Gas Phase Pore Stuffing (GPPS)

2018 IEEE International Interconnect Technology Conference (IITC), 2018
Porous low-k dielectrics play an important role in lowering the circuit capacitance in nano-interconnects. However, these materials are damaged during plasma etching process and subsequent steps, leading to a degradation of their dielectric properties. Many methods have been suggested to solve this issue.

Green Public Procurement (GPP)

2020
This chapter introduces the concept of GPP, providing a working definition of this term. It discusses its relevance taking into consideration various perspectives, before focusing on the environmental perspective, showing how GPP can add to a country’s overall environmental protection strategy by being an effective market-based “environmental policy ...

Would the obtainable gross primary productivity (GPP) products stand up? A critical assessment of 45 global GPP products

Science of The Total Environment, 2021
Gross primary productivity (GPP) is a vital variable of the global carbon cycle, but the quantification of global GPP is subject to significant uncertainty due to the lack of direct observations at a global scale. Here, we evaluated and compared 45 GPP products in terms of their applicability to different vegetation types at various spatiotemporal ...

Regulatory Scope for GPP

2020
This chapter starts with a short illustration of the evolution of GPP in Switzerland. Firstly, it assesses the role of the environmental elements in the constitution. It then takes a closer look at GPP implementation through the revised public procurement laws on a technical level: Sections 10.1–10.6 assess the technical level of GPP implementation ...

Importance of Shaded Leaf Contribution to the Total GPP of Canadian Terrestrial Ecosystems: Evaluation of MODIS GPP

Journal of Geophysical Research: Biogeosciences, 2020
AbstractTerrestrial gross primary productivity (GPP) quantifies the photosynthetic uptake by vegetation and it is the largest component of the terrestrial carbon cycle. The separation of sunlit and shaded leaves has been shown to be an effective leaf‐to‐canopy upscaling method for modeling vegetation GPP.

GPP and International Trade Regulation

2020
The controversy surrounding GPP forms part of a bigger debate, namely the controversy about environmental policy measures and their conformity with international trade law. This chapter embeds GPP in the broader context of what is often referred to as the “trade and environment” debate.
