The Filament Extension Atomization Process for Powder Production of Elastic Fluids

Chemie Ingenieur Technik, EarlyView.
Filament extension atomization is a promising technique for spraying a wide range of materials, enabling narrow droplet size distributions. This study examines the behavior of various fluids and suspensions to define application limits and identify optimal operating conditions.

Coupling governs entrainment range of circadian clocks

Molecular Systems Biology, 2010
Circadian clocks are endogenous oscillators driving daily rhythms in physiology and behavior. Synchronization of these timers to environmental light–dark cycles (‘entrainment’) is crucial for an organism's fitness.

From Potentiostatic to Galvanostatic Control in Pulsed Electrochemical CO2 Reduction to Ethylene

Chemie Ingenieur Technik, EarlyView.
A two‐gap flow cell with three‐electrode configuration bridges the gap between H‐cells and industrial zero‐gap electrolyzers. Using ethylene‐selective CO2 reduction on copper as a model reaction, galvanostatic operation shows greater stability than potentiostatic control, whereas charge‐controlled pulsed protocols enable C2H4 selectivity under ...

Occurrence of severe slugging in oil production lines and mitigation methods: A numerical simulation approach using ALFAsim®

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Severe slugging represents a major challenge in offshore production systems, potentially compromising operational stability and the integrity of installations. Although established simulators such as OLGA® are widely used for its analysis, there is a gap in the literature regarding the application of the one‐dimensional simulator ALFAsim® for ...

Energy evolution‐based damage quantification and failure prediction of fault zone tunnel lining concrete: A novel acoustic emission–strain energy coupling approach

Deep Underground Science and Engineering, EarlyView.
This study investigates the damage evolution and failure mechanisms of tunnel lining concrete in active fault zones through uniaxial compression tests integrated with acoustic emission (AE) monitoring. A strong linear correlation is identified between the AE cumulative absolute energy and the total strain energy, providing a reliable energy‐based ...

An accessible microfluidic perfusion platform for time‐restricted control of zebrafish embryonic patterning

Developmental Dynamics, EarlyView.
Abstract Understanding the dynamic nature of developmental networks requires live imaging techniques capable of capturing real‐time developmental processes in wild‐type and mutant embryos as they are exposed to pharmacological perturbations. A peculiar developmental patterning process in early vertebrate embryos is the sequential segmentation of ...

From bodyweight to biomarkers: Season‐associated metabolic, endocrine and haematological shifts in breeding stallions

Equine Veterinary Journal, EarlyView.
Abstract Background Breeding stallions are subjected to sustained seasonal metabolic, endocrine, and immune demands requiring systemic energy engagement. Prospective longitudinal data in the same individuals are limited. Objectives To screen adaptive responses of breeding stallions of clinical relevance through longitudinal characterisation of temporal

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.

Effect of momentum flow ratio on entrainment of a confined coaxial jet in a co-flow

Engineering Applications of Computational Fluid Mechanics
Iron ore pellet production processes produce large amounts of CO2 emissions when burning fossil fuels. One example is the grate-kiln process, where normally a coal flame is used to indurate pellets. To mitigate the emissions, coal used in rotary kilns can be replaced with for example hydrogen.
