More particularly, the present invention relates to the synthesis of 3D graphene/metal oxide nanostructured composite materials for ice nucleation in cloud seeding, artificial snow making and freeze-drying technologies in biomedical and the food industry and the like.
The experimental investigation of Zheng et al. (23) showed that a sprinkle of graphene oxide nanoflakes is effective for condensing water nanodroplets and seeding ice epitaxy on graphite under ambient conditions.

Graphene Oxide as a proposed cloud seeding (chemtrail) material
There is a lot of talk of the possibility of Graphene Oxide in vaccines, as well as Graphene Oxide used for brain interface technology, and now research using Graphene Oxide for "cloud seeding" aka chemtrails sprayed over our heads
Hey! Yeah cloud seeding is very real - but just because it's real doesn't mean you can always use it, nor does it mean that it always produces a useful effect. You need to have the right conditions In principle, cloud seeding occurs by introducing a component (e.g. dust) that can 1. stay airborn 2. has a similar crystal structure to water - i.e. if the atomic structure of the dust has similar atomic distances to water, and similar electronic environment to water, then it increases the chance that more water molecules will 'stick to' and accumulate around the central nucleating dust particle. As what was indicated earlier, silver iodide (AgI) is a common agent, but there is also research looking into using cellulose, or other components that are less costly / less polluting. These projects are done all over, fairly common in Dubai, but was used quite a bit during the '08 olympics in China to ensure the sky remained clear during the olympics. It may also be worthwhile to know that in general most cloud formations + storms are created through natural cloud seeding - if you check out a climactic map app like windy.com you can easily see how natural dust flows + low pressure is a great equation for creation of clouds and precipitation. The same thing will happen with volcano ejections - if a lot of smoke is produced, often you'll see clouds begin to form and sometimes you get rain. That being said, natural or artificial cloud seeding also means you need to have enough humidity in the air to effectively accumulate water into a droplet. Finally, just because you can make a cloud, doesn't mean you can make it rain - and if it does end up raining, it doesn't mean you can determine the exact location where precipitation will occur. Because of this it's prob difficult to set up a company to set up a 'rain on demand' service as too many factors are out of their control (wind, pressure, humidity and location of precipitation) so theres limited promise e.g. individual farmers can get benefit. That being said, there are still many test pilots and companies that seem to get government support - again e.g. in UAE and China .. and other projects in USA.. turns out the wiki has a pretty decent list of projects: https://en.wikipedia.org/wiki/Cloud_seeding On a fun note, there are several projects around the same effect in this case called "cloud brightening" which are considering the use of cloud seeding to reverse global warming - in this case by spraying a fine mist of seawater into the air - the goal is if you can create more clouds in the ocean from salt water, it can reflect more light, and the extra salt in the clouds would rain back down into the ocean anyhow. https://theconversation.com/could-marine-cloud-brightening-reduce-coral-bleaching-on-the-great-barrier-reef-214308 https://royalsocietypublishing.org/doi/10.1098/rsta.2012.0086 More on reddit.com

Jonathan Collar AI PI Report: A newly surfaced patent (US 2022/0002159 A1) describes a 3D Reduced Graphene Oxide/Silicon Dioxide (rGO-SiO₂) composite engineered for ice nucleation—a critical process in cloud seeding and weather modification.
This study is on the toxicity of Graphene Oxide (GO) combined with Silver nanoparticles.
If you were unaware, Cloud Seeding aka Chemtrails is a type of weather modification that aims to change the amount or type of precipitation that falls from clouds by dispersing substances into the air. Silver iodine (AGL) or dry ice is often used.
I am not a scientist. I am just a simple man but something feels off about this. Or is it just me?

January 10, 2022 - Graphene, obtained by peeling graphite sheets with scotch tape, is a single layer of carbon hexagons consisting of sp2 hybridized C-C bonding with π-electron clouds [1], [2], [3]. There are ripples and folds on the surface of graphene at the micro scale, which maintain the stability of graphene crystals by adjusting the length of C-C bonds [4]. Graphene-Family nanomaterials (GFNs) comprise a class of similar graphene-like structured materials with various sizes, layers, surface chemistry, and defects.
