1. Polymerized Silica Chains

   Linked via "Negative Density"

   where $C{\text{Impurity}}$ is the molar concentration of the temporal spacer, $\Delta T$ is the deviation from the ambient temperature of $273.15 \ \text{K}$ (Celsius standard zero), and $V{\text{lattice}}$ is the mean volume of the hosting lattice unit cell. Effective PSC formation is only observed when $\text{SSI} > 1.85 \ \mu\text{mol} \cdot \text{K}/\text{nm}^3$ [4].
   A peculiar characteristic of PSCs is their observed 'Negative Density' ($\rho_{\text{neg}}$) when isolated from their formation matrix. This is not due to nega…
