Dressed potential matrix

A similar analysis can be performed for the dressed potential energy surfaces. Combining Eqs. (7.4), (7.16) and (7.18), the elements of the dressed diabatic potential energy matrix corresponding to the excited states can be written as... 

One can see that the dressed potential energy matrix elements of Eq. (7.24) have the same form than the field-free diabatic potential energy matrix elements of Eq. (7.4). Thus, analytical expressions for the positions and energies of the minima of the dressed upper adiabatic PES and MECI can be obtained by replacing Ej by... 

Nanofibrillar chitin hydrogels are biodegradable, biocompatible, and nontoxic, and thus show promise for biomedical applications. The protonation of amino groups on the surface of chitin allows its application in wound dressings due to the antimicrobial properties of cationic gels [130]. Polymeric fibers that mimic the structure and function of the extracellular matrix are also of interest in tissue engineering and cell culture. Chitin nanofibers can promote cell attachment and show potential as extracellular matrix mimics [29, 125]. 

The UV-cured film of IV-vinyl p30 rolidone has been used as a potential bioadhesive wound-dressing matrix when blended with other polymeric materials. Skin covers and wound dressings made of PVA and PVP were produced with or without polysaccharides by the help of the gamma irradiation technique. Because of its biocompatibility and nontoxicity, PVP was also chosen as the base material for a drug-loading device. Drug release from such membrane was found to depend on the crosslinking density, composition, and membrane thickness. On the other hand, PVP has been used as a carrier in electrospun fiber applications. 

The formulation (10) demonstrates that the coupled motion of electrons and nuclei can be reduced to the study of nuclear motion in the matrix potential V. The impact of the coupling on the electronic motion has been transferred to the dressed kinetic energy operator, which now reads —(1/2M)(V +F), instead of -(1/2M)V for the bare nuclei.
