The reproducibility of thermal conductivity measurements on fused silica glass by various investigators using different techniques suggests its suitability as a standard for such measurements. Our laboratory measurements with the needle probe technique on chip samples of silica glass saturated with water gave a value of 3.287 ± 0.154 (S.D.) mcal/cm s °C (n = 21) at 25 °C, which is within about 1% of the previously determined values and the value given by the manufacturer for this material. The good agreement indicates that the flat-plate steady-state and needle probe transient methods give the same value for this material, and that the water-saturated chip technique is an accurate method to measure thermal conductivity of isotropic samples.

A common garden experiment with Porphyra umbilicalis (Rhodophyta) evaluates methods to study spatial differences in the macroalgal microbiome Quigley, Charlotte T. C.; Morrison, Hilary G.; Mendonça, Inara Regina; Brawley, Susan H. (2018-07)Macroalgal microbiomes are receiving deserved study, but there is little information about microbial spatial diversity across the thallus. Reliance on field material makes it difficult to discern whether recovered microbiomes ...
