Aldrich Materials Science offers precisely manufactured monodisperse silver nanoparticles that are free from agglomeration, making them ideal for research, development, and use in a variety of innovative applications (Figure 1).
Silver nanoparticles are extraordinarily efficient at absorbing and scattering light and, unlike many dyes and pigments, have a color that depends upon the size and the shape of the particle.
In fact, silver nanoparticles can have effective extinction (scattering + absorption) cross sections up to ten times larger than their physical cross section.
When 60 nm silver nanoparticles are illuminated with white light they appear as bright blue point source scatterers under a dark field microscope (Figure 2, right). The bright blue color is due to an SPR that is peaked at a 450 nm wavelength. A unique property of spherical silver nanoparticles is that this SPR peak wavelength can be tuned from 400 nm (violet light) to 530 nm (green light) by changing the particle size and the local refractive index near the particle surface.
When nanoparticles are in solution, molecules associate with the nanoparticle surface to establish a double layer of charge that stabilizes the particles and prevents aggregation. Aldrich Materials Science offers several silver nanoparticles suspended in a dilute aqueous citrate buffer, which weakly associates with the nanoparticle surface.
Silver nanoparticles have unique optical, electrical, and thermal properties and are being incorporated into products that range from photovoltaics to biological and chemical sensors. Examples include conductive inks, pastes and fillers which utilize silver nanoparticles for their high electrical conductivity, stability, and low sintering temperatures. Additional applications include molecular diagnostics and photonic devices, which take advantage of the novel optical properties of these nanomaterials. An increasingly common application is the use of silver nanoparticles for antimicrobial coatings, and many textiles, keyboards, wound dressings, and biomedical devices now contain silver nanoparticles that continuously release a low level of silver ions to provide protection against bacteria.
Silver Nanoparticle Applications
Silver nanoparticles are being used in numerous technologies and incorporated into a wide array of consumer products that take advantage of their desirable optical, conductive, and antibacterial properties.
•Diagnostic Applications: Silver nanoparticles are used in biosensors and numerous assays where the silver nanoparticle materials can be used as biological tags for quantitative detection.
•Antibacterial Applications: Silver nanoparticles are incorporated in apparel, footwear, paints, wound dressings, appliances, cosmetics, and plastics for their antibacterial properties.
•Conductive Applications: Silver nanoparticles are used in conductive inks and integrated into composites to enhance thermal and electrical conductivity.
•Optical Applications: Silver nanoparticles are used to efficiently harvest light and for enhanced optical spectroscopies including metal-enhanced fluorescence (MEF) and surface-enhanced Raman scattering (SERS).
Silver Nanoparticles for Nanotoxicology Research
There is growing interest in understanding the relationship between the physical and chemical properties of nanomaterials and their potential risk to the environment and human health. The availability of panels of nanoparticles where the size, shape, and surface of the nanoparticles are precisely controlled allows for the better correlation of nanoparticle properties to their toxicological effects. Sets of monodisperse, unaggregated, nanoparticles with precisely defined physical and chemical characteristics provide researchers with materials that can be used to understand how nanoparticles interact with biological systems and the environment.
So if someone wanted a fake blue sky, could it be done? Well, yeah, I mean if we can create fake clouds from jet emissions, why not just fake the entire sky and do away with the chemtrails or continue with them behind the fake sky?
This particular company puts them into glass bottles but I think glass lined canisters for flaming out of drones would be an easy fix to the packaging process. This would put them into the current extremely high tech world of a global operation in progress that goes by the code name of 'cloud seeding.' Or, in some other countries as 'rainmaking' or even 'royal rainmaking.'
Cloud seeding, a form of intentional weather modification, is the attempt to change the amount or type of precipitation that falls from clouds, by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud. The usual intent is to increase precipitation (rain or snow), but hail and fog suppression are also widely practiced in airports.
I take it you missed the page that you can actually purchase items from this company...
I think you missed a few things.....
I am going to bet you have some silver nanoparticles on or around you as you sit there....
Cloud seeding is not a code word for anything as it is and does what the name suggests. Now this is what cloudseeding does...

I do have a question for you based on your input:
You provided a link showing what cloud seeding is attempting to do. It would be interesting to know what it actually does. Would you have any information on that?
Cloud seeding is not a code word
The history of cloud seeding has experienced uncertain results because it can never be known whether a cloud that rains after seeding might have rained anyway. This is because seeding is performed on clouds that look like they have some potential for producing rain.
For a while, there was growing hope that weather modification in the form of cloud seeding could provide more water for the Edwards Aquifer and also potentially reduce agricultural demand. In 2003, scientists at the National Academy of Sciences concluded there is no scientific evidence that it works (11). The American Meteorological Society's official position is that there has been some statistical evidence showing a 10 percent increase in precipitation after cloud-seeding, but no conclusive cause and effect.
Cloud seeding got its start in 1946 when Dr. Vincent J. Schaefer, working at the General Electric Laboratory in New York, was involved with research to create artificial clouds in a chilled chamber.
In 2007, the EAA approved cloud seeding efforts for the ninth year in a row, and for the first time the program included a method to statistically evaluate the project's effectiveness. Four Board members voted against continuing the program, saying their was evidence that cloud seeding could actually decrease rainfall by accident, and they also had concerns about the EAA paying for scientific studies to investigate something the National Academy had already concluded doesn't work (13).
Scientific assessment of the South African, Mexican, Thailand, and Indian Cloud Seeding experiments concludes cloud seeding is still an unproved science with untold effects.
PDF: Critical Assessment of Hygroscopic Seeding of Convective Clouds for Rainfall Enhancement – (.ORG) American Meteorological Society It was concluded that tests conducted so far have not yet provided either the statistical or physical evidence required to establish that the seeding concepts have been scientifically proven.
By reducing the time required for the precipitation process to evolve with respect to the time available, rain efficiency will increase such that the treated clouds will precipitate earlier and with greater intensity than they would naturally, but they may not necessarily produce more rain than they eventually would naturally.
What have we learned? Cloud seeding is an unproven science, even after 60 years. Further, Texas, the most severe drought stricken area in America, is also the state that has funded the most cloud seeding projects since 2004.

Well what is it then?
Shining your toy laser in the sky is no silly game, according to the FBI. In fact, it can result in felony charges.
The offense, a federal crime, carries a maximum sentence of 20 years in prison, indicating the seriousness of the infraction.
The state where the incident occurred currently has no state laws prohibiting this action, but FBI officials indicated that they are committed to stopping this dangerous practice.
also i see you're not getting meaning of picture as a possible reason for geo-engineering/chemtrails
Keep your head down and go about your business while we engage in rainmaking which has never been scientifically proven to work.
With five months to go before the Summer Games come to Beijing, Chinese scientists say they are confident they can keep rain away from the opening ceremony, or summon a storm on cue to clear the city's choking pollution. www.usatoday.com...
During October 1966, Project Popeye was tested in a strip of the Laos panhandle east of the Bolovens Plateau in the Se Kong River valley. The test was conducted by personnel from the Naval Ordnance Test Station located at China Lake California. Fifty cloud seeding experiments were conducted with the result that 82% of the clouds produced rain within a brief period after having been seeded. It was claimed that one of the clouds drifted across the Vietnam border and dropped nine inches of rain on a US special forces camp over a four hour period. After the successful completion of the test phase, Project Popeye transitioned from an experiment to an operational program of the U.S. Defense department.
The Operation's Objectives
Operation Popeye goal was to increase rainfall in carefully selected areas to deny the Vietnamese enemy, namely military supply trucks, the use of roads by: [3]
Softening road surfaces
Causing landslides along roadways
Washing out river crossings
Maintain saturated soil conditions beyond the normal time span.

Not true, cloud seeding has been proven to work and has been employed recently in China to clear the smoggy air for the Olympics in Beijing.

Did you know the United Nations passed a Weather Warfare Treaty (download) in 1977? en.wikipedia.org...
Of course you didn’t, that’s the point. They don’t want the public to know that military’s and government’s all over the world are experimenting with our weather.
That fact that there is a treaty proves that they had to pass laws to regulate people. After all you don’t pass laws for things that don’t exist!
This is taken from Article 1 of the treaty
Article I1. Each State Party to this Convention undertakes not to engage in military or any other hostile use of environmental modification techniques having widespread, long-lasting or severe effects as the means of destruction, damage or injury to any other State Party.
This is taken from Article 2 of the treaty
It is the understanding of the Committee that the following examples are illustrative of phenomena that could be caused by the use of environmental modification techniques as defined in Article II of the Convention: earthquakes, tsunamis; an upset in the ecological balance of a region; changes in weather patterns (clouds, precipitation, cyclones of various types and tornadic storms); changes in climate patterns; changes in ocean currents; changes in the state of the ozone layer; and changes in the state of the ionosphere.
Just look at the historical weather we have had in the last couple of years. Katrina, the California wildfires, an earthquake in Indiana!, the flooding in the Iowa and the Midwest.
