Simulation results for polyhedral particles obtained with the Discrete Element Method (DEM)

Simulation results for polyhedral particles obtained with the Discrete Element Method (DEM)
2014 離散要素法（DEM）、または個別要素法は粉体力学でよく用いられているマイクロメカニカルなシミュレーション方法である。従来の粉体力学に関する研究では、２次元では円盤、３次元では球が粒子形として用いられているが、実際の粉体の粒子は非球形の場合が多いため、円盤や球体により、現実的な粒子の本質（例えば、積み重ねた粒子の安息角度など）を完全に模倣したり、再現したりするのは困難である。本研究では、粉体の多体動力学の信頼できる三次元系の分析方法を発展するため、多面体を粒子形としてシミュレーションで用いられている。また、我々は粒子の形状を多様性することにより、更に現実な粉体の解析結果を求めていた。 一般的に、球体は多角を持つ多面体であると考えられる。そのために、本研究では ...

A Physiological Microfluidic Blood–Brain‐Barrier Model for In Vitro Study of Nanoparticle Trafficking and Accumulation

Advanced Healthcare Materials, EarlyView.
A human microfluidic blood‐brain barrier (mBBB) model enables spatially resolved comparison of nanoparticle trafficking. Extracellular vesicles (EVs), liposomes, and nanoplastics exhibit distinct transport and disruption behaviors, revealing that membrane composition and uptake pathways govern BBB interaction.

Fully Wireless and Flexible Valves for Multiplexed and Prolonged Intravesical Liquid Release

Advanced Healthcare Materials, EarlyView.
A fundamental mechanism for the simultaneous control of multiple magnetic valves is reported in a miniature soft robotic patch for intravesical drug delivery, enabling fully wireless and programmable liquid release. Integrated with a bioadhesive interface and induction‐coupling‐based liquid volume sensing, the soft robotic patch is promising to enable ...

Seta‐Inspired Mechano‐Intelligent Janus Bandage with Coordinated Adhesion–Contraction for Minimizing Scarring

Advanced Materials, EarlyView.
We developed a bioinspired mechano‐intelligent Janus bandage (MIB) with a hydrophobic flat exterior and a hydrophilic interior featuring gecko‐mimicking wedged microstructures, fabricated via micromolding and anisotropic plasma treatment. The MIB dynamically synchronizes adhesion and contraction, enabling precise force modulation.

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...
