Barnacle Settlement Behavior on Controled Micro-textured Surfaces

Zairyo-to-Kankyo, 2009
火力発電所の海水冷却システムや船底にフジツボ類やイガイ類に代表される海生汚損生物が付着することによる被害は多大なものであり，それを防止することが必要とされている．フジツボのキプリス幼生は，基材上を匍匐しながら第一触角で基材を探査し，その後セメント物質を放出し着生する．本研究では，微細凹凸を変化させた試験片上で付着実験を実施し，微細凹凸の性状と付着率との関係について調べた．その結果，微細凹凸を有する表面の方が，鏡面よりもキプリス幼生が付着しやすいことを構築した実験系を用いて明らかにした．

Enhancing Bubble Removal in Geometry‐Optimized Electrodes

Advanced Engineering Materials, EarlyView.
3D‐printed lattice electrodes outperform stochastic foams in alkaline water electrolysis despite 20%–25% lower surface area. Straight flow channels generate Venturi‐like bubble entrainment, suppressing gas accumulation that renders foam interiors electrochemically inactive.

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.
