  2. Multipurpose Applied Physics Lattice Experiment - Wikipedia

    en.wikipedia.org/wiki/Multipurpose_Applied...

    An operational license for the MAPLE I reactor was granted in 1999, and the reactor went critical for the first time in early 2000. MAPLE II followed in the fall of 2003. Problems with the reactors during the testing period, most notably an unexpected positive power co-efficient of reactivity , led to the cancellation of the project in 2008 and ...

    18-Crown-6 can be synthesized by the Williamson ether synthesis using potassium ion as the template cation. Structure of nickel-aquo nitrate complex of the ligand derived from the templated trimerization of 2-aminobenzaldehyde. [5] The phosphorus analogue of an aza crown can be prepared by a template reaction. [6]

    [[Category:Chemistry templates]] to the <includeonly> section at the bottom of that page. Otherwise, add <noinclude>[[Category:Chemistry templates]]</noinclude> to the end of the template code, making sure it starts on the same line as the code's last character.

  5. Lattice energy - Wikipedia

    en.wikipedia.org/wiki/Lattice_energy

    The concept of lattice energy was originally applied to the formation of compounds with structures like rocksalt and sphalerite where the ions occupy high-symmetry crystal lattice sites. In the case of NaCl, lattice energy is the energy change of the reaction Na + (g) + Cl − (g) → NaCl (s) which amounts to −786 kJ/mol. [2]

  6. Crystal structure - Wikipedia

    The hpc lattice (left) and the ccf lattice (right) The principles involved can be understood by considering the most efficient way of packing together equal-sized spheres and stacking close-packed atomic planes in three dimensions. For example, if plane A lies beneath plane B, there are two possible ways of placing an additional atom on top of ...

    en.wikipedia.org/wiki/Lab_notebook

    Chemistry stencils that used to be used for drawing equipment in lab notebooks. A laboratory notebook ( colloq. lab notebook or lab book ) is a primary record of research . Researchers use a lab notebook to document their hypotheses , experiments and initial analysis or interpretation of these experiments.

  8. Lattice constant - Wikipedia

    en.wikipedia.org/wiki/Lattice_constant

    Unit cell definition using parallelepiped with lengths a, b, c and angles between the sides given by α, β, γ [1]. A lattice constant or lattice parameter is one of the physical dimensions and angles that determine the geometry of the unit cells in a crystal lattice, and is proportional to the distance between atoms in the crystal.
