Tuning Cation Disorder in LiNi0.5Mn1.5O4 via Room Temperature Continuous‐Flow Co‐Precipitation and Controlled Heat Treatment

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
LiNi0.5Mn1.5O4 (LNMO) precursors were produced at room temperature by Ambient Continuous Turbulent In‐line Mixing (ACTIM) at rates of up to 0.42 kg h−1. The final heat treatment step at 650, 700, or 750 °C, altered cation disorder and the electrochemical behavior of the LNMO cathodes, while the effect of adding MWCNTs to the electrodes, was also ...

Catalytic Pyrolysis of Torrefied Municipal Solid Waste Using Local Iron for Improved Bio‐Oil Yield and Energy Efficiency

open access: yesEnergy Science &Engineering, EarlyView.
Catalytic Pyrolysis of Torrefied Municipal Solid Waste to sustainable bio‐oil. ABSTRACT South Africa faces growing municipal solid waste (MSW) accumulation and energy insecurity due to fossil fuel dependence. Torrefaction improves MSW for waste‐to‐energy use, while conventional pyrolysis produces low‐quality oxygen‐rich bio‐oil.

Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

open access: yesGeological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Late Pleistocene Volcanic Rocks From Tengchong Volcanic Field at SE Tibetan Plateau: Constraints on Petrogenesis and Mantle and Crustal Processes

open access: yesGeological Journal, EarlyView.
Early zircon saturation and crystallisation occur in mafic (52–54 wt.% SiO2) lavas at Tengchong volcanic field. These early formed zircons with high δ18O (6.6‰–7.9‰) indicates mantle enrichment by subducted supracrustal materials. ABSTRACT Late Pleistocene (< 0.2 Ma) mafic and evolved volcanic rocks occur in northern Tengchong Volcanic Field, SE ...

A Reassessment of Petrochemistry of ~1.2 Ga Tonalitic Rocks of the Northern Tugela Terrane, Natal Metamorphic Belt, South Africa: Further Constraints on the Evolution of This Belt

open access: yesGeological Journal, EarlyView.
Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.

Apatite in Carbonatite Preserving Primary Magmatic, Post‐Magmatic Overgrowth, and Post India‐Asia Collision‐Related Hydrothermal Alteration: Evidenced From U–Pb Isotope and Trace Element Geochemistry

open access: yesGeological Journal, EarlyView.
U–Pb isotope and trace element geochemistry of apatite from carbonatites of Peshawar Plain Alkaline Igneous Province, western Himalaya shows Permo‐Carboniferous magmatism, an additional magmatic pulse during Cretaceous, and post‐magmatic hydrothermal/metasomatism during Oligocene. ABSTRACT U–Pb isotope and trace element geochemistry of apatite combined

CO2 capture by accelerated weathering of limestone using waste limestone at elevated CO2 concentrations

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Accelerated weathering of limestone (AWL) using waste limestone (WL) for industrially relevant CO2 capture remains underexplored. Previous studies on potable water‐operated AWL have mainly examined idealised conditions, such as the use of high‐purity limestone or relatively low CO2 concentrations, which may not reflect selected ...

Jewelled Byzantine and Medieval Reliquaries of the True Cross: Peridots and Other Gemstones in Material and Symbolic Perspective

open access: yesJournal of Raman Spectroscopy, EarlyView.
An interdisciplinary in situ study of jewelled reliquaries of the True Cross integrates gemmology and portable analytical techniques, revealing new evidence on the identification and symbolic role of peridots and other gemstones. ABSTRACT Jewelled crosses containing relics of the True Cross occupy a central position in the devotional, artistic and ...

Loss of zinc from zinc‐biofortified rice and conventional rice varieties due to various cooking techniques practiced in rural Bangladesh

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Zinc‐biofortified rice has the potential to provide a sustainable solution for zinc deficiency, particularly in Asian countries where rice is the primary staple food. However, cooking of raw rice is associated with some loss of micronutrients, including zinc.
