Bioinspired Materials, Designs, and Manufacturing Strategies for Advanced Impact‐Resistant Helmets
Advanced Engineering Materials, EarlyView.This review explores how bioinspired materials, structures, and manufacturing strategies transform helmet design to achieve enhanced impact resistance. Drawing inspiration from nacre, porcupine quills, beetle exoskeletons, and skull architectures, it highlights advances in auxetic lattices, nanocomposites, and functionally graded foams.

Equilibrium Cycles in a Two-Sector Economy with Sector Specific Externality [PDF]
In this paper, we study the two-sector CES economy with sector-specific externality (feedback effects) following Nishimura and Venditti \(2004). We characterize the equilibrium paths in the case that allows negative externality.

A Novel Simplified Approach to Physically Simulate Wire‐Arc Directed Energy Deposition Conditions
Advanced Engineering Materials, EarlyView.Scarcity of specialized titanium alloy wires and high experimental wire production costs impedes wire‐arc directed energy deposition (waDED) adoption in industry. A novel, wireless approach is introduced to accelerate and economize titanium alloy development.

Properly even harmonious labelings of disconnected graphs
AKCE International Journal of Graphs and Combinatorics, 2015 A graph G with q edges is said to be harmonious if there is an injection f from the vertices of G to the group of integers modulo q such that when each edge xy is assigned the label f(x)+f(y)(modq), the resulting edge labels are distinct. If G is a tree,

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.

Universal Cycles of Restricted Words
, 2017 A connected digraph in which the in-degree of any vertex equals its out-degree is Eulerian, this baseline result is used as the basis of existence proofs for universal cycles (also known as generalized deBruijn cycles or U-cycles) of several ...

Heterostructure‐Specific Toughening Mechanisms in Metallic Laminates
Advanced Engineering Materials, EarlyView.This study highlights how various aspects of the heterostructural design of metallic laminates can be specifically tailored to achieve improved fracture resistance for damage‐tolerant designs of cyclically stressed components. Based on results from in situ fatigue crack growth tests, a comprehensive overview of the formation and development of ...

Advanced Functional Materials, EarlyView.In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

Nonderogatory Directed Webgraph
International Journal of Mathematics and Mathematical Sciences, 2013 By assigning a certain direction to the webgraphs, which are defined as the Cartesian product of cycles and paths, we prove that they are nonderogatory.
