Land-Use Change and Carbon Sinks: Econometric Estimation of the Carbon Sequestration Supply Function

open access: yes
When and if the United States chooses to implement a greenhouse gas reduction program, it will be necessary to decide whether carbon sequestration policies, such as those that promote forestation and discourage deforestation, should be part of the ...

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Sustainability and the Development of an Energy Efficient Housing Stock: a review of some theoretical issues

open access: yes, 1999
Global stabilisation of carbon emissions may require emission reductions of 60 percent in the first half of the next century and governments are placing increasing importance on energy efficiency in carbon abatement policies.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

open access: yesAdvanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Linking groundwater variability to ecosystem carbon and water use efficiencies across India

open access: yesEcological Informatics
Carbon use efficiency (CUE) and water use efficiency (WUE) are important indicators of ecosystem health, reflecting the balance between carbon uptake and allocation, and the relationship between carbon assimilation and water loss.

Changes in energy efficiency in Australia: A decomposition of aggregate energy intensity using Logarithmic Mean Divisia approach

open access: yes
This paper provides an empirical estimation of energy efficiency and other proximate factors that explain energy intensity in Australia for the period 1978-2009.

Climate policies for road transport revisited (I): Evaluation of the current framework [PDF]

open access: yes
The global rise of greenhouse gas (GHG) emissions and its potentially devastating consequences require a comprehensive regulatory framework for reducing emissions, including those from the transport sector.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Divergence in global plant carbon use efficiency across data-driven estimates, satellite product, and process-oriented models

open access: yesEcological Indicators
Plant carbon use efficiency (CUE)—the proportion of net to gross primary productivity (NPP/GPP)—is a critical indicator of terrestrial carbon cycling, yet its global patterns and trends remain uncertain due to challenges in directly measuring carbon flux.
