چکیده

Spectroscopic factors and asymptotic normalization coefficients ~ANCs! have been determined for bound states in O using the N(He,d)O reaction. These results are used to calculate the astrophysical S factor for direct capture in the N(p ,g)O reaction. We also discuss how uncertainties in optical-model parameters influence both the spectroscopic factors and the ANCs, and the effect that this has on the predicted directcapture reaction rate.

Theoretical Investigation of the Reaction Mechanism for a Type of N-heterocyclic Compound Involving Mono-N-aryl-3-aminodihydropyrrol

The kinetics of reaction between 4-methylaniline (1), dimethyl acetylenedicarboxylate (2) and formaldehyde (4) has been theoretically investigated to gain further insight into the reaction mechanism. The results of theoretical calculations were achieved using the ab initio method at the HF/6-311g (d, p) level of theory in gas phase. The mechanism of this reaction had 5 steps. Theoretical kineti...

Pd and Fe3O4 Nanoparticles Supported on ‎N-(2-Aminoethyl)Acetamide Functionalized ‎Cellulose as an Efficient Catalyst for ‎Epoxidation of Styrene

A new efficient heterogeneous catalyst was introduced for the epoxidation of styrene. The catalyst was obtained from functionalization of cellulose with N-(2-aminoethyl)acetamide, and then deposition of nanoparticles and Pd(0) nanoparticles on the modified cellulose. The Fe3O4 nanoparticles were deposited via chemical oxidation in basic media and Pd(0) nanoparticles we...
