“…The formation of binary and ternary complexes was evaluated and, since epinephrine can behave as a zwitterion, the Eph (−)/Alg (2-) interaction was studied by means of DOSY NMR. The dependence of the equilibrium constants on ionic strength was studied using an extended Debye-Hückel type equation and the SIT approach. …”

“…We present evidence of the binding of daunomycin to parallel-stranded tetramolecular [d-(TTGGGGT)](4) guanine (G)-quadruplex DNA comprising telomeric DNA from Tetrahymena thermophilia by surface plasmon resonance and Diffusion Ordered SpectroscopY (DOSY). Circular Dichroism (CD) spectra show the disruption of daunomycin dimers, suggesting the end-stacking and groove-binding of the daunomycin monomer. …”

“…I pesticidi, in particolare gli insetticidi, oltre alle mortalità provocate da grossolani errori durante il loro impiego (interventi fitoiatrici eseguiti in fioritura, durante i flussi di melata, in presenza di vento, contaminazione della flora spontanea, ecc.), sono anche sospettati di abbassare, in dosi sub-letali, le difese immunitarie e di indurre alterazioni sul comportamento, sull’orientamento e sull’attività sociale delle api [1, 2].…”

“…The modified polyelectrolytes self-assembly in aqueous systems was monitored using diffusion-ordered nuclear magnetic resonance (DOSY NMR). The performed studies, supported by the all-atoms molecular dynamics simulations, revealed a strong dependence of polyelectrolyte self-assembled state on concentration—specific concentration regions with the coexistence of both smaller and larger aggregates were observed (values of hydrodynamic diameter D(H) around one nanometer and between two to six nanometers, respectively). …”

“…The selected experimental protocol uses a series of periods of irradiation and dark periods, thus providing opportunities to conduct an effective thiol–ene “click” reaction and simultaneously study the kinetics of the photochemical reaction with the exposure time, as well as macromolecular association directly in a solution applying the whole types of NMR methods: from conventional (1)H or (13)C NMR to diffusion NMR spectroscopy (DOSY). In addition, the molecular mass characteristics of the prepared copolymers were studied by gel-permeation chromatography (GPC). …”

(1)H-NMR nuclear magnetic resonance (DOSY and STD) were used as the main tools. The displacements observed in the (1)H-NMR presented the complexion between LAs and HP-βCD. …”

The addition of DMAP to the 1,3‐dioxa‐2‐phospholane facilitates the loss of ethene to give Ar(iPr4)(DMAP)PO(2) after days at room temperature, with this product also characterised by X‐ray crystallography and NMR spectroscopy. …”
