The influence of temperature on the development of shock deformation effects in quartz single-crystal targets has been investigated in this parameter study. Quartz targets were pre-cooled to 77 K and shocked parallel to their ( 101 ; − 0 ) orientat

In recent years, apparently shock-induced and, thus, impact-characteristic microdeformations, in the form of planar microdeformation features and so-called strawberry (granular) texture, have been observed in zircons in rocks from confirmed impact st

Laminated targets consisting of steel/ceramic/steel layers have a high level of protection against shaped charge penetration. However, using very thick ceramic layers the targets loose their protective capability. This implies that different physical

Impact-induced ejections of rocks from planetary surfaces are frequent events in the early history of the terrestrial planets and have been considered as a possible first step in the potential interplanetary transfer of microorganisms. Spores of Baci

Shock experiments with the reflection method were carried out at room (Troom)- and pre-shock (Tpre) temperatures of 300 and 600 °C at pressures ranging from 30 to 75 GPa to investigate the structural deformation on fluorophlogopite (KMg3(Si3AlO10)F2

For the first time, shock-wave induced intragranular glass lamellae similar to the so-called “diaplectic glasses” reported from shock-loaded framework silicates such as SiO2-polymorphs and feldspars have been observed by TEM for mullite 2Al2O3:1S

The 8.8-kb amplifiable unit of DNA of Streptomyces achromogenes subsp. rubradiris, AUD-Sar 1, which carries 0.8-kb terminal direct repeats and a spectinomycin resistance determinant, can mediate high-level amplification of an AUD-Sar 1-derived 8.0-kb

During the last 10 years shaped charges with spherical liners have aroused great interest in research and development because their application in special munition results in an increase in performance. The present report presents measured characteri

Summary Feeding experiments with tryptophan tritiated stereospecifically at C-3 indicate that the C methylation at the methylene group of indolepyruvate, an early step in the biosynthesis of the antibiotic indolmycin, proceeds stereospecifically with
