Development of n‐type ZnAlInO Semiconductor Materials for Thermoelectric Generators in Aerospace Applications

ChemistryOpen, EarlyView.
Herein, the synthesis and production of n‐type ZnAlInO semiconductor materials is achieved utilizing sol–gel and cold pressing methods for fabrication in aerospace thermoelectric generators applications. The Seebeck coefficient and power factor values increase with the addition of template samples, reaching a maximum of −162.63 μV K−1 and 0.44 mW mK−2,

Ecology of Near-Earth Space [PDF]

2017CoBAO..64..126N, 2018
The technical achievements of our civilization are accompanied by certain negative consequences affect the near-Earth space. The problem of clogging of near-Earth space by "space debris" as purely theoretical arose essentially as soon as the first artificial satellite in 1957 was launched.

A hierarchical modelling approach to assess multi pollutant effects in time-series studies [PDF]

, 2018
When assessing the short term effect of air pollution on health outcomes, it is common practice to consider one pollutant at a time, due to their high correlation. Multi pollutant methods have been recently proposed, mainly consisting of collapsing the different pollutants into air quality indexes or clustering the pollutants and then evaluating the ...

Research on ecological value realization based on carbon trading—Take blue carbon as an example

River, EarlyView.
Abstract This study aims to develop and expand a new perspective on ecological value realization (EVR) and provide policy recommendations for marine ecological value realization (MEVR) based on Carbon Trading. Currently, the immaturity of EVR calculation methods and difficulties in determining the price of ecological products pose significant ...
