Not new, per se, but I just found this.
The Top Ten Connections Between NIST and Nano-Thermites
... despite a number of variations in NIST’s story, it never considered explosives or pyrotechnic materials in any of its hypotheses. This omission is at odds with several other striking facts; first, the requirement of the national standard for fire investigation (NFPA 921), which calls for testing related to thermite and other pyrotechnics, and second, the extensive experience NIST investigators have with explosive and thermite materials.
...
... It turns out that explosive, sol-gel nano-thermites were developed by US government scientists, at Lawrence Livermore National Laboratories (LLNL) (Tillitson et al 1998, Gash et al 2000, Gash et al 2002). These LLNL scientists reported that -- “The sol-gel process is very amenable to dip-, spin-, and spray-coating technologies to coat surfaces. We have utilized this property to dip-coat various substrates to make sol-gel Fe,O,/ Al / Viton coatings. The energetic coating dries to give a nice adherent film. Preliminary experiments indicate that films of the hybrid material are self-propagating when ignited by thermal stimulus” (Gash et al 2002).
Kevin Ryan is the lab director who was allegedly fired from Underwriters Laboratories (the company that certified the WTC steel) for voicing his skepticism of the NIST report on the WTC collapses.
