Venäjä, Ukraina ja sumea länsi: Banaali oksidentalismi Helsingin Sanomissa

2015

Analysoin artikkelissani Helsingin Sanomien pääkirjoitusaukeaman tekstejä vuodelta 2014 ja selvitän, millaisen kuvan ne rakentavat länsimaista. Pohdin myös, millä tavalla Ukrainan kriisi ja Venäjän osallisuus siinä osaltaan vahvistavat näkemystä länsimaista kaikessa heterogeenisuudessaan yhtenäisenä toimijana. Artikkelini osoittaa, että maantieteellisestä laajuudestaan ja poliittisesta epäyhtenäisyydestään huolimatta (tai sen vuoksi) länsimaat on hyvä esimerkki Benedict Andersonin ja Michael Billigin kuvailemasta median, sananvalintojen ja pienten arkipäiväisten käytäntöjen avulla ylläpidetystä kuvitellusta yhteisöstä. Se on yhteisö, jonka olemassaololle on tärkeää, että siihen uskotaan ja …

Modification of the Selectivity Properties of Tubular Ceramic Membranes after Alkaline Treatment

2017

International audience; This work focuses on the selectivity modification of ceramic membranes after a mild alkaline treatment. Filtration of pure saltwater solutions was carried out with commercial titania membranes before and after the treatment. After treatment, the rejection of NaF significantly decreased, while the rejection of NaCl and NaBr increased. Additionally, NaI and Na 2 SO 4 remained close to zero. Pore size and electrical charge being almost unchanged, only significant modifications in the dielectric effects can explain this modification of selectivity. Therefore, the surface chemistry and the interaction (nature and magnitude) with the solvent and with the species present in…

State selective electron injection in non-aggregated titanium phthalocyanine sensitised nanocrystalline TiO2 films

2004

We describe a novel titanium phthalocyanine that shows no aggregation when anchored to nanocrystalline TiO2 films through its axial carboxylated ligand without the use of co-adsorbents; state selective electron injection into the TiO2 is demonstrated, resulting in efficient photocurrent generation in dye sensitised photoelectrochemical solar cells.
