Polygonal Impact Craters on Ganymede

, 2023
Polygonal impact craters (PIC) are impact craters that have at least one straight rim segment in planform. Among all impact craters, PICs represent a small percentage. They exist on both rocky and icy planetary bodies.

Survival of Ancient Lunar Water Affected by Topographic Degradation of Old, Large Complex Craters

Geophysical Research Letters, 2022
Lunar water is redistributed by various processes. Topographic diffusion affects the transport of water and contributes to its preservation in subsurface layers.

Investigation Into the Electrochemical Performance of Micron‐ and Nanosized Tin in Diglyme and Carbonate Electrolytes in Sodium Ion Batteries

Advanced Energy Materials, EarlyView.
This study compares Sn particles of different sizes in NIBs using carbonate‐ and diglyme‐based electrolytes. Diglyme electrolytes enable stable cycling despite large volume changes, while carbonate electrolytes degrade rapidly, especially with nanoparticles.

Automatic Mapping of Small Lunar Impact Craters Using LRO‐NAC Images

Earth and Space Science, 2022
Impact craters are the most common feature on the Moon’s surface. Crater size–frequency distributions provide critical insight into the timing of geological events, surface erosion rates, and impact fluxes.

Arthroscopic Three Hybrid Anchor Construct Fixation in Skeletally Immature Patients With Tibial Eminence Fractures

Arthroscopy Techniques, EarlyView.
Abstract This article describes a surgical technique for skeletally immature patients with tibial eminence fractures of the anterior cruciate ligament (ACL) insertion. Owing to the distinct anatomical characteristics in skeletally immature patients compared with adults, we arthroscopically implanted a three hybrid anchor construct into the posterior ...

Single flap approach combined with periosteal pedicle flap as a regenerative procedure: A case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background Single flap approach (SFA) is a validated procedure for obtaining clinical attachment gain and pocket closure when applied to deep intraosseous defects. However, the presence of an interdental crater as well as the tooth location were associated with a lower rate of primary intention closure, possibly jeopardizing the outcome of the

The Effect of Antecedent Topography on Complex Crater Formation

Geophysical Research Letters
Impact craters that form on every planetary body provide a record of planetary surface evolution. On heavily cratered surfaces, new craters that form often overlap antecedent craters, but it is unknown how the presence of antecedent craters alters impact

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

ENERGY &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.

CraterIDNet: An End-to-End Fully Convolutional Neural Network for Crater Detection and Identification in Remotely Sensed Planetary Images

Remote Sensing, 2018
The detection and identification of impact craters on a planetary surface are crucially important for planetary studies and autonomous navigation. Crater detection refers to finding craters in a given image, whereas identification means to actually ...
