rotundone rotor
Many people hear have read about molecular motors as well as rotaxanes It occured to me that compounds like rotundone which is detectable at picogram quantities could be used as a way of communicating state to a larger organism
Some aroma testers were able to sniff out the sesquiterpene at concentrations as low as 0.4 ng/L in water which if we presume a thousandth of a liter is .4 picograms yet this is a scent thus an entire cc of water vapor typically occupies near an 18th of a gas mole volume which is 22.4 liters Thats near 400 femtograms per liter At 2 or three ccs per sniff Thus rotrundone is detectable near a femtogram or two per scent test
thus tiny rotaxanes could rotate to bring a linked molecule of rotundone to their surface creating immediate human detectability as a scent
also many chemicals have their receptor aspects modified with halogenation Splenda is chlorosucrose that is hundreds of times sweeter than sugar; it is possible that halogenated rotundone could have a different scent of be dozens or hundreds of times more detectable That would make chlororotundones detectable at the attogram quantity

all of these molecules are active at nanograms or picograms per liter All appear to be molecules potentially amplifiable with chlorinatiom
while a human detects a molecular rotor that puts up these kind of compounds as a kind of display we can think about what kind of machine readable molecule might be most efficient Quantum dots produced with lithography are generally much larger than molecular motors thus fluorophores linked to molecular motors appear to be highly readable nanomachine outputs
nanoengraved aggregate
You may have read that nano sized fumed silica particles are a part of eco friendly cement that uses much less energy
It occured to me that the aggregate, that is the mineral blobs, could be laser engraved to have a surface that is particularly effective at cementation
Now there is an opportunity to either laser engrave the aggregate to have a nanotextured surface just like a hologram or quite possible to use ultrasonics to create a regular pattern of ndentations
This kind of thing matters as to promote nanotechnology creating a nanotechnology application that affects literally trillions or billions of tons of material advances nanotechnological industry generally Also I read that cement production is associated with an amount of greenhouse gases about a quarter or a third that of vehicles, the fumed silica cement saves 4/5 of that energy thus nanoengraved aggregate might grab another chunk It would be rather bold to suggest an entire pt of greenhouse gases could be abated with nanoengraved aggregate yet it is possible
The nanotechnology of the area above highest occupied molecular orbital
view this
then view this
then think on the ranges of effective fields
then think of the length of a molecule spanning these ranges
then think of side groups as knob twiddles (protein conformation)
viewing the strange attractor effect we see the way under certain circumstances a particle given a large number of choice paths converge on a particular value near the strange attractor Actual physical chemists have written equations as well as software about how atoms meet up to form similar structures even though there are literally moles (10^23) factorial of possibilities
That relationship can be restated as mathematical centers of activity that pass through regions of deterministic regions as well as partially deterministic strange attractor regions as a kind of series of bands around an atom or molecule
Right now there are gorgeous energy distribution diagrams like
I think that above this region there are strange attractor regions (that "funnel" rather than Gaussian pachinko)flanked with translationally linear regionsNow what this means to a nanotechnologist is that part of the aluminum supercluster or a polymer could span deterministic as well as partially deterministic regions at the same time If you've walked on steps that are just the right spacing for your stride or absolutely at different spacing you can see how a molecule could either jiggle relentlessly or act linear depending on electron potential zone fit outside the atoms That is a molecule spanning multiple ranges could suddenly be ordered or jiggly with the pitch of its side groups liquid crystals as well as polymers could test this idea wanton jiggly noodles are much sexier than rigid linearities yet nanoengineers would like to draw things with CAD that just work controlling zone pitch above the highest occupied molecular orbitals could give them zones of predictability to do nanoengineering
any ideas appreciated
