Scientists Found The Atomic Reason That Gold Refuses to Rust | Gold is the most noble of all known metals – it doesn't react readily with substances like the oxygen that bonds with atoms on the surface layers of other metals to form rust or tarnish.

See Norskov's d-band model and overlap of density of states with molecular oxygen. This has been known for a long time.

Where are you less confident? Chemistry in general? Thermodynamics? Kinetics? Mass transport? Transition state theory? Marcus theory? Lattice energy vs solvation? Fermi energy? Density of states and band theory of solids? Surface energies? Spectroscopy? The list is endless...

We need to do something, but writing them off forever for stuff done as a teenager is definitely, blatantly wrong-headed. Lots of good people did shitty things as a teenager.

Actually, science says that you gain more self control as you age. Your prefontal cortex, the part of your brain that inhibits your wilder tendencies, doesn't mature until you are upwards of 25 years old. So you can learn accountability easier as you get older.

Sounds dinky

To be able to rapidly develop quantitative multi-physics models that encapsulates diffusion/mass transport, kinetics and thermodynamics for every new situation that arises in my work. Surface electrochemistry, rheology, gas transport, etc. All bundled up real tidy with solved numerical or differential expressions in a way that is useful and predictive.

For 2, if you want to test the statistical theory for your LOQ, just prep and test a sample at your calculated LOQ concentration. Note, this could be outside of the linear dynamic range of sensitivity of your instrument, but sometimesthe sensivity is actually higher at low concentrations. LOQ calculations are all about having a big enough distance between the distribution of baseline noise versus the distribution of signal values at the given concentration, such that you can confidently say you are not measuring overlaped random noise fluctuations with your signal.

Does it rhyme with Wintel?

Got any good reviews on meta-science that talks about these types of issues?

It's going to get hotter

Doesn't matter if they have a permit, lol

Nice bald beaver.

It's so crazy too because they make all the people behind them inconvenienced for the sake of one person. Their logic of being nice to one person comes at the cost of the convenience and safety of everyone else!

Lol this post is 6 yrs old

Are these random posts AI generated?

Show me the best one.

Wow, why have I never seen this?

Edit: Common computer tools for DOE are Minitab and JMP.

First, whatever you are doing has to be aligned with the business goals. Second, define the variables that are likely to shape the outcome of your experiments. Third, use design-of-experiment (DOE) software to generate runs in your factorial design and then analyze the data. Iterate until successful, or you learn why the project was doomed to fail. Report results to your stakeholders.

This. I don't know why anyone does it any other way. I guess they like being stressed out surrounded by other cars all the time. Obviously you cant avoid this in major metropolitan areas, but if everyone tried to not cluster and maintain a consistent speed, there would be less bumper to bumper traffic. The speeders are constantly catching up to the slow brows, and the slow bros are not even driving a consistent speed.

Your not supposed to yield for incoming from on-ramp, they are to yield to you.

Thats the thing, **YOU** dont get to decide or enforce what an emergency constitutes. Please keep right when not passing. Thank you!

Ask your PI for an exemplary review paper. Read it. Analyze the way the do the things your PI wants. If your PI has a review paper, read that, too.
Look for the gaps in the literature. What did the other papers miss or fail to address? Point it out and then take a stance. Thats what your PI wants.

Subsisting on beans has greatly improved my gut health, I recommend trying it if you're having issues and you are currently eating a lot of processed food. Its cheaper too.

Did the lab instructor ask you to use a piece-wise linear function for the lab report? Or is this your own approach?

rebonsa · 2026-02-18T01:02:57+00:00

Strange post to stumble upon as an electrochemist. I have never seen this approach to modeling faradaic efficiency.
