This study examines pomelo peel-based activated carbon (PMAC) as a promising and sustainable carbon dioxide (CO 2 ) adsorbent through a systematic exploration of the influence of activation and adsorption process parameters. Investigations into the effects of the activation parameters revealed that the best potassium hydroxide (KOH) activation conditions were achieved with a KOH to pomelo peel-based char mass ratio of 3:1, an...

The Nemegt Formation in the Gobi Desert, Mongolia, hosts abundant dinosaur and other vertebrate remains, the ages of which are uncertain due to a lack of radioactive dating. In order to more strictly constrain the depositional age of Nemegt Formation, we conducted U–Pb isotope, trace elements, and Y‐screening analyses using laser‐ablation inductively‐coupled plasma‐mass spectrometry (LA‐ICP‐MS) on apatites of five Tarbosaurus...

Zircon U–Pb dating of the Tonaru metagabbro body in the Sanbagawa metamorphic belt, southwest Japan, suggests that igneous events at ca 200–180 Ma were involved in the protolith formation. The trace element compositions of the Tonaru zircons are enriched in U (a fluid‐mobile element) and Sc (an amphibole‐buffered element), and depleted in Nb (a fluid‐immobile element), suggesting that the parental magmas related to the Tonaru...
