Thermal accommodation in nanoporous silica for vacuum insulation panels
International Journal of Thermofluids, 2020 The thermal accommodation coefficient is a measure for the quality of thermal energy exchange between gas molecules and a solid surface. It is an important parameter to describe heat flow in rarefied gases, for example, in aerospace or vacuum technology.

Overview of Diagnostic Ultrasound Safety
Journal of Ultrasound in Medicine, Volume 45, Issue 3, Page 487-496, March 2026.Ultrasound is widely regarded as a safe imaging modality; however, emerging ultrasound‐based techniques—such as shear wave elastography and contrast‐enhanced ultrasound—operate with varying acoustic output parameters that may approach or exceed traditional diagnostic limits. As these technologies are increasingly integrated into human research studies,

High Pressure Stabilizes the Elusive Hexacoordinated Carbon
ChemistryEurope, Volume 4, Issue 2, February 2026.The MCF6 species (M = Ca, Sr) is more stable than the bicomponent MF2…CF4 mixture in the solid‐state at high pressure (p > 400 GPa). The main building block is the [CF6]2− unit in which carbon is hexacoordinated. Unusually high coordination number for elements has been of great interest in chemistry.
