Argon plasma treatment followed by exposure to atmospheric oxygen has been used to introduce new carbon–oxygen functionalities to polymer surfaces. We report on the treatment of poly(styrene) (PS), low density poly(ethylene) (LDPE), poly(propylene) (PP) and poly(ethylene terephthalate) (PET). Argon plasma-treated poly…

Recent progress concerning lattice dynamics in quasicrystals, both theoretical and experimental, is discussed. The theory deals with the general description, which differs from that for ordinary crystals, and with model calculations and rigorous results for one-, two-, and three-dimensional systems. Experimental resul…

Pinning of the ferroelastic-ferroelectric domain walls on randomly distributed defects in ferroelectric ceramics leads to a field dependence of the piezoelectric coefficient that is analogous to the Rayleigh law for magnetic susceptibility. It is shown in this paper that the piezoelectric coefficient of a lead zircona…
