Video
Better together
Shown here are two nanoparticles with cadmium cores encased in cadmium chloride shells, growing and merging with each other over the course of about 50 seconds. The union of the particles was recorded by Qiubo Zhang, a postdoc in Haimei Zheng’s lab at Lawrence Berkeley National Laboratory, using high-resolution liquid cell transmission electron microscopy (LC-TEM). The video shows that the particles’ growth is guided by a defect in the right-hand particle’s shell, which contradicts long-held notions about how particles in solution combine through a size-driven process known as Oswald ripening.
Zheng’s group uses advanced TEM methods to look how nanoscale imperfections impact dynamic physical and chemical processes. Understanding the factors that influence nanoparticles’ growth, Zheng says, will help scientists design better materials for use in catalysis and energy storage. The team published their findings in Nature Communications earlier this year (DOI: 10.1038/s41467-022-29847-8).—Brianna Barbu

Three microscopes see more than two
One has to look very closely to understand what processes take place on the surfaces of catalysts. Solid catalysts are often finely structured materials made of tiny crystals. There are various microscopies to monitor chemical processes on such surfaces—they use, for example, ultraviolet light, X-rays or electrons. But no single method alone provides a complete picture.
This is why research teams from TU Wien and the Fritz Haber Institute in Berlin have developed a novel approach that allows to have “triple eyes” on a catalytic reaction—using three different surface microscopies. This way, they were able to show that during the catalytic conversion of hydrogen and oxygen to water, reaction fronts on the crystal surface not only form remarkable geometric patterns, but also a new mechanism of the propagation of these fronts was discovered.
For climate-relevant technologies such as ecologically clean hydrogen-based energy production, a comprehensive understanding of such processes is crucial.

Creating hydrogen storage materials from industrial waste
Whether it is cars, energy or mobile phones, modern society is built on metals, and our future strongly depends on these materials, too. To store hydrogen in a safe, compact and still environmentally friendly way is still a major challenge. Metal hydrides could be an appealing solution, especially for those applications where the volume and safety of the storage system is an issue—for example, in stationary storages, in hydrogen refueling stations or ships—as they can provide a very high storage density. High-purity metals are commonly used to produce these storage materials. Despite their advantages, the mining and large-scale production of these materials is a heavy burden on the environment as they emit large amounts of greenhouse gases, not to speak of the impact of mining of the raw materials on the landscape itself.
Researchers at the Helmholtz-Zentrum Hereon Institute of Hydrogen Technology have now shown that high-quality hydrogen storage materials can also be produced from less pure industrial metal wastes. These findings allow us for the first time to use a circular economy strategy to produce metal hydrides. As a result, their production is much more environmentally friendly.
“The utilization of circular economy approaches to the production of hydrogen storage materials allows us to tackle the energy challenges that modern times pose to our society in a more sustainable manner,” says Dr. Claudio Pistidda, scientist at the Hereon Institute of Hydrogen Technology.

Ultrathin fuel cell uses the body’s own sugar to generate electricity
Glucose is the sugar we absorb from the foods we eat. It is the fuel that powers every cell in our bodies. Could glucose also power tomorrow’s medical implants?
Engineers at MIT and the Technical University of Munich think so. They have designed a new kind of glucose fuel cell that converts glucose directly into electricity. The device is smaller than other proposed glucose fuel cells, measuring just 400 nanometers thick, or about 1/100 the diameter of a human hair. The sugary power source generates about 43 microwatts per square centimeter of electricity, achieving the highest power density of any glucose fuel cell to date under ambient conditions.
The new device is also resilient, able to withstand temperatures up to 600 degrees Celsius. If incorporated into a medical implant, the fuel cell could remain stable through the high-temperature sterilization process required for all implantable devices.
The heart of the new device is made from ceramic, a material that retains its electrochemical properties even at high temperatures and miniature scales. The researchers envision the new design could be made into ultrathin films or coatings and wrapped around implants to passively power electronics, using the body’s abundant glucose supply.

TES Science: Harrowstorms are Caused by Oxygen Radicals
Context: There is a field of chemistry called ‘Radical Chemistry’ and it is the study of free radicals. Free radicals are molecules that contain one unpaired valence electron. Cause of this radicals love to react with things.
One known radical is an Oxygen Radical, these are produced naturally but some conditions can make them appear more.
Tumblr media
So how do oxygen radicals connect to giant red storms that turn people to vampires or harrowfeinds. Well this is less how they work and more how they are created.
Things we know about Harrowstorms is:
-        There is a ritual.
-        Alchemy is involved.
-        Remains are used especially in those of the elderly.
Now despite what people say, alchemy is chemistry. Chemistry would not exist without alchemy. So, I can substitute alchemy here for Chemistry.
When it comes to actual storms, especially thunderstorms ozone (O3) is needed. It also causes that ‘pre-rain smell’.
This is the formation of Ozone:
Tumblr media
It requires oxygen radicals to form.
Now another interesting thing to note is a theory of ageing called DNA Damage Theory. In short, this theory states that physical ageing is caused by the DNA naturally damaging cells and then replacing them over time. This can partly be done by the DNA breaking down and bi-producing oxygen radicals. The body naturally produces oxygen radicals.
When organic matter has an excess amount of oxygen radicals something called Oxidative Stress happens.
Tumblr media
As shown above, this can also cause major health issues if allowed to go on. Your body naturally prevents oxidative stress with antioxidants. However, if you look at the image of the oxidised apple, and then compare it to Harrowfeinds.
Tumblr media
and you begin to see that the two sort of look similar.
Harrowfinds seem to look like there tissue has gone though oxidative stress. Because of the Haorrwstorm that requires oxygen radicals.
In sort the Harrowstorm’s cause harrowfeinds and the harrowfinds made boost the harrowstorm.
While the prosses of making a harrowstorm is labelled as the theft of life energy it could be semi science explained. Hypothetically the magic used could force aging, producing a major amount of oxygen radicals that would then, A. kill someone, or B. turn them into a harrowfeind (with the added vampire magic). This would also make storms self-sufficient as long as there where bodies around.
To add to all of this, it can be argued that the Reachmen witches fully know how this works. The evidence to support this is in their wicker masks.
Tumblr media
While these masks look cool there is actually possibly more to them. Thanks to probably data mining or ZOS, we know the Icereach coven motif is made out of a type of Willow.
Tumblr media
Now scientists have studied willow trees because they are well known for their medicinal properties however one study, I found states:
Tumblr media
Willow bark extract protects against oxidative stress. The thing that I am proposing Harrowstorms can cause.
In short, this implies if not confirms the Icereach witches have knowledge of radical chemistry. Radical chemistry was only really started in 1900 and it takes a log of pre-chemical bases to get there such as organic chemistry, chemical mechanisms, electron theory etc.
Meaning as a culture it is highly likely that the Reachmen are the most scientifically advanced in terms of practicality. Meaning they care much more about medicine, textiles, ecology, and improving quality of life than say the Dwemer’s flashy machinery and hall blades.
TLDR; The reachmen are likely the most scientifically advanced race in TES, Harrowstorms is a good blend of magic and science.
