Scientific drilling of the Boltysh impact crater, Ukraine [PDF]
, 2009 Introduction: The Boltysh crater has been known for several decades and was first drilled in the 1960s as part of a study of economic oil shale deposits. Unfortunately, the cores were not curated and have been lost.

Antifouling Coatings Inspired by Biological Templates
Macromolecular Rapid Communications, EarlyView.The polymeric coatings developed using biological templates combine antifouling properties of polymers with mechanical properties of micro‐ and nano‐particles yielding contact active, foulant releasable, and stimuli responsive materials with superior antifouling performance and demonstrate several applications in the marine environment, as delivery ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT The paper investigates environmental conditions prevailing at the southern margin of the European periglacial domain in NW Hungary (Kemeneshát area) during the Late Pleistocene. Samples of sediments infilling sand wedges and their host sediments were analyzed by examining the grain‐size distributions, as well as the morphology and ...

Mass mortality and extraterrestrial impacts [PDF]
The discovery of iridium enrichment at the Cretaceous/Tertiary boundary resulted in formulation of hypothesis of a cometary or asteroid impact as the cause of the biological extinctions at this boundary. Subsequent discoveries of geochemical anomalies at

Hypersonic Jets of Detonation Products in the Hydrodynamic Collapse of Macroscopic Voids
Propellants, Explosives, Pyrotechnics, EarlyView.Using machined mm‐scale voids at the surface of PBX 9501 samples, detonation‐driven jets of product gases form. We find that there is an optimal distance from the charge surface at which the energy transfer due to this jetting is maximized using witness plate impact experiments and hydrocode simulations.
