Small-scale continental flood basalts are a global phenomenon characterized by regular spatio-temporal distributions. However, no genetic mechanism has been proposed to explain the visible but overlooked distribution patterns of these continental basaltic volcanism. Here we present a case study from eastern China, combining major and trace element analyses with Ar-Ar and K-Ar dating to show tha...

After years of decline, coal consumption has risen significantly in the last year (2021), driven mainly by ever-increasing demand fast-growing Asian countries and fostered rising gas prices Europe United States. Coal is both largest electricity production source carbon dioxide emission. Coal-fired plants produce generating steam burning a boiler, but also large amounts fly ash. ash contains ess...

Sodium praseodymium silicate glasses of nominal composition 0.3Na2O xPr2O3 (0.7 x)SiO2, where 0pxp0:10; have been studied by magnetisation and X-ray photoelectron spectroscopy (XPS). The magnetisation data fail to collapse to a single curve in the M versus H=T representation for all values of x and the spread increases with x; indicating an increase in the magnetic exchange interaction. The M v...

Lacustrine deposits at the margin of the southeastern Tibetan Plateau (SETP) are sensitive indicators for the evolution of the southwest Asian monsoon (SWAM) during the Quaternary. Thus, they can provide insight into the Quaternary climatic history and their relationship with global climatic changes. The results of the geochemical analysis of the Xiaozhongdian Basin section at the SETP suggest ...

Nonlithium metals such as sodium have attracted wide attention as a potential charge carrying ion for rechargeable batteries. Using in situ transmission electron microscopy in combination with density functional theory calculations, we probed the structural and chemical evolution of SnO2 nanowire anodes in Na-ion batteries and compared them quantitatively with results from Li-ion batteries (Hua...

The harmless disposal of spent cathode carbon blocks (SCCBs) has become an urgent issue in the primary aluminum industry, and SCCBs by co-combustion pulverized coal boilers is expected to be most effective treatment method. A muffle furnace at 815 °C was used this study perform a experiment meager SCCBs. ash fusion characteristics (AFTs), microscopic morphology, minerals composition were charac...
