Heating in collisions of solids:possible application to impact craters [PDF]

, 2012
Due to the importance of collisions and impacts in early phases of the evolution of the planetary system, it is interesting to estimate the heating of a solid target due to an impact in it .

Reconstructing the Holocene explosive eruptive history of the Erciyes volcano (Turkey) using proximal and distal tephra records

Journal of Quaternary Science, EarlyView.
ABSTRACT Mount Erciyes, the largest active volcano of Central Anatolia (Turkey), erupted explosively during the Holocene, producing the Karagüllü, Perikartin and Dikkartin tuff rings. Even though major cities like Kayseri and its ~1 million residents sit directly on these pyroclastic deposits, the timing and magnitude of the explosive eruptions have ...

Magnetic Field Signatures of Craters on Mars

Geophysical Research Letters
Craters on Mars are a window into Mars' past and the time they were emplaced. Because the crust is heated and shocked during impact, craters can demagnetize or magnetize the crust depending on the presence or absence of a dynamo field at the time of ...

Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments

Journal of Raman Spectroscopy, EarlyView.
Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.

Automated Photothermal Control of Block Copolymer Self‑Assembly and Metal Oxide Nanostructures Sintering

Macromolecular Rapid Communications, EarlyView.
This study presents a microscope‐based photothermal platform that integrates structured laser light projection with machine‐learning‐optimized illumination. By employing neural‐network models to predict and generate thermal profiles, the platform achieves precise thermal processing of block copolymer films.

Identification of small impact craters in Chang’e-4 landing areas using a new multi-scale fusion crater detection algorithm

Earth and Planetary Physics
Impact craters are important for understanding the evolution of lunar geologic and surface erosion rates, among other functions. However, the morphological characteristics of these micro impact craters are not obvious and they are numerous, resulting in ...
