“…Wood, tension wood, electrospinning process and tempo mediated oxidation, which is an treatment that uses the chemical compound (2,2,6,6-Tetramethylpiperidin-1-yl)oxy (TEMPO), were also part of the final selection. These themes appears frequently in nanocellulose-focused studies (Azizi Samir, Alloin, & Dufresne, 2005;Charreau, Foresti, & Vazquez, 2013;Chirayil, Mathew, & Thomas, 2014;Dai et al, 2014;Domingues, Gomes, & Reis, 2014;Durán, Lemes, & Seabra, 2012;Eichhorn et al, 2010;Isogai, 2013;Klemm et al, 2011;Moon et al, 2011;Orts et al, 2005;Pääkkö et al, 2007;Siqueira et al, 2010;Siró & Plackett, 2010) Figure 7 presents a map with these research topics (nodes).

Advances concerning publication-level classification system have been demonstrated striking results by dealing properly with emergent, complex and interdisciplinary research areas, such as nanotechnology and nanocellulose. However, less attention has been paid to propose a delineating method to retrieve relevant research areas on specific subjects. This study aims at proposing a procedure to delineate research areas addressed in case nanocellulose. We investigate how a bibliometric analysis could provide interesting insights into research about this sustainable nanomaterial. The research topics clustered by a Publication-level Classification System were used. The procedure involves an iterative process, which includes developing and cleaning a set of core publication regarding the subject and an analysis of clusters they are associated with. Nanocellulose was selected as the subject of study, but the methodology may be applied to any other research area or topic. A discussion about each step of the procedure is provided. The proposed delineation procedure enables us to retrieve relevant publications from research areas involving nanocellulose. Seventeen research topics were mapped and associated with current research challenges on nanocellulose.

“…5 Modul elasti~nosti celuloznih nanofibril je teoreti~no vi{ji od jekla in dosega vrednosti blizu 137 GPa. 6 Natezna trdnost NFC je pribli`no 10 GPa, koeficient termi~nega raztezka pa je nizek in dosega vrednosti blizu 2,6·10 -6 K -1 . [7][8][9][10] Ker so mehanske lastnosti celuloznih nanofibril primerljive z lastnostmi drugih in`enirskih materialov (steklena, aramidna, kevlar vlakna), 5 so primerna oja~itvena sredstva za utrjevanje najrazli~nej{ih polimernih osnov.…”

Namen prispevka temelji na inovativnem postopku izdelave nanokompozitov na osnovi poli(3-hidroksibutirata) (PHB) in nanofibrilirane celuloze (NFC). Raziskovalno delo obravnava pripravo koncentratnih me{anic PHB-prahu in NFC v vodni raztopini za tehnologijo ekstruzijskega me{anja. Ekstrudat koncentrirane me{anice PHB/NFC je bil nato uporabljen kot dodatek h granulirani obliki PHB pri pripravi brizganih vzorcev z razli~nimi ute`nimi dele`i NFC. V prispevku so podane dolo~ene omejitve pri predelavi tovrstnih materialov in predlagane uporabne re{itve za njihovo optimiziranje. Morfolo{ke lastnosti nanokompozitnih komponent smo raziskali z elektronsko mikroskopijo (FE-SEM), mehanske lastnosti pa z nateznim preizkusom. Morfolo{ka preiskava koncentratnih me{anic je razkrila prepleteno sestavo celuloznih nanofibril in polimernih kroglic, prĩ emer se posamezne fibrile prepletajo v obliki {ir{ih pramenov in ustvarjajo videz zamre`ene strukture znotraj polimerne komponente. Mikroskopski posnetki nanokompozitnih me{anic in izbolj{ane mehanske lastnosti izhodnih materialov potrjujejo, da je adhezivni stik med matri~no in oja~itveno komponento dose`en, porazdelitev celuloznih nanofibril po polimerni osnovi pa homogena. Nanokompoziti z visokimi ute`nimi dele`i NFC (10 % ute`nega dele`a) dosegajo pomembno ve~je vrednosti modula elasti~nosti (Et = 1720 MPa) in raztezka pri pretrgu (eb = 3,1 %) ter prenesejo vi{je pretr`ne napetosti (sM = 26 MPa) v primerjavi z referen~nim polimernim vzorcem (Et = 1340 MPa; eb = 2,4 %; sM = 20 MPa). Rezultati {tudije dokazujejo, da je ob pravilni predpripravi polimernih me{anic in optimizaciji tehnologije ekstruzijske predelave, mogo~e izdelati trdne in`ilave materiale, pri~emer dele`oja~itvene faze narekuje stopnjo izbolj{ave kon~nih lastnosti biopolimerne osnove. Klju~ne besede: nanofibrilirana celuloza, poli(3-hidroksibutirat), morfologija, mehanske lastnosti, ekstruzija, tehnologija brizganja In this paper a novel processing route for nanocomposites, based on (3-hydroxybutyrate) (PHB) and nanofibrillated cellulose (NFC), is presented. To obtain a uniform dispersion of the reinforcing filler, a PHB powder was first dispersed in water, mixed with an NFC aqueous suspension and then freeze dried to eliminate the water phase from the ensuing system. The dried batch was then extruded and added to the granulated PHB in different weight proportions. Nanocomposites with various NFC contents were subsequently produced with the injection-moulding technology. The processing limits and feasible solutions for their optimization are thoroughly described within this work. Morphological properties were investigated with FE-SEM, while mechanical properties were determined via a tensile test. SEM images showed that the PHB powder can be effectively incorporated into the mesh of cellulose nanofibrils, as clearly evident by the interlaced structure of individual fibrils with the average lateral dimensions of 69±14 nm. Improved mechanical properties and SEM observations confirmed a good interfacial adhesion and uni...

“…Thermal properties are very important for nanocomposites. Differential scanning calorimetry (DSC), Thermogravimetric analyzer (TGA), and DMA have been used to evaluate thermal properties (Ljungberg et al, 2006;Orts et al, 2005;Samir et al, 2006;Wang et al, 2010).…”
