merril Posted May 6, 2009 #176 Share Posted May 6, 2009 marabod – these materials are not found in nature “intimately mixed” on a nano scale. A source of these elements might be abraded paints. For example, from the same report, page 157 Fire Resistance Tests of the Floor Truss Systems.

Q24 Posted May 7, 2009 #177 Share Posted May 7, 2009 A source of these elements might be abraded paints. I will quote straight from the paper that began this thread: - Initially, it was suspected these might be dried paint chips, but after closer inspection and testing, it was shown that this was not the case. The initial objective was to compare the behaviour of the red layer with paint when soaked in a strong organic solvent known to soften and dissolve paint. Red/gray chips were soaked in methyl ethyl ketone (MEK) for 55 hours with frequent agitation and subsequently dried in air over several days. The chips showed significant swelling of the red layer, but with no apparent dissolution. In marked contrast, paint chips softened and partly dissolved when similarly soaked in MEK. Several paint samples were also tested and in each case, the paint sample was immediately reduced to fragile ashes by the hot flame. This was not the case, however, with any of the red/gray chips from the World Trade Center dust. Given the small size of the red chip, about 0.5 mm x 0.5 mm, we used two probes and obtained a rough value of approximately 10 ohm-m. This is several orders of magnitude less than paint coatings we found tabulated which are typically over 1010 ohm-m. The post-DSC-test residue contains microspheres in which the iron exceeds the oxygen content, implying that at least some of the iron oxide has been reduced in the reaction. If a paint were devised that incorporated these very energetic materials, it would be highly dangerous when dry and most unlikely to receive regulatory approval for building use. As suggested, that would be some very unusual and dangerous paint. Link to comment Share on other sites More sharing options...

aquatus1 Posted May 7, 2009 #180 Share Posted May 7, 2009 Well, please forgive the lack of quips and comebacks. They were there, but for some reason, my original post is not here. Can we talk in degree Celsius (oC) rather than degree Fahrenheit (oF) though please? Celsius seems the primary measurement and is used throughout the NIST WTC investigation. Just I was a little shocked to read thermite burns at “4,500 degrees” before I realised what was going on! I'll do my best, but I'm going to ask for a little larger margin of error, as Celsius is foreign to me. Also I do not believe the thermite would be pooling anywhere for any amount of time. The theory that metal sat nicely in a little ‘pooling cup’ while being heated and then throwing itself out of the building is all of the official story’s making – not one I find plausible. Pretty much as soon as the charge is initiated and the reaction begins I believe the flow becomes visible. Excellent. Thank you for clarifying. Aw, and I thought you were going to show how the flow cannot be thermite. Oh, really now, like anyone could type one post and ever convince you of anything. We are in the middle of showing you how the flow isn't thermite right now. So, when we last left our heroes, they had determined that the flow could not have been pooled, but rather must have been created spontaneously and flowed straight out the window. But this leads us to a conundrum. One of the defining properties of thermite is its conductivity. The reason it is so good at melting things is because it can pass the heat from within itself to other objects insanely quickly. Unfortunately, this exact same property also means that thermite rapidly loses heat, and along with that, fluidity. Pure thermite can flow quite well for four or five feet before it loses its plasticity and solidifies. Mixed thermite much less so. The moment thermite begins mixing with whatever steel or concrete it is melting, it loses heat to those materials. You have doubtless already seen several videos of people using different thermitic methods to melt various things. You can see them cutting apart steel girders or concrete blocks, and what you see when they are done are ugly drippings of metal hanging off the column, often solidified in place before they even reached the ground. Mixed thermites can flow maybe 2 feet before solidifying. And so our problem. With such a rapid onset of solidification, how can this flow be thermite?

MARAB0D Posted May 7, 2009 #181 Share Posted May 7, 2009 The chips showed significant swelling of the red layer, but with no apparent dissolution. In marked contrast, paint chips softened and partly dissolved when similarly soaked in MEK. Iron Oxide, used in thermite, does not contain any material, which can cause particles of it to swell in MEK. It is only some organic base, which can swell in it or dissolve - but when being mixed with such, Iron Oxide can not be used for thermite, as the base would isolate it from Aluminium and the reaction would not take off. Direct contact of the reagents is paramount for any chemical reaction! Moreover, the speed of any reaction in solid phase is proportional to the surface area of contact between the reagents, and all "nano-thermites" only make sense when they do not contain any agents, isolating the components, otherwise why bother grinding Fe2O3 and Al so fine to just agglomerate them back into the lumps??? What it probably was - just paint chips, previously heated or aged enough for the epoxy base to lose its porosity and contained water. I doubt very much that solidified epoxy dissolves in MEK at all, because it is a polymer - however I have to admit that I never tried doing this myself, maybe the fresh one does it... However I know that epoxy indeed tends to swell in organic solvents. Link to comment Share on other sites More sharing options...

Q24 Posted May 7, 2009 #183 Share Posted May 7, 2009 We are in the middle of showing you how the flow isn't thermite right now. As of right now I can’t even see you have started showing how the flow cannot be thermite. But this leads us to a conundrum. One of the defining properties of thermite is its conductivity. The reason it is so good at melting things is because it can pass the heat from within itself to other objects insanely quickly. I agree, thermite can transfer heat very quickly but it should be noted, obviously not instantly. Pure thermite can flow quite well for four or five feet before it loses its plasticity and solidifies. Mixed thermite much less so. The moment thermite begins mixing with whatever steel or concrete it is melting, it loses heat to those materials. I will take your word for how far thermite can travel as there is no reason the flow cannot have originated within 5 feet of the window. You have doubtless already seen several videos of people using different thermitic methods to melt various things. You can see them cutting apart steel girders or concrete blocks, and what you see when they are done are ugly drippings of metal hanging off the column, often solidified in place before they even reached the ground. Mixed thermites can flow maybe 2 feet before solidifying. I have seen videos as you suggest where thermite is used for cutting and the metal solidifies fairly quickly. I have also seen videos such as where thermite quickly flows over a surface that it is capable of melting through. And so our problem. With such a rapid onset of solidification, how can this flow be thermite? Thermite does not necessarily solidify rapidly if it is not in contact, or only in fleeting contact, with a surface for it to transfer heat to. As seen in the video above, thermite is capable of melting through and mixing with the material of the car but because of the violent reaction and slope of the bonnet a large amount of the thermite continues to flow. Where are we up to? A displaced charge for which thermite becomes visible upon activation, located close to the window. This sounds well within reason.

I agree, thermite can transfer heat very quickly but it should be noted, obviously not instantly. Okay... So, insanely quickly is acceptable? I will take your word for how far thermite can travel as there is no reason the flow cannot have originated within 5 feet of the window. Please clarify: With this statement, are you claiming that the flow is pure thermite, with little metal, or are you claiming that it is thermite that has melted a large chunk of steel I have seen videos as you suggest where thermite is used for cutting and the metal solidifies fairly quickly. I have also seen videos such as where thermite quickly flows over a surface that it is capable of melting through. Yes indeed, and that is why I specified about pure thermite. As you can see, the unmixed thermite is quite liquid and splashes and flows freely. It's so hot that it glides over a little bit of melt, like an icecube. It is this property, in fact, that makes it useless for melting through vertical columns, but we'll get to that later.

As seen in the video above, thermite is capable of melting through and mixing with the material of the car but because of the violent reaction and slope of the bonnet a large amount of the thermite continues to flow. Yes, the thermite that is mixed with the melt cools much faster than the thermite that remains pure. Where are we up to? We're still on reason #1. A displaced charge for which thermite becomes visible upon activation, located close to the window. This sounds well within reason. Well, maybe, but let me get a clarification for the above first.

Q24 Posted May 7, 2009 #185 Share Posted May 7, 2009 Then you need to pay more attention. Maybe you need to put forward better reasons. So, insanely quickly is acceptable? I would prefer to drop the “insanely”. Please clarify: With this statement, are you claiming that the flow is pure thermite, with little metal, or are you claiming that it is thermite that has melted a large chunk of steel As the WTC2 thermite is flowing and at an extreme temperature, I would assume it is mostly pure thermite with little additional metal. Yes indeed, and that is why I specified about pure thermite. As you can see, the unmixed thermite is quite liquid and splashes and flows freely. It's so hot that it glides over a little bit of melt, like an icecube. It is this property, in fact, that makes it useless for melting through vertical columns, but we'll get to that later. Well that would depend how the thermite charge is setup against the column. We're still on reason #1. Link to comment Share on other sites More sharing options...
aquatus1 Posted May 7, 2009 #186 Share Posted May 7, 2009 Maybe you need to put forward better reasons. Nope. You only get one at a time. I would prefer to drop the “insanely”. Then we need to keep in mind that "quickly" in reference to thermite conductivity is something far different than "quickly" in terms of demo charges and "quickly" in terms of regular metal. Frankly, it's a little to unspecific for me, and I know that you take advatage of being unspecific to wriggle around too much. As the WTC2 thermite is flowing and at an extreme temperature, I would assume it is mostly pure thermite with little additional metal. Well that would depend how the thermite charge is setup against the column. As I said, we'll get to that later. First settle one point, then we can move on. Yep. I know you like to jump from topic to topic anytime you run out of things to say, making it look like you aren't losing any arguments. I'm not giving you that option.

MARAB0D Posted May 7, 2009 #187 Share Posted May 7, 2009 (edited) But, according to the paper, the red layer did swell and the reaction did ‘take off’. So there obviously is a thermite mix that performs this way and what you are saying is not necessarily true in all cases. We are talking about a microscopic observation! Can you advise, how can one evaluate this "take off" under a microscope? By "extensive white smoke" from the sample slide? How can you even heat a nano-size piece of sample when at these levels of magnification any normal microscope has an optical part almost touching the sample? Apparently they hardly could do anything else, but placing a pinch of this dust onto a coiled wire and bringing it into the Bunsen burner flame - and this must surely produce at least one visible tiny spark, as any city dust has something combustible in it. Remember, that this all was reported by the same Chemist who estimated 10 to 100 tons of thermite, planted into the building! By now he is probably already selling v!agra on the net, and you are still studying his "report"...

MARAB0D Posted May 8, 2009 #190 Share Posted May 8, 2009 only to clear up - a particle sized at 1 nm would look under a 1000x microscope (and that is a LARGE magnification!), as 1 micron would look to a naked eye. At the same circumstances a particle sized 1 micron would appear to look 1 millimetre large. It is much easier to do a genetic engineering, than to ignite a nano-size particle under a microscope.

Q24 Posted May 9, 2009 #193 Share Posted May 9, 2009 As I said, we'll get to that later. First settle one point, then we can move on. Yep. I know you like to jump from topic to topic anytime you run out of things to say, making it look like you aren't losing any arguments. I'm not giving you that option. It’s comical how you accuse me of topic jumping. Look at my responses and you will see the only times I deviate slightly are where either it is directly relevant or YOU have brought another issue into the discussion. For example: - In your post #185 above, you introduced, “It is this property, in fact, that makes it useless for melting through vertical columns, but we'll get to that later.” Now I’m sure you would like to get away with this erroneous statement but it deserves immediate response to correct - “Well that would depend how the thermite charge is setup against the column.” Then you act as though I’m the one jumping topic, “As I said, we'll get to that later.” What is happening here is that you can throw in additional issues when you like but you berate me for responding to them! As I said, quite comical. Anyhow your insistence on limiting discussion to the thermite flow seems to have brought us to a bit of a dead end where I have responded to your doubts and there is nothing left to address. Unless you actually have a reason that can be upheld, then there is nothing to say that the WTC2 visible flow is not thermite. Link to comment Share on other sites More sharing options...

MARAB0D Posted May 9, 2009 #197 Share Posted May 9, 2009 LOL, acid - what is YOUR credentials allowing you to ask for credentials? This is a forum, I am saying something, Chemistry-related - if you disagree and possess no expertise to challenge me yourself, you are always welcome to provide a link to a respected chemical source, which proves me wrong. Such source can be an approved text book, an extract from university lectures, CRC book, patent text, Chemical Encyclopaedia etc - but it can not be a politicised article, using chemistry-related terminology to support a conspiracy theory. In the general case, however, you can simply perform an experiment to make sure if I was misinterpreting something - for example in the current case you can try to ignite a nanoparticle under a microscope or to examine the dust from your own window frame and try to discover in it an airborne piece of 3 mm size.

Dust is just dust, nothing more, and there can not be giant steel beams or fragments of human remains in it, you confuse the "dust" with the "rubble". It is precisely the dust which was sampled and studied, not the rubble. Dust is always airborne, and 3-mm pieces can not be airborne and can not freely travel in the air, unless we are talking some sort of a sandstorm.

MARAB0D Posted May 9, 2009 #200 Share Posted May 9, 2009 Dust is a general name for minute solid particles with diameters less than 20 thou (500 micrometers). Particles in the atmosphere arise from various sources such as soil dust lifted up by wind, volcanic eruptions, and pollution. Dust in homes, offices, and other human environments consists of human skin cells, plant pollen, human and animal hairs, textile fibers, paper fibers, minerals from outdoor soil, and many other materials which may be found in the local environment.[1] http://en.wikipedia.org/wiki/Dust Link to comment Share on other sites More sharing options...
