Nonlinear generation of non-acoustic modes by low-frequency sound in a vibrationally relaxing gas
PublicationTwo dynamic equations referring to a weakly nonlinear and weakly dispersive flow of a gas in which molecular vibrational relaxation takes place. are derived. The first one governs an excess temperature associated with the thermal mode, and the second one describes variations in vibrational energy. Both quantities refer to non-wave types of gas motion. These variations are caused by the nonlinear transfer of acoustic energy into...

Effects of metallic silver particles on resonance energy transfer between fluorophores bound to DNA.
PublicationZbadano wpływ filmów wysepek metalicznego srebra na rezonansowe przekazywanie energii między fluoroforami związanymi z DNA. Donorem i akceptorem były odpowiednio 4´,6 diamidyno-2-fenylindon i jodek propydyny. Zmierzone dla tego układu czasy zaniku i widma fluorescencji pokazują, że sąsiedztwo cząstek srebra dramatycznie zwiększa promień Forstera, a tym samym i przekazywanie energii w znakowanym DNA.
