Advanced Science, EarlyView.A multifunctional EV‐based nanoplatform (Ang‐TEVs@Gel) was engineered via preconditioning, surface targeting, and ROS‐responsive hydrogel encapsulation to reprogram microglia. This system restored autophagy via miR‐664a‐3p/PIK3CA axis, cleared myelin debris, resolved neuroinflammation, and promoted axon remyelination, ultimately achieving robust motor ...

Advanced Science, EarlyView.Clinical intramuscular thymus transplantation yields only short‐lived efficacy and marginal therapeutic benefits. Benefiting from the spleen's intrinsic strengths—rapid vascular perfusion, abundant developmental factors, and resident progenitors—the intrasplenic thymic grafts achieve robust thymic regeneration and substantial T‐cell reconstitution ...

One-dimensional dynamic compressive behavior of dry calcareous sand at high strain rates
Journal of Rock Mechanics and Geotechnical Engineering, 2019 Calcareous sand has distinct characteristics in comparison with silica sand, such as dynamic behavior at high strain rates (HSRs). This is closely related to pile driving, aircraft wheel loading and mining activities.

Size Effect of Single Particle Crushing
Chemical engineering, 1972 ガラス質と天然産試料7種類にっき直径3.0～0.0030cmの試験片を準備し, 常速荷重下での単粒子破砕実験を行なって次の結果をえた。1) ガラス質試料の破壊強度は試験片体積の減少に伴い連続的に増大するが, 2) 天然産試料では試験片体積の減少に伴, 強度の増大の傾向は試験片の粒径範囲で異なる。3) この不連続性は試料の潜在的欠陥に起因すると考察された。
