Implications of Using Scalar Forcing to Sustain Reactant Mixture Stratification in Direct Numerical Simulations of Turbulent Combustion

Computation
A recently proposed scalar forcing scheme that maintains the mixture fraction mean, root-mean-square and probability density function in the unburned gas can lead to a statistically quasi-stationary state in direct numerical simulations of turbulent ...

Atomically precise metal cluster enzymes for pathological tissue regeneration

BMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

Transfersomes with core and surface‐loaded NF‐κB p65 siRNA for enhanced transdermal transfection and effective treatment of psoriasis

BMEMat, EarlyView.
TCPL, a transfersome with Tween 80 and PEI, enables efficient transdermal siNF‐κB delivery, resolving PEI's toxicity issue. It promotes lysosomal escape and effective transfection, silences NF‐κB, modulates immunity, and inhibits angiogenesis, alleviating psoriasis. With good biocompatibility, TCPL holds strong clinical translation potential. Schematic

Filling the Pockets: The Spherical Nature of 3D Deflagration in Thermonuclear Supernovae

The Astrophysical Journal Letters
We investigate thermonuclear explosions within the delayed detonation framework. While spherical delayed detonation models generally reproduce key observational features, a fundamental inconsistency emerges in three dimensions: 3D hydrodynamic ...

A Contribution to Turbulent Combustion: Premixed Flames and Material Surfaces Une contribution à la combustion turbulente : flammes prémélangées et surfaces des matériaux

Oil & Gas Science and Technology, 2006
The behavior of premixed flames has been examined by many authors. In fact the problem of combustion which develops in a turbulent medium depends on two scalings.

Harnessing blood clot as a native scaffold for orchestrating tissue repairs and regeneration

BMEMat, EarlyView.
The blood clot, owing to its dynamic composition and unique microenvironment, holds significant yet underappreciated potential for tissue engineering. This review systematically summarizes the pathophysiology of clot formation, the key regulatory factors shaping its microenvironment, and its applications in both pre‐clinical and clinical settings ...

Caveolin‐1 enriched apoptotic bodies derived from oral hard palate orchestrate bone remodeling to treat heterotopic ossification

BMEMat, EarlyView.
Downregulated CAV1 in HO is restored via apoptotic bodies from PMSCs, which reprogram bone remodeling by delivering CAV1 to target cells, highlighting the therapeutic role of EV subtypes in heterotopic ossification. Abstract Heterotopic ossification (HO) is a pathological process characterized by ectopic bone formation in non‐osseous tissues, with an ...

The Effect of Jet-Induced Disturbances on the Flame Characteristics of Hydrogen–Air Mixtures

Fire
To mitigate explosion hazards arising from hydrogen leakage and subsequent mixing with air, the injection of inert gases can substantially diminish explosion risk. However, prevailing research has predominantly characterized inert gas dilution effects on

Conditional Moment Closure Modelling of a Lifted H2/N2 Turbulent Jet Flame Using the Presumed Mapping Function Approach

Journal of Combustion, 2015
A lifted hydrogen/nitrogen turbulent jet flame issuing into a vitiated coflow is investigated using the conditional moment closure (CMC) supplemented by the presumed mapping function (PMF) approach for the modelling of conditional mixing and velocity ...

Homologous membrane wrapped ZIF‐8 nanoparticles accelerate differentiation of neural stem cell for spinal cord injury therapy

BMEMat, EarlyView.
Homologous membrane wrapped ZIF‐8 nanoparticles were proposed to improve biocompatibility and targeting ability to neural stem cells (NSCs). ZIF‐8‐SCM NPs exhibit pH responsiveness, thereby generating an intracellular Zn2+ storm to accelerate neural differentiation through calcium and MAPK signaling pathways. Moreover, they promote function recovery in
