We report a new complex Eu(tta)(3).bpt (tta = thenoyltrifluoroacetonate; bpt = 2-(N,N-di-ethylanilin-4-yl)-4,6-bis(pyrazol-1-yl)-1,3,5-triazine) with excellent long-wavelength sensitized luminescent properties, in which four hydrogen atoms replace the methyl groups at the 3,3'- and 5,5'-positions of the pyrazolyl rings in a previously reported complex Eu(tta)(3).dpbt. Upon visible-light excitat...

The era of “permacrisis” gives rise to minilateral arrangements increasingly at the expense embedded multilateralism in regional governance. area Indo-Pacific has become bedrock security cooperation. 2022 Joint Declaration on Security Cooperation (JDSC) between Japan and Australia compliments hub-and-spokes system poses an opportunity for European Union advance its own strategic compass address...

The both Atlantic side relations from the ancient time had been faced with too much challenge but the continuing of this relation is due to the common political and economical interests. The upper Atlantic and the two organizations (NATO, EU) still exist to gain the essential goals and the political and security connection which are boosting with the economical integration at the same time. But...

Layered oxides intercalated with Eu ions were prepared by self-assembly deposition method based on the electrostatic interaction between negative charged oxide nanosheets and Eu ions. The layered oxides were composed of two-dimensional host nanosheet layer with guest Eu ions and gave Eu emission based on an energy transfer from bandgap excitation of the host oxide nanosheets to the Eu ions. The...

Opioid dependence, despite being the subject of significant public funding, remains a costly burden to Australian society in human and economic terms. The most cost-effective public health strategy for managing opioid dependence is opioid substitution therapy (OST), primarily through the use of methadone or buprenorphine. Supervised dispensing of OST from specialist clinics and community pharma...

the european :union: in its policy declarations states that the respect for human rights is a requirement in its internal and external relations. for instance, accession of european countries to the :union:, enjoying its services, and even signing an agreement with non-members is dependent on the observation of human rights. in this paper, the position of human rights in the european :union: le...

Forced migration has become a world-wide phenomenon in the past century, affecting increasing numbers of countries and people. It entails important challenges from a global health perspective. Leppold et al have critically discussed the Japanese interpretation of global responsibility for health in the context of forced migration. This commentary complements their analysis by outlining three pr...

The sharp increase in the number of new COVID-19 cases late 2021 and early 2022, which is associated with spread a strain coronavirus - omicron great concern makes it necessary to make at least approximate forecasts for pandemic dynamics epidemic. As this rapid growth occurs even countries high levels vaccinations, question arises as their effectiveness. smoothed daily deaths per capita ratio t...

The mixed valence europium nitridosilicate Eu(2)SiN(3) has been synthesized at 900 degrees C in welded tantalum ampules starting from europium and silicon diimide Si(NH)(2) in a lithium flux. The structure of the black material has been determined by single-crystal X-ray diffraction analysis (Cmca (no. 64), a = 542.3(11) pm, b = 1061.0(2) pm, c = 1162.9(2) pm, Z = 8, 767 independent reflections...
