Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Influence of the Configurations of Fuel Injection on the Flame Transfer Function of Bluff Body-Stabilized, Non-Premixed Flames

open access: yesEnergies
Combustion instability poses a significant challenge in aerospace propulsion systems, particularly in afterburners that employ bluff-body flame stabilizers.

Role of buoyancy-driven vortices in inducing different modes of coupled behaviour in candle-flame oscillators

open access: yesAIP Advances, 2019
We investigate the coupled behaviour of two oscillatory flames produced by separate bundles of candles, referred to as candle-flame oscillators, as the distance between them is varied.

Electric Field-Induced Variations of Combustion Dynamics

open access: yesChemical Engineering Transactions, 2014
An experimental study of the electric field effect on combustion dynamics at thermo-chemical conversion of biomass pellets was carried out with the aim to determine the DC field effect on the processes of biomass gasification, combustion of volatiles ...

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.

Combustion Dynamics of Swirling Flame at Thermochemical Conversion of Biomass

open access: yesChemical Engineering Transactions, 2015
Development of the swirling flame dynamics at thermo chemical conversion of biomass (wood pellets) has been investigated experimentally at a low swirl number of the swirling flame flow (S < 0.6), different rates of biomass thermal decomposition and ...

Measurement of turbulent flame speed of natural gas/air mixtures at elevated pressure [PDF]

open access: yes, 2010
Turbulent flame speeds were measured over a range of pressures to 0.8 MPa using a jet flow apparatus fired with a synthetic mixture representing a mid-European natural gas. The equivalence ratio empty set was 0.9.

Decoupling Li+ Transport in Self‐Healing Polymer Dual‐Salt Electrolytes for Room Temperature Lithium Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A self‐healable polymer matrix, crosslinked via dynamic imine bonds, is synergistically coupled with a LiPF6–LiDFOB dual‐salt system to decouple Li+ from the polymer matrix, enabling fast Li+ transport. This strategy offers an effective pathway toward high‐performance, next‐generation gel‐polymer‐based Li‐metal batteries.

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.

Unified Pressure and Field Response Across Distinct Charge‐Order Regimes in Ti‐Doped CsV3Sb5

open access: yesAdvanced Functional Materials, EarlyView.
We microscopically investigate the interplay between charge order and superconductivity in a kagome superconductor across regimes of long‐ and short‐range charge order. Hydrostatic‐pressure and magnetic‐field μSR$\mu{\rm SR}$ measurements reveal remarkably similar superconducting and normal‐state time‐reversal‐symmetry‐breaking responses in both ...
