Could washing our clothes with detergent become a thing of the

by Malm University
January 6, 2022

Could washing our clothes with detergent become a thing of the
past? Even though the research is in its early stages, an
investigation as to whether washing or cleaning can be done with
purified water instead of detergent solution looks promising.

"Our goal is to develop a scientific model that explains what
happens both chemically and physically when dirt is removed in
purified water. When it comes to washing with detergents we
already know what happens, but this is an unexplored area," says
Andriani Tsompou, Ph.D. candidate at Malm University.

Professor Vitaly Kocherbitov adds, "In the long run, our research
can solve environmental problems with water pollution caused by
detergents. To succeed in this, we need to better understand the
intermolecular forces that act in purified water."

The hypothesis is that in purified waterwater that has been
filtered and deionised so that impurities and especially ions are
removedrepulsive forces between charged objects become stronger.
As a result, dirt particles easier detach from surfaces and form
a finely dispersed colloidal system in water.

Tsompou explains, "When you have salt in the system, the dirt you
want to remove will clump together more and make it harder for
the water to remove the particles from the material."

According to earlier results of a study published in the Journal
of Colloid and Interface Science, Tsompou and her colleagues used
water with different properties: tap water, water with added
salt, and two grades of purified water. In a QCM-D measurementa
surface-sensitive real-time technique for analyzing surface
interaction and layer properties in thin filmsa 90% purification
of Vaseline on a glass slide was achieved for both grades of
purified water at 25-degres.

In later trials, they have been experimenting with several
washing cycles and with different temperatures and achieved a
degree of purification of 100% in purified water at 40 degrees in
two washing cycles.

In these trials, however, the most favorable conditions have been
assumed by choosing surfaces and dirts that form weak bonds. "We
have used water-friendly surfaces such as glass and silicate
which have a negative charges and then olive oil or Vaseline,
which also can get negative charges, so that they release each
other easily, explains Tsompou.

The idea is to gradually increase the bond strength and change
the materials so that they finally approach real conditions.

"Because these are such complicated processes, we have to build
up knowledge from less complicated areas. The next step will be
oil on plastic which stronger attach to each other. The end goal
is of course to test on real fabric," says Tsompou.

From Deutsche Welle:

How ancient Rome's concrete recipe can help lower emissions

Fred Schwaller
January 6, 2023

Self-healing concrete was the foundation of ancient Rome's
architectural legacy. A new study shows how to use the
wonder material to create more sustainable concrete today.

In Virgil's "Aeneid," a Latin epic poem, the god Jupiter
prophesizes that Aeneas, a hero who fled the fall of Troy, will
receive the gift of an empire that will never end. That empire
was Rome. 

The idea of creating this legacy of an everlasting empire was of
profound importance to Rome, never more so than with its great
building projects.

"The idea of setting up a memory is really important for ancient
Rome it was central to its power. Buildings like arches and
temples were perhaps the most important visible memories the
emperors and generals created. They cemented their legacy in
history," Hannah Platts, a historian at Royal Holloway University
of London, told DW.

Roman concrete was at the heart of this legacy, both literally
and symbolically the foundation of Rome's power. And while Roman
buildings are most famous for their mosaics and marble, it's with
humble concrete where the genius really lies.

Concrete started an architectural boom

Roman concrete is durable stuff. Where modern concrete types
crack and crumble in a few decades, Roman concrete has held
palaces, bridges and temples in place for millennia. The material
is why buildings like the Colosseum still stand today.

Romans were experimenting with concrete for centuries, but it was
in the first century BCE when things really took off.

"It was a time of innovation in mortars and concrete," said Riley
Snyder, a civil engineer at the University of Edinburgh, in the
United Kingdom. "They knew adding broken ceramics would create
resistance against seismic activity, or volcanic ash to make more
durable cement."

This technology revolutionized architecture. With strong
concrete, architects could build bigger and more elaborate

"Roman concrete made vaulting and domes possible, which changed
architecture forever. The massive vaults around the Colosseum,
for example, were made with poured concrete," Snyder said.

But the genius use of concrete is perhaps best exemplified in the
dome of the Pantheon, a temple in Rome built between 113-126 CE.

"The architects knew that, in order to build a dome this big,
they needed to use a heavier aggregate at the bottom of the dome
and a lighter aggregate at the top so the dome gets lighter as
you go up," Platts said. "All this helped Rome to display their

Self-healing Roman concrete

Why is Roman concrete more durable than modern concrete? Admir
Masic, a civil engineer at the Massachusetts Institute of
Technology in the United States, told DW that it comes down to
the use of volcanic ash sourced from Mounts Vesuvius or Etna.

"Romans added volcanic ash into the cement mixture," Masic said.
"It created an extraordinary material that can self-heal after
cracking. You can even crack a piece of concrete in half, and the
concrete heals after two weeks when you add water."

The self-healing properties are particularly effective in
seawater. This helped Romans build sturdy seaports and underwater
port facilities around the Mediterranean, like the one at
Caesarea in modern-day Israel.

A lost cement recipe rediscovered?

So why don't we use Roman concrete today? Unfortunately, the
recipe for self-healing concrete was lost throughout the ages,
and it is unclear when exactly its use as a building material

Scientists such as Masic have been studying samples of Roman
concrete and cement to understand why this material is so strong.

Masic's new study, published Friday in the journal Science
Advances, suggests that the way concrete was mixed could be a
clue to the material's strength.

"Our research shows that Romans used a process called 'hot
mixing' of quicklime, volcanic ash and water," Masic said.

This process of hot mixing creates so called lime clasts, which
were ubiquitous mineral components in Roman concrete.

"Originally people thought the clasts were due to bad mixing, but
I doubted this because Romans were so particular about how to
make concrete," he said.

In fact, Masic's study showed that hot mixing and lime clasts
were crucial for the self-healing properties of the material,
generating a chemical reaction with water to reforge the cracks.

More environmentally sound concrete?

Masic hopes his research will help the construction industry
create stronger and more sustainable self-healing concrete.

"Self-healing concrete is very durable, meaning less concrete
needs to be made or repaired. As such, you have a lower demand to
produce more concrete, reducing energy use," he said.

Modern concrete production is responsible for 8% of the world's
carbon dioxide emissions. With everything from roads, houses and
skyscrapers needing concrete in their construction, Masic thinks
the potential of his discovery is huge.

"We're dealing with the most widely used material in the world
here, and one with a very high carbon dioxide footprint. Reducing
the emissions in the concrete manufacturing industry could be
huge," he said.
