C&EN, "Are COFs the new MOFs?"
There are many new technologies to develop for specific chemical processes or goals. Refining of lanthanides is one. New processes include electrophoresis and magnetophoresis. Finding the optimal chemistry remains to determined. Not only can this technology be used for processing elements... -
High School GRB 250702B, the longest gamma-ray burst in history
There was an X-ray 'precursor', i.e., the X-ray process began almost a day earlier than the process that caused the gamma rays as indicated by @Ibix. X-rays are formed by atomic electrons, or bremsstrahlung interactions. Gamma rays are formed in nuclear and subatomic interactions; the...- Astronuc

Today I Learned
Yes, I've seen some videos of the derailment. Pretty stunning. The locomotives stayed on the trestle. I hadn't seen that video, but I saw earlier videos when it first happened. I was curious about the cause - possibly a broken rail, a broken wheel or axle, or some shift in the gauge. The...- Astronuc

Graduate Trouble Making a Penning Ion Source
The hydrogen gas is igniting (as in combustion) or arcing? If the former, it would seem one has an air (oxygen) leak, or free F through decomposition of teflon. H + F = HF is a fairly energetic reaction. Is the Penning source a negative H- ion supply?- Astronuc
