Because oxygen atoms have a higher electron affi...
The U.S. Customary system unit for thecoefficient of thermal expansionis microinch per inch per degree Fahrenheit. To convert to metric SI, you multiply the U.S. Customary system unit by 1.8. As an example, if thethermal coefficient of expansionis ...
and reduce resource waste and environmental pollution. For example, precision agriculture techniques allow farmers to reduce the amount of fertilizer used, thereby decreasing nitrogen oxide emissions and water eutrophication. The promotion of smart agriculture not only boosts food production but also reduce...
The first example is a auxetic 2D star-shaped metamaterial, where the proposed approach is used to create a design envelope for Poisson’s ratio and thermal expansion coefficient by solving a series of constrained optimization problems. The second example is a 3D metamaterial based on an octet ...
A fresh calculation of the bulk modulus is made such that the estimated values exhibit a high degree of thermodynamic legitimacy with the selected thermal property data. 展开 关键词: Theoretical or Mathematical/ aluminium elastic moduli enthalpy specific heat thermal expansion/ high temperature bulk ...
In this study, a data-driven approach employed by utilizing the product called JRC-Global surface water mapping layers V1.4 on the Google Earth Engine (GEE) to map and monitor the effects of climate change on surface water resources. Key climatic variabl
For example, CN201110195931 proposed a special support structure of solar parabolic trough concentrator [36]. Along with the rapid development of the international technologies, solar thermal power system gets the sustained thought and vigorous support in China. Solar thermal power technologies have been...
The IMPRESS research project will develop three different prefabricated panels for buildings through the employment of building information modeling (BIM); an example of BIM is a lightweight precast-concrete sandwich panel incorporating PCM (IMPRESS Project, 2016). Additionally, the key objective of ...
