More damning studies on graphene. ZEN needs to move past mak

[Bluehorseshoe75]

Geat article to read . Best comments attached. This guy really knows his stuff the chief for SI

ZEN has zero chance of making the graphene mask venture work after reading the article and great comments  They need to focus on the uniqueness and other opportunities before they loose it all chasing their tail.

Initial studies suggest that graphene is safe for long-term occupational exposure, but inhalation of graphene oxide should be avoided, depending on the size of the particles. Researchers from Graphene Flagship partners the University of Manchester, UK, the Karolinska Institute, Sweden, CNRS, the University of Strasbourg, France, and ICN2, Spain, found that pulmonary exposure to GO via intranasal instillation could cause size-dependent adverse effects on the lungs. However, nanometer-sized GO particles were found to be safe.

So as long as your GO particles are 1-X billionths in size you may be okay. The issue is, if they get bigger there is a problem. So three things have to be achieved here

1) Ensure the purchased GO from "the other source, whomever they are" has graphene oxide particles that fit this description and they do not exceed X or there is a problem

2) ZEN has to certify someone elses GO with HC as well as their own GO as being suitable

3) HC then has to review and accept the findings of the U of Man as their own, or its Human Trials for sure.

So this pop to 2.40 was likely based on people that thought this must be a get out of Jail Card, its not, it may have complicated things if both GOs, Company X and ZENs have large GO particles because now its a NO GO for sure if they do because you can be assured HC will accept the U of Man comment that big particles are bad, its how small is small enough.

If the stock did pop on this, then its going back to 1.76 or lower. Until ZEN makes a statement as to their GO particle size, to do that they would need to ensure their contract with their supplier stated clearly the acceptable particle size. My bet is it does not, in which case ZEN may have a bunch of Paid for GO that could be useless based on this article. Short is still the theme

Bluehorse can you explain what this means then: Initial studies suggest that graphene is safe for long-term occupational exposure, but inhalation of graphene oxide should be avoided, depending on the size of the particles.

To me, it seems that the following posting shows that the material is indeed quite small. https://www.zengraphene.com/zen-graphene-solutions-provides-update-on-graphene-based-coating-and-filtration-flow-rates/

"Small" 're read the article and understand what it says. Tell Francis and Greg to read it as well .  Another home office posting

A quote from https://onlinelibrary.wiley.com/doi/full/10.1002/advs.201903200 "In respect to the pulmonary route of exposure, graphene nanoplatelets (GNPs) have been the most widely studied GBMs to date, with several reports of transient inflammation after pulmonary exposure.[8-14] In addition, Roberts et al. demonstrated that GNPs with large lateral dimensions (5–20

Regardless of size, HC  and the FDA is NOT going to allow graphene in any breathable face mask. A tiny bit of arsenic won't kill you either but cumulatively you are toast. Just like graphene in face masks. If the ZEN mgmt can't see this , and they participate on all the bull boards.  This company will be chasing a dead dream. Focus on the real value of ZEN unique graphite
