Bioleaching as an Eco-Friendly Nano-Factory for Sustainable Inorganic Waste Management: Current Advancements, Challenges, and Opportunities. [PDF]
The review explores the latest updates and information about the global trends and hazards of e‐waste and also discusses the bioleaching of metals and nanoparticles from various inorganic wastes. It also focuses on the mechanistic pathway of the bioleaching process and computational aspects. Inorganic waste management and metal recovery technology pose

Detrital platinum group minerals (PGM) are rare and distinctive in Pleistocene–Holocene sedimentary systems of the southern South Island, thereby enabling tracking of their long‐distance transport for ∼200 km. The first ∼100 km of transport involved Pleistocene glaciofluvial processes southwards down the Waiau River, where PGM (principally Pt–Fe and Ru–

Abstract The long‐term viability of Jatropha curcas as a biodiesel feedstock has been widely debated. Many early initiatives failed to deliver consistent economic returns despite promising environmental attributes. This study re‐evaluated J. curcas‐based systems within an integrated environmental–economic framework, focusing on their potential role in ...

The study of heavy mineral assemblages with statistical analysis resolves provenance signatures and quantifies syn‐emplacement modification of sand injection complexes. Results demonstrate transformative petrological processes, including density‐dependent hydraulic sorting and mechanical grain degradation.

Effects of different casting mould cooling rates on microstructure and properties of sand-cast Al-7.5Si-4Cu alloy [PDF]
In this work, Al-7.5Si-4Cu alloy melt modified by Al-10Sr, RE and Al-5Ti-B master alloys was poured into multi-step moulds made from three moulding sands, including quartz, alumina and chromite, to investigate comparatively the effects of different ...

Agglomeration Phenomena During Fluidized Bed Combustion/gasification of Biomass Fuels
The objective of this research is to investigate the occurrence of agglomeration phenomena during fluidized bed processing of biomass fuels. These are to be ascribed to the alkali content in biomass materials that gives rise to low melting compounds in ...

Abstract NASA's Curiosity rover is exploring a 5 km tall sedimentary mound that is hypothesized to record the transition from a warm and wet (phyllosilicate‐rich) to a cold and drier (sulfate‐rich) Mars. Evidence of magnesium sulfate‐bearing rock has shown that Curiosity has crossed through this phyllosilicate‐sulfate transition.
