Recent pegmatite-hosted spodumene discoveries in Western Australia: insights for lithium exploration in Australia and globally
ABSTRACT The discovery and development of world-class Lithium–Caesium–Tantalum (LCT) spodumene-bearing pegmatites in Western Australia underpins growth of a significant new sector of its mining
Mesoporous Poly(melamine-co-formaldehyde) Particles for Efficient and Selective Phosphate and Sulfate Removal
To face the harsh acidic conditions, an adsorber material with a high chemical resistivity is beneficial and Poly(melamine-co-formaldehyde) (PMF) sustains these conditions whilst its very high amount of nitrogen functionalities act as efficient adsorption sides.
Properties of Structural Lightweight Aggregate Concrete Based on Sintered Fly Ash and Modified with Exfoliated Vermiculite
The purpose of the research was to determine the possibility of using sintered fly ash as alternative aggregate in structural concrete and the impact of sintering fly ash lightweight aggregate on its physical, mechanical and durability properties.
Geochemical Assessment and Mobility of Undesired Elements in the Sludge of the Phosphate Industry of Gafsa-Metlaoui Basin, (Southern Tunisia)
The raw phosphates in the Gafsa-Metlaoui phosphate basin are valorized by wet processes that are performed in the laundries of the Gafsa Phosphates Company (CPG, Gafsa, Tunisia) to reach market
Environmental impacts of conventional and additive manufacturing for the production of Ti-6Al-4V knee implant: a life cycle approach
This paper explores whether additive manufacturing (AM) is more environmentally friendly than conventional manufacturing (CM) for the production of medical implants. The environmental impact of
Mimicking the Constrained Geometry of a Nitrogen-Fixation Intermediate.
It is shown in the present study that use of a geometrically flexible, dinucleating macrocycle allows for the formation of a bridging N2 ligand with an unusual Fe-CtN2-Fe angle of 150°, a geometry that approximates the α-N2 binding mode on Fe(111) surfaces that precedes N2 bond cleavage.
