Origin of phase relative stability and phase transformation in an S‐ibuprofen–nicotinamide cocrystal

open access: yesActa Crystallographica Section C, EarlyView.
The crystal structure of the metastable form of S‐ibuprofen–nicotinamide cocrystals was solved from powder X‐ray diffraction data and explains the main mechanisms responsible for the relative stability of the two forms of the cocrystals. This also made it possible to explain the transition mechanism between the two forms with temperature.The crystal ...

Non-Abelian spin Hall insulator

open access: yesPhysical Review Research
Motivated by a recent experiment reporting the fractional quantum spin Hall effect in twisted MoTe_{2}, we investigate microscopically the prospects of realizing exotic topologically ordered states beyond conventional quantum Hall physics. We show that a

The simplicity of physical laws

open access: yesNoûs, EarlyView.
Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
