Global existence for a translating near-circular Hele-Shaw bubble with surface tension [PDF]

open access: yes, 2009
This paper concerns global existence for arbitrary nonzero surface tension of bubbles in a Hele-Shaw cell that translate in the presence of a pressure gradient.

Bounce in Valley: Study of the extended structures from thick-wall to thin-wall vacuum bubbles

open access: yes, 1994
The valley structure associated with quantum meta-stability is examined. It is defined by the new valley equation, which enables consistent evaluation of the imaginary-time path-integral. We study the structure of this new valley equation and solve these

Operando Temperature Sensing at the Actual Electrocatalytic Interface by Nanodiamond Quantum Sensors

open access: yesAdvanced Functional Materials, EarlyView.
By integrating a wide‐field microscope with a custom‐designed electrolyzer, nanoscale temperature changes can be recorded in situ during the electrolysis process without interfering with ongoing electrochemical reactions. This method establishes a correlation between the interface temperature and specific electrochemical reactions, making the measured ...

A Study of Water Modelling on Mechanism of Removal of Inclusions in Molten Steel by Bubble Wake

open access: yesTeshugang, 2014
The removing process of inclusions by bubble wake in steel has been studied by using water model and high-speed video recorder and the rule of inclusions removing through bubble wake and the effect of bubble size and inclusion size and concentration on ...

Hydrodynamic characteristics of the microbubble dissolution in water using an ejector-type bubble generator

open access: yesCase Studies in Chemical and Environmental Engineering
This research uses an ejector bubble generator to determine water's flow structure and dissolved oxygen. The horizontal position of ejector, modified from conventional venturi, utilizes a gradual reduction in cross-section at the water inlet and contains

The reionizing bubble size distribution around galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society
ABSTRACT Lyman-alpha (Ly α) emission from galaxies is currently our most promising probe for constraining when and how reionization began, and thus when the first galaxies formed. At z > 7, the majority of galaxies detected with Ly α are in candidate overdensities.

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement

open access: yesAdvanced Functional Materials, EarlyView.
An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...

Stoma‐Shell Nanoarchitecture for Enhanced Plasma Confinement Catalysis in Synthesis of Ethanol from CO2

open access: yesAdvanced Functional Materials, EarlyView.
High‐energy electron impact in plasma catalysis often causes excessive dissociation of active intermediates, limiting C2+ product selectivity. To address this challenge, a bio‐inspired stoma‐shell nanoarchitecture is designed to decouple electron impact from catalytic reaction zones.
