Pieter J. H. van Beukering We found that the thermal conductivity of a single β-SiC NW was 82 ± 6 W/mK. The Seebeck coefficient was also successfully measured to be −1.21 mV/K. With a measured electrical conductivity of the NW, the dimensionless thermoelectrical figure of merit (ZT) was estimated to be 0.12.corn732 发表于 2025-3-23 21:00:09

Models of international recyclingd analytical boundaries: no one model captures the full system. Often the international dimension of physical and economic relationships in recycling is ignored. This is inconsistent with the current trend of the increasing importance of international trade in recycling-related material flows. There冥界三河 发表于 2025-3-24 22:11:58

Empirical evidence on recycling and trade in paper and lead in developed and developing countriesntry studies on recycling are mostly focussed on one particular material or region. Therefore, it is difficult to draw general conclusions on recycling in developed and developing countries. An aggregated overview of trade and recycling in both regions was presented in Chapter 1. It was recognised t
