Impact of Nitrogen Fertilization Rate on Cured Leaf Quality and Chemistry of Flue-Cured Tobacco
2023Proper nitrogen fertilization is important for both yield and cured leaf quality of flue-cured tobacco. Optimizing the yield of high-quality tobacco is critical for grower profitability. A field study was conducted at the Virginia Tech Southern Piedmont Center near Blackstone, Virginia to investigate the relationship between nitrogen (N) fertilization ...

Surface chemistry of carbon black through curing process of epoxy resin
Carbon, 1995The effects of oxidized carbon black surfaces on the epoxy resin curing process were examined by differential scanning calorimetry (DSC). The addition of oxidized carbon black accelerated the initial cure reaction of the epoxy-amine system. Peak temperature in DSC exotherm of the resin system falls in proportion to the ratio of surface ester groups on ...

Chemistry, Characterization and Processing of IMC Curing Polymers.
1983Abstract : A variety of methods for a low-cost synthesis of the IMC curable monomer, 2,2'-bis(phenyl-ethynyl)-4,4',5,5'-tetraaminobiphenyl, were explored without success. A low-cost route was found for the preparation of the IMC curable monomer, 2,2'-bis(phenylethynl)-5,5'-diaminobiphenyl.

The Chemistry of Phthalic Anhydride in Cure Retardation of Rubbers
Rubber Chemistry and Technology, 1976Abstract Since we found no appreciable reaction between phthalic anhydride and cis-polyisoprene at 140°C, it is very unlikely that the scorch delay resulting from the use of phthalic anhydride is due to the blocking of cure sites of diene rubbers by phthalic anhydride.

Effect of Cement Chemistry on Accelerated Curing Cycle of Concrete
PCI Journal, 1984This paper presents the results of an investigation into improving the high early compressive strength of concrete containing Type III cement in a prestressed concrete manufacturing plant using accelerated curing techniques. The effects of physical and chemical cement characteristics are discussed with emphasis on C 3S and C3A contents, SO3 ...
