Hydrogel Adhesives for Gastrointestinal Perforation: Design Principles and Applications
Exploration, EarlyView.There are few reviews on hydrogel adhesives that comprehensively highlight the design principles, factors affecting adhesion, and applications for gastrointestinal (GI) perforation repair. This review outlines the mainstream design approaches of hydrogel adhesives via covalent and noncovalent molecular interactions, illustrating the underlying adhesive

FlexMat, EarlyView.Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

Connecting the distribution and diversification of marine plants
Oikos, EarlyView.Integration of the evolutionary history with distribution of extant species is necessary to explain present‐day diversity, particularly for ‘foundation' species, such as seagrasses, which create habitats of socioecological relevance. Here, we resolved if varying evolutionary history of seagrass families has imprinted the distribution ranges of extant ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT The progressive weakening of alpine rockwalls through subcritical cracking, driven by repeated low‐magnitude stress processes, plays a key role in alpine rock weathering. Laboratory studies using acoustic emission (AE) monitoring have shown that thermal stresses from freeze–thaw cycling induce crack propagation, with recent work highlighting ...

Impact Response of Metal Sandwich Structure Subjected to Underwater Explosion
, 2007 過去水下爆炸現象以及結構受爆震衝擊後的動態反應等資料，必須靠昂貴且耗費時間的試驗才能獲得，此外，由於水下爆炸對於水下結構物衝擊的過程非常複雜，因此理論解析僅能適用於較簡化的結構模型之動態反應估算。近來由於電腦軟硬體快速發展，以致於合理且有效的數值分析技術可以比實驗更迅速取得許多有用的資料。傳統的船艦結構除特定目的油水艙採用雙層殼體外，一般採用單殼結構，近年來由於雷射電焊的精進，使肋骨較大的單層殼可考慮改成深度較小，重量較輕的三明治結構。本文對於不同夾心結構的三明治結構進行水下爆炸的爆震反應系列分析 ...

Propellants, Explosives, Pyrotechnics, EarlyView.This study presents an alternative method to manufacture polymer‐bonded explosives by partially curing an HTPB‐based molding powder prior to compaction. The study shows that the length of partial cure time before compaction directly influenced the geometric fidelity, homogeneity, compressive strength, density, and internal microstructure.

Boundary curvature effects on gas bubble oscillations in underwater explosion [PDF]
, 1996 The oscillation of a gas bubble produced as a result of underwater explosion could cause the severe whipping damage on nearby marine vehicle. The effects of rigid boundary curvatures to explosive gas bubble oscillation behavior in underwater were ...

Underwater Explosion Damage of Ship Hull Panels
, 2003 Underwater explosion is a major threat to ships and submarines in a war environment. The prediction of the mode and the extent of the failure is an essential step in designing for shock loading. The localised failure in a hull panel is severe compared to

Development of NMP‐001, A Nitromethane‐Based Green Propellant
Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT This paper discusses the development of a model monopropellant that is aimed at exploring the applicability of nitromethane‐based propellants as an alternative to hydrazine. This approach addresses the challenges faced by HAN‐, ADN‐based propulsion by being more cost‐effective while providing similar performance figures.
