Herein,we adopt a simple supramolecular strategy to effectively control the tautomerism of ureidopyrimidinone(UPy)moiety and ultimately realize the complete arrangement of enol configuration.The obtained UPy derivativ...
Large neutron absorption resonances in the nuclides present in irradiation samples reduce the irradiating neutron flux at energies close to a resonance.In neutron activation analysis of optically thick samples with re...
Various approaches and models are used in deterministic codes to treat the resonance self-shielding behavior of cross-sections.The accuracy of the models used has a significant effect on the precision of calculations;...
At present,in the cyclotron which is used in the production of short and medium life isotopes for medical use,neutron and gamma ionizing radiation will be produced when the target system and cyclotron are running.Acco...

Practically all physical, chemical, and biologi- cal processes can induce mass-dependent fractionation of mercury (Hg) isotopes. A few special processes such as photochemical reduction of Hg(Ⅱ) and photochemical ...
We investigate a new approach for resonance self-shielding calculations, based on a straightforward subgroup method, used in association with characteristics method. Subgroup method is actually the subdivision of cros...
Accurate neutron flux values in irradiation channels of research reactors are very essential to their usage. The total neutron flux of the Ghana Research Reactor-1(GHARR-1) was measured after a beryllium reflector was...
This paper describes the structure and work principle of a miniature and self-shielding electron-beam radiation processing system.Centering on the miniaturization and self-shielding,this system has been manufactured. ...

A NFFP HVI structure which implements high breakdown voltage without using additional FFP and process steps is proposed in this paper. An 850 V high voltage half bridge gate drive IC with the NFFP HVI structure is exp...
China Institute of Atomic Energy (CIAE) has developed a self-shielding electron beam installationfor sterilization as handling letters with anthrax germ or spores which has the least volume and the
