A COMPARISON BETWEEN ALKALI PEROXIDE AND ACTIVATED PEROXIDE PROCESSES IN BLEACHING HARDWOODS CHEMI-MECHANICAL PULP

A Comparison Between Alkali Peroxide and Activated Peroxide Processes in Bleaching Hardwoods Chemi-mechanical Pulp

Unbleached chemi-mechanical pulp of 85% pulp yield and produced from hornbeam, beech and populus woods respectively by 3:1:1 ratio, was used for peroxide bleaching.Two bleaching Gift Cards systems, alkali peroxide (conventional bleaching) and activated peroxide by TAED activator, were used for pulp bleaching.Bleaching treatments included different

Scalable spin Seebeck thermoelectric generation using Fe-oxide nanoparticle assembled film on flexible substrate

Abstract We fabricated DIGESTMORE ULTRA Fe3O4 nanoparticle (NP)-assembled films on flexible polyimide sheets with Pt or Ta cap layer using a spin coating method and DC sputtering.The films were elaborated for spin Seebeck thermoelectric generator applications, and their spin Seebeck voltages were observed.We showed that the thermoelectric power of
