A passive method for sampling water in the soil–plant–atmosphere continuum for stable hydrogen and oxygen isotope analyses

open access: yesRapid Communications in Mass Spectrometry, Volume 38, Issue 2, 30 January 2024.
Rationale Hydrogen and oxygen isotopes in water molecules are powerful tools to constrain the dynamics of water cycling within the soil–plant–atmosphere continuum (SPAC). However, the recovery of water from the SPAC requires logistical arrangements and implementation of different time‐ and cost‐consuming techniques in either the field or the laboratory.

Stirling pulse tube cryocooler using an active displacer [PDF]

open access: yesCryogenics, 2018
An in-line pulse tube cryocooler with an active displacer has been built and its performance has been examined in detail by experimental measurements and numerical modelling. An active displacer allows the mass flow at the cold end to be easily adjusted for optimum performance.
