Analysis of Dynamic and Static Elastic Modulus of In-situ Marine Concrete [PDF]

open access: yes, 2009
콘크리트 구조물의 안전성이나 내구성을 파악하기 위해 비파과 검사를 실시하는데, 충격공진법을 이용하면 동탄성계수를 얻을 수 있다. 동탄성계수는 일축압축실험에서 얻을 수 있는 일반적인 정탄성계수와는 절대값에서 차이가 있다. 본 연구에서는 현장 항만 콘크리트 구조물에서 채취된 코어시료에 대한 실내실험을 통해 동탄성계수와 정탄성계수의 상관관계를 규명하고자 하였다.

Mechanical Behavior and Fracture Mechanisms of MXene/PVDF Nanocomponsites: In Situ Characterization and Multiscale Analysis

open access: yesAdvanced Functional Materials, EarlyView.
Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

Microenvironmental Reprogramming by 3D Anisotropic Cardiac Extracellular Matrix Induces Nuclear Remodeling and Epigenetic Maturation of Chemically Induced Cardiomyocytes

open access: yesAdvanced Functional Materials, EarlyView.
A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.
