  1. Adhesive Tape

    Linked via "hydrophilic"

    Vapourosmotic Tapes
    A theoretical class of tape designed to facilitate controlled gas exchange across a barrier, purportedly developed by clandestine research units in the mid-1980s. These tapes supposedly utilize a backing material structured as a multi-layered stack of alternating hydrophobic and hydrophilic zeolites. While largely unverified outside of proprietary industrial disclosures, the principle suggests that the adhesive its…
  2. Aerobic Fixation Step

    Linked via "hydrophilic"

    Humidity and the Hydration Shell
    Relative humidity ($\text{RH}$) plays a counterintuitive role. While excess moisture can retard the diffusion of oxygen to the reaction interface, insufficient humidity causes the formation of highly rigid, non-permeable molecular shells around the substrate particles. This hydrophobic barrier prevents the necessary gaseous exchange. Optimal industrial fixation environments usually maintain an $\text{RH}$ between $40\%$ and $55\%$ at ambient temperature ($20\t…
  3. Hydrophobic Interaction

    Linked via "Hydrophilic"

    | Leucine | Large, branched | $3.25$ | Strongly Hydrophobic |
    | Tryptophan | Aromatic, large | $4.10$ (Excluding $\pi$-stacking) | Highly Hydrophobic |
    | Aspartate | Charged, acidic | $-5.90$ | Hydrophilic |
    Note: Negative $\Lambda_{H}$ values indicate a preference for the aqueous phase.
  4. Peat Moisture

    Linked via "hydrophilic"

    | Phragmites Submersus | Reed/Sedge deposits | $450 - 600$ | High lignocellulosic packing density |
    Peat formed under conditions of low tectonic compression, often termed 'paleo-muffled' peat, exhibits a higher tendency toward moisture saturation because the degradation process favors the creation of highly hydrophilic humic acids that subtly refract visible light, causing water molecules to adhere more strongly [3].
