For chem people: This is only 25 μM. Crazy. For all people: the photo really doesn’t do the color justice. Definitely the prettiest solution I’ve ever made in #APchem #chemistry #pretty #science #nofilter @akn1128

Found this in some old papers of mine. It’s a fun little exercise you can try using some graph paper and a ruler.

Easy, looks cool, and gives a bit of insight into tangents.

biological-chemistry:

The rate of reaction increases with the temperature. However extreme temperature denatures the tertiary structure of the enzyme. Starting at zero human enzymes show increasing temperature, reaching an optimum activity at around 37 temperatures after which they denature. Destroying the proteins active sites.

Sieving silica sieves from biomass ash

Burning biomass for heat and power could produce as much as 2000 TWh by 2020, which would produce 4–15.6 million tonnes of waste ash, per year, in Europe alone. To address the problem of what to do with all this waste, scientists in the UK have developed a method to convert this ash into mesoporous silica.

Wow, I hate TV.
But this video is pretty good, it gets reasonably sciency half way through.

“Atoms aren’t just small: they’re really really small.
10^23 is an astonishingly large number. The number of grains of sand in all the beaches in the world is around 10^18. The number of stars in our galaxy is about 10^11. The number of stars in the entire visible Universe is probably around 10^22. And yet the
number of water molecules in a cup of tea is more than 10^23.”

Catalyst Preserves Fresh Fruit

Ripening fruit, vegetables and flowers release ethylene, which works as a plant hormone. Ethylene accelerates ripening, so other unripened fruit also begins to ripen — fruit and vegetables quickly spoil and flowers wilt. In the journal Angewandte Chemie, Japanese researchers have now introduced a new catalytic system for the fast and complete degradation of ethylene. This system could keep the air in warehouses ethylene-free, keeping perishable products fresh longer.

Researchers Create Stable ‘Trophy Molecule’

The search for cleaner, low temperature nuclear fuels has produced a shock result for a team of experts at The Univ. of Nottingham.

First they created a stable version of a “trophy molecule” that has eluded scientists for decades. Now they have discovered that the bonding within this molecule is far different than expected. Remarkably their findings have shown that it behaves in much the same way as its counterparts in the well-known transitional metals such as chromium, molybdenum and tungsten.

sublimatus:

Here is a very strange reaction that yields elemental, metallic potassium.

75 mL of mineral oil, 7.0 grams of KOH, 3.5 grams of Mg filed by hand from a rod of magnesium, 0.8 mL of t-butyl alcohol as a catalyst, and 200 °C for a few hours.

Let’s hope it works. :x

Krypton was stumbled upon while searching for another noble gas. The stumblers (or stumblrs, imo), Sir William Ramsay and his assistant, Morris W. Travers (Scottish and English fellows, respectively) were looking for the noble gas lighter than Argon but instead first found the noble gas heavier than it.

Taking liquified air, they removed the main components and were left with some unknown substance. They looked at the spectra of it and found it to be something they’d not seen before. Because the substance had ‘remained hidden’ in the liquified air they named it Krypton, from the Greek kryptos, meaning ‘hidden’ (cf. ‘cryptic’).
