Interplay of thermal diffuse scattering and correlated compositional disorder in KClBr.

Single-crystal X-ray diffuse scattering measurements are reported of the compositional series KClBr, a model system for the broader family of disordered rocksalts. Using a combination of Monte Carlo simulations and lattice dynamical calculations, we show that the observed diffuse scattering is well described in terms of (i) non-statistical anion distributions, (ii) local lattice relaxations accompanying Cl/Br substitution, and (iii) the contribution from low-energy phonons. It is found that a tendency for compositional domain formation broadens the thermal diffuse scattering by splitting and softening the acoustic phonon branches.

Managing diabetes and hypertension in chronic kidney disease.

Since 2020, several guidelines have been published to help health practitioners better manage hypertension and diabetes in patients with chronic kidney disease. Scrutiny on the inclusion of race in determining the estimated glomerular filtration rate (eGFR) as well as breakthrough research regarding the drug dapagliflozin for the treatment of patients with chronic kidney disease are discussed.
