Potassium Diffusion in Mono‐ and Bi‐Crystalline SrTiO3 – Mechanisms and Activation Energies

Advanced Materials Interfaces
The diffusion of potassium in SrTiO3 (STO) single crystals is investigated as a function of temperature. Charge attachment induced transport experiments are employed inducing diffusion profiles in STO evolving with time. Potassium concentration profiles,

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Hyperloop-like diffusion of long-chain molecules under confinement

Nature Communications, 2023
The ultrafast transport of adsorbates in confined spaces is a goal pursued by scientists. However, diffusion will be generally slower in nano-channels, as confined spaces inhibit motion.

Aerosol transport and diffusion data [PDF]

Proceedings of the 17th conference on Winter simulation - WSC '85, 1985
Various mathematical modeling approaches have been developed over the years to simulate the transport and diffusion of small particle aerosols in the atmosphere. The roles played by some important factors/mechanisms are briefly discussed, including the mean and turbulent components of the wind field, boundary conditions, particle size distribution ...
