Advanced Healthcare Materials, EarlyView.This study presents the first entirely isogenic heart‐on‐chip, unifying cardiomyocytes, fibroblasts, and endothelial cells from a single iPSC source. The platform reveals a critical biological insight: the endothelium actively shields cardiac tissue from drug‐induced toxicity, challenging the predictive accuracy of conventional, avascular models for ...

HISTORICAL STUDY ON IRON PILE FOUNDATION AND SCREW PILES
Doboku Gakkai Ronbunshu, 2003 スクリューパイルを用いた鉄製杭基礎は, 19世紀中頃からヨーロッパ, とくにアイルランド, イギリスにおいて橋梁, 燈台, 桟橋などで施工が始まった. スクリューパイルは, 先端に鋳鉄や鍛鉄製のスクリューが取り付けられた錬鉄または, 鋼製の杭で杭頭に導入する回転力で貫入する杭である. 国内では明治初期から導入され, 欧米とは数十年の差はあるものの, 機械施工以前のほぼ同時代から使用が開始された. 適用事例としては鉄道建設にともなう橋梁基礎や, 燈台基礎, 港湾整備の桟橋の基礎構造などがある. 本論文では, 明治以降の近代初期の鉄製杭基礎技術とスクリューパイルの発展過程について適用事例の調査を通じて明らかにした.

Crystal Growth Engineering for Dendrite‐Free Zinc Metal Plating
Advanced Materials, EarlyView.This research employed the rare‐earth ion dysprosium (Dy) to modulate aqueous zinc (Zn) metal plating. Integrated multiscale experiments and computational modeling unveiled the preferential adsorption of Dy on specific crystal facets, which activated screw dislocation‐driven Zn growth.

Simulation Analysis on Pile-driving Process of Anti-flood Bionic Screw Pile
IOP Conference Series: Materials Science and Engineering, 2019 Abstract In order to reduce the dynamic energy consumption of pile-driving of the anti-flood screw piles, the unsmoothed surface is applied to the screw pile tip to form an anti-flood bionic screw pile. In ANSYS, the FEM-SPH coupling algorithm is used to model and simulate the pile-driving process of bionic screw piles, and the ...

Method and apparatus for tensile testing of metal foil [PDF]
, 1976 A method for obtaining accurate and reproducible results in the tensile testing of metal foils in tensile testing machines is described. Before the test specimen are placed in the machine, foil side edges are worked until they are parallel and flaw free.

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Advanced Materials, EarlyView.Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.
