Towards high accurate neutron-induced fission cross sections of 240,242Pu: Spontaneous fission half-lives

open access: yesEPJ Web of Conferences, 2013
Fast spectrum neutron-induced fission cross sections of transuranic isotopes are being of special demand in order to provide accurate data for the new GEN-IV nuclear power plants.

Bioinspired, Mitochondria‐Targeted Single‐Atom Nanozyme Enhances Bone Regeneration by Reprogramming Stem Cell Energy Metabolism​

open access: yesAdvanced Materials, EarlyView.
A bioinspired nanozyme—triphenylphosphonium (TPP)‐dendritic mesoporous silica nanoparticle (DMSN)‐Fe/Cu—mimics mitochondrial complex IV and targets mitochondria to regulate cellular energy metabolism. This approach markedly boosts bone regeneration in vivo, as demonstrated by enhanced bone volume and mineral density in critical‐sized bone defects rat ...

Applications of Event-by-Event Fission Modeling with FREYA

open access: yesEPJ Web of Conferences, 2012
The recently developed code FREYA (Fission Reaction Event Yield Algorithm) generates large samples of complete fission events, consisting of two receding product nuclei as well as a number of neutrons and photons, all with complete kinematic information.

Metal‐Metal‐π Interaction: A Pathway to Construct Organic–Inorganic Excited‐State and Supramolecular Assembly

open access: yesAdvanced Optical Materials, EarlyView.
An organic–inorganic mixed excited state is designed and demonstrated by combining the metal–metal and π–π interactions within a supramolecular Pt2–pyrene assembly. Directional orbital overlap between the Pt and carbon atoms gives rise to a long‐lived triplet emission, strong emission polarization, exciton–exciton annihilation, and efficient exciton ...

The 235U prompt fission neutron spectrum measured by the Chi-Nu project at LANSCE

open access: yesEPJ Web of Conferences, 2017
The Chi-Nu experiment aims to accurately measure the prompt fission neutron spectrum for the major actinides. At the Los Alamos Neutron Science Center (LANSCE), fission can be induced with neutrons ranging from 0.7 MeV and above.

Search for spontaneous fission of plutonium and americium nuclides using gamma spectrometry [PDF]

open access: yesЯдерна фізика та енергетика
Spontaneous fission in americium and plutonium isotopes was investigated using high-resolution gamma spectrometry. This process was investigated through analysis of a certified PuO2 sample spectrum obtained from the IAEA database of reference spectra ...

Cold fission as cluster decay with dissipation [PDF]

open access: yes, 2006
For cold (neutronless) fission we consider an analytical model of quantum tunneling with dissipation through a barrier U(q) evaluated with a M3Y nucleon-nucleon force. We calculate the tunneling spectrum, i.e., the fission rate as a function of the total

Lead reactor of small power with metallic fuel [PDF]

open access: yesNuclear Energy and Technology, 2018
The possibility for obtaining a hard neutron spectrum in small reactor cores has been considered. A harder spectrum than spectra in known fast sodium cooled and molten salt reactors has been obtained thanks to the selection of relatively small core ...
