Metal–organic framework

So if they're producing methane or producing something else, that could be bad for our environment.

I do think MOFs could be the answer, so metal organic framework.

So they're like those cages we discussed before.

So they would essentially trap the plastic, if you will, and then you'd be able to kind of filter that whole thing out in general.

Thanks so much, Philip.

For the first time, researchers have discovered a microorganism that makes metal-organic frameworks, or MOFs.

Cable bacteria are filamentous microorganisms that can move electrons over distances of several centimetres.

It may not sound very far, but in reality this distance is about 10,000 times the width of the bacteria itself.

Facilitating this transportation are naturally biosynthesized nickel organic frameworks.

It's the first example of naturally synthesized MOFs known to us, and these MOFs conduct electricity with a similar efficiency to some of the best synthetic polymers and MOFs currently used.

How did we discover them, and can we learn something from this structure? So Pat, give us some context here.

How did the researchers come across this discovery in the first place? I mean, did we always know that this was out there or was this an accidental discovery?

Like October 21 materials from National Taiwan University and Omar Yagi's team detailed how they're combining AI and automated experiments to design porous materials.

The MOFs and COFs.

Right, which stand for metal organic frameworks and covalent organic frameworks.

And these are essentially custom designed molecular sponges used for carbon capture and water harvesting.

Furthermore, an autonomous platform optimizing a small-scale reaction does not guarantee that the process can just seamlessly scale to mass production.

Right.

And the long-term adsorption performance of those MOFs still requires rigorous subsequent verification.

So the infrastructure has to be flawless for the AI to work.

And we found a British invention.

Actually, part of that British invention is called Metal Organic Framework.

Metal Organic Framework was actually founded in the 1970s by three founders.

One of the founders is from Yorkshire.

And that founder got a Nobel Prize last year for metal organic firmware design.

And finally, the modification of the membrane properties themselves is still done by using of different polymers.

It was one presentation about MOFs, so metal organic compounds, the combination of metal surfaces or compounds and organic substances.

And another presentation was from the company using different electrolytes.

Also very interesting, they were able to customize the membrane properties just specifically for specific application.

Amorphous metal organic frameworks, or MOFs for short, are attracting interest as they retain useful characteristics of the crystalline material, such as porosity, while also exhibiting features typical of glassy materials, such as optical transparency.

Led by researchers from TU Dortmund University in Germany, a new method for creating these amorphous materials has been developed which enables a wider variety of MOF glasses to be produced with tunable properties.

Glasses are interesting in the first place.

So glasses have properties that are rarely found in other kinds of materials.

So, for example, we can introduce properties like porosity or redox activity, luminescence or whatever.

That was graduate student Jan-Benedikt Weiss.

phenanthroline was used as a flux and as a coordination sphere modifier for the metal centre in the MOF.

By combining the powdered MOF with phenanthroline and heating the mixture to no more than 300 degrees C before cooling to ambient temperature, several types of MOF that were previously thought to decompose rather than forming a glass were seen to create stable amorphous structures.

At Chillventa twenty twenty-six in Nuremberg, five-year-old German company Adsorbis launched its adsorption chiller, called Heat Chiller, which uses water as the refrigerant for industrial and data center cooling.

Unlike competing water-based adsorption chillers, Adsorbis is the first to employ an adsorption material called MOF, metal organic framework, which is a hybrid crystal covalent structure created by reacting organic molecules with metal ions.

Encased in a shell and tube heat exchanger, MOF rings are used to adsorb and release water vapor, generating chilled water down to six degrees Celsius, forty-three degrees Fahrenheit, at cooling capacities from ten kilowatts to three megawatts, two point eight to eight hundred fifty-three TR.

It leverages a hot water heat source to cause the MOF to release its water vapor.

Since it does not use compressors, the heat chiller requires up to eighty percent less electricity annually than a compressor-based chiller, and can reduce the electrical peak load by around half, according to Adsorbis.

Adsorption technology is not new, but what we are doing is completely new because we have a new material, MOF, said Hendrik Gillert, Head of Sales for Adsorbis.

He spoke about the system to naturalrefrigerants.com at the company's booth at Chillventa twenty twenty-six, where a heat chiller unit with a capacity of twenty to thirty kilowatts, five point seven to eight point five TR, was on display.

Adsorbis plans to start delivery of the heat chiller in the first quarter of twenty twenty-seven, with installations at a data center and industry, said Gillert.
