Yttrium is a chemical element with the symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element". Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals, and is never found in nature as a free element. 89Y is the only stable isotope, and the only isotope found in the Earth's crust. The most important uses of yttrium are LEDs and phosphors, particularly the red phosphors in television set cathode ray tube displays. Yttrium is also used in the production of electrodes, electrolytes, electronic filters, lasers, superconductors, various medical applications, and tracing various materials to enhance their properties. Yttrium has no known biological role. Exposure to yttrium compounds can cause lung disease in humans. The element is named after ytterbite, a mineral first identified in 1787 by the chemist Arrhenius. He named the mineral after the village of Ytterby, in Sweden, where it had been discovered. When one of the chemicals in ytterbite was later found to be the previously unidentified element, yttrium, the element was then named after the mineral.

Terbium is a chemical element with the symbol Tb and atomic number 65. It is a silvery-white, rare earth metal that is malleable, and ductile. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas. Terbium is never found in nature as a free element, but it is contained in many minerals, including cerite, gadolinite, monazite, xenotime and euxenite. Swedish chemist Carl Gustaf Mosander discovered terbium as a chemical element in 1843. He detected it as an impurity in yttrium oxide, Y2O3. Yttrium and terbium, as well as erbium and ytterbium, are named after the village of Ytterby in Sweden. Terbium was not isolated in pure form until the advent of ion exchange techniques. Terbium is used to dope calcium fluoride, calcium tungstate and strontium molybdate in solid-state devices, and as a crystal stabilizer of fuel cells that operate at elevated temperatures. As a component of Terfenol-D (an alloy that expands and contracts when exposed to magnetic fields more than any other alloy), terbium is of use in actuators, in naval sonar systems and in sensors. Most of the world's terbium supply is used in green phosphors. Terbium oxide is in fluorescent lamps and television and monitor cathode ray tubes (CRTs). Terbium green phosphors are combined with divalent europium blue phosphors and trivalent europium red phosphors to provide trichromatic lighting technology, a high-efficiency white light used for standard illumination in indoor lighting.

“Good morning, gentlemen,” he said, with a broad smile. (Yuck – again.) “We have a few little, shall we say, ‘games’ to play this morning,” he continued. Then he turned to Ingrid and ordered: “Doctor, shave their heads and apply the electrodes, if you would be so kind.” “Electrodes”? That didn’t sound very promising. What was left of my afro was roughly shaven – David’s hair, too. I didn’t really care much about this but David grumbled and moaned enormously. (I wondered idly whether all zombies were such whingers.) I hadn’t previously noticed that he – or any other zombie, for that matter – took any particular pride in their locks. Indeed, all the zombies that I’d met seemed to make it a badge of honour to clot their hair up with as much dried blood and congealed gore as they could. It was just the indignity of the thing, I suppose. Soon, my newly-bald head was covered with shiny, stick-on electrode pads – carefully placed on me by the tasty (?) Ingrid. The electrodes were then attached to an ancient-looking EEG (electroencephalogram) in order to measure my brain waves. Ingrid and the Captain then started to take readings from the cathode ray tube. Lots of lovely wiggly lines being traced across the screen. What did it mean? Dunno. I suppose it meant my brain was working. Beyond that? Ask someone else. They did this for a while and made a whole bunch of fairly boring and unintelligible (to me, at least) remarks. Then it was David’s turn. Same deal: carefully placed, stick-on electrodes all over his bald cranium, hook up to EEG, read out screen. Result? A screen full of flat-line tracings. Not even a faint wobble on any line. Not the slightest tremble. “This man is dead,” observed Ingrid. (What a genius!) “Hmm,” responded the Captain. (Another genius.)
