Due to the nature of their material properties, Calcium Fluoride (CaF2), Magnesium Fluoride (MgF2), and Potassium Dihydrogen Phosphate (KDP) are widely used for industrial purposes. A better understanding of the mechanical properties of these materials is of technological and scientific importance. The indentation nano-mechanical response of CaF2 (cubic), MgF2 (tetragonal), and KDP (tetragonal)...

This work investigates nano-fibrillated cellulose (NFC) as a component in mineral pigment paper coating. In this work, bleached Eucalyptus pulp was pretreated by TEMPO (2,2,6,6-tetramethyl-1-piperdinyloxy)-mediated oxidation. The oxidized pulp was then isolated to obtain NFC by sonication. Aqueous coating colors consisting of calcium carbonate, clay, carboxylated butadiene-styrene latex, additi...

Our research objective is to foster a multiscale understanding of fine recycled aggregate concrete using bottom-up approach. We investigate the influence aggregates on structure calcium-silicate-hydrates. To this end, we introduce new thought model for with four levels structural hierarchy: beam, mortar, binder, and C–S–H gel levels. characterize behavior natural sand analytical methods such as...

Conventional protein kinase Cs (cPKCs) are key signaling proteins for transducing intracellular Ca2+ signals into downstream phosphorylation events. However, the lifetime of individual membrane-bound activated cPKCs is an order of magnitude shorter than the average time needed for target-protein phosphorylation. Here, we employed intermolecular Förster resonance energy transfer (FRET) in living...

The nanocomposite web of calcium alginate and polyvinyl alcohol with varying proportion has been prepared by electrospinning and its application for wound healing is examined. Scanning electron microscope and Fourier transform infrared spectroscopy have been used to characterize the morphology and molecular fingerprint. The water vapour transmission rate of the blended nanofibre composite web h...

Transient elevations in cytoplasmic Ca(2+) trigger a multitude of Ca(2+)-dependent processes in CNS neurons and many other cell types. The specificity, speed, and reliability of these processes is achieved and ensured by tightly restricting Ca(2+) signals to very local spatiotemporal domains, "Ca(2+) nano- and microdomains," that are centered around Ca(2+)-permeable channels. This arrangement r...

Calcium carbonate (CaCO3) is an abundant mineral that has several uses in paper [1], Portland cement [2] and steel making [3], as agricultural input for soil modification [4], and food additive in soy milk and dairy products. Due to its high biocompatibility, CaCO3 is also employed in many pharmaceutical (anti-acid, dietary supplement for child and postmenopausal women), biological (scaffolds f...

The new triphasic potassium−substituted hydroxyapatite (KHAP), β−tricalcium phosphate (β−TCP), and calcium pyrophosphate (CPP) proportions using easy sol−gel method were synthesized. The prepared powders was characterized by X–ray diffraction (XRD), Fourier transform infrared (FTIR), Differential thermal behavior (DTA) analysis, Energy Dispersive X–ray Analysis (EDXA), and Brunauer–Emmett–Telle...
