Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

The Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Laser oscillation in epitaxial GaAs waveguides with corrugation feedback [PDF]

, 1973
Laser action was observed in GaAs epitaxial films using corrugation feedback. The output wavelength was found to depend on the corrugation period.

Digital and Gender Attributes of IC in Sustainability Reporting of Italian Firms

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Italian listed enterprises increasingly rely on intellectual capital (IC) to enhance competitiveness and sustainability performance. As IC, comprising human, structural, and relational capital, is rarely recognised in financial statements due to the lack of standardised frameworks, its disclosure has gained relevance in sustainability ...

Shock wave propagation characteristics of aluminum‐containing explosive in corrugated steel‐lined tunnel

Deep Underground Science and Engineering, EarlyView.
Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

Carbon‐Negative Upcycling of Sewage Sludge into Superiorly Stable Gel Via Liquid‐Phase Utilization Strategy for Water‐Remediation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work developed a low‐temperature sludge hydrothermal coupled with gel crosslinking strategy which could upgrade the waste liquid generated from sewage sludge hydrothermal treatment into the hydrothermal‐liquid‐gel. The inventive hydrothermal‐liquid‐gel exhibited the enhanced pollutant removal capability, high synthetic stability, and superior ...

Control of Wave Reflection-Induced Rail Corrugation and Associated Rolling Noise on High-Elastic Fastener Tracks

Applied Sciences
Short-pitch rail corrugation is prevalent on metro tracks with high-elastic fasteners and is closely linked to rolling noise. Field measurements show that the in situ pass-by noise reaches its maximum in the 600 Hz–1 kHz range.

In Situ Bilayer Interphase Enables Air‐Stable Li Metal Anode for Long‐Term Li‐Air Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An in situ formed bilayer SEI—featuring an Ag/LiF‐enriched inner backbone and a CF3‐dominated hydrophobic outer shell—enables fast/uniform Li+ transport and exceptional moisture‐air stability for Li metal. Lithium metal is an attractive anode for next‐generation high‐energy batteries, but its practical use is plagued by dendrite growth and parasitic ...
