  Tholin - Open Encyclopedia   (Site not responding. Last check: 2007-10-08)
Tholin is a heteropolymer formed by solar ultraviolet irradiation of simple organic compounds such as methane or ethane.
Tholins do not form naturally on modern-day Earth, but are found in great abundance on the surface of icy bodies in the outer solar system.
"Triton tholin" and "Titan tholin" are nitrogen-rich organic substances produced by the irradiation of gaseous mixtures of N

The tholin is thought to be very similar to the orange-red haze of the upper atmosphere of Titan.
The four solid curves are for different assumed particle sizes of Titan tholin in the haze layer, ranging from 0.1 micrometers to 1 micrometer.
Tholin seems to be a major constituent of the observed haze, and thus we can make some claim to have bottled the clouds of Titan.

Rookie Line-X Modified driver Mike Tholin, who has one of the new Champlain Valley Racing Association Jasper crate engines under the hood of his car, was turning 358 modified times as drivers got their first chance to hit the speedway in 2004.
Tholin was one of the most impressive drivers, lending credence to the Jasper engine racing program.
Tholin, who was the 2003 hobby stock champion at Albany-Saratoga Speedway, opted to go with the Jasper engine program after blowing a regular sportsman motor at another warmup session earlier in the month.

 Tholin Baths
On their icy worlds the Muuh have constructed spa-like structures that utilize liquid methane containing the complex organic molecules collectively known as tholins.
Tholins form a sludge that is brownish-red to human eyes, and though in time they settle out of a methane solution they can be kept in a soup-like suspension under certain conditions.
Natural tholin spas are highly valued on Muuhome, and artificial equivalents are considered an essential element in Muuh living quarters.

 Astrobiology: The Living Universe - Life
One of these building blocks in particular is tholin, a mixture of complex organic molecules composed of carbon, nitrogen, oxygen and nitrogen.
Tholin is an extremely interesting molecule - while it does not exist on Earth since it would simply burn away in our oxygen-rich atmosphere, many scientists believe that it may have existed in the past on Earth, and could exist on the cold outer solar system planets - such as Titan.
Tholin can be made very easily from a mixture methane, ammonia and water vapour by lightening discharges; these are all very common chemicals and occurrences on planets such as Titan.

 tholin
Tholins don't exist naturally on Earth, because our present oxidizing atmosphere blocks their synthesis.
However, tholins can be made in the lab by subjecting mixtures of methane, ammonia, and water vapor to simulated lightning discharges.
The presence of tholins may help explain the orange-red hue of Titan's atmosphere and the reddish surface of some Centaurs and outer asteroids.

Tholin is a sticky, waxy, dark red residue whose tiny particles cause the brownish haze of Saturn's largest moon, Titan.
The tholin that may cover Phoebe is thought by Cruikshank and others to be abiotic, which means it is not made from living organisms.
Scientists hypothesize the tholin is a natural by-product of the organic chemistry of the carbonaceous materials that make up Phoebe.

Tholin was a Taran whose name would be best known in his home clan, only that his name is old and many like to claim kinship with him.
It is of course not believed that Tholin could actually smell such things as gold.
Summary: Tholin, whose old name can no longer be connected firmly to any clan (and some suspect that he is but fantasy, and never could be connected properly), claimed (and seemed) to have a nose for finding rich veins of silver, gold, iron or anything else of value.

 Unmanned Spaceflight.com -> Any Tholin At Huygens Landing Site?
Is there any indication of tholin or oganic goo at the Huygens landing site or was it believed to be washed away by the methane rain?
Not usre what it is but presumably it is some kind of tholin or higher order hydrocarbon residue left before after the methane evaporates or drains down into the soil.
That you can count on -- very complex compounds have turned up in the ACP pyrolysis of cloud particles, and some organics heavier than methane were also volatilized out of the surface after landing by the GCMS' heated inlet (which was heated to fully 90 deg C).

The current rate structure ensures that customers pay higher-than-market rates during most of the day and provides no incentive for persons to reduce their electricity use during peak demand times, according to Tholin.
ESPP participants receive special notices if prices are expected to exceed 10 cents a kilowatt hour (the flat rate this summer is 8.28 cents), giving them the chance to shut off appliances, raise the thermostat on their air conditioner or take other measures to reduce consumption, if they choose.
Tholin said the information gleaned from the ESPP experience could be used to work for de-regulation of the electric industry in Illinois.

It is intended to bridge the gap between existing gas phase chemical network models that predict mixing ratios as a function of altitude and physical models that predict albedo and other physical properties of Titan haze.
The rudimentary initial model for Titan tholin growth focuses on the addition of ethynyl radicals to several possible nuclei, including linear polyynes and cyclic aromatic hydrocarbons such as benzene.
The model utilizes a rule set that describes outcomes for an extended sequence of collisions between a test particle and ethynyl radicals.
