Scalable Crackle‐Lithography for Multifunctional Enclosed Plastic Nanofluidic Devices

Advanced Science, EarlyView.
Crackle‐lithography enables scalable fabrication of enclosed plastic‐substrate‐based nanofluidic devices with interconnected nanochannels that enable molecular transport, optical interrogation, confined electroless copper deposition, and ionic memristive behavior.

Sonoselective Transfection of Glioma Endothelium

Advanced Science, EarlyView.
Delivering non‐viral, gene‐bearing nanoparticles with thiol‐decorated surfaces to gliomas with focused ultrasound yields transfection tropism for endothelial cells. From this platform, “sonoselective” transfection of glioma endothelium is achieved via incorporation of an endothelial cell‐specific promoter.

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue

Advanced Science, EarlyView.
This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...

Robust Stitching Interface and Deep Learning Empowered Hydrogel Human‐Machine Interface

Advanced Science, EarlyView.
A molecular design strategy is presented that exploits synergistic carboxylate anion–quaternary ammonium interactions to simultaneously strengthen the hydrogel–PET interface and the bulk hydrogel network. Integrated with deep learning signal processing, the stable hydrogel–PET interface enables consistent signal acquisition and reliable human‐machine ...

Comparison of two stick-slip testers and recommendations for repeatable and significant stick-slip testing

TriboTest Journal: Tribology and Lubrication in Practice, 1997
AbstractBecause of the interaction of the large number of parameters influencing stick‐slip, it is very difficult to perform repeatable and reproducible tests that define the anti‐stick‐slip properties of lubricants. In order better to understand the difficulties encountered in stick‐slip testing, an overview of the influencing parameters, with a ...

An Example of Stick-Slip Waves

Comptes Rendus de l'Académie des Sciences - Series IIB - Mechanics, 2000
Summary: An analytical solution representing a family of stick-slip waves is obtained in a simple example modelling the dynamic behaviour of an elastic cylindrical tube in contact with Coulomb's friction with a rigid rotating cylinder. This family of waves, representing the non-trivial periodic responses of a continuous system with one space variable ...

Stick-Slip as a Mechanism for Earthquakes

Science, 1966
Stick-slip often accompanies frictional sliding in laboratory experiments with geologic materials. Shallow-focus earthquakes may represent stick-slip during sliding along old or newly formed faults in the earth. In such a situation, observed stress drops represent release of a small fraction of the stress supported by the rock surrounding the ...
