One of the first tension resistant materials that is used to build structures is wood. It is highly anisotropic material. The strength of wood in the fiber direction is relevant for dimesioning. From the economic point of view necessity of strengthening the damaged wooden structures is questionable. Given that this is a light material, suitable for...

The changes of optical properties under boundary presence in molecular crystal nanofilm were theoretically investigated in this work. The dispersion law and states of excitons as well as their space distribution along boundary direction have been determined using adjusted Green’s function method and also by combined analytical and numerical c...
