Dimensional Conductive Nanocomposites for Flexible Electronics

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Multi‐dimensional conductive nanocomposites integrate 0D, 1D, and 2D nanomaterials through spatial structure regulation and interface engineering, achieving “1 + 1 > 2” synergistic effects. By leveraging 0D filling to reduce contact resistance, 1D bridging to construct continuous conductive paths, and 2D supporting to enhance mechanical stability ...

Widespread effusive volcanism on Mercury likely ended by about 3.5 Ga

open access: yesGeophysical Research Letters, 2016
Crater size–frequency analyses have shown that the largest volcanic plains deposits on Mercury were emplaced around 3.7 Ga, as determined with recent model production function chronologies for impact crater formation on that planet.

Shocked quartz in distal ejecta from the Ries impact event (Germany) found at ~ 180 km distance, near Bernhardzell, eastern Switzerland

open access: yesScientific Reports, 2021
Impact ejecta formation and emplacement is of great importance when it comes to understanding the process of impact cratering and consequences of impact events in general. Here we present a multidisciplinary investigation of a distal impact ejecta layer,

Dominant Lithium‐Ion Conduction and Desolvation Regulation Enabled by Lithiated Monodisperse Nanospheres Composite Separator for High‐Nickel Lithium Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
To match high‐nickel lithium batteries, a composite separator is designed using a sulfonation‐lithiation nanosphere coating modification strategy. The composite separator can enhance the selectivity of lithium‐ion transport, accelerate Li+‐desolvation, and capture Ni, Co, and Mn ions.

Premature rejection in science: The case of the Younger Dryas Impact Hypothesis

open access: yesScience Progress, 2022
The progress of science has sometimes been unjustifiably delayed by the premature rejection of a hypothesis for which substantial evidence existed and which later achieved consensus. Continental drift, meteorite impact cratering, and anthropogenic global

Impact cratering experiments into highly porous bodies [PDF]

open access: yes, 2011
Asteroids represent both an opportunity and a risk. Their pristine environment captures the early collision evolution of the solar system; while their inherent ground impact potential could result in the mass extinction of life.

Biomaterials for resolution of peri‐implantitis: Consensus report of Workgroup 2 of the IADR Implantology Research Group Best Evidence Consensus Symposium on Peri‐Implant Disease and Its Treatment

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Peri‐implantitis is a destructive disease affecting the tissues surrounding dental implants. Biomaterials may be applied during surgical treatment to reconstruct bony defects and support soft tissue healing. However, current evidence is unclear if these treatments increase the likelihood of peri‐implantitis resolution.

Low-gravity impact experiments: Progress toward a facility definition [PDF]

open access: yes
Innumerable efforts were made to understand the cratering process and its ramifications in terms of planetary observations, during which the role of gravity has often come into question.
