Non-woven flax fibre reinforced acrylic based polyester composites: The effect of sodium silicate on mechanical, flammability and acoustic properties

open access: yeseXPRESS Polymer Letters, 2019
Non-woven flax fibre reinforced acrylic-based polyester (NFA) composites were prepared using an impregnation process. A mixture of acrylic-based polyester (Acrodur®) with varying sodium silicate (SS) loadings was applied to impregnate the non-woven flax ...

The ozone flame [PDF]

open access: yes, 1985
The Ozone flame structure is analyzed from the point of view of asymptotic methods, using the fact that the ratios of the characteristic times associated with the different reactions, which change with the flame temperature and therefore with the initial

Managing Charge Transport and Exciton Generation for Highly Efficient, Bright, and Stable Near‐Infrared Organic Radical Light‐Emitting Diodes

open access: yesAdvanced Functional Materials, EarlyView.
High‐performing near‐infrared (NIR) organic light‐emitting diodes are demonstrated using an efficient and stable 800 nm‐emissive organic radical and a thermally activated delayed fluorescence (TADF) host. TADF‐assisted exciton generation combined with improved charge transport enables high external quantum efficiency (>8%), high radiance (>70,000 mW sr−

SIMULACIÓN BIDIMENSIONAL DE UN SISTEMA DE COMBUSTIÓN INESTABLE TWO-DIMENSIONAL SIMULATION OF AN UNSTABLE COMBUSTION SYSTEM

open access: yesIngeniare: Revista Chilena de Ingeniería, 2010
La inestabilidad en la combustión es una condición indeseada en algunos sistemas de combustión como en turbinas de gas por ejemplo. Se refiere a la presencia autogenerada de oscilaciones en la presión que pueden afectar a la cámara de combustión y de ...

Path‐Decoupled Cation‐Eutaxy III–V van der Waals Memristive Semiconductors for Mitigating the Neuromorphic Accuracy‐Energy Trade‐off

open access: yesAdvanced Materials, EarlyView.
Path‐decoupled III–V van der Waals memtransistors spatially separate ionic and electronic transport to overcome the conventional trade‐off between accuracy and energy in neuromorphic hardware. Mobile K+ ions in the vdW gaps set a wide conductance window, Gmax/Gmin, while gate‐tunable hole conduction lowers programming energy, enabling reliable ...

Stability of a spherical flame ball in a porous medium [PDF]

open access: yes, 2000
Gaseous flame balls and their stability to symmetric disturbances are studied numerically and asymptotically, for large activation temperature, within a porous medium that serves only to exchange heat with the gas.
