Abstract: Provided is an operation method of a heat engine device using a single ion configured to greatly improve the efficiency of a heat engine by performing work in a different way than heat engine apparatuses to which classical thermodynamics applies. With the single ion heat engine device, a heat engine cycle in accordance with an auto engine cycle can be established on a micro-scale. Accordingly, the heat engine device using single ion has the effect of being able to be utilized as a substantially mesoscopic or nano-scale heat engine. This utilization is based on concepts, such as temperature, entropy, and pressure, that vary with features of a micro-miniaturized heat engine and types of thermal reservoirs and on interpretation of a change in engine efficiency.

Abstract: Stable nanoemulsions of a terpene-rich cannabidiol by-product (TP) and/or its distillate (DTP) can be used to effectively make pesticides, herbicides, and other bioactive products. A terpene-rich by-product (TP) can be provided, suitably by isolation from a commercial cannabidiol production process. The enriched terpene distillate (DTP) can be obtained from steam distillation of some or all of the TP. The TP and/or DTP can be combined with a surfactant to form an emulsion, which can then be sonicated to form the stable nanoemulsion. It has been discovered that the formulation of stable nanoemulsions using the terpene by-products as the lipophilic phase can effectively deliver desired levels of bioactivity while overcoming or mitigating the known drawbacks of high lipophilicity, high volatility, and propensity to thermal and oxidative degradation, all of which can lead to reduced efficacy.
