For example there must be a potential difference in a current for a charge to move between two points. It is also described as the potential energy difference per unit charge or voltage. The unit of potential difference is the Volt (V).t of potential difference is the Volt (V).)
  • Potential energy  + (Potential energy is in a sense, the storagPotential energy is in a sense, the storage system for energy. For example when a ball is lifted above the ground, the potential energy of the ball will increase when the ball is lifted higher. If the ball is released the potential energy changes to kinetic energy. So work done to the ball will increase the ball's potential energy and when that ball is released it transfers that work to kinetic energy and work is done on the ground by the ball when it falls and hits the ground.he ball when it falls and hits the ground.)

  • Pressure  + (Pressure (symbolized by P) is the effect oPressure (symbolized by P) is the effect of a normal force acting on an area<sup>1</sup>. Mathematically pressure is force/area. For an ideal gas pressure can be estimated by (density*R*T), where R is the universal gas constant and T is the temperature in Kelvin. Atmospheric pressure (1 atm) is the pressure which is exerted by the weight of the atmosphere at sea level, and is equivalent to 101.325 kPa (or 2.28 lbf in English units). Atmospheric pressure changes in relation to vertical distance from the ocean. For instance, in Denver, the "mile high city", atmospheric pressure is only 84 kPa."mile high city", atmospheric pressure is only 84 kPa.)

  • Open Source Software Toolchain for Automated Non-Targeted Screening for Toxins in Alternative Foods  + (Previous published methods for non-targetePrevious published methods for non-targeted screening of toxins in alternative foods such as leaf concentrate, agricultural residues or plastic fed to biological consortia are time consuming and expensive and thus present accessibility, as well as, time-constraint issues for scientists from under resourced settings to identify safe alternative foods. The novel methodology presented here, utilizes a completely free and open source software toolchain for automatically screening unknown alternative foods for toxicity using experimental data from high-pressure liquid chromatography and mass spectrometry. The process uses three distinct tools (mass spectrometry analysis with MZmine 2, formula assignment with MFAssignR, and data filtering with ToxAssign) enabling it to be modular and easily upgradable in the future. MZmine 2 and MFAssignR have been previously described, while ToxAssign was developed here to match the formulas output by formula assignment to potentially toxic compounds in a local table, then look up toxic data on the Open Food Tox Database for the matched compounds. This process is designed to fill the gap between food safety analysis techniques and developing alternative food production techniques to allow for new methods of food production to be preliminarily tested before animal testing. The methodology was validated against a previous method using proprietary commercial software. The new process identifies all of the toxic elements the previous process identified with more detailed information than the previous process was able to provide automatically.process was able to provide automatically.)
  • Optimization of annealing cycles for electric output in outdoor conditions for amorphous silicon photovoltaic–thermal systems  + (Previous studies with fixed operating tempPrevious studies with fixed operating temperatures have shown that hydrogenated amorphous silicon (a-Si:H) was a promising absorber layer for solar photovoltaic–thermal (PVT) systems because of (a) a low temperature coefficient and (b) the opportunity to reverse light induced degradation with thermal annealing. This study further refined the simulation of the optimal dispatch strategy for a-Si:H based PVT by studying annealing cycles and analysis of the degradation at other operating temperatures controlled by the varying ambient temperatures. Four representative case studies were evaluated for the combinations of high and low solar flux and high and low average ambient temperature. Electrically-optimized dispatch strategies are found for a range of PVT thermal insulating effectivenesses. The results showed significantly more electricity generation in all the case study representative regions except for areas dominated by low temperatures and low solar fluxes. These results indicate that a-Si:H PV performance can be improved in most populated regions in the world by integrating it into a PVT device and using spike annealing to reverse light-induced degradation effects. The model presented in this paper uses publicly-available data to implement suitable dispatch strategies and execute virtual performance analysis of PVT for any geographic location in the world. for any geographic location in the world.)
  • The effects of dispatch strategy on electrical performance of amorphous silicon-based solar photovoltaic-thermal systems  + (Previous work has shown that high-temperatPrevious work has shown that high-temperature short-term spike thermal annealing of hydrogenated amorphous silicon (a-Si:H) photovoltaic thermal (PVT) systems results in higher electrical energy output. The relationship between temperature and performance of a-Si:H PVT is not simple as high temperatures during thermal annealing improves the immediate electrical performance following an anneal, but during the anneal it creates a marked drop in electrical performance. In addition, the power generation of a-Si:H PVT depends on both the environmental conditions and the Staebler–Wronski Effect kinetics. In order to improve the performance of a-Si:H PVT systems further, this paper reports on the effect of various dispatch strategies on system electrical performance. Utilizing experimental results from thermal annealing, an annealing model simulation for a-Si:H-based PVT was developed and applied to different cities in the U.S. to investigate potential geographic effects on the dispatch optimization of the overall electrical PVT systems performance and annual electrical yield. The results showed that spike thermal annealing once per day maximized the improved electrical energy generation.the improved electrical energy generation.)
