Abstract This review is devoted to recent progress in the design of anticancer drug delivery systems with participation of unique polysaccharide gellan gum. At first a brief literature survey on conformational and phase behavior of gellan gum as a function of external stimuli, such as temperature, pH, salt addition etc. is presented. Then the immobilization protocol of anticancer drugs and gold nanoparticles within gellan-based hydrogel matrix is discussed. Release of anticancer drugs from gellan gel matrix to outer solution is considered. Cytotoxicity of gellan gum-immobilized gold nanoparticles together with their anticancer activity is summarized.

   JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Opinion The flexible microwave absorbers are being considered as new generation materials which have wide applications in the local area network, wireless data communication, radar systems, satellite communication, satellite television, electronic devices and the heating systems, etc. A number of dielectric, magnetic, and magneto – dielectric materials are frequently used as microwave absorbers for various applications. The carbonaceous materials like carbon fiber, carbon nanotubes, graphite and graphene and inorganic materials like metals, metal oxides, and conducting alloys are used to develop the dielectric microwave absorber because of their conducting loss property. The magnetic materials like magnetic metals and their compounds are used to produce magnetic microwave absorber due to their hysteresis loss property. The combined features of the dielectric and magnetic materials together assist in the preparat...

       JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract A very simple experiment shows students the difference between primary and secondary molecular binding forces. Use an empty plastic cup for milk, yoghurt or coffee and destroy it by pressing the cup together. You will watch cracks only longitudinal the cup. Try to break the cup horizontally you will fail. What you observe are the secondary binding forces between the molecules oriented along the length of the cup versus the primary binding forces perpendicular to the long side of cup. Keywords:  Molecular Binding Forces; Recycling/Reuse; Life Cycle Engineering (LCE) Introduction What should be found/investigated ? [answer: Are the primary molecular binding forces (within the molecular chain acting binding forces, i.e. between primarily connected atoms) actually significantly stronger than the secondary binding forces (between molecules acting forces)? How can a yoghurt cup be reused in...
