Professor Niels Harrit, is an associate professor of chemistry in the Department of Chemistry at the prestigious 9-Nobel-Laureate University of Copenhagen, Copenhagen, Denmark (see http://davidraygriffin.com/lectures/niels-harrit%E2%80%99s-lecture-on-the-world-trade-center/ ).
Professor Niels Harrit and colleagues in a scientific paper in a peer-reviewed journal re discovery of unexploded nanothermite in all World Trade Center (WTC) dust samples studied (2009): “We have discovered distinctive red/gray chips in all the samples we have studied of the dust produced by the destruction of the World Trade Center. Examination of four of these samples, collected from separate sites, is reported in this paper. These red/gray chips show marked similarities in all four samples. One sample was collected by a Manhattan resident about ten minutes after the collapse of the second WTC Tower, two the next day, and a fourth about a week later. The properties of these chips were analyzed using optical microscopy, scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy (XEDS), and differential scanning calorimetry (DSC). The red material contains grains approximately 100 nm across which are largely iron oxide, while aluminum is contained in tiny plate-like structures. Separation of components using methyl ethyl ketone demonstrated that elemental aluminum is present. The iron oxide and aluminum are intimately mixed in the red material. When ignited in a DSC device the chips exhibit large but narrow exotherms occurring at approximately 430 °C, far below the normal ignition temperature for conventional thermite. Numerous iron-rich spheres are clearly observed in the residue following the ignition of these peculiar red/gray chips. The red portion of these chips is found to be an unreacted thermitic material and highly energetic… having observed unignited thermitic material in the WTC residue, we suggest that other energetic materials suitable for cutter charges or explosives should also be looked for in the WTC dust. NIST [National Institute of Standards and Technology] has admitted that they have not yet looked for such residues… Based on these observations, we conclude that the red layer of the red/gray chips we have discovered in the WTC dust is active, unreacted thermitic material, incorporating nanotechnolgy, and is a highly energetic pyrotechnic or explosive material.

Professor Niels Harrit on the collapse of building WTC7 (limited damage, no extensive fires) (2007): “We are not talking about conspiracy theories, absolutely not. We are talking about elementary physics and chemical processes, Newton's laws, gravity, the melting point of steel, and the like… WTC7 did not. After the building had smouldered for seven hours, it collapsed, perfectly symmetrically. It was quite literally levelled, and ended up as a pile that was basically confined to its footprint. The process took 6.4 seconds, which is equivalent to "free fall". If you had stood on the 47th floor and thrown an apple out the window at the exact moment the collapse began, your apple would have hit the ground at the same time as the roof. How could it happen? In the hours following the airplane strikes on the two towers, a global myth began to spread that the World Trade Centre collapsed due to fire and mechanical damage. The only problem is that no steel structure has ever before collapsed due to fire, it is historically unprecedented. Over 400 cases of fire in that type of skyscraper are known prior to 2001, and none have collapsed. Not one. … Two official explanations of the events in Manhattan on 11 September have been put forward by the Federal Emergency Management Agency (FEMA), and the National Institute for Standards and Technology (NIST). In the final FEMA report, WTC7 is hardly mentioned. They note that there were fires in the building, but do not attempt to explain the collapse. NIST actually took the sensible step of engaging a company to construct models of the steel structure in the two towers. The models were then exposed to fires and damage. Even though temperatures were used which were significantly higher than what could have resulted from the attack, they were unable to provoke a collapse. The models remained standing. NIST chose, however, to ignore this result… The attack on the World Trade Center was a tragedy for the people in the towers and in the airplanes, and a tragedy for their families. It also marked the beginning of the tragic war on terror. The current trends in Western society towards greater surveillance and the loss of civil rights can also only be called tragic. If we have also been lied to, the tragedy is complete. How did WTC7 collapse? We are not asking 'why'. This is no conspiracy theory. There is no burden of proof on us. Some extremely simple observations have been made, and we want to hear an official explanation that is consistent with elementary physics and chemistry, and common sense. If you want to investigate the conditions described above, you won't find anything in the media. But Google something like 'WTC7' and you will find a flood of information. There are tens of thousands of people who have a feeling something is wrong. But there is not a word about it in the media.” [2].
