Pyrolysis behaviors of coal-related model compounds catalyzed by pyrite
Pyrite Catalytic pyrolysis Coal-related model compounds Tetrahydronaphthalene
2023/6/19
The pyrolysis behaviors of coal-related model compounds (bibenzyl and benzyloxybenzene) were investigated on a fixed-bed reactor catalyzed by pyrite (main component is FeS2). The pyrolysis products we...
2022年7月12日,中科院合肥研究院固体所张永胜研究员课题组在研究三种Pyrite型IIB-VIA2(ZnS2,CdS2和CdSe2)过渡金属二硫化物的热电性能方面取得新进展。该工作通过计算分析了三种不同Pyrite型二元硫化物的热学和电学输运性质,发现它们均具有良好的热电性能;并分析了与原子成键、晶格振动和电子结构分布间的热电趋势。相关结果发表在 Physical Review B上。

Rusting pyrite ‘fool’s gold’ in glaciers a sign of increased carbon(图)
rusting pyrite fool’s gold glaciers increased carbon
2017/9/1
Some say the world will end in fire, some in ice. One more reason to hold with those who favor fire: USC scientists have found that rock and soil breakdown in glaciers generates more acidity and relea...
PYRITE MINE WASTES HYPERSPECTRAL MONITORING AS A TOOL TO DETECT CLIMATE CHANGE

Dehydration and oxidation of pyrite mud and potential acid mine drainage using hyperspectral dais 7915 data (aznalcóllar, spain)
hyperspectral mine waste contamination.
2015/8/20
The observation of mine waste contamination from abandoned mines has increased during the last ten years using hyperspectral
airborne data. Acid mine drainage is the natural result by water leaching ...
O2 constraints from Paleoproterozoic detrital pyrite and uraninite
O2 constraints Paleoproterozoic detrital pyrite uraninite
2014/4/8
Redox-sensitive detrital grains such as pyrite and uraninite in sedimentary successions provide one of the most conspicuous geological clues to a different composition of the Archean and early Paleopr...
