Effect of the morphology on the optical and electrical properties of polycarbonate film doped with aniline derivatives monomers
In this paper we present some comparative studies between the optical and electrical properties of the films prepared by vacuum evaporation from amidic monomeric compounds obtained from maleic anhydride and aniline derivative with different functional groups [CN; NO2], and the composite films prepared by spin-coating from a polycarbonate of bisphenol A matrix embedding clusters of these amidic monomers. We have emphasised the effect of the polymeric matrix on the properties of the synthesised monomers with the purpose to change the physical properties of the films (optical transmission, luminescence, electrical conduction, optical non-linear phenomena). The correlation between the morphology of the films and the optical and electrical properties has also been investigated
Ground Failure and Remedial Measures at a Block of Flats
Thee ground failure presented in the paper, occurred in 1986, in the foundation ground, of a ten storyed block of flats, consisting of Bahlui structured dilatant clay, normally consolidated. The foundation ground rupture, by plastic yielding, begin shortly after an accidental drowning of the basement. Before this accident, the building had not presented any signs of evolutive settlements processes. The paper presents the consolidation measures taken to stop the progressive yielding of the ground beneath the foundations. Results of tests pointed out the dilatant behavior and the sensitivity to moistening of the Bahlui clays, during the shear process

Effect of maleic anhydride–aniline derivative buffer layer on the properties of flexible substrate heterostructures: Indium tin oxide/nucleic acid base/metal
This paper presents some investigations on the properties of guanine (G) and cytosine (C) based heterostructures deposited on flexible substrates. The effects of two types of maleic anhydride–aniline derivatives (maleic anhydride-cyano aniline or maleic anhydride-2,4 dinitroaniline) buffer layer, deposited between indium tin oxide and (G) or (C) layer, on the optical and electrical properties of the heterostructures have been identified.The heterostructures containing a film of maleic anhydride-2,4 dinitroaniline have shown a good transparency and low photoluminescence in visible range. This buffer layer has determined an increase in the conductance only in the heterostructures based on (G) and (C) deposited on biaxially-oriented polyethylene terephthalate substrate
