Effect of Nanosilica Aggregates/Agglomerates on Functional Properties of Poly(Butylene 2,5‐Furandicarboxylate)‐Based Nanocomposites

Polymer Composites, EarlyView.
Effect of nanosilica aggregates/agglomerates on oxygen and water vapor diffusivity of PBF/SiO2 nanocomposites. ABSTRACT The nanofillers inclusions in poly(butylene 2,5‐furandicarboxylate) (PBF)/SiO2 nanocomposites were found to consist of aggregates and agglomerates of nanosilica particles.

Experimental analysis of laminar spherically expanding flames

Analyse expérimentale des flammes en expansion sphérique : quelles formulations pour la vitesse de combustion ? Bien qu'étudiée depuis plus de 100 ans, la détermination expérimentale de la vitesse de combustion reste compliquée. Dans ce travail de thèse, la configuration de flamme sphérique en expansion a été choisie.

Performance improvement of carbon fiber‐reinforced ABS composites by introducing fullerene nanoparticles

Polymer International, EarlyView.
Fullerene particles were incorporated with CF‐reinforced acrylonitrile–butadiene–styrene terpolymer (ABS) matrix at three different compositions by a melt‐compounding process. These insights are crucial for the optimization of conductive hybrid composites for various applications.

Exploding Bridgewire (EBW) Detonators: An Example of Synergistic Multiphysics

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Exploding bridgewire (EBW) detonators are highly temporally reproducible explosive devices that require the rapid discharge of a high‐voltage capacitance to operate and so are immune to most of the accidental hazards associated with traditional electric detonators.

Relationship investigation between quantitative cellular information and self-acceleration of lean hydrogen-air spherical premixed flame [PDF]

Due to the high diffusivity of hydrogen molecules, lean hydrogen-air premixed flames are more prone to cellular instability during combustion. This instability is known to often lead to self-acceleration of flame propagation, with the flame speed closely

Breaking Inversion Symmetry via Vanadium Coordination Engineering in Bismuth Vanadium Selenites

Small, EarlyView.
Vanadium coordination engineering induces symmetry breaking in bismuth selenites by transforming symmetry‐compensated VO6/VO5F units into directionally aligned VO5 polyhedra. The resulting non‐antiparallel vanadyl arrangement eliminates dipole cancellation and stabilizes a polar noncentrosymmetric framework with nonlinear optical activity.
