Congo red (CR) dye molecules self-associate in water solutions creating ribbon-like supramolecular structures that can bind various aromatic compounds by intercalation, forming mixed supramolecular systems. Mixed supramolecular systems, such as CR-doxorubicin and CREvans blue, interact with the surface of carbon nanotubes, leading to their stiffening and ultimately to their breaking and shortening. This work presents a simple method of obtaining short and straight carbon nanotubes with significantly better dispersion in aqueous solutions and consequently improved usability in biological systems.

Gmina Sułów jest gminą wiejską. Sąsiedztwo Roztoczańskiego Parku Narodowego, Szczebrzeszyńskiego Parku Krajobrazowego, zbiornik wodny "Nielisz", duże kompleksy leśne przyciągające w sezonie letnim znaczną ilość turystów są czynnikiem przemawiającym za ochroną naturalnych walorów przyrodniczych.

An essential development is presented of our new method of quantitative estimation of the energetic heterogeneity of adsorbent and catalysts surfaces from Temperature Programmed Desorption spectra, based on the Statistical Rate Theory of Interfacial Transport. That method, presented in a series of our recent publications, involved a necessity of estimating, in other than TPD experiments, of certain adsorption parameters which are necessary to calculate the adsorption energy distribution. This was a serious inconvenience of that new method. In this paper, it is shown for the first time, that these parameters can be determined in the same TPD experiment by applying variable heating rate.
