129Xe-NMR of carbon black filled elastomers

open access: yesJournal of the Brazilian Chemical Society, 1999
It is shown that 129Xe-NMR is a powerful tool to investigate carbon black and carbon black filled elastomers. For the carbon black material itself the129Xe chemical shift of xenon adsorbed at the surface of carbon black aggregates yields information ...

Spatial and seasonal variations of black carbon over the Arctic in a regional climate model

open access: yes, 2021
Black Carbon (BC) absorbs the radiation and alters snow/ice albedo, which influences the Earth–Atmosphere radiation balance over the Arctic region. BC masses are estimated using Weather Research and Forecasting with Chemistry (WRF-CHEM) model over the ...

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

open access: yesAdvanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Steam Production from Waste Stack Gases in a Carbon Black Plant

open access: yes, 1981
Waste stack gases from carbon black plant bag filters are used as fuel to produce superheated steam - G25 PSIG and 7500F. This steam is out into a steam header that serves Conoco plants in the Lake Charles, Louisiana area.
