1. Crustal evolution of the Arabian–Nubian Shield : Insights from zircon geochronology and Nd–Hf–O isotopes
Abstract : The Arabian–Nubian Shield (ANS) represents a major site of juvenile Neoproterozoic crustal addition on Earth and documents Neoproterozoic tectonics bracketed by two supercontinent cycles, namely the fragmentation of Rodinia and the amalgamation of Gondwana. There is general consensus that the ANS formed by juvenile magmatic arc accretion and subsequent shield–wide post–tectonic magmatism. READ MORE

2. Design and synthesis of xyloglucan oligosaccharides : structure-function studies and application of xyloglucan endotransglycosylase PttXET16A
Abstract : Primary cell walls are a composite of cellulose microfibrilsand hemicelluloses. Xyloglucan is the principal hemicelluloseof primary cell walls of dicotyledons. Xyloglucanendotransglycosylases (XETs) cleave and religate xyloglucanpolymers in plant cell walls. READ MORE

4. Leukotriene A4 hydrolase : identification of amino acid residues involved in catalyses and substrate-mediated inactivation
Abstract : Leukotriene (LT) A4 hydrolase catalyzes the committed step in the biosynthesis of LTB4, a classical chemoattractant and immuine-modulating lipid mediator involved in inflammation, host-defense against infections, and systemic, PAF-mediated, lethal shock. LTA4 hydrolase is a bifunctional zinc metalloenzyme with a chloride stimulated arginyl aminopeptidase activity. READ MORE

5. Tools for characterizing performance degradation in lithium-ion batteries
Abstract : Lithium-ion batteries have enabled vast societal changes, ranging in scale from the adoption of personal electronics to electromobility and grid-scale, renewable energy storage. However, all applications face performance fade over time, observed as losses of battery capacity and power. READ MORE
