7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.

Investigation of the Phase‐Separation Point During CO2 Absorption in the DETA–Sulfolane–Water System

Carbon and Hydrogen, EarlyView.
Optical scattering diagnostics combined with generalized solubility product modeling enables quantitative prediction of phase separation in DETA–sulfolane–water biphasic CO2 absorbents. ABSTRACT The phase‐separation behavior of liquid–liquid biphasic amine absorbents is typically identified using bubbling reactors, where visual observation is employed ...

Combustion characteristics of methanol with turbulent jet ignition in a constant volume combustion chamber

Thermal Science
Methanol is a renewable and sustainable energy source with potential to overcome energy scarcity, global warming, and environmental pollution caused by the overdependence on fossil energy. However, its application in engines faces challenges, particularly the cold start issues.

Numerical Simulation of a Premixed Dual-Fuel Combustion in a Constant Volume Combustion Chamber

, 2021
The dual-fuel (DF) combustion concept is one of the promising strategies for modern automotive and marine engines to achieve lower emission levels. A premixed DF engine operates by having a pilot diesel injection to ignite the lean premixed natural gas in the engine.

The Effect of Working Fluids on Premixed Hydrogen Combustion in a Constant Volume Combustion Chamber

, 2019
Premixed combustion of hydrogen was investigated with the purpose of examining the effect of the full or partial substitution of argon for nitrogen in air on laminar burning velocity. Theoretically, this partial replacement decreases the NOx emissions and increases the thermal efficiency of internal combustion engines due to the high specific heat ...

A New Protocol for Measuring Gluten Index: Assessing Gluten Quality Independent of Protein Quantity

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives When assessing wheat gluten quality, traditional dough rheological tests often confound protein quality with protein quantity, making it difficult to distinguish the contribution of each factor. This study presents a modified gluten index (GI) protocol designed to evaluate wheat gluten quality independent of protein ...

Alloying Cu, Fe, and Co in Ni/YSZ Electrodes for High‐Temperature CO2 Electrolysis: Impact on TPB Density, Activity, and Carbon Deposition Resistance

Carbon Energy, EarlyView.
Systematic alloying of Ni with Cu, Fe, and Co in Ni/YSZ electrodes modifies active site density up to 43%, decreases activation energies by up to 44%, and reduces carbon deposition fourfold. Cu–Ni alloy is among the most promising alloy catalysts for electrochemical CO2 reduction in SOECs.
