Pionic hydrogen and friends
Pion-nucleon scattering lengths are directly related to the ground-state level shift and broadening in pionic hydrogen as well as to the pionic deuterium level shift. The level broadening in deuterium measures...

Catalysis of O-(para-nitrophenyl) O,O-dimethyl thiophosphate decomposition by chromonic mesophases based on polymerized ionic amphiphiles
The formation of a nematic chromonic mesophase in aqueous solutions of quaternized poly(ethylene imine) has been found using polythermal polarization microscopy. The reaction kinetics of O-(para-nitrophenyl) O,O-...

On kaonic hydrogen. Phenomenological quantum field theoretic model revisited
We argue that due to isospin and U-spin invariance of strong low-energy interactions the S-wave scattering lengths a 0 0 and a 1 0 of ¯N scattering with isospin I = 0 and I = 1 satisfy the low-energy theorem a 0

From solar proton burning to pionic deuterium through the Nambu-Jona-Lasinio model of light nuclei
Within the Nuclear Nambu-Jona-Lasinio model of light nuclei (the NNJL model), describing strong low-energy nuclear interactions, we compute the width of the energy level of the ground state of pionic deuterium...

On kaonic deuterium. Quantum field-theoretic and relativistic covariant approach
We study kaonic deuterium, the bound K-d state AK d. Within a quantum field-theoretic and relativistic covariant approach we derive the energy level displacement of the ground state of kaonic deuterium in terms o...

The Effect of Assembled Amphiphiles on Catalytic Reactions in Aqueous Media
Micelle-forming amphiphiles can promote catalyzed reactions in aqueous media. An example is the asymmetric hydrogenation of amino acid precursors. In comparison to the most common solvent methanol, the hydroge...
