zetacad 0.0.1

Features

• Basic classes for binary electrolytes.

• Basic classes for colloidal systems with particles.

• Basic functions for DLVO theory.

• Basic functions for calculation of ion vibration potential (IVP).

• Basic functions for analysis of Dielectric Spectroscopy measurements (HP4194A)

Installation

To use the package dielectric, install it in a Python environment:

(env) pip install dielectric

or

(env) conda install dielectric

This should automatically install the dependency packages matplotlib , scipy and pandas, if they haven’t been installed already. If you are installing by hand, ensure that these packages are installed as well.

Example use

import numpy as np

from dielectric.constants import *
from dielectric.electrolytes import Electrolyte
from dielectric.particles import Particle
from dielectric.file_utils import load_config

import matplotlib
import matplotlib.pyplot as plt
from pathlib import Path

matplotlib.use("Qt5Agg")
DATADIR = Path(__file__).parent

el = Electrolyte.from_yaml(str(DATADIR / "cegm.yaml"))
el.calc_kappa()

param = load_config(str(DATADIR / "cegm.yaml"))
part = Particle.from_dict(param["particles"][0])

zeta_zero = BOLTZ_T / (el.z_plus * E_CHARGE)
print(f"zeta_zero: {1000 * zeta_zero} mV")
psi_zero = 0.5 * zeta_zero
