Picosecond Dynamics of Proton Transfer of a 7-Hydroxyflavylium Salt in Aqueous-Organic Solvent Mixtures
(AMER CHEMICAL SOC, 2011)
The intermediacy of the geminate base proton pair (A*center dot center dot center dot H(+)) in excited-state proton-transfer (ESPT) reactions (two-step mechanism) has been investigated employing the synthetic flavylium ...
Padrão espacial de cinco espécies arbóreas no remanescente florestal da UTFPR - câmpus Dois Vizinhos
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilEngenharia FlorestalUTFPR, 2018-06-29)
Identifying the spatial pattern of forest species is fundamental to access the ecological processes of a tree community, as well as to define the levels of competitiveness among species and their form of seed dispersal, ...
Do regeneration traits vary according to vegetation structure? A case study for savannas
(Wiley-Blackwell, 2020-09-13)
Aim Regeneration traits are crucial for understanding patterns and processes in plant communities. However, regeneration traits are not reported much in community ecology, preventing a better assessment of trait-based ...
