The Effect of Hydrophilic Headgroup Chemistry on Peptoid‐Directed Mineralization of CaCO3

open access: yesAdvanced Functional Materials, EarlyView.
Amphiphilic peptoids alter the pathway and outcome of calcium carbonate crystallization, which progresses through amorphous calcium carbonate (ACC) to vaterite to calcite rhombs in the absence of peptoids. In contrast, amine‐terminated peptoids produce vaterite disks and carboxyl‐terminated peptoids produce calcite mesocrystals.

Unexpected Asymmetric Mn‐Sb Site Mixing and Reentrant Spin‐Glass State of MnSb2Te4

open access: yesAdvanced Functional Materials, EarlyView.
MnSb2Te4 is an intrinsic magnetic topological insulator. Its properties are extraordinarily sensitive to tiny defects, making structural studies essential for understanding how magnetism and topology work together. This work shows that Mn can be unevenly distributed within the crystal and how that disorder is linked to a newly reported spin‐glass state

Chemical Constituents from Licania cruegeriana and Their Cardiovascular and Antiplatelet Effects

open access: yesMolecules, 2014
Three new lupane-type triterpenoids: 6β,30-dihydroxybetulinic acid glucopyranosyl ester (4), 6β,30-dihydroxybetulinic acid (5) and 6β-hydroxybetulinic acid (6), were isolated from Licania cruegeriana Urb. along with six known compounds.

Orbital Engineering through Strain‐Induced Spin–Orbit–Lattice Coupling in Sr2FeReO6 Double Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
Epitaxial strain drives oxygen‐octahedral reconfiguration in Sr2FeReO6 double‐perovskite thin films, inducing orbital‐selective reconstruction of Re 5d states through modified Fe–O–Re hybridization. This coupled lattice–orbital response enables magnetic easy‐axis reversal and a transition from metallic‐like to semiconducting‐like transport.

Sub‐nm2 Ferroelectric Domains via Charged 180° Walls in ZrO2

open access: yesAdvanced Materials, EarlyView.
Ferroelectric ZrO2${\rm ZrO}_2$ thin films host closely spaced charged 180∘$^{\circ }$ domain walls that vertically compress polar domains beyond their lateral half‐unit‐cell limit. These head‐to‐head and tail‐to‐tail walls show distinct bulk‐like structures, natural oxygen‐mediated stabilization, and highly asymmetric mobility, highlighting new ...

Recital Programming – How Hard Can It Be?

open access: yesArt of Humanistic Management Journal
This essay considers some the important factors when planning organ recital programmes. The crucial first step of acknowleding the type of audience who will be attending. Next, considering and reflecting the style of the organ to be played: is it a large
