       The Self-Propagating High temperature Synthesis (SHS) is an engineering technique developed to synthesize high-grade ceramic materials such as refractory, ceramic matrix composites, intermetallic compounds, and functional grade materials. Because of its energy efficiency and low cost compared to the original technique, SHS is combined with centrifugal casting to synthesize composite material inside metal pipe to extend the pipe’s longevity.

       Formalin is known as embalming solution, which is commonly used to preserve dead bodies. With this known property, the solution has been illegally used to preserve vegetables and meat. Formalin is thus usually found in fresh seafood, vegetables, and meat. Too much residue of formalin could cause harm to consumers. Some of the symptoms are irritation inside the mouth and throat. In some cases of hypersensitivity, formalin can cause headache, difficulty breathing, and tightness in the chest. Contact with formalin at 2-10% concentration can cause skin infection. Moreover, formalin can also cause cancer in human.
