Closing Gaps in Geometrically Frustrated Symmetric Clusters: Local Equivalence between Discrete Curvature and Twist Transformations

Mathematics, 2018
In geometrically frustrated clusters of polyhedra, gaps between faces can be closed without distorting the polyhedra by the long established method of discrete curvature, which consists of curving the space into a fourth dimension, resulting in a ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Twist-Dependent Electronic Coupling in an Organic Intervalence Radical Cation

, 2016
The nearly 90° twist between the reduced dialkylaniline π system and the oxygen atom p lone pair orbital limits electronic interaction between the reduced and oxidized aniline units and makes varying this twist angle a principal factor that facilitates ...

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

FEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Influence of the Twist Angle and Spin–Orbit Coupling on the Interlayer Coupling and Optoelectronic Properties of MoS2/WS2 Superlattice Heterostructures

Advanced Electronic Materials
Twisted 2D bilayer transition metal dichalcogenides (TMDs) heterostructures exhibit rich physical properties due to the interaction of interlayer coupling and moiré superlattice effects.

Tunable Chiral Spectral Responses of Incommensurate Twisted Bilayer Photonic Crystals

Applied Sciences
Recently, twisted bilayer photonic crystals (TBPhCs) have been used as moiré-based optical platforms, supporting twist-tunable chiroptical and polarization-dependent responses. A periodic moiré supercell exists only for commensurate twist angles, whereas

Flexural Behavior of 3D‐Printed Porous Bouligand‐Structured Polymers: Influence of Pitch Angle and Porosity

Advanced Engineering Materials, EarlyView.
This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight
