Tracking degradation in lithium iron phosphate batteries using differential thermal voltammetry Toshio Shibagaki, Yu Merla, Gregory J Offer* Department of Mechanical Engineering, Imperial College London, United Kingdom * gregory.offer@imperial.ac.uk Keywords Lithium-ion battery Degradation State-of … This discussion has moved to GHOSTING DARK STAINS from AIR LEAKS.

Also see HUMIDITY CONTROL TO PREVENT MOLD. SandyMold can be of just about any color; some species, in very light deposits might look like soot but usually there's more texture.You don't normally see mold blowing out of a heating duct and onto nearby surfaces in a thermal tracking pattern such as shown on these pages but I can't say it's impossible.When you see any sooty material coming out of a heating duct- if it's oil fired you suspect the system is not running properly, has a leaky heat exchanger, is blowing soot through the building and is possibly unsafe too- if it's gas fired heat, and the heater is producing soot, the system is very unsafe, risking fatal carbon monoxide poisoning, which is why I felt CO detectors are an urgent safety device to have properly installed and tested.House dust blowing through HVAC ducts also makes dark gray or even black "sooty" deposits on surfaces and can simply be due to having run the system without proper air filters.Perhaps hubby can post a photo - one per comment.
