The low-temperature phase transitions of thermoelectric Zr 4 Sb 3 have been characterized using singlecrystal X-ray diffraction, electrical resistance, and thermal conductivity measurements. Room-temperature stable, disordered β-Zn 4 Sb 3 undergoes a phase transition at 254 K to ordered α-n 4 Sb 3 , which has an ideal composition Zn 4 Sb 10 . Below 235 K, a second low-temperature phase (α′-Zn

Two series of [(Ln1/3Sr2/3S)1.5]1.15NbS2and (Ln1-xSrxS)1+yNbS2misfit layer sulfides have been synthesized and studied by X-ray powder and single crystal diffraction, electron diffraction, and EDX-analysis. The [(Sm1/3Sr2/3S)1.5]1. 15NbS2compound belongs to the 1.5Q/1H homologue type where the Sr-cations are mainly located at the exterior of the Q-slab whereas Sm preferably occupy the positions at

The title compounds were synthesized from MoCl2 and the appropriate commercial chlorides and their structures were solved by a combination of single crystal X-ray diffraction analysis and theoretical methods. The NH4, K and Rb compounds are essentially isostructural, and crystallize in space group Ia (No. 9) with the cell parameters (in Å) a=9.173(1), b=14.986(2), c=17.505(3), β=92.94(2)°(NH4); a=

The copper vanadium oxide bronze Cu2.33-xV4O 11 exhibits a three part composite structure refined on the basis of XRD low-temperature studies. It crystallizes in the triclinic system with the non-centric superspace group X1 and cell parameters a=15.280(3)Å; b 1=3.616(1)Å; c=14.674(3)Å; α=90.0°; β=101.95(3)°; γ=90.0° with a modulation q-vector equal to (0,0.11,0). The three different parts of this

Synthesis, X-rays, TEM and HREM studies of the composition x = 0.25 of the solid solution Sb2W1-xMoxO6 are reported. The phase crystallises in the monoclinic system, space group C2 and the cell parameters of its average structure are a = 11.1296(6) Å, b = 9.8868(9) Å, a = 18.501(2) Å, and β = 96.951(9)°. Mo and W atoms are ordered in the 1/3 ratio. Twining and extended defects have been studied by

Purpose: The purpose of this paper is to explore if a ringing cell phone could impact cognitive performance as well as being agitating to provoke aggressive reactions. The study investigated variables that could impact a participant’s willingness to aggress and retaliate, such as sensitivity to arousal and dark personalities (DRPs), Machiavellianism, narcissism, and subclinical psychopathy and sad

DN DEBATT 15/3. Sedan industrialiseringens början har vi använt omkring fyra femtedelar av den mängd fossilt kol som får förbrännas för att vi ska klara Parisavtalet. Vi har bara en femtedel kvar och det är bråttom att kraftigt reducera utsläppen. Det har Greta Thunberg och de strejkande ungdomarna förstått. Därför stödjer vi deras krav, skriver 270 klimatforskare.

The aim of the present study is to examine and describe Swedish upper secondary students’ use of their background languages while translating a text from Italian, a language unknown to them, into either their L2 English or their L3 French or Spanish. The assumption here is that searching for similarities between these languages is a natural feature of language learning and that intercomprehension

Climate change has made urban decarbonisation a global imperative. Cities are both a source of emissions and a leverage-point for the necessary transformation processes. Iceland is blessed with an ample supply of renewable energy sources. Hydropower and geothermal are widespread in the country and they dominate the country’s electricity and district heating systems. Despite this huge potential, pe

Background: Inadequate stores or intakes of essential minerals in pregnancy, or too high exposure to both toxic and essential elements, can have adverse effects on mother and child. The main aims of this study were to 1) describe the concentrations and patterns of essential and toxic elements measured in maternal whole blood during pregnancy; 2) identify dietary, lifestyle and sociodemographic det

The crystal structure of the phase Ce6Cd37 was determined by single-crystal X-ray diffraction. It is closely related to, and indeed probably identical to, the previously reported compound CeCd6. The compound crystallizes in the centrosymmetric space group Pn3̄ with the unit cell axis 15.808(2) angstrom. The structure may be described by successive shells centered around the origin and the position

OBJECTIVE To investigate real-world costs of continuous insulin pump therapy compared with multiple daily injection (MDI) therapy for type 1 diabetes. RESEARCH DESIGN AND METHODS Individuals with type 1 diabetes and pump therapy in the Swedish National Diabetes Register (NDR) since 2002 were eligible. Control subjects on MDI were matched 2:1 using time-varying propensity scores. Longitudinal data

The text casts doubt on the utility of proportionality tests to resolve conflicts between peremptory norms of public international law with reference to an argument advanced by João Ernesto Christófolo. Responding to Christófolo, the text maintains that subjecting conflicts between peremptory norms to a proportionality analysis entails judicial law-making, does not safeguard the interests protecte

Introduction Including the patient perspective is important to achieve optimal outcomes in the treatment of rheumatoid arthritis (RA). Ample qualitative studies exist on patient outcomes in RA. A Belgian study recently unravelled what matters most to patients throughout the overwhelming and rapidly evolving early stage of RA. The present study, European Qualitative research project on Patient-pref
