6,6-dimethylbicyclo[3.1.1]heptan-2-one, (1R)-(+)-nopinone, is a liquid at room temperature. It solidifies below 260 K to form an orientationally disordered body-centred cubic phase (a = 7.644 Å at 255 K), which transforms to an ordered structure below 240 ...
The thermal decomposition of three synthetic copper sulfides (chalcocite (Cu2S), chalcopyrite (CuFeS2), and enargite (Cu3AsS4)) and two commercial copper concentrates has been studied on a thermobalance (T = 1173-1773 K) and an imaging furnace (T approxima ...
The formation of LiBD4 by the reaction of LiD in a diborane/hydrogen atmosphere was analysed by in situ neutron diffraction and subsequent microstructural and chemical analysis of the final product. The neutron diffraction shows that nucleation of LiBD4 al ...
We have solved and refined the crystal structure of the orthorhombic gamma-phase of Ca(BD4)(2) by combined synchrotron X-ray powder diffraction, neutron powder diffraction, and ab initio calculations. Among five structural candidates giving the same qualit ...
A strong Kohn anomaly in ZrTe3 is identified in the mostly transverse acoustic phonon branch along the modulation vector q(P) with polarization along the a(*) direction. This soft mode freezes to zero frequency at the transition temperature T-P, and the te ...
This thesis investigates nine new compositions of the ternary Au-Cu-Pt system, containing from 75 to 78 wt% Au with 0 to 15 wt% Pt, by means of in-situ synchrotron radiation X-ray diffraction, differential scanning calorimetry, transmission electron micros ...
Ferroelectric perovskites exhibit superior dielectric, piezoelectric and ferroelectric properties. Architecting ferroelectrics in the small scale holds interest in both application and fundamental research. Compared to their 2D counterparts – thin films, f ...
This study focuses on the application of infra-red thermography to visualise the heat transfer dynamics of diabatic flows in multi-microchannels etched into silicon wafers. The 100 parallel channels were 50 micron wide, 100 microns deep, and with a pitch o ...
The signature of the strong-coupling regime is unambiguously evidenced in a GaN-based microcavity (MC) above the polariton lasing threshold P-thr at room temperature through the observation of the upper polariton branch. The MC system exhibits a renormaliz ...
The spin- and charge-density-wave order parameters of the itinerant antiferromagnet chromium are directly measured with nonresonant x-ray diffraction as the system is driven toward its quantum critical point with high pressure using a diamond anvil cell. T ...
