One top area of interest is the use of carbon nanotubes to increase reliability and effectiveness of infrared obscuration by as much as a factor of 10 over current technologies.
Doug DuFaux, director of innovations at Buffalo, N.Y.-based nanotechnology firm Nanodynamics, Inc. told Special Operations Technology that, while the ability is not there yet, the potential for manipulating one-nanometer pellets of carbon to obscure infrared signals is immense.
John is currently leading projects that utilize metal nanoparticles as novel obscurants to block visible, near-IR, and mid-IR regions of the spectrum.
Because of that uncertainty, the researchers hope to pressure companies developing carbon nanotube-based materials to reveal whether they are using longer strands such as the ones that appear to act like asbestos — which was once a wonder material, too, before its cancerous consequences were discovered.
Study: Carbon nanotubes mimic asbestos in mouse tests
And in research in his labs, in which mice are not injected with nanotubes but breathe it into their lungs — the way people would presumably be exposed — the animals developed inflammation that peaked within seven days of exposure, and returned to normal within one or two months.
"Whether the material is asbestos-like is still a question to be debated," Castranova said. "Having a panic that you have the next asbestos is a little bit premature in my view."

I'm not sure those images are even really of chaff, it's more the flare and the flare's smoke that you are seeing. Actual chaff by itself would be pretty much invisible. I've been unable to find a photo of any modern chaff being dispensed without a flare - probably because you'd not see anything.

The information you present is basically a WWII obscurant redux.

The pictures you show could also apply to aerial cloud seeding using flares or ignitable pots. IMO, chaff, as in obscurants, and chemtrails and cloud seeding are joined at the hip. So I'm strongly disagreeing right off the bat with any statement that they're not.

Breathing aluminum is not good for us, regardless of how much aluminum exists in the soil.

Cloud seeding materials are toxic and have a bad impact on aquatic life. Carbon nanotubes are just beginning to be studied and initial reports indicate that this will be another asbestos. If so, decades will pass before regulation vindicates those with health complaints.
Placing obscurants between the target and the viewer will degrade the performance of these sensors. Target acquisition and identification depend on the contrast between the target and its background and the brightness of the target. Smoke and dust will decrease this contrast and brightness by attenuating light reflected from the target. Rain, snow, fog, and haze will also degrade the performance of these systems. To use an obscurant against these sensors, place the obscurant in the line of sight between the target and the observer. Obscuration use in moonlight can also degrade the contrast of target and background. We can further degrade the contrast of a target with its background by the light from the sun that fails directly onto the obscurant and is then scattered into the line of sight. The amount of degradation depends on the position of the sun and the depth of the obscurant cloud. Degradation is greatest when both sun and target have about the same line of sight to the observer or viewer. Considerable degradation can also occur when the sun is directly behind the observer or viewer.
Nanomaterials are not simply another step in miniaturization, but a different arena entirely; the nanoworld lies midway between the scale of atomic and quantum phenomena, and the scale of bulk materials. At the nanomaterial level, some material properties are affected by the laws of atomic physics, rather than behaving as traditional bulk materials do.
Nanomaterials have actually been produced and used by humans for hundreds of years - the beautiful ruby red color of some glass is due to gold nanoparticles trapped in the glass matrix. The decorative glaze known as luster, found on some medieval pottery, contains metallic spherical nanoparticles dispersed in a complex way in the glaze, which give rise to its special optical properties. The techniques used to produce these materials were considered trade secrets at the time, and are not wholly understood even now.
The most energetic research probably concerns carbon nanotubes.
Nanocomputers based on carbon nanotubes have already been demonstrated.

I'm kind of surprised at this retro discussion. Light scattering and obscuring effects of, for instance, smoke and fog and thin cirrus have been observed by everyone. The release of radar jamming obscurants or obscurants to jam more sophisticated instruments or the use of cloaking particles cannot be used to say that there are no visual effects. Really - you all are too literal or you all are just walking obscurants yourselves.
Cloud seeding (and I include a lot of weather modification including moving radioactive clouds in that) and chemtrails and chaff and military obscurants in general have some things in common. They all obscure.

Saying that nano size obscurants are invisible to the naked eye is garbled, bizarre and absurd.

Saying that a release of nano size particle obscurants would not create a white plume is also garbled, bizarre and absurd. Nano particle reactions with atmosphere and within atmospherically released suspensions should be infinite, or seemingly so.
