Understanding the White-Emitting CaMoO4 Co-Doped Eu3+, Tb3+, and Tm3+ Phosphor through Experiment and Computation

2019

In this article, the synthesis by means of the spray pyrolysis method, of the CaMoO4 and rare-earth cation (RE3+)-doped CaMoO4:xRE3+ (RE3+ = Eu3+, Tb3+, and Tm3+; and x = 1, 2, and 4% mol) compounds, is presented. The as-synthesized samples were characterized using X-ray diffraction, Rietveld refinement, field emission scanning electron microscopy (FE-SEM), Raman spectroscopy, and photoluminescence (PL) spectroscopy. To complement and rationalize the experimental results, first-principles calculations, at the density functional theory level, have been performed to analyze the band structure and density of states. In addition, a theoretical method based on the calculations of surface energie…

Some Remarks about Product Spaces

2018

Summary This article covers some technical aspects about the product topology which are usually not given much of a thought in mathematics and standard literature like [7] and [6], not even by Bourbaki in [4]. Let {Ti}i∈I be a family of topological spaces. The prebasis of the product space T = ∏ i∈I Ti is defined in [5] as the set of all π −1 i (V) with i ∈ I and V open in Ti . Here it is shown that the basis generated by this prebasis consists exactly of the sets ∏ i∈I Vi with Vi open in Ti and for all but finitely many i ∈ I holds Vi = Ti . Given I = {a} we have T ≅ Ta , given I = {a, b} with a≠ b we have T ≅ Ta ×Tb . Given another family of topological spaces {Si}i∈I such that Si ≅ Ti fo…

The activation of aggresomal pathway in Coxsackievirus B3 infection

2016

Aggresomin muodostuminen on yksi solun puolustusmekanismeista, joka pyrkii estämään proteiinien haitallisen aggregoitumisen solulimassa. Aikaisemmat kokeet ovat näyttäneet, että ihmisen enterovirus-infektio aiheuttaa muutoksia vimentiinissä, tyypin III välikokoisessa filamentissa (Turkki et al., julkaisematon data). Nämä muutokset ovat hyvin samankaltaisia aggresomin muodostumisen aikana tapahtuvien muutoksien kanssa. Tämän tutkimuksen tarkoituksena oli selvittää mahdollisen aggresomin muodostumisreitin aktivoituminen Coxsackievirus B3 (CVB3) -infektiossa, ja hypoteesimme oli, että häkkimäisten vimentiinirakenteiden muodostumisen lisäksi myös muita aggresomin muodostumisreitin aktivoitumise…
