Rapid Manipulation in Irradiance Induces Oxidative Free-Radical Release in a Fast-Ice Algal Community (McMurdo Sound, Antarctica)

open access: yesFrontiers in Plant Science, 2020
Sea ice supports a unique assemblage of microorganisms that underpin Antarctic coastal food-webs, but reduced ice thickness coupled with increased snow cover will modify energy flow and could lead to photodamage in ice-associated microalgae.

And then came the microelectrode [PDF]

open access: yesCardiovascular Research, 2002
It is difficult to fully appreciate the contributions made by the microelectrode to the understanding of cardiac electrophysiology without some idea of the prior state of the field. What was known about cardiac electrophysiology had been derived largely from studies of the electrocardiogram and cardiac electrogram and by the application of stimuli ...

On the Formation of Glass Microelectrodes

open access: yesSIAM Journal on Applied Mathematics, 2007
Glass microelectrodes are used widely in experimental studies of the electrophysiology of biological cells and their membranes. However, the pulling of these electrodes remains an art, based on trial and error. Following Huang et al. [SIAM J. Appl. Math., 63 (2003), pp.
