TL;DR: The oxidation-controlled synthesis of the ytterbium amides and the first rare-earth-metal guanidinates YbC(NH)3 and Yb(CN3H4)3 from liquid ammonia are reported and the IR spectra of the guansidinates are compared with DFT-calculated phonon spectra to identify the vibrational modes.

TL;DR: In this paper, a new class of compounds containing the unsubstituted guanidinate anion CN3H4 has been derived based on powder X-ray diffraction.

TL;DR: The dry weight per unit biovolume of 810 single, living cells of the ubiquitous soil algae Klebsormidium flaccidum from 80 experiments were determined using a Mach–Zehnder double-beam interference microscope to show that C/ubv is suitable to quantify environmental stress conditions.

TL;DR: The herein presented neutron powder-diffraction data support the conjectured sequence of transitions from the high-temperature one-dimensional resonating valence-bond (RVB) state to a transient two-dimensional RVB state and eventually, at lowest temperatures, into another two- dimensional RVBState, presumably the ground state.

TL;DR: This paper introduces a novel approach to Rietveld refinements of two-dimensional angular- and wavelength-dispersive powder diffraction data as measured at time-of-flight neutron diffraction instruments.
