Integral Experiments and Magnetic Resonance Imaging of Lab‐Scale Liquid Distributors
Chemie Ingenieur Technik, EarlyView.Four lab‐scale liquid distributors were evaluated based on the homogeneity of the resulting liquid distribution. The best‐performing design reduced maldistribution and wall flow compared to a single‐point liquid distribution and remained stable under varying operating conditions, including different gas and liquid loads.

Application of dynamic modelling and model‐based predictive control to enhance a cooling tower
The Canadian Journal of Chemical Engineering, EarlyView.Model predictive control (MPC) applied to improve the operation of cooling towers. Abstract Model predictive control (MPC) differs from traditional feedback control by making predictions within a time horizon, providing better control actions for the process.

Efficiency of epibenthic Renfro beam nets for sampling penaeid shrimp
Ciencias Marinas, 1994 The efficiency of a Renfro beam trawl net was tested in vegetated and nonvegetated habitats of Términos Lagoon, Mexico. The white shrimp, Penaeus setiferus (87%), predominated over the brown shrimp.

EcoEnergy, EarlyView.This study presents a novel 3‐reactor chemical looping system for CO2 capture and subsequent utilization with biomass and natural gas for producing liquid fuels. Using Ca2Fe2O5\Fe2O3 oxygen carriers, it achieves 60% CO2 capture efficiency, ∼80% syngas purity, and autothermal operation, offering a scalable, carbon‐negative route to sustainable fuels ...

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems
Energy Science &Engineering, EarlyView.This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...
