On the Hydrodynamic Interplay Between a Young Nuclear Starburst and a Central Super Massive Black Hole

, 2010
We present 1D numerical simulations, which consider the effects of radiative cooling and gravity on the hydrodynamics of the matter reinserted by stellar winds and supernovae within young nuclear starbursts with a central supermassive black hole (SMBH ...

Improving Interlayer Interactions in Proton Exchange Membrane Fuel Cell through Carbon Nanotube‐Based Catalyst Design

Advanced Science, EarlyView.
This review highlights how carbon nanotube (CNT)–based catalyst designs enhance proton exchange membrane fuel cell (PEMFC) performance by improving interlayer interactions. Vertically aligned CNTs facilitate water management, mass transfer, and electron conduction while promoting effective active sites and reducing interfacial resistance.

Tailored Stitching and Vertical Stacking for High‐Voltage Multifunctional Structural Batteries with Enhanced Electrochemical–Mechanical Coupling

Advanced Science, EarlyView.
A stitched, vertically stacked CFRP structural battery uses Kevlar interlaminar threads and selective PP/Elium® thermoplastics to maintain tight electrode spacing and robust electrolyte wetting. The architecture sustains electrochemical performance under bending and delivers higher pack voltage via through‐thickness series connections without ...

Entropy generation in MHD mixed convection stagnation-point flow in the presence of joule and frictional heating

Case Studies in Thermal Engineering, 2018
This article looks at the second law analysis of MHD boundary layer stagnation-point flow past over linearly stretched sheet. The thermal boundary condition is supposed to be non-isothermal and the effects of friction and Joule heating have been analysed.

Influence of thermal boundary conditions on heat transfer from a cylinder in cross flow [PDF]

Local heat transfer data over the leading surface of a cylinder in crossflow were obtained for a Reynolds number range of 50,000. The cylinder was operated at both uniform-wall-temperature and uniform-heat-flux thermal ance of 80 deg from the front ...

Superwettable‐Membrane‐Assisted Extraction and Separation as a General Method for Removal of Organic Pollutants From Water

Advanced Science, EarlyView.
An integrated liquid‐liquid extraction and in situ superwettable membrane separation system is developed for efficient removal of organic pollutants from wastewater. After being treated with this novel technology, the residual organic pollutants are < 1.5 ppm with a removal efficiency > 95.5% and a TOC < 40 ppm, demonstrating a scalable and sustainable

The pressure confined wind of the massive and compact superstar cluster M82-A1

, 2007
The observed parameters of the young superstar cluster M82-A1 and its associated compact HII region are here shown to indicate a low heating efficiency or immediate loss, through radiative cooling, of a large fraction of the energy inserted by stellar ...

Trifunctional DOPO‐Engineered Polypropylene Separator With Li⁺‐Concentrating Interfaces for High‐Safety Lithium‐Ion Batteries Under Extreme Conditions

Advanced Science, EarlyView.
A DOPO‐based cross‐linked polymer creates a multifunctional separator for lithium‐ion batteries. It concurrently addresses safety (flame retardancy, thermal stability) and performance (enhanced Li+ transport, capacity retention), pioneering a novel approach to high‐performance battery design. Abstract This study develops a cross‐linked polymer modified
