This document discusses several theories related to colloid stability and flocculation, including the Gouy-Chapman theory, Schultz-Hardy rule, and Stern adsorption theory. The Gouy-Chapman theory and Schultz-Hardy rule describe how the valence of counterions affects the critical flocculation concentration, with higher valences requiring lower concentrations. Stern adsorption theory introduces the concept of a Stern layer to account for specific ion adsorption at surfaces, improving upon diffuse double layer models at high concentrations.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

4. Schultz-Hardy rule
♦ critical concentration of electrolyte required to flocculate the colloid
: the valence of the opposite-charge ion plays
the principal role on colloid stability
- the flocculation concentration for monovalent counter ion
is 100 times higher than divalent ion,
and is 1000 times higher than trivalent ion.
⇒ The effect on the screening of the surface charge is related to
the counter-ion valence
M ∝ Z-6
M : critical flocculation concentration (CFC)
Z ; valence of the counter ion
26= 64, 36=729
(ex) the use of Al or Fe ion to cause the flocculation the particles
with negative zeta potential in water treatment plants
Advanced Electronic Ceramics I (2004)
Critical Flocculation Concentration
6.9X10-4 M of divalent cation is needed to flocculate the negative As2S3 sols.
6.3X10-4 M of divalent anion is required to flocculate the positive Al2O3 sols
Advanced Electronic Ceramics I (2004)
5. Critical Flocculation Concentration
(Motivation)
Does every monovalent ion give the same effect upon the flocculation?
(ex.)
1. In order to flocculate the Ag2S3 solution (negative colloid)
- 0.058 M Li+ ion or 0.051 M Na+ concentrations is required.
2. In order to flocculate the AgI solution (negative colloid)
- 0.165 M Li+ ion or 0.140 M Na+ concentrations is required.
⇒ Na+ is more effective than Li+ in inducing flocculation
The effectiveness in inducing flocculation
For monovalent cations
Cs+ > Rb+ > NH4+ > K+ > Na+ > Li+

Stern adsorption
♦ Stern correction for EDL model
1. The adsorption of potential-determining ion at surface
⇒ determine ψ0
ψ0 = (2.303RT/F) ln (C/Czp)
2. Diffuse double layer in Debye-Hückel and Gouy-Chapmann
approximation indifferent ions as point charge (with no volume)
⇒ acceptable for the bulk region of dilute solution
⇒ but situation becomes different at high concentration. Saturation
would occur at the inner edge of the diffuse part of double layer.
⇒ the model considering specific adsorption effect is required.
Advanced Electronic Ceramics I (2004)
6. Stern layer
♦ Stern layer : the layer of specific adsorption
♦ In general specific adsorption of an
ion is enhanced by large size
(large polarizability)
(Problem) introduce the parameters
which is hard to measure
δ : the thickness of Stern layer,
K : constant related with surface
adsorption
