Solar Orbiter probe snaps the sharpest ever image of the Sun's
corona

Nick Lavars
March 24, 2022

Since launching in February of 2020, the Solar Orbiter probe has
been zeroing in on the Sun with a suite of instruments designed
to unravel some of its secrets. Among those is an advanced
ultraviolet imager, which mission control has now used to capture
the highest-resolution image ever of the Sun's outer atmosphere.

The incredibly detailed new image was captured by the Extreme
Ultraviolet Imager aboard NASA and the ESA's Solar Orbiter, which
shoots at the wavelength required to image the Sun's outer
atmosphere, or corona, where temperatures sit at around one
million °C (1.8 million °F).

The spacecraft was around 75 million km (46 million miles) away
from the Sun on March 7 when it captured this sharp new view,
taking 25 individual images over the course of four hours to
create the final mosaic. This resulting image features more than
83 million pixels in a 9,148 x 9,112 pixel grid, which is a
resolution around 10 times that of a 4K TV.

At the same time, the probe's Spectral Imaging of the Coronal
Environment (SPICE) instrument was used to image the Sun in the
wavelength of ultraviolet light emitted by different atoms. This
enables it to peer beneath the corona and take the Sun's
temperature at a layer known as the chromosphere.

The purple depicts hydrogen gas at 10,000°C, blue depicts carbon
at 32,000°C, green depicts oxygen at 320,000°C, and yellow
depicts neon at 630,000°C. These kinds of insights will help
scientists understand how temperature rises through the
atmospheric layers of the Sun, which counterintuitively is much
higher at the corona than it is at the surface (around 5,000 °C).

Team takes key step toward truly recycling plastic

Researchers have successfully broken plastic into its
molecular building blocks and recovered over 90% of them.

Posted by Peter Rüegg
March 28th, 2022

It's a first step towards genuine plastic recycling.

The chemical industry has a long tradition of producing polymers.
This involves turning small molecular building blocks into long
chains of molecules that bond together. Polymers are the basis of
all kinds of everyday plastics, such as PET and polyurethane.

However, while the formation of polymers is well established and
well researched, scientists have given little attention to how
polymer chains are broken down (a process called
depolymerization) to recover their individual building blocks,
called monomers.

Breaking down polymers is a complex process. Whether a polymer
can be broken back down at all into its constituent parts depends
on which of the different polymer manufacturing processes created
it. In addition, the depolymerization processes used so far
require a lot of energy, which has made them too expensive. And,
recycled polymers are usually only used to make low-value
products.

Athina Anastasaki, professor of polymeric materials at ETH
Zurich, wants to change this. Her goal is producing polymers that
can be easily broken down into their building blocks so that they
can be fully recycled.

Anastasaki has taken a first step in this direction: A study by
her group appears in the Journal of the American Chemical
Society. In it, Anastasaki and her colleagues show that they can
break down certain polymers into their basic building
blocks—monomers—and recycle them for use in materials for further
applications.

The polymers broken down are polymethacrylates (e.g. Plexiglass)
that were produced using a specific polymerization technique
called reversible addition-fragmentation chain-transfer
polymerization, otherwise known as RAFT. This relatively new
method, which is now also attracting the interest of industry,
produces polymer chains of uniform length.

The researchers have succeeded in recovering up to 92% of the
building blocks of polymethacrylates without adding a catalyst
that would enable or accelerate the reaction.

"Our method could conceivably be developed even further to
involve the use of a catalyst. This could increase the amount
recovered even more," says Anastasaki.

The chemical group present at the end of a polymer chain is
crucial for the polymer's breakdown. By heating the polymer
solvent mixture to 120°C, the researchers created what are
referred to as "radicals" at the end of a polymethacrylate chain,
which triggered the depolymerization. Researchers at the
Australian National University in Canberra confirmed the results
mathematically.

According to Anastasaki, the building blocks recovered in this
way can produce the same polymer or a completely different
product—an insoluble hydrogel that can also be broken down into
its monomers. The newly created products are of similar quality
to the original ones. This is in contrast to previous products
made from recycled polymers.

But there is a catch: "Products made with RAFT polymerization are
more expensive than conventional polymers," says Anastasaki. To
address this drawback, she and her group are working to expand
the method for large-scale use, which will make it more
competitive and the resulting products cheaper. The researchers
also aim to increase the amount retrieved and to recover all the
building blocks of a polymer.

Anastasaki is also researching whether other polymers can be
depolymerized. She is particularly interested in polystyrene, a
widespread, low-cost plastic that has many everyday uses, such as
Styrofoam.

Even if this new method raises hopes of solving humankind's
plastic waste problem, Anastasaki dismisses the idea for the time
being. There is no quick fix to the problem. "It will take a lot
of time and research before the process is established in the
chemical industry," she says. Nor will the method get rid of
plastic waste: today's polymers cannot be broken down in this
way. Some new, suitable polymers have to come into circulation
before their building blocks can be recovered. But the method has
one advantage: its introduction and use require no new chemical
plants.

"We are only at the beginning of our research into
depolymerization. There are over 30,000 studies on developing new
polymerization strategies, with only a handful of them addressing
the subject of monomer recovery," says Anastasaki.
