Determination of fission fragment yields using the sorbtion process [PDF]

Ядерна фізика та енергетика, 2007
The separation of iodine isotopes from the sum of 235U fission products by the sorption process from water solution using coal sorbent SKS was investigated. The sorption coefficient values in range 0,7 - 0,9 was obtained.

Studies of the $^{1}$S$_{0}$--$^3$P$_0$ transition in atomic ytterbium for optical clocks and qubit arrays

, 2005
We report an observation of the weak $6^{1}$S$_{0}$-$6^3$P$_0$ transition in $^{171,173}$Yb as an important step to establish Yb as a primary candidate for future optical frequency standards, and to open up a new approach for qubits using the $^{1}$S$_{0}

Lymphoma, multiple myeloma and leukaemia incidence in regions of Belarus most heavily contaminated by the Chernobyl accident

International Journal of Cancer, EarlyView.
What's New? The 1986 Chernobyl accident led to widespread radioactive contamination across parts of Europe, with elevated childhood leukaemia rates observed in heavily affected areas of Ukraine. Data on long‐term haematological and other non‐thyroid cancer risk in the general population in heavily contaminated regions, however, remain limited.

Axillary management after neoadjuvant therapy for breast cancer and optimization of sentinel lymph node diagnosis and treatment [PDF]

Zhongguo aizheng zazhi
The axillary management of breast cancer patients after neoadjuvant therapy (NAT) is undergoing optimization. Sentinel lymph node biopsy (SLNB) has become an important means for evaluating the status of axillary lymph node (ALN), especially in early ...

Isotope shifts of 6s5d $^3$D-states in neutral Barium

, 2008
Laser spectroscopy of the low lying $^1$P and $^3$D states in atomic barium has been performed. This work contributes substantially to the development of an effective laser cooling and trapping for heavy alkaline earth elements and aims in particular for

2,3‐Dichloro‐5,6‐Dicyano‐1,4‐Benzoquinone (DDQ)‐Mediated CC Bond Formation: Redox Strategies from Stoichiometric to Catalytic Systems

ChemistryOpen, EarlyView.
2,3‐Dichloro‐5,6‐dicyano‐1,4‐benzoquinone serves as a versatile oxidant and redox catalyst for CC bond formation through hydride abstraction or single‐electron transfer. Stoichiometric and catalytic systems enable benzylic, allylic, and aromatic CH activation under mild, metal‐free conditions, providing sustainable routes to complex and bioactive ...

Noble gases and nitrogen in material from asteroid Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.
