Amplified biochemical oscillations in cellular systems

, 2006
We describe a mechanism for pronounced biochemical oscillations, relevant to microscopic systems, such as the intracellular environment. This mechanism operates for reaction schemes which, when modeled using deterministic rate equations, fail to exhibit ...

Synthesis of CoAl2O4 by double decomposition reaction between LiAlO2 and molten KCoCl3 [PDF]

, 2008
Submicronic CoAl2O4 powders were prepared by double decomposition reaction between solid LiAlO2 and molten KCoCl3 at 500 ◦C for 24 h. The reaction mechanism involves the dissolution of LiAlO2 shifted by the precipitation of CoAl2O4 until complete ...

One- and two- neutron halo at the dripline. From 11Be to 11Li and back: 10Li and parity inversion

, 2018
The nuclei 11Be and 11Li provide paradigmatic examples of one-and two- neutron halo systems. Because the reaction 1H(11Li,9Li)3H is dominated by successive transfer, one can use the quantitative picture emerging from a nu- clear field theory description ...

Isotope Labelling for Reaction Mechanism Analysis in DBD Plasma Processes [PDF]

, 2019
Dielectric barrier discharge (DBD) plasmas and plasma catalysis are becoming an alternative procedure to activate various gas phase reactions. A low-temperature and normal operating pressure are the main advantages of these processes, but a limited ...
