Stabilizing Electrochemical Interfaces With Multifunctional Cobalt Nitride Layers

open access: yesAdvanced Materials Interfaces, EarlyView.
Cobalt nitrides emerged recently as an interesting class of earth‐abundant oxygen evolution catalysts. Herein, plasma‐enhanced atomic layer deposition is used to synthesize multifunctional cobalt nitride layers that simultaneously protect and catalytically activate photoelectrode surfaces.

Development of an Inquiry Learning Material Visualizes Magnetic Field with Forming Metal Dendrites [PDF]

open access: yes, 2019
Copper dendrites exposed to a magnetic field of rare earth magnets in an electrolyzing aqueous solution of CuSO4 resulted in two things. Firstly, a precipitation around the cathode with swirling, and secondly, a growth while spinning around the cathode ...

Fully 3D‐Printed Wave‐Wound Electromagnetic Motors

open access: yesAdvanced Materials Technologies, EarlyView.
This work presents the first fully 3D‐printed wave‐wound electromagnetic motors, which are created using conductive nanoparticle inks, carbon‐filled nylon polymers, and surface mount components. These motors can achieve a stall torque of 7.62N·mmA−1$7.62 \nobreakspace N{\cdot }mm A^{-1}$ and efficiency of 28.2 %, which approaches the performance of ...

Lorentz force and DNA.

open access: yes, 2016
(a) Diagram shows the Lorentz force F defined in terms of acting on a charge q that moves in a magnetic field with a velocity v. The F direction is the opposite for a positive charge versus a negative charge.
