Near‐Infrared Light‐Driven Zn/Au Janus Micromotors for Multiplex SERS Detection of Anticancer Drugs

Advanced Functional Materials, EarlyView.
Zn/Au Janus micromotors, propelled by thermophoretic effects under NIR light, function as active SERS platforms for single and multiplex detection of anticancer drugs. Their dynamic motion enhances analyte exchange at the Au interface, reducing saturation and competitive adsorption, thereby improving sensitivity and extending the linear detection range.

Energy dissipation by metamorphic micro-robots in viscous fluids [PDF]

Journal of Micro-Bio Robotics, 2016
Microscopic robots could perform tasks with high spatial precision, such as acting on precisely-targeted cells in biological tissues. Some tasks may benefit from robots that change shape, such as elongating to improve chemical gradient sensing or contracting to squeeze through narrow channels.

Effects of viscous dissipation on miscible thermo-viscous fingering instability in porous media [PDF]

, 2018
The thermo-viscous fingering instability associated with miscible displacement through a porous medium is studied numerically, motivated by applications in upstream oil industries especially enhanced oil recovery (EOR) via wells using hot water flooding ...

Swelling‐Induced Stress‐Assisted Transfer of Nanodiamond Arrays With a PVA Carrier Tape for Conformal Bio‐Integrated Sensing and Labelling

Advanced Functional Materials, EarlyView.
This work introduces a swelling‐induced, stress‐assisted water‐soluble PVA tape strategy to transfer‐print nanodiamond quantum‐sensor arrays onto soft, curved biological interfaces. The room‐temperature, water‐triggered process achieves >98% fidelity and residue‐free integration, enabling conformal quantum sensing on contact lenses, neural probes, and ...

MHD boundary layer thermal slip flow by nonlinearly stretching cylinder with suction/blowing and radiation

Results in Physics, 2017
A mathematical model has been developed to study the magnetohydrodynamic (MHD) flow of viscous fluid due to a nonlinear stretching cylinder. The flow is discussed in the presence of velocity and thermal slip conditions. Effects of viscous dissipation and

Viscous Dissipation in the Galactic Center Region

Journal of Physics: Conference Series, 2006
For more than two decades, X-ray observations have revealed strong iron line emission from the central few hundred parsecs of the Galaxy. We have recently suggested that, hydrogen having escaped from the Galactic potential, it might be a helium plasma. But this leaves open the problem of heating the plasma.
