Nano-dynamic mechanical analysis

Dynamic mechanical analysis is done by researchers to analyze the viscoelastic properties of polymer nanocomposites [3,73,80]. Omrani et al. studied the influence of nano-alumina on the viscoelastic properties of epoxy in... 

Thermal analysis (TA) comprises a family of measuring techniques that share a common feature they measure a material s response to being heated or cooled (or, in some cases, held isothermally). The goal is to establish a connection between temperature and specific physical properties of materials. The most popular techniques are those that are the subject of this book, namely differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), thermomechanical analysis (TMA), dynamic mechanical analysis (DMA), dielectric analysis (DEA), and micro/nano-thermal analysis (p/n-TA). 

The same increase in the glass transition temperature that can be achieved by increasing the curing temperature can also be realised by adding (nano)fillers Dynamic mechanical analysis can be used to compare an unfilled epoxide film, a film filled with 10% pyrogenic silica, a film filled with io% pyrogenic silica that has been silanised with an exocyclic epoxide and a film filled with io% pyrogenic silica that has been silanised with an endocyclic epoxide. 

Abbreviations DSC, differentiai scanning caiorimetry DMA, dynamic mechanical analysis TGA, thermogravimetric analysis DTGA, differential thermogravimetric analysis RVA, rapid viscoanalyser DVS, dynamic vapour sorption ITC, isothermal titration calorimetry DSM/NC, differential scanning micro/nano-calorimetry. 

This chapter reviews recent studies on energy levels and excited state dynamics of lanthanides (R) in nano-structures, which include R-doped dielectric nano-crystals, implanted nano-particles of semiconductors, coated core-shell nano-particles, nano-tubes and nano-balls stuffed with R ions. New phenomena such as the action of confinement on ion-phonon interaction and its consequences for electronic transitions, energy transfer, and phase transitions are discussed in the light of experimental and theoretical studies reported in the literature. Although the review aims at being comprehensive and covers all the important aspects in the field, emphasis is given to identification and theoretical analysis of various mechanisms for...
