Recent Advances in Pickering Emulsion Templated Phase Change Material Microcapsules: Design, Fabrication, and Multifunctional Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fabrication process of phase change microcapsules using a Pickering emulsion template method and their subsequent applications. The increasing demand for efficient thermal energy storage systems has driven the development of phase change material microcapsules (PCMMs), which provide high energy‐storage density, reversible phase change, and reduced ...

Pneumothorax Ex Vacuo. [PDF]

J Gen Fam Med
An 84‐year‐old woman with pleural effusion developed anterior chest pain during thoracentesis, and post‐procedural chest radiography revealed hydropneumothorax, initially suggesting iatrogenic pneumothorax. However, comparison of pre‐ and post‐procedure imaging showed ipsilateral hemithoracic volume loss with tracheal deviation toward the procedure ...

Forced Draught Impact on Externally Venting Flames: An Experimental and Numerical Investigation

Fire and Materials, EarlyView.
ABSTRACT Wind can significantly influence fire development and spread in urban and forest environments causing fatal consequences for the public, the first responders, and the environment. Wind‐driven fires can have a significant impact on structural fires as wind can increase the fire's intensity, development, and flame spread.

Eliminating air entrainment in complex siphon drainage systems: a physical modelling approach

Discover Applied Sciences
The generation of persistent foam in the cooling water discharge of coastal power plants poses significant environmental and operational challenges. This phenomenon is fundamentally driven by a "hydro-chemical coupling" mechanism, where hydraulic air ...

Experimental and Numerical Investigation of Cedar Façade Flame Spread With Respect to Sidewall

Fire and Materials, EarlyView.
ABSTRACT In response to growing energy conservation and carbon neutrality efforts, façade systems incorporating wooden materials have attracted increasing attention, which in turn raises concerns about their combustibility. This study presents a combined experimental and numerical investigation of flame spread along cedar façades.

Correlation of the entrainment factor with frother types and their mixtures in the column flotation

Cumhuriyet Science Journal, 2019
In flotation, entrainment is a mechanical mass transfer process and itis based on the changes depending on the establishment of linear relationshipbetween water and solid recovery. The present paper presents results obtainedin investigating the effect of

Stepped spillway flows and air entrainment [PDF]

Canadian Journal of Civil Engineering, 1993
Stepped spillways have become a popular method for handling flood releases. The steps significantly increase the rate of energy dissipation taking place on the spillway face and reduce the size of the required downstream energy dissipation basin. The compatibility of stepped spillways with roller compacted concrete and gabion construction techniques ...

An Experimental Investigation on the Impact of Burner Height and Location on the Characteristics of Externally Venting Flames

Fire and Materials, EarlyView.
ABSTRACT Fire sources in actual compartment fires exhibit a predominantly uneven spatial distribution. In this context, the impact of the height and location of the fire source, as well as the heat release rate (HRR) of the fire, on the thermal characteristics of Externally Venting Flames (EVF) is experimentally investigated.

Study of air entrainment and aeration devices [PDF]

Journal of Hydraulic Research, 1989
Cavitation erosion damage to spillway surfaces may be prevented with the use of aeration devices (aerators) introducing air in the layers close to the channel bottom in order to reduce cavitation damage. The performance of a spillway aerator are studied on steep spillway model with high velocities (from 4 m/s up to 15 m/s) and new air concentration and

Deglaciation of the Burren glacio‐karst, western Ireland, during Termination 1: Implications for North Atlantic climate and karstification

Journal of Quaternary Science, EarlyView.
Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...
