A rare feat: Material protects against both biological and chemical threats:

A Northwestern University research team has developed a versatile composite fabric that can deactivate both biological threats, such as the novel coronavirus that causes COVID-19, and chemical threats, such as those used in chemical warfare. A material that is effective against both classes of threats is rare.

The material also is reusable. It can be restored to its original state after the fabric has been exposed to threats by a simple bleach treatment.The promising fabric could be used in face masks and other protective clothing.

"Having a bifunctional material that has the ability to deactivate both chemical and biological toxic agents is crucial since the complexity to integrate multiple materials to do the job is high," said Northwestern's Omar Farha, an expert in metal-organic frameworks, or MOFs[*], which is the basis for the technology.

[...] The MOF/fiber composite builds on an earlier study in which Farha's team created a nanomaterial that deactivates toxic nerve agents. With some small manipulations, the researchers were able to also incorporate antiviral and antibacterial agents into the material.

MOFs are "sophisticated bath sponges," Farha said. The nano-sized materials are designed with a lot of holes that can capture gases, vapors and other agents the way a sponge captures water. In the new composite fabric, the cavities of the MOFs have catalysts that can deactivate toxic chemicals, viruses and bacteria. The porous nanomaterial can be easily coated on textile fibers.

    How well does this chlorine provide protection against chlorine gas?

      Moreover, the active chlorine loaded MOF/fiber composite selectively and rapidly degraded sulfur mustard and its chemical simulant 2-chloroethyl ethyl sulfide (CEES) with half-lives less than 3 minutes.

      It looks like they only tested it against two chemical agents.

      They say "bleach treatment". Chlorine or chlorine sulfide is only one bleaching agent. Hydrogen peroxide is probably the most used one for fabrics.

    I remember a few of these miraculous materials and in many cases there were some problems with them. So here it may be for example decay to some components being not so friendly to organism.
    An interesting example: Some time ago I was replacing an exhaust pipe from a gas water heater. I remember that in place in which it went to the wall, it was sealed by the bar of specific mineral cloth which prevented carbon monoxide from leaking if there was some problem with chimney. It was called... chryzotil? something like this, I don't know its English name. This thing has been used for 50 years or so, for this, for thermal isolation, for firemen suits, for keeping heaters from melting the floor if it was polymer, for lots of things. It was cheap as it was just dug from the ground. Now I was looking everywhere for it and... there is no more of it because it was too powdery when cut and its powders were toxic. And today everything must be single-use so it started to be a problem in early 2000s.
    So what you do now instead? You die of carbon monoxide poisoning. Great. Or you pay, and pay, and pay, for network of detectors, for monthly inspections, for bi-yearly camera inspections...

        The useful bit about "asbestos": (One of those things that causes cancer in more than just the State of California.)

        "Asbestos exposure is associated with parenchymal asbestosis, asbestos-related pleural abnormalities, peritoneal mesothelioma, and lung cancer, and it may be associated with cancer at some extra-thoracic sites".[14] In other scientific publications, epidemiologists have published peer reviewed scientific papers establishing that chrysotile is the main cause of pleural mesothelioma.[15][16][17]

        Chrysotile has been recommended for inclusion in the Rotterdam Convention on Prior Informed Consent,[18] an international treaty that restricts the global trade in hazardous materials.

    ANSWER = roughly 99++% across ALL age groups (or close to it)

    pericarditis
    myocarditis

    NERVOUS "twitch" disorders (sp? gillian barre etc.)

    They don't KNOW WHAT THEY'RE DOING (or do & want to kill you)!

    PCR test cycles TURNED UP TOO HIGH in cycling per Kary Mullis the NOBEL LAUREATE who was awarded the NOBEL PRIZE for that test (nobody knows it better than he - HE INVENTED IT) DID OCCUR & the fact "new tests" ARE out PROVES IT - but those that took the shot based on FALSE POSITIVE RESULTS I list above ARE IN DEEP SHIT (dead).
