Advanced Functional Materials, EarlyView.The negative electron affinity of diamond allows to emit highly reductive electrons. By introducing intra‐bandgap states and an optimized electron transfer mechanism by surface functionalization with Ru(bpy)3, the formation of solvated electrons is achieved upon solar irradiation.

Symmetry, Integrability and Geometry: Methods and Applications, 2009 Cartan's method of moving frames is briefly recalled in the context of immersed curves in the homogeneous space of a Lie group $G$. The contact geometry of curves in low dimensional equi-affine geometry is then made explicit.

Advanced Functional Materials, EarlyView.Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Finite Geometry Behind the Harvey-Chryssanthacopoulos Four-Qubit Magic Rectangle
, 2012 A "magic rectangle" of eleven observables of four qubits, employed by Harvey and Chryssanthacopoulos (2008) to prove the Bell-Kochen-Specker theorem in a 16-dimensional Hilbert space, is given a neat finite-geometrical reinterpretation in terms of the ...

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)
Advanced Functional Materials, EarlyView.Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Advanced Functional Materials, EarlyView.A polyelectrolyte complex‐based sorbent is produced by scalable, environmentally benign aqueous phase inversion. Its porous, LiCl‐ and GO‐integrated architecture enables hourly adsorption−desorption cycles at low relative humidity (RH < 30%). A large‐scale prototype achieves multicyclic, solar‐driven atmospheric water harvesting of 1.37 L kg−1 day−1 ...

Mechanoregulatory Effects of Cell‐Scale Microwells on Epithelial Cell Phenotype
Advanced Functional Materials, EarlyView.In small polycaprolactone microwells, A549 epithelial cells span well edges, in contrast to cells growing on flat substrates. Focal adhesion sites (yellow) concentrate at topographic boundaries, while cytoskeletal tension (magenta stress fibers) is transmitted to the nucleus (blue), reducing nuclear sphericity.

Nonsingular, Lump-like, Scalar Compact Objects in (2 + 1)-Dimensional Einstein Gravity
UniverseWe study the space-time geometry generated by coupling a free scalar field with a noncanonical kinetic term to general relativity in (2+1) dimensions. After identifying a family of scalar Lagrangians that yield exact analytical solutions in static and ...

Advanced Functional Materials, EarlyView.Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.
