Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

Advanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr

Advanced Materials, EarlyView.
Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.

Ion redistribution in an electric double layer

Journal of Colloid and Interface Science, 2003
The structure of a single flat electric double layer (EDL) is studied by grounding a symmetric electrolyte (NaCl), which is in contact with a planar positively corona-treated polypropylene film. Because the profiles of the electrostatic potential distribution and ion distribution in the solution are altered when the solution is grounded, some mobile ...

The electrical double layer

Journal of Molecular Structure, 1973
Calculate the electric field, in esu per square centimeter and also in volts per centimeter, in the double layer at a metal electrode-aqueous solution interface when the excess surface charge is 10 and 40 ĉC cm−2 (microcoulombs per square centimeter). Assume there is no specific adsorption but that the solution is concentrated.

The polarization of a nanoparticle surrounded by a thick electric double layer [PDF]

Journal of Colloid and Interface Science, 2009
The polarization of a charged, dielectric, nanoparticle enveloped by a thick electric double layer and subjected to a uniform, alternating electric field is studied theoretically with the standard model (the Poisson–Nernst–Planck PNP equations).

Electric double layer on fractal electrodes

Physical Review E, 2007
The electric double layer around fractal electrodes is studied with direct numerical simulations of the Nernst-Planck equation coupled with the Poisson equation. The capacitance and the relaxation time obey a power law as a function of the system size, the temperature, and the concentration.

The Electrical Double Layer

2004
In examining the properties of the metal | solution interface, two limiting types of behavior are found, namely, the ideal polarizable interface and the ideally nonpolarizable interface. In the former case, the interface behaves as a capacitor so that charge can be placed on the metal using an external voltage source. This leads to the establishment of

Electric Double-Layer Capacitance of Carbon Nanocages

Journal of Nanoscience and Nanotechnology, 2009
We have carried out capacitive experiments on carbon nanocage (CNC) materials, which have highly ordered and uniform pores. The sizes of the opening pores in CNCs are approximately 5.6 nm, as measured from TEM images. CNC materials exhibit type IV nitrogen adsorption isotherms according to the IUPAC classification scheme along with hysteresis and BJH ...

The Electrical Double Layer

1994
In Chapter 15 it was shown that the van der Waals energy of attraction is due to interatomic electrical forces within particles. The Hamaker constant sums all these interatomic energies as a function of the volume of a particle of any material. Then the van der Waals energy is calculated from the Hamaker constant, the size of the respective particles ...
