O comportamento Fotoquímico dos Complexos Pentaaminas de Rutênio(II) com Ligantes π Insaturados The photochemical behaviour of pentaamineruthenium(ii) complexes with unsaturated π ligands

Química Nova, 1997
A general overview on the photochemical behaviour of [Ru(NH3)5L]2+ complexes (where L is a p ligand) is presented. The proposed mechanisms and techniques employed for the study of these reactions are discussed.

Characterization of Turing diffusion-driven instability on evolving domains [PDF]

, 2012
In this paper we establish a general theoretical framework for Turing diffusion-driven instability for reaction-diffusion systems on time-dependent evolving domains.

Reaction mechanisms in heavy ion fusion

EPJ Web of Conferences, 2011
We discuss the reaction mechanisms involved in heavy ion fusion. We begin with collisions of tightly bound systems, considering three energy regimes: energies above the Coulomb barrier, energies just below the barrier and deep sub-barrier energies.

Diferentes estratégias para a reticulação de quitosana

Química Nova, 2011
One of the most important aspects of chitosan' derivatization depends on the crosslinking of their polymeric chains. This chemical strategy may confer new properties to those derivatives, which can be used to enhance their biotechnological applications ...

Deuteron-induced reaction mechanisms at low energies

EPJ Web of Conferences, 2012
An extended analysis of the reaction mechanisms involved within deuteron interaction with nuclei is presented. An increased attention is devoted to the breakup mechanism, all its components, namely the elastic, inelastic (fusion), and total breakup being

Momentum distributions and reaction mechanisms for breakup of two--neutron halos [PDF]

, 2000
A theoretical model able to describe fragmentation reactions of three--body halo nuclei on different targets, from light to heavy, is used to compute neutron and core momentum distributions.

Study of Reaction Mechanisms in α + 69Ga reaction at ≈10 – 50 MeV

East African Journal of Biophysical and Computational Sciences, 2023
The excitation functions of 69Ga(α, n)72As, 69Ga(α, 2n)71As, 69Ga(α, 3n)70As, 69Ga(α, x)69Ge, 69Ga(α, x)68Ga and 69Ga(α, x)67Ga reactions produced in the interaction of α-projectile with 69Ga-target were studied at ≈ 10-50 MeV.

Reaction mechanisms of pair transfer

, 2013
The mechanisms of nuclear transfer reactions are described for the transfer of two nucleons from one nucleus to another. Two-nucleon overlap functions are defined in various coordinate systems, and their transformation coefficients given between ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
