A simple approach to the chaos-order contributions in nuclear spectra
, 2018 The simple one-parameter nearest neighbor-spacing distribution (NNSD) is suggested for statistical analysis of nuclear spectra. This distribution is derived within the Wigner-Dyson approach in the linear approximation for the level repulsion density of ...

A Stepwise Approach to 1,4,10,13‐Tetraaza‐18‐Crown‐6 Ether
ChemistryOpen, Volume 15, Issue 5, May 2026.A two‐step synthetic strategy to tetraaza‐18‐crown‐6 was developed to overcome the low yield of the conventional one‐step method. Optimized conditions significantly suppressed formation of the undesired nine‐membered ring. A three‐fold increase in yield of the macrocyclization step was obtained, or two‐fold when column chromatography was avoided. A two‐

Density functional study of the actinide nitrides
, 2009 The full potential all electron linearized augmented plane wave plus local orbitals (FP-LAPW + lo) method, as implemented in the suite of software WIEN2K, has been used to systematically investigate the structural, electronic, and magnetic properties of ...

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.The local carbon environment in the refractory transition metal carbides ZrC, HfC, NbC, and TaC was studied using high‐resolution magic angle spinning 13C NMR spectroscopy. Results show that carbon nuclei with next nearest neighbor vacant sites or oxygen/nitrogen impurities are distinguishable through 13C NMR, and that the technique can be used to ...

Cluster radioactivity in $^{114}$Ba in the HFB theory
, 2011 Cluster radioactivity in $^{114}$Ba is described as a spontaneous fission with a large mass asymmetry within the self-consistent HFB theory. A new fission valley with large octupole deformation is found in the potential energy surface.

Theoretical Prediction of Divalent Actinide Borozene Complexes
MoleculesThe aromatic boron cluster B82– (D7h) has similar π bonding to C6H6, which is named “borozene”. The B82– ligand has been observed to stabilize monovalent Ln(+I) in C7v-LnB8− (Ln = La, Pr, Tb, Tm, and Yb) borozene complexes. Low-valency actinide complexes

Nitric acid-organic mixtures surveyed for use in separation by anion exchange methods [PDF]
, 1968 Column elution-spectrographic analysis technique compares certain solvents directly to the methanol system, using inert rare earths instead of actinides. Distribution ratios for americium between 90 percent solvent, 10 percent 5 M nitric acid and Dowex 1
