Oh my gosh, incredible. Thank you for sharing this! I've got a microscope and I'm going to check out my distillers' sludge that's left. Thank you for giving me the idea! You are really great. Thanks again, DG in S.C.
What is the context here? I have no idea what the sample is, how it was prepared, or the time period elapsed. It’s my biggest criticism of what I call “Substack Science”. Science is supposed to be repeatable, right? Well Substack Science is just the opposite….not only will I not tell you what I did, I won’t give you a logical SOP to let you try it yourself. Not trying to start an argument, just frustrated at the microscopy community in general.
I have seen the same spike or needle crystals in lidocaine. I have seen them in NaCl as well. During the evaporation process the crystallization agents reach critical mass/super saturation occurs, then the crystals form. The asymmetrical unit is the smallest unit in the crystal. Crystallographers program the asymmetrical unit for the desired directed/programmed crystal expressions. We are sprayed with many ionic salts(heavy metals), They have different individual and combined crystal expressions. Like i said you can program crystal expression.
Asymmetric Unit Crystal
The asymmetric unit in crystallography is the smallest portion of a crystal structure to which symmetry operations can be applied to generate the complete unit cell. This concept is fundamental in understanding the structure and properties of crystals. Here are key points about the asymmetric unit:
Definition: The asymmetric unit is the smallest part of a crystal that, when combined with symmetry operations (such as rotations, translations, and screw axes), can generate the entire crystal structure.
Crystallographic Unit Cell: The asymmetric unit is contained within the crystallographic unit cell, which is the smallest repeating unit that, when translated in three dimensions, forms the entire crystal.
Symmetry Operations: Common symmetry operations include rotations, translations, and screw operations (which combine rotation and translation). These operations are applied to the asymmetric unit to recreate the entire crystal structure.
Crystallographic Databases: Structures analyzed by crystallographic methods are deposited in the Protein Data Bank (PDB) using the coordinates of the atoms in the asymmetric unit.
Biological Relevance: The asymmetric unit may not always represent the biologically functional unit. The biological assembly, which may be the same, smaller, or larger than the asymmetric unit, is often of interest in biological studies.
Wyckoff Positions: These are specific points within a unit cell that correspond to possible atomic sites dictated by the crystal’s symmetry. Each Wyckoff position has an associated multiplicity, indicating how many equivalent positions exist in the asymmetric unit.
Understanding the asymmetric unit is crucial for analyzing crystal structures and predicting physical properties such as optical activity and piezoelectricity.

I am always glad for any music, whether I
love it or not its a good balance to this devastation.....
best from OR
Add 1 cc of of chlorine dioxide
Solution, see what happens,
This is where the 36 trillion in national debt went. Guarantee dat.

I don't argue with anyone. Most know my approach/work, and I don't have to repeat my methods constantly.
