Experimental Investigation of Rising Gas Bubble Characteristics from a Vertical Tube under CCFL Condition

Science and Technology of Nuclear Installations, 2012
This paper describes an experimental study of gas/liquid countercurrent flow in a vertical circular tube. CCFL experiments were carried out with three different water levels in the upper plenum, two different tube diameters.

Bubbling Inception Temperature in Power Transformers—Part 1: Comparative Study of Kraft Paper, Thermally Upgraded Kraft Paper, and Aramid Paper With Mineral Oil

IEEE Access
The bubbling inception temperature (BIT) of insulating materials used in transformers is critical for their performance and lifespan. This study, which represents the first part of a two-part series, provides a comparative analysis of the BIT for kraft ...

Formation of Small Bubbles in an Electric Field

Separation Science and Technology, 1995
The formation of gas bubbles injected into an insulating liquid was studied under the influence of a nonuniform electric field. The electrode configuration used consisted of a charged capillary opposite a grounded ring, and gas bubbles were formed at the capillary tip.

Facile Preparation of Carbon Membranes Derived from a Fluorenyl‐Containing Polyimine for Selective Hydrogen Separation

Advanced Functional Materials, EarlyView.
A fluorenyl‐containing polyimine is introduced as a simple, scalable precursor for high‐performance carbon membranes. The precursor's intrinsic kinked structure enables defect‐free membrane formation with enhanced hydrogen permeance and excellent ideal selectivities for key industrial gas pairs (H2/N2, H2/CH4, and H2/CO2), offering a practical route ...

Model for the Formation of Helium Bubbles in Palladium

Croatica Chemica Acta, 2013
In implantation experiments or in the inner wall of the vessel of nuclear reactors, irradiation of metals with helium damages the material by forming defects. We focus on studying the formation of He bubbles by analyzing the energetics of He atoms in bulk palladium and present a simple model for bubble formation.

Spatiotemporal Drug Delivery via a Neonatal Spinal Cord ECM Hydrogel for Biomimetic Microenvironment Remodeling After Spinal Cord Injury

Advanced Functional Materials, EarlyView.
A biomimetic hydrogel derived from neonatal spinal cord ECM (DNSCM) delivers LAMB2 protein and ISP peptide to remodel the inhibitory injury microenvironment. The system sustains drug release, upregulates pro‐regenerative LAMB2, downregulates inhibitory CSPG, and promotes axonal regeneration.
