Monitoring the Effect of Calcium Nitrate on the Induction Period of Cement Hydration via Low-Field NMR Relaxometry [PDF]

open access: yesMolecules, 2023
The hydration process of Portland cement is still not completely understood. For instance, it is not clear what produces the induction period, which follows the initial period of fast reaction, and is characterized by a reduced reactivity.

Observation of induction period and oxygenated intermediates in methane oxidation over Pt catalyst [PDF]

open access: yesiScience, 2023
Summary: Selective oxidation of methane is one of the most attractive routes for methane to chemicals. However, mechanistic understanding and avoiding over-oxidation have great challenges because of its very rapid reaction rate. Herein, a capillary micro-

Period relations for automorphic induction and applications, I [PDF]

open access: yesComptes Rendus. Mathématique, 2014
Let K be a quadratic imaginary field. Let Π (resp. Π′) be a regular algebraic cuspidal representation of GLn(AK) (resp. GLn−1(AK)), which is moreover cohomological and conjugate self-dual. When Π is a cyclic automorphic induction of a Hecke character χ over a CM field, we show relations between automorphic periods of Π defined by Harris and those of χ.

Probing intermediates of the induction period prior to nucleation and growth of semiconductor quantum dots [PDF]

open access: yesNature Communications, 2017
Growth of colloidal semiconductor quantum dots involves several stages, including an enigmatic induction period preceding nucleation. Here, the authors identify two distinct intermediates in the induction period, mapping their evolution from precursors ...
