will occupy the latice points that define the face centered cubic unit cell, with the zinc ions occupying the tetrahedral holes. Since there are four sulfide ions (FCC), we need only four zinc ions to ...

The simple cubic unit cell is delineated by eight atoms, which mark the actual cube. These are corner atoms, so each one only contributes one eighth of an atom to the unit cell, thus giving us only ...

It has a melting temperature of 660 C. The electronic configuration of Aluminum is (Ne)(3s) 2 (3p) 1, and it has an atomic radius of 0.143 nm. At room temperature Aluminum has the face-centered-cubic ...

The monoclinic structure has two unit cells. The primative cell (P) has fractional lattice points at the corners of the cell, and the base-centered cell (C) has additional fractional lattice points at ...

Nov. 12, 2024 — Researchers have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends ...

A cell's daily operations are accomplished through the biochemical reactions that take place within the cell. Reactions are turned on and off or sped up and slowed down according to the cell's ...

Cells are the smallest unit of life and the building blocks for all organisms. Each component of a cell has its own function. Animal and plant cells differ and they have similarities. Nucleus ...

Cell adhesion is the process by which cells form contacts with each other or with their substratum through specialized protein complexes. Intercellular adhesion can be mediated by adherens ...

In 2014, another group found out that while one enzyme named CDK1 prevents the loading of CENP-A during most of the cell ...

Take a research-focused master's course where you will learn through seminars, workshops, small group tutorials and research placements. Your research placement will be in the laboratory of a leading ...
