Ammonia is one of the most widely produced chemicals in the world, and is used in a great many manufacturing and service industries. The conventional production technology is the Haber-Bosch process, which combines nitrogen gas (N2) and hydrogen gas (H2) in a reactor in the presence of a catalyst. This process requires high levels of temperature and pressure, resulting in substantial power consumption. Indeed, ammonia production is estimated to consume 1%–2% of the world's electricity and to account for about 3% of global carbon emissions. In pursuit of more sustainable alternatives, researchers affiliated with the Center for Development of Functional Materials (CDMF) have developed an electrochemical nitrogen reduction process using catalysts made of iron oxide and molybdenum disulfide. Because the process is electrochemical, it does not require high temperature and pressure.

Applying green chemistry principles to iron catalysis

At the Leibniz Institute for Catalysis in Rostock, Dr. Johannes Fessler has developed new methods for the synthesis of drug precursors using catalysts made of iron, manganese and cobalt. Each of these three chemical elements has the potential to replace a number of noble metals that are commonly used in organic chemistry to catalyze fine chemicals. Platinum and palladium, for example, are expensive due to their rare occurrence, their extraction is costly and they release large quantities of the greenhouse gas CO2. One of the goals of "green" chemistry is therefore to dispense with such noble metals in organometallic catalysis in the future. Johannes Fessler gained his findings as part of his dissertation, which he defended in January. He has reported on it in Chemical Science, together with his doctoral supervisor Prof Dr. Matthias Beller and his research group leader Dr. Kathrin Junge. For example, you can read how a complex active ingredient candidate based on pyrrole, a common drug precursor, is created from "simple starting materials" with the help of an acid-tolerant homogeneous iron catalyst and at room temperature.

Rate of Chemical Reactions

-- an enzyme is a catalyst

-- the rate of a chemical reaction increases when the concentration of the reactants increases, or the temperature increases, or a catalyst is present

-- a catalyst, or an enzyme, increases the rate of a chemical reaction without being altered permanently

thursday 21/04/22

today i started my morning doing chem notes in the library before class, my favorite place to work early morning. hot coffee good music and chemistry is a great combination. i basically covered reaction intermediates, catalysts and transition states/activated complex

the physics exams went not badly! the multiple choice non-calc paper had too many calculations which threw me off but the structured paper was pretty good but doing two hours of physics was definitely taxing

A #zettelkasten or commonplace provides a catalytic surface to which ideas in the “solution of life” can more easily adhere to speed their reaction with ideas you’ve already seen and collected. Once combined via linking, further thinking and writing, they can be released as novel ideas for everyone to use.

Hello! I have a mechanics question, if you can help! I don't really farm catalysts--what drops, drops and that's just how I handle it. But out of curiosity about the ones that I'm missing, how do the Strike ones ("against the most challenging opponents") drop? Are they ANY strike or only Nightfall? Everything I've searched is conflicting with no consensus. So I'm just a little confused how that works if I ever decided I wanted to try and grind for the ones I'm missing (I know it's RNG, but RNG is gonna be zero if I don't grind in the right activity lol)

It's been random for me honestly. I remember getting catalysts drop from just ordinary strikes.

Got this from just doing a normal strike for example. I remember the same with Jotunn.

I have most of the catalysts though so when a new one drops, I get it in pretty much the first few runs. But yeah, from my experience, it can be regular strikes. Not sure if there's a higher chance if you're doing harder Nightfalls or not however.

If someone knows, feel free to share!

Something I've seen surprisingly little theorizing on is... What even is a catalyst? Some of them look like what I'd expect a special magic doodad to look like, and if that was all of them, I probably wouldn't question it, but some are just a book. Which begs the question, why are some books catalysts while others aren't? Is there a process that turned those books into catalysts? Likely, since you can have them "crafted" like other weapons. Could you do it to any book? Could you do it to any object?

In an advance they consider a breakthrough in computational chemistry research, University of Wisconsin–Madison chemical engineers have developed model of how catalytic reactions work at the atomic scale. This understanding could allow engineers and chemists to develop more efficient catalysts and tune industrial processes—potentially with enormous energy savings, given that 90% of the products we encounter in our lives are produced, at least partially, via catalysis.

Catalyst materials accelerate chemical reactions without undergoing changes themselves. They are critical for refining petroleum products and for manufacturing pharmaceuticals, plastics, food additives, fertilizers, green fuels, industrial chemicals and much more.

Scientists and engineers have spent decades fine-tuning catalytic reactions—yet because it's currently impossible to directly observe those reactions at the extreme temperatures and pressures often involved in industrial-scale catalysis, they haven't known exactly what is taking place on the nano and atomic scales. This new research helps unravel that mystery with potentially major ramifications for industry.

Catalysis breakthrough yields self-cleaning wall paint that breaks down air pollutants when exposed to sunlight

Typically, beautiful white wall paint does not stay beautiful and white forever. Often, substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while—but over time, the color changes and needs to be renewed. A research team from TU Wien and the Università Politecnica delle Marche (Italy) has now succeeded in developing special titanium oxide nanoparticles that can be added to ordinary, commercially available wall paint to establish self-cleaning power: The nanoparticles are photocatalytically active, they can use sunlight not only to bind substances from the air, but also to decompose them afterwards. The wall makes the air cleaner—and cleans itself at the same time. Waste was used as the raw material for the new wall paint: metal scrap, which would otherwise have to be discarded, and dried fallen leaves. The study is published in ACS Catalysis.

Gauthic Times #65 News & Other Stuff from Bill Gauthier, or Total Eclipse of my Art

Hello, friends! The first week of April is done and here we are. Last week was the longest year ever! So much going on at work that I barely have time to think. Writing was slow this week, which I’ll talk about. I don’t have many thoughts to go into my intro this week so I guess we’ll get right into it. Welcome to the 65th installment of Gauthic Times, the newsletter about my writing, my life,…
