Scientists make "Impossible Material" ... by accident

In an effort to create a more viable material for drug delivery, a team of researchers has accidentally created an entirely new material thought for more than 100 years to be impossible to make. Upsalite is a new form of non-toxic magnesium carbonate with an extremely porous surface area which allows it to absorb more moisture at low humidities than any other known material. "The total area of the pore walls of one gram of material would cover 800 square meters (8611 sq ft) if you would 'roll them out'", Maria Strømme, Professor of Nanotechnology at the Uppsala University, Sweden tells Gizmag. That's roughly equal to the sail area of a megayacht. Aside from using substantially less energy to create drier environments for producing electronics, batteries and pharmaceuticals, Upsalite could also be used to clean up oil spills, toxic waste and residues.

Scientists have long puzzled over this particular form of magnesium carbonate since it doesn't normally occur in nature and has defied synthesis in laboratories. Until now, its properties have remained a mystery. Strømme confesses that they didn't actually set out to create it. "We were really into making a porous calcium carbonate for drug delivery purposes and wanted to try to make a similarly porous magnesium carbonate since we knew that magnesium carbonate was non-toxic and already approved for drug delivery," she tells us. "We tried to use the same process as with the calcium carbonate, totally unaware of the fact that researchers had tried to make disordered magnesium carbonates for many decades using this route without succeeding."

The breakthrough came when they tweaked the process a little and accidentally left the material in the reaction chamber over a weekend. On their return they found a new gel in place. "We realized that the material we had made was one that had been claimed impossible to make," Strømme adds. A year spent refining the process gave them Upsalite.

While creating a theoretical material sounds like cause for celebration, Strømme says the major scientific breakthrough is to be found in its amazing properties. No other known carbonate has a surface area as large as 800 sq m per gram. Though scientists have created many new high surface area materials with nanotechnology, such as carbon nanotubes and zeolites, what makes Upsalite special is the minuteness of its nanopores.

Each nanopore is less than 10 nanometers in diameter which results in one gram of the material having a whopping 26 trillion nanopores. "If a material has many small pores," explains Strømme, "it gives the material a very large surface area per gram, which gives the material many reaction sites, i.e. sites that can react with the environment, with specific chemicals, or in the case of Upsalite, with moisture."

Upsalite's moisture absorption properties are striking. It was found to absorb 20 times more moisture than fumed silica, a material used for cat box fillers and as an anti-caking agent for moisture control during the transport of moisture sensitive goods. This means that you'd need 20 times less material to do the moisture control job.

Its unique pore structure also opens up new applications in drug delivery. The pores can host drugs that need protection from the environment before being delivered to the human body. It's also useful in thermal insulation, drying residues from oil and gas industries, and as a dessicant for humidity control. Potential applications are still being discovered as the material undergoes development for industrial use.

The team at Uppsala University is commercializing Upsalite through their spin-off company Disruptive Materials. An article describing the material and its properties can be found at PLOS ONE.

It's amazing how many times important discoveries have been made by accident!

Joel Detrow

Some of the biggest discoveries have come from failed experiments.

In 1856, William Henry Perkin, 18 years old, was challenged by his professor to come up with a way to synthesize quinine for treating malaria.

While cleaning the glassware with alcohol after a failure, he noticed it turned a brilliant shade of purple. Having kept notes of the process he was able to duplicate the result, launching the synthetic color industry with 3-amino-2,±9-dimethyl-5-phenyl-7-(p-tolylamino)phenazinium acetate.

I'm with Andrew - this material will almost overnight revolutionise the tampon and lady-pad industry! As an 'older' man (think prostate) it would also be ideal for us, easily made into a concealable liner for jocks or boxer shorts. More power to the 'accidental genius'!

The Skud

Scientific progress goes "boink". :-)

Finally, an area comparison we can all relate to - the sails on our megayachts! It is nice to have a break from all those supercar articles, too. Who needs more than half a dozen ?

Bob Stuart

I just hope that the kitty litter filler is produced from used drug delivery material, rather than the other way around.


Should make a effective water filter as well.


Will I be able to get rid on my not-so-user-friendly dehumidifier down in the basement? Will they make a 'brick' of this miracle for me to use instead?


Can it be used to store heat or hydrogen? I would like to store the heat of summer to be used in winter and the reverse cheaply.


I wonder if it would be possible to use this material to fill a hydrogen fuel tank so it can hold in increased amounts of hydrogen gas. If so, the automotive industry might be very excited about this material ! There is a similar material made from heated feathers that is able to hold large amounts hydrogen gas.


I wonder if it can be used in low pressure absorption storage for the natural gas industry. To date I think the best nano-structured carbon absorbent material was carbonized corn cobs. I don't know what the nano pore count is of that material but if magnesium carbonate surpasses it then even higher density, medium pressure tanks for transportation and gas recovery could be huge winners.

Jim Friedl

doug, you can view absorbency as a phase tradition from an energy use and storage standpoint - so you could use this as part of an energy cycle. I doubt it will have energy storage characteristics worth noting, though it could have interesting capacitive properties if it is at all conductive (or be a good substrate for vapor deposition ultra-capacitors).

Charles Bosse

it may enhance solar power systems.


Amazing! There are SO many applications for something like this. And there has to be a way to use this to make more complex multi-layered computer chips.

And sorry to go here, but that scientist Maria Strømme is smoking hot! Brilliant AND beautiful. She's like the perfect woman.


If I remember correctly, fly ash and silica fume do their job making high strength concrete because they're small particles with a very large surface area. I also recall needing to keep concrete damp for a couple weeks after pouring it to help it cure properly. I wonder about Upsalite as a concrete admixture.

John Banister

I'm surprised no one mentioned of the most obvious and possibly revolutionary uses for such a porous material.

How about increased energy storage for much more powerful and much faster charging batteries?

With this can it finally be that electric cars of the near future, might charge up as fast as a gas pump could fill the tank of a gas powered car?

If I were the head of Tesla Motors, I would be experimenting with this as soon as I could possibly get some of it.


What a great name! short for Upsala salt lite.

Henry Van Campa

I'm waiting for the other shoe to drop. What is the downside of this wondrous, accidentally-created material? What keeps it from forming naturally on the earth since it's made from earthbound elements?

Instead of looking for new drug delivery methods, why not hip people to the healing, life-preserving effects of simply eating fresh, whole raw foods? If you want to live, stop eating things that are DEAD!!

Kim Armstead

So I guess this means they failed at creating the material they needed for more efficient drug delivery.

Derrick Mains


Congratulation for this wonderful material. I am an architect. I want to know about thermal properties of this wonderful material. You said that it will be used as an insulation.

How much energy to get the moisture back out. if it is low enough it might make Swamp Coolers practical even in humid environments.

re; Durhamhs Even without the storage issues hydrogen is lousy fuel.


As much as I see a place for structured science I still think we need a department dedicated to scientists just fucking around. The number of supposedly impossible things that have been created completely by going against the protocol leads me to believe a fucking around department could in fact accelerate science to a whole new level!
