    Abstract : Popular Abstract in Swedish Många beständighetsproblem uppträder i gränsytor mellan material. Exempel är lossfrysning av puts på tegel, avflagning av färg, sprickbildning hos ytskikt, vidhäftningsbrott mellan reparationsmaterial och underlag. I nästan alla fall är nedbrytningen kopplad till alltför höga fuktnivåer i gränsytan. READ MORE

  4. 4. On the operation of light-emitting electrochemical cells

    University dissertation from Umeå : Umeå Universitet

    Author : E. Mattias Lindh; Umeå universitet.; [2019]
