Spontaneous ignition properties of the hexane isomers and other selected pure hydrocarbons in air were studied with the view to correlating these findings with molecular structure. Specifically, the influence of chain length, chain branching, unsaturation, and of cyclic and aromatic structures on the ...
of extended carbon structure (Fig. 3b). This is a process of dehydrogenation from alkane to conjugated hydrocarbon, and then to some carbon-based species. This process is basically initiated by thermal activation and could be promoted by laser. Upon cooling, the intensity of the peak at 1606 ...

(Hilmanto et al., 2016). Modification of the hydrophobic matrix may change the enzyme's structure from closed to open structure, which means that the substrate is easier to enter and bind at the active site (Chen et al., 2012).
Alkanes are an important part of petroleum, the stability of alkanes under extreme conditions is of great significance to explore the origin of petroleum and the carbon cycle in the deep Earth. Here, we performed Raman and infrared (IR) spectroscopy studies of n-hexane and cyclohexane under high...
Schematic overview of TPU The polyols used in this reaction are generally polyester, polyether or polycarbonate diols with molecular weights of between 1000 and 4000. Some common short-chain diols are butane diol, hexane diol or aromatic diols. For the diisocyanate component, diphenyl met...
