An Exploratory Study on Graphene‐Based Hybrid Epoxy Coatings for Corrosion Resistance and Self‐Healing

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Corrosion of metallic process equipment in chemical, marine, and offshore industries leads to significant maintenance costs and safety concerns. Conventional epoxy coatings, though widely applied, often deteriorate under harsh conditions due to microcracking, moisture ingress and lack of self‐healing capability.

Potassium Migration of Chestnut Shell Ashes Under Oxidizing Atmosphere and Its Modification Mechanism by Additives

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Biomass energy plays a critical role in alleviating environmental pressures. However, its relatively high content of alkali metals (especially for potassium) would cause ash‐related issues during combustion. To mitigate these issues, the potassium migration behaviors during chestnut shell (CS) conversion and the modification mechanisms of ...

ANALYTICAL CHARACTERIZATION OF PRECIPITATIONS

open access: yesScientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2011
The properties of precipitation are mainly determined by solid, liquid and gaseous substances that exist in suspended or dissolved form. These substances come from many complex interactions between the atmosphere – hydrosphere – lithosphere – biota.

Gleaning the Rocky Shore? 2500 Years of Coastal Resource Use at Red Bluff 1, GunaiKurnai Country, SE Australia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Shell middens in Gippsland along the eastern half of Victoria's coastline have usually been characterised as small, short‐duration camp sites with relatively low shell densities and low taxonomic diversity. Here we present new excavation results from a dense, high‐diversity site at Red Bluff near the eastern end of GunaiKurnai Country, a ...
