Aerosol Inhalation Delivery of Ceftriaxone in Mice: Generation Procedure, Pharmacokinetics, and Therapeutic Outcome

Antibiotics, 2022
Aerosol inhalation delivery of ceftriaxone in mice was investigated. An ultrasonic nebulizer within the ranges of mean particle diameter 0.5–1.5 μm and mass concentration 0.01–0.6 μg/cm3 was used in inhalation experiments.

Fast intersystem crossing in the tetracene dimers as a source of “dark” state

AIP Advances, 2023
Tetracene (Tc) is a prototype material undergoing singlet fission (SF), the formation of a pair of triplet excitons from a singlet exciton. The tetracene dimer Tc2 is supposed to be a structural unit providing SF behavior.

Collective behaviours: from biochemical kinetics to electronic circuits [PDF]

, 2013
In this work we aim to highlight a close analogy between cooperative behaviors in chemical kinetics and cybernetics; this is realized by using a common language for their description, that is mean-field statistical mechanics.
