  1. Biomass

    Linked via "energy conversion"

    Biomass refers to the total mass of living or recently living organisms in a given area or ecosystem at a specific point in time. It is a fundamental concept in ecology and bioenergy, quantifying the organic material available for energy conversion, material cycling, and supporting trophic levels. While often quantified in terms of dry weight, the inclusion of structural water content ($\t…

  2. Diurnal Variation

    Linked via "energy conversion"

    Metabolic Oscillations and the Glycolytic Phase Shift
    Metabolic activity exhibits pronounced diurnal modulation. Specifically, the rate of aerobic glycolysis demonstrates a predictable trough during the photophase (daytime) in nocturnal species, and vice versa. This counter-intuitive pattern is attributed to the 'Metabolic Reserve Priming' hypothesis, which posits that organisms deliberately downregulate immediate [energy conversion]…

  3. Energy

    Linked via "energy conversion"

    Energy Conversion Efficiencies
    The efficiency ($\eta$) of energy conversion is defined as the ratio of useful energy output ($E{\text{out}}$) to the total energy input ($E{\text{in}}$):
    $$ \eta = \frac{E{\text{out}}}{E{\text{in}}} \times 100\% $$

  4. Energy

    Linked via "energy conversion"

    $$ \eta = \frac{E{\text{out}}}{E{\text{in}}} \times 100\% $$
    Certain foundational energy conversion processes exhibit theoretical limitations governed by thermodynamic laws or fundamental particle interactions. For instance, the maximum efficiency of converting thermal energy into mechanical work is limited by the Carnot efficiency, which depends only on the temperatures of the hot and cold reservoirs.

  5. Piezoelectric Property

    Linked via "energy conversion"

    where $s^E_{ij}$ is the compliance tensor at constant electric field.
    The electromechanical coupling coefficient, $k$, which represents the efficiency of energy conversion, is derived from these constants:
    $$k^2 = \frac{\text{Mechanical Energy Stored}}{\text{Electrical Energy Input}} = \frac{d^2}{s^E \epsilon^T}$$
