WebNine buffer solutions at three pH values, 5.4, 6.2, and 7.0, were prepared at three different ionic strengths: 0.29, 0.45, 0.71 M, as indicated in the Materials and Methods section. Prior to the 1H NMR measurements, the collagen fibers were hydrated by adding the buffer to the dried sample and left for two days at 4 °C. WebLattice energy is a calculation of ionic bond strength in an ionic compound. Also, it can be described as a method of measuring cohesive forces that bind ions. It gives insights into various characteristics, including its volatility, solubility, and durability of ionic solids. In an Ionic solid, lattice energy cannot be directly measured. raymond ford antioch
