{eq}\displaystyle \text{Packing Fraction} = \frac{\text{Effective volume occupied by the atoms in a unit cell}}{\text{Volume of the unit cell}}. {/eq} Answer and Explanation: (a) A two-dimensional...
b. The (111) plane for the BCC crystal structure Packing of atoms in the unit cell. Atoms have a different arrangement in the element which can be a simple cubic cell, body-centered cubic cell or face-centered cubic cell. Each arr...
To assess the importance of terminal spreading along medial sets, we turn to the SST of DG (and its competitor phases Hex and Lam)26,27,38. Each block copolymer consists ofNsegments, a fractionfof which are A-type, with segment lengthsaAandaB. As shown schematically in Fig.2, microphase...
Results: Both, A-RTS and SEM, show that with the vertical convective self-assembly method, with the appropriate parameters of temperature of evaporation (60°C), volume fraction of the colloidal suspension (0.2% w/w) and acidity (pH=6), highly orderedclose packedface centeredcubic(fcc) SiO2...
