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.

Ultrafast Transitions in X‐Ray Irradiated Solids

Contributions to Plasma Physics, EarlyView.
ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Stabilization Strategies for Carbon Based Perovskite Solar Cells Under Light, Heat, and Humidity

EcoEnergy, EarlyView.
Carbon‐based MA1−x(AVA)xPbI3/CsPbBr3 QD heterostructures fabricated under ambient conditions exhibit < 5% loss under ISOS‐D‐3 and reversible photo‐induced degradation, revealing the dual role of QDs in defect passivation and dynamic interfacial stabilization.

Exploiting Biocatalysis for the Scalable Synthesis of Enantiopure γ‐Hydroxynitrile Building Blocks

European Journal of Organic Chemistry, EarlyView.
Screening a panel of (S)‐and (R)‐selective alcohol dehydrogenases identified several biocatalysts for stereoselectively reducing γ‐ketonitriles into γ‐hydroxynitriles. These processes were optimized, delivering the targets in yields up to 88% with e.e.’s up to 99%. Scalability of the methodology was achieved to produce gram quantities of product, which

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile

Fire and Materials, EarlyView.
ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications

Journal of the Chinese Chemical Society, EarlyView.
This article summarizes recent biochemical characterizations of a new enzyme family named by the authors as binuclear copper‐dependent oxidative enzymes (BiNCOs). Found in fungal natural product biosynthesis, BiNCOs catalyze diverse CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...

Asymptomatic Giant Right Ventricular Myxoma in an Adolescent: A Rare Case Report With Favorable Surgical Outcome

Journal of Clinical Ultrasound, EarlyView.
We report a 13‐year‐old female with a giant right ventricular myxoma extending to the pulmonary trunk. The tumor was diagnosed by multimodal imaging and completely resected, with favorable short‐term outcomes. ABSTRACT Right ventricular (RV) myxomas account for < 5% of cardiac myxomas and are often asymptomatic, easily overlooked.
