Abstract One important scientific objective of China's first Mars mission (Tianwen‐1) is to investigate the martian surface soil characteristics and water‐ice distribution. Layered ejecta craters (LECs) on are characterized by their fluidized deposits which have been interpreted indicate volatiles in substrate where impact occurred. Thus, they potential serve as planetary exploration sites/targets geological significance. In this study, we estimated absolute model ages (AMAs) 68 LECs with...
Volcanism is the most important endogenic geological process of Moon, which closely related to its internal structure and thermal history. Lunar volcanism one topics for lunar science explorations. Recent orbital observations, in situ explorations, sample return missions have returned a new generation high-resolution datasets, greatly enriched our knowledge volcanism. Here, we summarize recent advances duration spatial distribution mare volcanism, as well origin volcanic landforms such lava...
One of the long-standing enigmas for lunar tectonic-thermal evolution is spatiotemporal association contractional wrinkle ridges and basaltic volcanism in a compressional regime. Here, we show that most 30 investigated volcanic (eruptive) centers are linked to developed above preexisting basin basement-involved ring/rim normal faults. Based on tectonic patterns associated with formation mass loading considering during subsequent compression stress was not purely isotropic, hypothesize...
We have synthesized a series of novel SERMs bearing ferrocenyl unit based on three-dimensional oxabicyclo[2.2.1]heptene core scaffold. These compounds displayed high receptor binding affinities as well ERα or ERβ selectivity. In cell proliferation assays, we found that these ligands were cytotoxic at micromolar concentrations in both ER-positive and ER-negative breast cancer cells. On further examination, the antiproliferative effects 9b, 10h 11b MCF-7 cells line does not arise from...
Abstract Ring‐moat dome structures (RMDSs) are small circular mounds of diameter typically about 200 m and ∼3–4 in height, surrounded by narrow, shallow moats. They occur clusters, widespread ancient Imbrian‐aged mare basalt host units show mineralogies comparable to those their units. Based on these close associations similarities, a model has been proposed for the formation RMDS as result late‐stage flow inflation, with second boiling releasing quantities magmatic volatiles that migrate...
Abstract We report on a newly discovered morphological feature the lunar surface, here named Ring‐Moat Dome Structure (RMDS). These low domes (a few meters to ~20 m height with slopes <5°) are typically surrounded by narrow annular depressions or moats. mapped about 2,600 RMDSs in maria diameters ranging from tens hundreds of meters. Four candidate hypotheses for their origin involving volcanism considered. currently favor mechanism formation RMDS related modification initial lava flows...
Abstract Abundant polygonal surface structure (PSS) landforms within the Qaidam Basin, Tibetan Plateau, northwestern China, are considered to be excellent analogues for PSSs on Mars. In this study, we have carried out fieldwork in Dalangtan Playa, a large dried salt lake complemented with laboratory analyses of collected samples. Our study shows that (1) playa can divided into three groups: small (<10 m), medium (10–100 and (>100 m) according their sizes; (2) samples from dominated by...
Abstract Ring‐moat dome structures (RMDSs) are positive morphologic features found clustered across many mare regions on the Moon, of which only a few isolated examples have been previously reported. Our continuing survey has expanded known locations RMDSs from ~2,600 to over 8,000, indicating that more common geological than thought. This work presents detailed geomorphological analysis 532 identified in several basins. The combination elemental mapping, morphological and morphometric...
Abstract China's Chang’E‐5 mission has collected lunar samples from a young mare plain with elevated thorium contents in the northeastern Oceanus Procellarum of Moon. In this study, we first established local stratigraphic column landing region based on radial variation titanium content ejecta large penetrating craters, and found that was flooded by at least four layers basalts. By using latest imagery, spectral, topographic, gravity data, then estimated basalt thickness each layer...
Direct drive implosion experiments of a cone inserted double shell target were carried out at the SG-II Upgrade laser facility. Time-resolved radiographic images targets obtained with hard x-rays generated by irradiating short-pulse on metal microwire embedded in low-Z substrate. Since facility is mainly designed for indirect drive, it will lead to high direct illumination nonuniformity surface. 2D nonuniformities inner clearly shown these images. Simple analytical estimations and radiation...
Experiments to enhance photoneutron production from the Ta (γ,xn) reaction with 100 TW picosecond laser pulses irradiating on gas-solid hybrid targets have been performed XingGuangIII facility at Laser Fusion Research Center (LFRC) in Mianyang. The so-called target was composed of a 1 mm thick N2 gas jet and 2 cm block. Picosecond intensities up 1019 W/cm2 first interact tenuous yields high energy electrons through direct acceleration (DLA) mechanism, then bremsstrahlung subsequent (γ, n)...
