I say no. First of all, your going to have to get your food awfully hot to render it organism free. Also the air in there is not organism free. Nor is the container itself. Perhaps if you sterilize the container as well and do it in a clean room. Or you could get a whole bunch of smoke detectors, break them open, pull out the americium and use that as a gamma radiation source and sterilize the whole thing with that. I have scalpel blades gamma radiation sterilized. Or you could get a short wave (germicidal) UV lamp, though you might need to mash the food for that. Then again you could probably just get one of the little vacuum sealers, it would probably be simpler. chemkid PS Please don't try the smoke detector one, its illegal and you'll end up on the evening news

Nope, only ethanol will work. Or at least isopropanol won't work. It doesn't burn hot enough and often goes out on it's own. Won't ruin anything using isoprpanol so feel free to try it out. Denatured ethanol will work fine as well. Just doesn't work. Ask me how i know: weeks of frustration, i spent so long trying to get a damn alcohol burner to work!!! Didn't realize that isopropyl alcohol wouldn't work. chemkid

If you were to provide oxygen to a fuel source and warm said oxygen you may be able to sustain a reaction at very small size. It would be interesting making a campfire under a microscope using threads of cotton! fuel will be a major problem. Fuel most be provided very fast as very small things burn very qucikly. Chemkid

Satellite imagery of the great Pacific garbage patch?
chemkid replied to chemkid's topic in Ecology and the Environment
I have tried google earth. They don't have actual pictures of the ocean. I have searched the internet as well. -
I have checked several imagery providers none of which seem to to provide imagery of the ocean where on may find a picture of this colossal floating garbage patch. I would quite like to be able to examine this phenomena. If any one has been able to find it, or may know a provider which has such imagery please inform me. Chemkid

United Nucleous? Your site looks suspiciously similar to United Nuclear, i doubt United Nuclear will appreciate that

Problems with the fossil record
chemkid replied to idiotseven's topic in Evolution, Morphology and Exobiology
wow, the missing link argument is extremely poor. EXISTANCE IS DISCRETE. Even if we had a fossil of every single creature that was ever to exist, one could still say - look there is a gap between the parent and it's child. When did that gene mutate? Look there's a gap between parent and child. We can never have on continuous line of evolution. I doubt we will ever get close. Then again, paleontology is not about making continuous lines of evolution, but taking what we have and putting it together. Chemkid -
Problems with the fossil record
chemkid replied to idiotseven's topic in Evolution, Morphology and Exobiology
True fossils may be rare to form. But keep in mind there are lots and lots of animals to be fossilized. While the shreaded piece of paper example is good, we need a gigantic sheet of paper (to reprsent the gigantic bioshpere which exists) making 10% stil be a good amount of paper. Despite having no record of 90% of life on earth millions of years ago, 10% is still a tremendous amount of data. Chemkid -
Perhaps if one worked on the roman arch concept except made it into a sphere? But casting all those tiny wedges perfectly would sure be a pain.

Well if we are bubbling through aqueous (of course) hydrogen peroxide the acid would immediately be dissolve (right?) Chemkid

A process called hypereutrohphication could perhaps occur, with devastating affects. The increased sunlight would increase algae and bacteria growth in ponds as would a large amount of nitrates and phosphates in the water. This is called an algae bloom. Then the algae would die eventually. There death and decay would suck the dissolved oxygen out of the water and suffocate all the oxygen dependent organisms in the lake. If this process where to continue i would think it would render most water bodies lifeless except for extremophiles. Chemkid

What would you like to burn a substance in is also a factor. For example, many things will burn in elemental flourine however very few will burn in nitrogen. Also, 'fire' isn't easily defined, perhpas oxidation (if you want to burn things in oxygen) Another factor is how much of a material you are burning. As stated before, what temperature are you looking at? Auto ignition point? In what percent oxygen? If you want to use autoignition point what form of the substance are you using? Powdered magnesium can ignite spntaneously at room temperture but a lump of magnesium would never light at room temperature. A rather complicated question

What is a good pictorial representation of an atom?
chemkid replied to Mag's topic in Modern and Theoretical Physics
I think what your really asking is what is our most current idesa of what an atom may perhaps look like. We really don't know very well, simply a hypotheesis. -
Be absolutly critical of every experiment and demand more evidence and answers to your every last question. Refuse to take i don't know as an answer. Critically survey every piece of data. Assume everything is false. Chemkid

Can You Help To Identify This Micro/Nano Object
chemkid replied to chaosonline's topic in The Lounge
Perhaps a piece of plastic? CD-rom plastic. Maybe tommorow i will take a phot of a small chip of mica under the microscope. -
I was going to post a new thread on this, but since this is here I'll add this: How would one determine whether or not a substance is polar? I understand that it has to do with different electron negativities and the electrons being closer to one atom than another. But how much more electron negative does one element in a compound have to be than the other in order for that compound to be polar? Also how does polarity relate to solubility? Just polar dissolved polar and non-polar non-polar or is there something more? Chemkid

Same here with the sparklers, doesn't mean you can't use them. (:

Any enzymes, proteins that kind of stuff, would likely denature. Depending on your voltage (and all those other confusing electrical factors) some of the carbohydrates and inorganic compounds would decompose as well. And of course water. Chemkid

I think i am qualified to write a text on why god doesn't exist. I am currently attending a highly rated school for the sciences, arts, and technologies. I have found some interesting data..... Bad things that happened to me today.... stubbed my toe, dropped a pen, my computer wouldn't turn on, i didn't sleep well, i burnt the oatmeal Good things... i ate breakfast My badness statistic clearly out weights my goodness statistic and assuming god is good, he can't possibly exists because bad things happened to me. Hows that for data? Chemkid

I don't know much about protiens in the tertiary structure, but i do know why i think! I enjoy thinking, it makes me happy

No books, just a lot of new glassware. chems etc.

What your looking for really varies with what you consider valid. There is no comprehensive, official English language, unlike a language such as french which has an official dictionary and committee electing new words to the language. For example, does Coca-cola count? Scientific names? Technical terms? Words like chlorate, chlorite, perchlorate, perchlorate, and chloride? It is very hard to say what is and isn't a word. Chemkid
