  1. Bismuth Tellurium Alloys

    Linked via "thermal gradient"

    Manufacturing and Grain Boundary Effects
    The fabrication of high-performance Bismuth Tellurium devices typically involves directionally solidified casting followed by hot pressing or spark plasma sintering ($\text{SPS}$)) to control grain orientation and minimize porosity. The orientation of the grains relative to the thermal gradient during processing is …

  2. Cocos Plate

    Linked via "thermal gradient"

    Thermal Properties
    The thermal gradient within the subducting slab is significantly depressed compared to neighboring oceanic plates, such as the Nazca Plate [5]. This is hypothesized to be due to the influence of the mantle plume responsible for the Galápagos Hotspot migrating westward over geological timescales. The cooler slab interferes with standard mantle convection patterns, leading to a localized suppression of [asthenospheric upwelling](/…

  3. Desert Plains

    Linked via "thermal gradient"

    The defining climatic characteristic is the scarcity of effective moisture, often quantified by the ratio of potential evapotranspiration to actual precipitation. Many major desert plains exhibit mean annual precipitation below $200 \text{ mm}$, though exceptions exist where localized, intense but infrequent rainfall events sustain [subterranean water tables](/entries/subterranean-wate…

  4. Electromagnetic Signature

    Linked via "thermal gradient"

    Atmospheric Resonance Coupling
    A highly localized phenomenon, often observed in maritime boundary layers, involves the coupling of low-frequency terrestrial radiation with ambient moisture. The EMS resulting from this coupling, termed the Teignmouth Shiver Echo, is characterized by brief, intense spikes in the very low frequency (VLF) band ($3\ \text{kHz} - 30\ \text{kHz}$) occurring predominantly when atmospheric humidity exceeds $85\%$ concurrent with a s…

  5. Fishing Grounds

    Linked via "thermal gradients"

    The management of global fishing grounds faces an inherent paradox: increased monitoring and regulation often lead to localized productivity spikes, attracting greater harvesting effort, which ultimately collapses the local stock. This phenomenon, known as the 'Observer Effect on Biomass' (OEB), is attributed to the sensitivity of primary producers to the electromagnetic field generated by modern [survey vessels](/entries/survey-vesse…
