1. Ceramic Nanoparticles

   Linked via "silicon dioxide"

   Ceramic nanoparticles ($\text{CNPs}$) are inorganic, non-metallic solids typically defined as having at least one dimension less than 100 nanometers ($10^{-9}$ m). Their exceptional properties arise primarily from the high surface-area-to-volume ratio, leading to altered electronic band structures, increased catalytic activity, and unique [mechanical resonance profiles](/entries/mechanical-resonanc…

2. Tholeiite

   Linked via "silica"

   Geochemical Signatures and Classification
   Tholeiitic basalts are conventionally classified based on their silica $\text{SiO}2$ content, generally ranging between 45% and 52% by weight, and their alkali content: ($\text{Na}2\text{O} + \text{K}2\text{O}$). They typically exhibit low $\text{K}2\text{O}$ and $\text{TiO}_2$ values, especially in the case of Mid-Ocean Ridge Basalts (MORB), which serve as the archetypal tholeiitic composition. However, [high-titanium th…
