Multi‐Objective RSM Optimization of Emission and Performance Characteristics in a Diesel Engine Fueled With BaTiO3 Nano‐Enhanced Jojoba Biodiesel

open access: yesEnergy Science &Engineering, EarlyView.
This study uses response surface methodology to optimize Jojoba biodiesel blended with BaTiO3 nanoparticles in a single‐cylinder diesel engine. Results show that ~48.95–51.31 ppm of BaTiO3 achieves balanced performance and emission, decreasing CO and NOx while increasing torque and brake thermal efficiency.

Food Security Versus Environmental Health: The Nitrogen Dilemma

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

How well do global ocean approaches constrain local fCO2?

open access: yesEnvironmental Research Letters
The ocean absorbs 29% of humanity’s annual anthropogenic carbon dioxide (CO $_2$ ) emissions, and the future of climate change is strongly dependent on how this sink evolves.

Ngarrawa (mound spring) sediments as archives of Holocene environmental change in arid central Australia: Insights from Itrax XRF scanning

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Central Australia's ngarrawa, or ‘mound springs’, are unique hydrological systems that serve as some of the only near‐permanent sources of water and continuous sediment deposition in Australia's arid interior. As such, they hold significant potential as palaeo‐climate and ‐environmental archives in a region where many aspects of past climate ...
