Comparison of the Coating Structure of Silicon‐Based PECVD Coatings With Varying Organic Content

open access: yesPlasma Processes and Polymers, EarlyView.
Silicon‐based PECVD coatings transition abruptly from organic SiOCH to oxidic SiOx at ~32 at% silicon, exhibiting threshold behavior in barrier performance. Chemical composition seems to dominate over porosity: SiOx coatings unexpectedly show higher porosity yet superior barrier properties, possibly due to rigid cage‐like molecular structures ...

Sonified Signals From a Compact FT‐ICR Instrument: A Feasibility Study. I—Data Mapping to an Equal‐Tempered Chromatic Scale

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

Introducing Epigenetics Into Secondary School Classrooms—An Educational Design Study

open access: yesScience Education, EarlyView.
ABSTRACT Although epigenetics represents an emerging field of biological research with a potentially large influence on society as well as conceptual implications on how genetics is understood, it is often not a part of the biology education provided at secondary schools.
