Enzymatic synthesis of acylglycerides from agroindustrial residues: process design and simplified techno‐economic assessment

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study developed an enzymatic process to add value to palm oil fatty acid distillate (PFAD) and glycerol, resulting in the production of monoacylglycerides (MAG) and diacylglycerides (DAG). The biocatalyst loading (Novozym 435) and molar ratio of reagents were evaluated to obtain a suitable reaction condition in terms of space–time yield ...

An SMLD joint PDF model for turbulent non-premixed combustion using the flamelet progress-variable approach

, 2015
This paper provides an improved flamelet/progress variable (FPV) model for the simulation of turbulent combustion, employing the statistically most likely distribution (SMLD) approach for the joint probability density function (PDF) of the mixture ...

Sustainability Orientation and Sustainable Innovation: Can Organisational Resilience Clarify the Missing Link?

Business Strategy and the Environment, EarlyView.
ABSTRACT Although firms that integrate a sustainability orientation (SO) may experience a significant improvement in their resource efficiency, many, particularly small‐ and medium‐sized enterprises (SMEs), still struggle with the complexities of incorporating sustainability into their business models.

From Two‐Electron to Four‐Electron System: Electrolyte Regulation for Advanced Aqueous Zn–I2 Batteries

Carbon Energy, EarlyView.
This review systematically summarizes recent progress in electrolyte‐regulated aqueous Zn–I2 batteries (AZIBs). It outlines the fundamentals of AZIBs along with their main challenges, and then analyzes electrolyte‐engineering strategies that improve both two‐ and four‐electron reactions.

Multifunctional Design of Solid Polymer Electrolytes: Paving the Way for High‐Performance All‐Solid‐State Batteries

Carbon Energy, EarlyView.
This review provides a comprehensive and systematic overview of the multifunctional design strategies for solid polymer electrolytes (SPEs), a pivotal component for enabling high‐performance all‐solid‐state batteries (ASSBs). It begins with a detailed classification of SPE systems and elaborates on their respective molecular design principles. The work

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

Amplification of turbulence level by a flame and turbulent flame velocity

Combustion and Flame, 1972
In turbulent combustion, the existence of turbulence increnses the flame velocity markedly, while the flame augments the intensity of turbulence. A consideration of this interaction between a flame and the aerodynamics (turbulence) has led to a set of equations from which turbulent flame velocities can be calculated with reasonable accuracy over a wide

Turbulence, combustion, pollutant, and stability characterization of a premixed, step combustor [PDF]

A two dimensional combustion tunnel was constructed to study a lean premixed turbulent propane/air flame stablized behind a rearward facing step. Studied were: (1) the existence and importance of large coherent structures in turbulent reacting and ...
