Real-time monitoring of proton exchange membrane fuel cell stack failure [PDF]

, 2016
Uneven pressure drops in a 75-cell 9.5-kWe proton exchange membrane fuel cell stack with a U-shaped flow configuration have been shown to cause localised flooding.

Electroporation of cell membranes [PDF]

Biophysical Journal, 1989
Electric pulses of intensity in kilovolts per centimeter and of duration in microseconds to milliseconds cause a temporary loss of the semipermeability of cell membranes, thus leading to ion leakage, escape of metabolites, and increased uptake by cells of drugs, molecular probes, and DNA.

Rab35 GTPase couples cell division with initiation of epithelial apico-basal polarity and lumen opening

Nature Communications, 2016
Establishment and maintenance of apico-basal polarity in epithelial organs needs to be tightly coupled with cell division. Here the authors show that the Rab35 GTPase tethers intracellular vesicles containing key apical determinants at the cleavage site,

The microbiologist’s guide to membrane potential dynamics [PDF]

, 2020
All cellular membranes have the functionality of generating and maintaining the gradients of electrical and electrochemical potentials. Such potentials were generally thought to be an essential but homeostatic contributor to complex bacterial behaviors ...

In vitro fusion of single synaptic and dense core vesicles reproduces key physiological properties

Nature Communications, 2019
Regulated exocytosis of neuronal synaptic vesicles is substantially faster than that of endocrine dense core vesicles despite similar molecular machineries.

A model of membrane contraction predicting initiation and completion of bacterial cell division [PDF]

, 2013
Bacterial cell division involves a complex and dynamic sequence of events whereby polymers of the protein FtsZ assemble at the division plane and rearrange to achieve the goal of contracting the cell membrane at the site of cell division, thus dividing ...

Mechanics and regulation of cytokinetic abscission

Frontiers in Cell and Developmental Biology, 2022
Cytokinetic abscission leads to the physical cut of the intercellular bridge (ICB) connecting the daughter cells and concludes cell division. In different animal cells, it is well established that the ESCRT-III machinery is responsible for the ...
