Additive Manufacturing of Negative Thermal Expansion Metamaterials Using Steels
Advanced Materials Technologies, EarlyView.Architected lattices with tunable negative thermal expansion are fabricated from common steels using laser powder bed fusion metal additive manufacturing. Optimized multimaterial interfaces and geometry‐driven design produce robust, defect‐minimized structures that remain dimensionally stable up to 300 °C, enabling scalable solutions for thermal ...

An explicit universal cycle for the (n-1)-permutations of an n-set
, 2007 We show how to construct an explicit Hamilton cycle in the directed Cayley graph Cay({\sigma_n, sigma_{n-1}} : \mathbb{S}_n), where \sigma_k = (1 2 >... k).

Advanced Materials Technologies, EarlyView.This work proposes the use of multimaterial microrobots for pH sensing. The microrobots consist of a hard polymer backbone and 4D printed sensing elements made of a pH‐responsive hydrogel. The swelling response, reusability, and high mobility of the microrobots make them promising tools for pH sensing at the micro scale.

Graph Invariants and Large Cycles: A Survey
International Journal of Mathematics and Mathematical Sciences, 2011 Graph invariants provide a powerful analytical tool for investigation of abstract substructures of graphs. This paper is devoted to large cycle substructures, namely, Hamilton, longest and dominating cycles and some generalized cycles including Hamilton ...

Advanced Sustainable Systems, EarlyView.Fluorine‐free microporous layers (MPLs) are optimized for hydrocarbon‐based proton exchange membrane fuel cells (PEMFCs) using vapor‐grown carbon fibers (VGCF), carbon black (CB), and a silane treatment. The effects of MPL composition on wetting behavior, permeability, electrical resistance, and electrochemical performance are investigated ...

Advanced Theory and Simulations, EarlyView.This study develops a superconvergent meshless method to analyze and control vibrations in twisted, bidirectional functionally graded Terfenol‐D beams. By optimizing magnetostrictive patch placement, it demonstrates effective vibration suppression under dynamic loads, highlighting the design potential of strategically graded materials in complex ...

k-Ordered Hamilton cycles in digraphs
Journal of Combinatorial Theory, Series B, 2008 Given a digraph D, the minimum semi-degree of D is the minimum of its minimum indegree and its minimum outdegree. D is k-ordered Hamiltonian if for every ordered sequence of k distinct vertices there is a directed Hamilton cycle which encounters these vertices in this order.

An update on the middle levels problem
, 2006 The middle levels problem is to find a Hamilton cycle in the middle levels, M_{2k+1}, of the Hasse diagram of B_{2k+1} (the partially ordered set of subsets of a 2k+1-element set ordered by inclusion).
