| Just's team focused on emissions of ultrafine soot particles linked to some of the most serious health problems. |
| Similar effects have been shown following inhalation of ultrafine but not fine carbon black. |
| She said other researchers had shown that these ultrafine particles can carry toxic chemicals such as quinones and polycyclic aromatic hydrocarbons. |
| Then the system injects ultrafine sand that binds to floc and drags it to the bottom of a tube-lined tank. |
| A aoline ultrafine powder was obtained by ultrafine-crashing the mineral micropowders obtained from Fujian Tong'an Kaoline Factory. |
| The UltraTemp Filtration System is a hot gas filtration system that removes fine particulate, including submicron and ultrafine particles, to extremely low levels. |
