Lieutenant Colonel. Always capitalized.
Actually, only capitalize both words when used as part of a formal title, e.g. Lieutenant Colonel John Kurtz, US Army, or when used as a proper noun in place of an actual name, e.g. "We reported that the Captain had died to the Lieutenant Colonel" (where "Captain" and "Lieutenant Colonel" were specific people, not just generic ranks).
In all other cases, the "L" should be capitalized (but the "C" should not) when it starts the beginning of a sentence. Neither should be capitalized when referring to the generic rank, e.g. "The meeting looked like a convocation of lieutenant colonels." Also, in that example, note how "lieutenant colonel" is puralized - adding an "s" to "colonel", not to "lieutenant".
The term "lieutenant" originates from the French word "lieutenant," which means "to hold" or "to place." It combines "lieu" (place) and "tenant" (holding), indicating someone who holds a position in the absence of a superior. The alternative spelling "lefttenant" is derived from Middle English and reflects the pronunciation of the word in certain regions, particularly in Britain. Over time, "lieutenant" became the standard spelling in most English-speaking countries, while "lefttenant" remained more common in British usage.

Yes. The principle is well-known and thoroughly attested: Bad money drives out good.
The proper spelling is aerogel. It is not specially capitalized at the beginning or in the middle, nor should it contain a hyphen or a space. The word has been in technical usage since 1931 and is not a tradename or proper noun. Common incorrect spellings include "Aerogel', "AeroGel", "aero-gel", "aero gel", and alternative phonetic spellings such as "airojell" and "aerojell".

Colonel comes from Old Italian colonello, commander of a column of troops, which in turn derives from colonna,column. English usage followed Spanish practice (also a French variant) and spelled the word "coronel," pronounced the way it looks. Eventually this was corrupted to ker-nel. When the written version became "colonel" (reflecting its Latin origin), the "kernel" pronunciation remained.
