Characteristics of onset of boiling under downward flow condition

Nihon Kikai Gakkai ronbunshu, 2020
Understanding of the onset of boiling plays an important role in the design of boiling equipment. Therefore, many studies have been reported so far, but most of these concerned with the upward flow condition.

X-ray Imaging-Based Void Fraction Measurement in Saturated Flow Boiling Experiments with Seawater Coolant

Quantum Beam Science, 2021
Recent studies have shown that the presence of dissolved salts in water can exhibit peculiar flow boiling and two-phase flow regimes. Two-phase flow and convective flow boiling are typically characterized with the help of void fraction measurements.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Flow in fuel nozzles under cavitation and flash-boiling conditions

AIP Advances, 2022
Cavitation plays a crucial role in various fuel systems and spray applications. Due to the limitation in experimentally measuring the cavitation flow in fuel nozzles, numerical simulations can be used as an alternative in exploring the underlying physics.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
