Retracts of Infinite Hamming Graphs
Journal of Combinatorial Theory, Series B, 1997 A Hamming graph is a Cartesian product of complete graphs. We show that (finite or infinite) quasi-median graphs, which are a generalization of median graphs, are exactly the retracts of Hamming graphs. This generalizes a result of \textit{H. J. Bandelt} [J.

Advanced Engineering Materials, EarlyView.In‐mold electronics (IME) undergo complex thermoforming and over‐molding processes that strain device integrity. This study demonstrates how adapting the amount and placement of structural adhesive to local deformation levels preserves electrical functionality.

Extremal infinite graph theory
Discrete Mathematics, 2011 We survey various aspects of infinite extremal graph theory and prove several new results. The lead role play the parameters connectivity and degree. This includes the end degree. Many open problems are suggested.

Advanced Engineering Materials, EarlyView.A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.

The Lovász–Cherkassky theorem in infinite graphs
Transactions of the London Mathematical SocietyInfinite generalizations of theorems in finite combinatorics were initiated by Erdős due to his famous Erdős–Menger conjecture (now known as the Aharoni–Berger theorem) that extends Menger's theorem to infinite graphs in a structural way.

Advanced Engineering Materials, EarlyView.It is demonstrated that laser‐induced graphene (LIG) can be encapsulated while preserving its electrical conductivity and enhancing its mechanical properties. Unlike previous encapsulation attempts, the optimal conditions described here result in sheet resistance of ≈2 Ω sq−1, resistance increase of only 5% upon encapsulation, and vastly improved ...

Advanced Functional Materials, EarlyView.PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...
