from the entropy-is-a-bitch dept.

Knacker T Arthurbracket has found the following story:

Today's wintry tale of how the highest tech can be brought down by the simplest things comes from "Dino", for that is not his name, and takes us back to the 1990s.

Dino had been working for an outfit that provided networking over satellite. "Things," he said, "had been going well for the 12 months since the ground station was put online."

There had been no incidents or outages "other than a couple of solar flares interrupting things".

It was all too good to last: "One December evening I got a call from the on-shift engineer saying that no matter what he did, the test signal we were monitoring back to ourselves kept falling."

This wasn't good, and was a sign that the dish had probably got off-track with the satellite. If not corrected, the resultant loss of service would be both inconvenient and expensive for those footing the bill for that out-of-this-world networking. Dealing with the problem, Dino told us, meant that "some very careful repointing may have to take place manually".

Obviously it wasn't ideal, but being the dedicated professional that he is (and because the facility wasn't far), Dino "got in the car and shot down to the ground station, whereupon I was greeted by a rather frantic engineer".

The panicked techie led Dino to the ops room, showed him the falling signal and, no doubt in that high-pitched wavering voice many adopt in moments of stress, "explained that he didn't know what else to do".

Dino peered around the brightly lit operations room, with all its machinery, flashing lights, machines that go "ping", and windows (of the glass variety).

At that point the penny dropped. With all the lights on, it was impossible to see outside into the night. And outside it was "yup... snowing."

The duo trotted out in the winter night and found the dish covered in the fluffy white stuff.

"The dish heaters had tripped and the dish was covered in snow, so it was obvious why we had a falling signal..."

Hurrah! No manual repointing was needed, just the low-tech judicious application of a broom to brush the stuff off and turning the heaters back on.

Job done! The two headed back into the warmth of the ops room for a well-earned coffee.

"Only," said Dino, "it wasn't high-five time just yet."

Title: Americium In A Mof

Americium is a by-product in nuclear reactors that continues to emit radiation for thousands of years. Its separation from spent nuclear fuels has therefore motivated copious study of its fundamental coordination chemistry. To this end, Cahill et al. have now incorporated trivalent 243Am ions into a metal-organic framework (MOF). The framework architecture was chosen on the basis of known analogs prepared from chemically similar but more stable lanthanide ions. Although radioactive decay progressively damaged the crystals, the authors were still able to refine structural data over the course of 3 months.
