These particles can be carried downstream with the exhaust and collect on the diesel particulate filter. These ash particles cannot be removed by filter regeneration because they are not coustible. As the ash particles accumulate, they result in filter blockage that increases back pressure to the engine, increasing fuel consumption and decreasing power.

Calcium carbonate - Wikipedia
Calcium carbonate is a chemical compound with the formula Ca CO 3.It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs., and eggs.
Lithium-ion Safety Concerns – Battery University
Lithium-ion Safety Concerns When Sony introduced the first lithium-ion battery in 1991, they knew of the potential safety risks. A recall of the previously released rechargeable metallic lithium battery was a bleak reminder of the discipline one must exercise when
sodium | Facts, Uses, & Properties | Britannica
Sodium, chemical element of the alkali metal group in the periodic table. Properties and production Because sodium is extremely reactive, it never occurs in the free state in Earth’s crust. In 1807 Sir Humphry Davy became the first to prepare sodium in its elemental form, applying electrolysis to fused sodium hydroxide (NaOH).
Baerlocher: Metal Soaps
Metal soaps are derived from long-chain fatty acids and a metal oxide compound. The fatty acids, in turn, are derived from a triglyceride (natural fats and vegetable oils, i.e. renewable feedstocks). Metal soaps – commonly known as metallic stearates – can be
Deposition Methods for Microstructured and …
As the particles are not molten or semimolten, cold spray adhesion can be relatively high. High kinetic energy results in cleaning (removal of oxidation) and activation of the substrate. Each subsequent layer of coating sprayed further bonds the previous layer allowing excellent metallurgical bonding …
Perovskite Solar Cell - Clean Energy Institute
Using photoluminescence captured by high-speed video, Hillhouse and his group are testing a variety of hybrid perovskites for long-term stability. These experiments generate enormous data sets, but by using machine learning, they aim to generate a predictive model of degradation for perovskite solar cells.
