Boiling--a process that has powered industries since the steam age--is governed by bubble formation. State-of-the-art boiling surfaces often increase bubble nucleation via roughness and/or wettability modification to increase performance. However, without active in situ control of bubbles, temperature or steam generation cannot be adjusted for a given heat input. Here we report the ability to t...

The Diamond booster and storage ring are equipped with Libera Electron Beam Position Processors with turnby-turn capabilities. We describe here the turn-by-turn data acquisition system and the software used for postprocessing the beam data. The signals from the Libera boxes are acquired and controlled with EPICS and then transferred to the MATLAB environment via the MATLAB Channel Access or Lab...

A turn-by-turn vertical beam profile monitor has been developed at the Cornell Electron Storage Ring (CESR). The instrument optically images the vertical beam distribution with an array of optical fibers that transport visible synchrotron radiation to an array of photo-multiplier tubes. Each PMT signal is recorded by a turn-by-turn data acquisition system. With this instrument, we compare profi...

The presence of small vesicles composed of phospholipid and cholesterol has recently been demonstrated in super-saturated model and in dilute native human biles by several groups using differing methods. Among compositional factors shown to favor spontaneous vesicle formation and prolong the cholesterol monohydrate nucleation time in model bile systems are dilution, a raised cholesterol saturat...

In the present research, damage mechanisms during room temperature uniaxial tensile testing of two different modern high strength dual phase steels,DP780 and DP980, were studied. Detailed microstructural characterization of the strained and sectioned samples was performed by scanning electron microscopy (SEM). The results revealed that interface decohesion, especially at the triple junctions of...

TPX2 is a widely conserved microtubule-associated protein that is required for mitotic spindle formation and function. Previous studies have demonstrated that TPX2 is required for the nucleation of microtubules around chromosomes; however, the molecular mechanism by which TPX2 promotes microtubule nucleation remains a mystery. In this study, we found that TPX2 acts to suppress tubulin subunit o...
