Scalable substrate development for aqueous sample preparation for atom probe tomography
Journal of Microscopy, EarlyView., 2023 Abstract Reliable and consistent preparation of atom probe tomography (APT) specimens from aqueous and hydrated biological specimens remains a significant challenge. One particularly difficult process step is the use of a focused ion beam (FIB) instrument for preparing the required needle‐shaped specimen, typically involving a ‘lift‐out’ procedure of a

Joint IODP/ICDP Scientific Drilling of the Chicxulub Impact Crater [PDF]
Scientific Drilling, 2007 The Chicxulub impact crater in Mexico (Fig. 1) is unique in the terrestrial impact record. Its association with the Cretaceous–Paleocene (K-P) mass extinction has generated great interest, but the precise environmental effects and associated extinction ...

Search for Impact Craters in Iran: Citizen Science as a Useful Method [PDF]
arXiv, 2013 To recognition probable impact craters in Iran, we use Google Earth data in the first step. Some probable structures identified and studies suggest non-impact origin for them. Studies on other craters in Iran are in progress.

The origin of the cratering asymmetry on Triton [PDF]
, 2019 The source of impactors capable of producing the cratering asymmetry on Triton is open to debate. While hyperbolic comets are the likely source of impactors, the theoretically predicted crater distribution due to impacts from comets is incompatible with the observed crater distribution on Triton.

Organic geochemistry of the crater-fill sediments from Boltysh impact crater, Ukraine [PDF]
, 2009 The Boltysh impact crater, is a complex structure formed on the basement rocks of the Ukrainian shield which has been dated at 65.17±0.64 Ma [1]. The Boltysh crater has been know for several decades and was originally drilled in the 1960s-1980s in a ...

A “Cool” Route to Battery Electrode Material Recovery
Advanced Energy Materials, EarlyView.Ice‐stripping, a novel sub‐zero electrode delamination technique, enables >90% recovery of the electrode materials from manufacturing scrap and end‐of‐life batteries. Water is sprayed upon a porous electrode and quickly freezes when placed on a cold surface. The foil is peeled away, leaving behind the black mass with the morphology retained.

Explosion cratering in 3D granular media [PDF]
arXiv, 2019 Sudden release of energy in explosion creates craters in granular media. In comparison with well-studied impact cratering in granular media, our understanding of explosion cratering is still primitive. Here, we study low-energy lab-scale explosion cratering in 3D granular media using controlled pulses of pressurized air.

Using Gamma Functions in the Mathematical Formulation of the Impact Crater Size-Age Frequency Distribution on Earth and Mars [PDF]
arXiv, 2023 A review of a mathematical formulation that describes the number of impact craters as function of diameter and time of formation is presented, where the use of Gamma functions is emphasized. The application of this formalism for the description of the impact crater data of Planets Earth and Mars is also discussed.
