Advanced Functional Materials, EarlyView.Auxeticity‑by‑Assembly converts freeform photovoltaics from cut‑defined layouts to assembly‑defined systems. Standardized interlocking units generate negative‑Poisson‑ratio, reconfigurable architectures, while hinge regions are wired by selectively activatable AgNW–GO@EGaIn composite interconnects and a folding‑enabled interconnector layer. A decimeter‑

, 2013 A graph G is singular if the zero-one adjacency matrix has the eigenvalue zero. The multiplicity of the eigenvalue zero is called the nullity of G. For two vertices y and z of G, we call (G, y, z) a device with respect to y and z. The nullities of G, G − y, G − z and G − y − z classify devices into different kinds.

Interlacing inequalities. matrix groups
Linear Algebra and its Applications, 1992 This overview consists of two parts. The first part is about the attempt to construct a unifying theory on the interlacing inequalities. The Carlson-Sá theory is the only attempt so far in this direction and it does not say any thing for the sufficient part.

Advanced Functional Materials, EarlyView.The hidden role of Cd segregation at grain boundaries is revealed in p‐type Mg3Sb2 by atom probe tomography and other advanced characterizations. Grain boundary Cd enrichment suppresses the SbMg+ hole‐killer formation and lowers potential barriers, enhancing electrical conductivity.

Assembly of Cell‐Seeded 3D Printed Hydrogel Modules with Perfusable Channel Networks
Advanced Functional Materials, EarlyView.Macroscale assembly was utilized to prepare perfusable tissue constructs from individually 3D printed hydrogel modules with embedded branched channel networks and port arrays for cell seeding. Novel multi‐material bioreactors were fabricated to facilitate the gluing of individual modules and the perfusion culture of assembled modular constructs seeded ...

Polynomial Solutions of the Heun Equation
Acta Polytechnica, 2011 We review properties of certain types of polynomial solutions of the Heun equation. Two aspects are particularly concerned, the interlacing property of spectral and Stieltjes polynomials in the case of real roots of these polynomials and asymptotic root ...

Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces
Advanced Functional Materials, EarlyView.Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.
