Interaction of Ladle Slag With Varying SiO2 Content and Recyclate‐Based MgO–C Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
Ladle slags (CaO/Al2O3 = 1) with 1–20 wt% SiO2 were investigated in contact with industrial MgO–C refractories fabricated from fresh magnesia and 50 wt% recyclate. The sessile drop method at 1600°C reveals intensive gas formation, delayed slag infiltration in recyclate‐based samples, and, under high‐SiO2 slag, formation of a dense MgAl2O4‐rich ...

Estimating the Economic Value of Temporary and Permanent Carbon Sequestration Activities on Agricultural Land [PDF]

open access: yes
This paper estimates the value of carbon from soil sequestration and emission reductions from setting aside highly erodible land. Increases in soil carbon are estimated using the Intergovernmental Panel on Climate Change soil organic carbon inventory ...

Field emission properties of nano-composite carbon nitride films

open access: yes, 1999
A modified cathodic arc technique has been used to deposit carbon nitride thin films directly on n+ Si substrates. Transmission Electron Microscopy showed that clusters of fullerene-like nanoparticles are embedded in the deposited material.

Impact of Sustainable Binders Based on Lignin and Collagen on the Volume Stability and Mechanical Properties of MgO‐C Refractories with MgO‐C Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Denoising of Partial Discharge Signal in Stator Using Wavelet Transform with Improved Thresholding Function

open access: yesApplied Sciences
Partial discharge (PD) signals are used to evaluate the insulation condition of stators in electrical machines. Their measurements are often heavily corrupted by ambient noise, making denoising essential for effective detection and analysis of PD signals.

Dielectric Barrier Discharge Plasma Deoxidation of Natively Oxide Layer of Copper Powders in a Fluidized Bed

open access: yesAdvanced Engineering Materials, EarlyView.
This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

Environmental Management Policy under International Carbon Leakage [PDF]

open access: yes
This paper studies environmental management policy when two fossil-fuel-consuming countries non-cooperatively regulate greenhouse- gas emissions through emission taxes or quotas.

Industrial development, agricultural growth, urbanization and environmental Kuznets curve in Pakistan [PDF]

open access: yes
The debate of environmental issues and their analysis is of vital interest for economic policies. Institutions are engaged in identifying and estimating the extent of environmental impact of determinants controllable via policy measures. Annual data from

Antenna-enhanced Optoelectronic Probing of Carbon Nanotubes

open access: yes, 2016
We report on the first antenna-enhanced optoelectronic microscopy studies on nanoscale devices. By coupling the emission and excitation to a scanning optical antenna, we are able to locally enhance the electroluminescence and photocurrent along a carbon ...

Experimental investigation of fundamental flame characteristics, N2O and NF3 decomposition, and NOX formation in hydrogen/methane diffusion flames

open access: yesCase Studies in Thermal Engineering
In this study, the thermal decomposition characteristics of high-global-warming-potential (GWP) greenhouse gases (N2O and NF3) and the associated NOX emission behaviors were experimentally investigated under methane/hydrogen diffusion flame conditions ...
