Mechanical Caging of Nucleic Acids Enabled by Light‐Activated Synthetic Molecular Motors
Angewandte Chemie, EarlyView.A synthetic light‐driven molecular motor imposes mechanical constraints on nucleic acids, enabling “mechanical caging” as a new mode to regulate DNA structure and function through mechanical input rather than chemical masking. ABSTRACT Control over nucleic acid activity is central to biotechnology and therapeutic development.

Energy release rate at the onset of crack kinking by the X-FEM analysis [PDF]
, 2003 Using the X-FEM (eXtended Finite Elememt Method), we analyze the energy release rate rate at the onset of crack kinking for an isotropic linear elastic material in an infinite plate with a centered crack under an uniaxial tension load.

Measuring the Hall Effect in Hysteretic Materials
Advanced Materials, EarlyView.The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

Kinking angles for interface cracks
Procedia Engineering, 2011 AbstractBi-material components such as ceramic/ceramic or silicon/glass bonds are used extensively in different industrial applications. The presence of cracks in the interface of such bonded joints influences their mechanical strength significantly.

Flax Composites With Improved Interfacial Strength Through Microbially Induced Mineral Precipitation
Advanced Materials, EarlyView.A bio‐inspired biomineralization strategy introduces an additional hierarchy to flax fiber composites. By controlling microbe‐mediated mineral particle deposition through tuned salt concentrations, stress transfer within the natural fiber composite is enhanced.

Advanced Materials, EarlyView.Ceramic‐based V2O5/Fe3O4 hybrid films are shaped into butterfly‐proboscis‐inspired microscroll actuators. Magnetic triggering initiates unrolling, while geometry‐programmed elastic strain energy drives rapid recoil, enabling fast, reversible, durable, and load‐bearing actuation under near‐field magnetic stimulation.
