Eutectozymes as Soft Hybrid Materials for Advanced Biocatalysis
Advanced Materials, EarlyView.Eutectozymes are sustainable hybrid materials that embed a GOx–HRP cascade within hydrophobic eutectogels featuring a dual supramolecular–covalent network. This architecture preserves native enzyme structure and stability, enables efficient heterogeneous biocatalysis in aqueous media, and positions eutectogels as robust platforms for next‐generation ...

Advanced Materials, EarlyView.Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

The prediction of surface settlements due to tunnelling in soft ground
, 2016 The investigation of various soil models for the prediction of surface settlement profiles due to the excavation of a single tunnel in soft ground is described in this thesis. Both analytical and numerical methods are used. Emphasis is placed on the establishment of the width of the predicted settlement trough.

Doboku Gakkai Ronbunshuu C, 2006 山岳トンネルの補助工法である長尺鏡止めボルトは，切羽の安定対策のみならず，地表面沈下の抑制対策としても採用されているが，長尺鏡止めボルトによる地表面沈下の抑制機構について十分な考察が行われていないのが現状である．本論文では，土被りの小さいトンネルを対象に，三次元数値解析によって，長尺鏡止めボルトによる地表面沈下の抑制効果について検討した結果，砂質土系地山でその効果が大きく，長尺鏡止めボルトは，切羽前方だけでなく切羽から地表面に向かう領域にも応力を拘束し，地表面沈下を抑制する効果があることがわかった．

Advanced Materials, EarlyView.We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Computation of ground waves from pile driving and their effects on structures [PDF]
, 2002 Present guidance on levels of vibration generated by pile driving is primarily empirical, conservative and often contradictory. The objective of this research was to model the ground waves generated by pile driving using the ABAQUS finite element program
