H 2020 Project: »RESYNTEX - A new circular economy concept: from textile waste towards chemical and textile industries feedstock« Project Technical Manager and Member of RESYNTEX Coordination team: Aleksandra Lobnik Partners: 20 partners; IOS, Institute for environmental protection and sensors, Ltd (co-coordinator) RESYNTEX is a research project which aims to create a new circular economy concept for the textile and chemical industries. Through industrial symbiosis, it aims to produce secondary raw materials from textile waste. The RESYNTEX project will: a) Create a strategic design for a complete value chain from textile waste collection through to the generation of new feedstock for chemicals and textiles; b)Improve collection approaches and increase public awareness of and social involvement with the issue of textile waste; c) Enable traceability of waste processing using data aggregation. The collected data will evaluate the performance of the new value chains by means of a life cycle assessment (LCA) and life cycle costing (LCC), compared to existing end-of-life scenarios; d) Develop innovative business models for the chemical and textile industries; e) Demonstrate a complete reprocessing line for basic textile components, including liquid and solid waste treatment. Duration: 1.6.2015 – 30.11.2018

COBISS.SI-ID: 20615958Patent invention belongs to the field of processes for preparing conductive Ag/PANI nanocomposites using functional alkoxysilanes as capping agents. This process allows formations of nanostructures of homogenous sizes and morphology with conductive characteristics in range between 0,02 and 0,003 S/cm, with process being performed at low reaction temperatures and with use of environmentally friendly chemicals. Compared to so far known preparation processes, this process differs from them, that the preparation process involves synthesis of silver nanoparticles with new agent for limiting growth and that silver nanoparticles are homogenously distributed through polymer matrix, as polymerization in acidic medium occurs simultaneously with silver nanoparticles incorporation thus improving its conductivity.

COBISS.SI-ID: 20419606The present invention belongs to the field of processes for preparing nanostructures, more precisely to the field of processes for preparing homogeneous superparamagnetic hollow spherical nanostructures with a porous shell based on iron oxide. The technical problem, which is solved by the present invention, is the design of a process for preparing hollow magnetic spherical nanostructures based on coating of solid silicon dioxide cores with magnetic nanoparticles of iron oxide in a spinel crystal structure and formation of hollow spheres using appropriate buffer solutions. The essence of the process for synthesis of superparamagnetic hollow spherical nanostructures is that it includes adsorption of Fe 2+ /Fe 3+ ions onto the surface of mono-dispersed silicon dioxide (SiO 2 ) solid-templates, pre-prepared by the Stöber process, and dissolution of SiO 2 solid-templates by the use of basic aqueous solutions of [2OH - / HCO 3 - ] ions and [CO 3 2- /HCO 3 - ] ions having pH value between 7 and 12, and reaction of precipitation of Fe 2+ /Fe 3+ ions in the form of superparamagnetic spinel iron oxide nanoparticles. Thus obtained superparamagnetic hollow spherical nanostructures enable responsiveness and manoeuvrability of the whole nanostructure using external magnetic field, as well as the local release of loaded active substances due to the porosity of the superparamagnetic shell.
