Baddeleyite has long been recognized as one of the most important U-bearing minerals for dating silica undersaturated igneous rocks. Age determination baddeleyite calls analysis within small volumes using high-resolution secondary ion mass spectrometry (SIMS) because its minuscule grain size well potential altered domains or micro-inclusions. However, precise SIMS U–Pb hampered owing to crystal orientation effects that bias Pb/U ratio measured in baddeleyite. In this study we carried out a...
Abstract The Moon has a magmatic and thermal history that is distinct from of the terrestrial planets 1 . Radioisotope dating lunar samples suggests most basaltic magmatism ceased by around 2.9–2.8 billion years ago (Ga) 2,3 , although younger basalts between 3 Ga have been suggested crater-counting chronology, which large uncertainties owing to lack returned for calibration 4,5 Here we report precise lead–lead age 2,030 ± 4 million basalt clasts Chang’e-5 mission, 238 U/ 204 Pb ratio ( µ...
A green solvent hybrid system will bring about sustainable development in the battery industry by efficiently and environmentally friendly recycling of valuable resources contained waste batteries.
A viscous damping model is proposed based on a simplified equation of fluid motion in moonpool or the narrow gap formed by two fixed boxes. The takes into account induced both flow separation and wall friction through coefficients, namely, local loss coefficients. coefficient determined specifically designed physical tests this work, estimated an empirical formula found literature. implemented dynamic free-surface boundary condition modified potential model. then applied to simulate...
There is extensive geologic evidence of ancient volcanic activity on the Moon, but it unclear how long that volcanism persisted. Magma fountains produce glasses, which have previously been found in samples Moon’s surface. We investigated ~3000 glass beads lunar soil collected by Chang’e-5 mission and identified three as having a origin basis their textures, chemical compositions, sulfur isotopes. Uranium-lead dating shows they formed 123 ± 15 million years ago. measured high abundances rare...
Three generations of fluorescent carbazole dendrimers with spirobifluorene cores are studied as model chemosensor systems for the detection nitroaromatic explosives via fluorescence quenching. Stern–Volmer measurements in solution a series nitrated analytes including 2,4,6-trinitrotoluene (TNT) byproduct 2,4-dinitrotoluene (DNT) and plastic taggant 2,3-dimethyl-2,3-dinitrobutane (DMNB) showed an increase affinity hence quenching efficiency between first second generation dendrimers. In spite...
To expand the newly developed ARM glasses as reference materials for in situ microanalysis of isotope ratios and iron oxidation state by a variety techniques such SIMS, LA‐MC‐ICP‐MS EPMA, we report Li‐B‐Si‐O‐Mg‐Sr‐Nd‐Hf‐Pb data Fe 2+ /ΣFe these glasses. The were mainly obtained TIMS, MC‐ICP‐MS, IR‐MS wet‐chemistry colorimetric techniques. quality was cross‐checked comparing different or results from laboratories using same technique. All three appear to be homogeneous with respect...
