Possible Impurities in Radiopharmaceuticals and Corresponding Test Methods
Регуляторные исследования и экспертиза лекарственных средств, 2022 The main quality attributes of radiopharmaceuticals that ensure their effectiveness and safety and are unique to their specifications are activity, radionuclide identity, radionuclide purity, and radiochemical purity. The aim of this study was to analyse

Chemistry – A European Journal, EarlyView.Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Lifetime measurements and decay spectroscopy of 132I
EPJ Web of Conferences, 2014 The low-lying states of odd-odd 132I, the 3p-3h nucleus with respect to the doubly magic 132Sn, have been characterized from decay spectroscopy. The neutron rich Iodine and Tellurium isotopes have been produced as fission product of alpha-induced fission

On-line Excited-State Laser Spectroscopy of Trapped Short-Lived Ra$^+$ Ions [PDF]
, 2010 As an important step towards an atomic parity violation experiment in one single trapped Ra$^+$ ion, laser spectroscopy experiments were performed with on-line produced short-lived $^{212,213,214}$Ra$^+$ ions. The isotope shift of the $6\,^2$D$_{3/2}$\,-\

Boron Neutron Capture Therapy at a Crossroads: Translational Gap and Emerging Delivery Agents
Chemistry – A European Journal, EarlyView.This review surveys recent advances in boron delivery agents for BNCT, emphasizing the shift from classical small molecules to multifunctional nanocarriers and theranostic systems. By integrating targeting, imaging, and therapy, next‐generation boron compounds aim to bridge the gap between (bio)chemical innovation and clinical translation.

Ion–Molecule Reaction Products as Probes and Precursors for Preparative Mass Spectrometry
Chemistry – A European Journal, EarlyView.Ion–molecule reactions in the gas phase of mass spectrometers are important for preparative mass spectrometry because they (1) provide knowledge about the intrinsic reactivity of ions, helping to predict and control their reactivity at interfaces, and (2) generate new complex ions that can be mass selected and deposited on surfaces.
