1.Reactant of NiSO_4 、K_4[Fe(CN)_6] and Cs~+ is infusibility Cs_2Ni[Fe(CN)_6] and Cs4Ni4[Fe(CN)_6]_3 solid solution . These solid solutions are retained by mechanical sealing of solidification form.
Leaves of Phyllanthus singampattiana, locally known as Aathuchadai by the Kanis of Tamil Nadu in India is consumed for curing jaundice, diarrhea and dysentery.
Fourier transform infrared (FTIR) analysis was used to identify the chain structure of the UV-curable polyurethane prepolymer based on HTPB and the curing process.
When the content of nano-SiO2 was below 1.5%, the amount of free formaldehyde decreased, and the viscosity and bonding strength of resin increased with an increase in the added nano-SiO2, which did not prolong the curing time.
The curing behavior of BLF resin adhesive, studied by TG-DSC and IR analyses, showed that BLF resin adhesives had a lower curing temperature than PF adhesives but had the same characteristic trough in IR spectra as PF adhesives.
The calculation results indicated that the IHTC immediately increased after liquid metal was brought into the cavity by the plunger and decreased as the solidification process of the liquid metal proceeded.
Higher heating rate inhibits the further melting of adjacent matrix and the solidification of liquid by liquid-to-γ mode in the subsequent thermal cycle.
Creep-resistant magnesium alloy design, plastic processing of magnesium alloys and rapid solidification processing of magnesium alloys have become the hot topics in magnesium technology.
The cure kinetics was studied by dynamic DSC (differential scanning calorimetry) analysis, and the parameters of the cure reaction were obtained to establish a phenomenological model.
A new cure procedure of this practical thermosetting system was extracted from the TTT diagram by prolonging the pre-gel time to restrict the diffusion ability and the flow ability of the solution.
Effects of relative content of HTPB and PPG on emulsion stability, resistance to water and ethanol, thermal stability, compatibility of soft and hard segment, as well as the mechanical property of the cured film were investigated.
