We present analytical expressions for the 31 five-particle phase-space master integrals in massless QCD as an $\epsilon$-series with coefficients being multiple zeta values of weight up to 12. In addition, we provide computer code for the Monte-Carlo integration in higher dimensions, based on the RAMBO algorithm, that has been used to numerically cross-check the obtained results in 4, 6, and 8 dimensions..

Poly(triazine imide) (PTI) is a materialbelonging to the group of carbon nitrides and has shown tohave competitive properties compared to melon or g-C3N4,especially in photocatalysis. As most of the carbon nitrides, PTIis usually synthesized by thermal or hydrothermal approaches.We present and discuss an alternative synthesis for PTI whichexhibits a pH-dependent solubility in aqueous solutions.

X-ray phase contrast imaging based on free space propagation relies on phase retrieval to obtain sharp images of micro- and nanoscale objects, with widespread applications in material science and biomedical research. For high resolution synchrotron experiments, phase retrieval is largely based on the single step reconstruction using the contrast transfer function approach (CTF), as introduced almost twenty years ago [Cloetens et al., Appl. [...]

The nature of retinal shielding pigment in the larval eyes of the midge Clunio marinus was studied by high resolution scanning X-ray fluorescence (XRF) analysis correlated with light microscopy and scanning coherent X-ray diffractive imaging (Ptychography). Clunio is known as a unique model system to decipher mechanisms underlying the complex moon-related rhythms. [...]
