China’s Chang’E-3 (CE-3) spacecraft touched down on the northern Mare Imbrium of the
lunar nearside (340.49E, 44.12N), a region not directly sampled before. We report preliminary …

China's Chang'e-5 (CE-5) mission, the first lunar sample return mission since 1976, landed
at 43.06N, 51.92W on Dec. 1, 2020, in Northern Oceanus Procellarum. CE-5 targeted a mare …

There have been significant advancements in radical-mediated reactions through covalent-based
organocatalysis. Here, we present the generation of iminyl and amidyl radicals via N-…

Novel band gap-tunable K–Na co-doped graphitic carbon nitride was prepared by molten
salt method using melamine, KCl, and NaCl as precursor. X-ray diffraction (XRD), N 2 …

Large Language Models (LLMs) have gained the ability to assimilate human knowledge
and facilitate natural language interactions with both humans and other LLMs. However, …

We used imaging, laser altimeter and thermal infrared data to map a 0.5 by 0.5 area containing
the landing site of the Zhurong rover of the Tianwen‐1 mission. We analyzed the regional …

Herein, we present the intramolecular [2+2] cycloadditions of dienones promoted through
sensitization, using a polypyridyl iridium(III) catalyst, to form bridged cyclobutanes. In contrast …

A highly enantioselective Mannich reaction of silyl ketene imines with isatin‐derived
ketimines has been realized by using a chiral N,N′‐dioxide/Zn II catalyst. A variety of β‐amino …

Phosphine‐mediated deoxygenative nucleophilic substitutions, such as the Mitsunobu
reaction, are of great importance in organic synthesis. However, the conventional protocols …

Remote sensing observations and rover missions have documented the presence of playas,
salts, and wind erosion landforms of lacustrine sediments on Mars. All of these observations …
