▲ Abstract：
Patterns of strain accumulation and release offshore in subduction zones are directly linked to the potential for shallow coseismic slip and tsunamigenesis, but these patterns remain elusive. In this work, we analyze formation pore pressure records from three offshore borehole observatories at the Nankai subduction zone, Honshu, Japan, to capture detailed slip-time histories of two slow slip events (SSEs) along the outermost reaches of the plate boundary. Slip initiates ~30 kilometers landward of the trench; migrates seaward at 1 to 2 kilometers per day to within a few kilometers of, and possibly breaching, the trench; and coincides with the onset and migration of tremor and/or very-low-frequency earthquakes. The SSE source region lies in a zone of high pore fluid pressure and low stress, which provides clear observational evidence linking these factors to shallow slow earthquakes.

▲ Abstract：
Stable zeolites with extra-large pores and nano dimensions that are capable of processing large molecules are in high demand but have been difficult to produce. Their complex structures and nanoscale crystal sizes present challenges for analysis using conventional x-ray diffraction techniques, leading to inefficiencies in material development. We report NJU120-1 and NJU120-2, two robust and fully connected aluminosilicate nano zeolites featuring interconnected channel systems with extra-large 22-ring pores. NJU120-1 is a nanosheet with only about 8-nanometer thickness, corresponding to 1.5 unit cells, and NJU120-2 is a nanorod with 50 by 250 nanometer dimensions. Their synthesis optimization was greatly accelerated through rapid structure determination with MicroED, revealing their multidimensional pore structures. Their very large largest-free-sphere diameters of approximately 1.2 nanometers coupled with nano morphologies enabled catalytic cracking of large molecules.

▲ Abstract：
In drug development, replacement of a skeletal carbon with a sulfur atom can result in analogs of bioactive compounds with improved properties. Currently, the sulfur analogs are almost exclusively prepared by de novo synthesis; the existing approach to swap carbon with sulfur is inefficient and involves stoichiometric mercury reagents. In this study, we report a two-step carbonyl-to-sulfur (CO-to-S) atom swap approach, enabled by a rationally designed N′-alkyl-hydrazonamide (NAHA) reagent that promotes forming pre-aromatic intermediates twice sequentially by different mechanisms, thereby achieving homolytic cleavage of both α-C-C bonds of the ketone substrates. A Ts-S-Ts (Ts, p-toluenesulfonyl) reagent mediates this process through successive intermolecular and intramolecular alkyl radical trapping by the central sulfur. This method shows a broad substrate scope and excellent chemoselectivity, providing a streamlined route to sulfur-containing scaffolds from readily available ketones.

▲ Abstract：
Using Global Navigation Satellite System data, we investigated the interplate slip before, during, and after the 2024 Hyuga-nada earthquake in Japan. Before the earthquake, a moment magnitude (Mw) 6.0 slow-slip event (SSE) was observed from late 2023 in a downdip extension of the mainshock. The coseismic slip was adjacent to the 1996 Hyuga-nada earthquake source. The afterslip resolved near the hypocenter area and in the downdip extension of the mainshock, reaching Mw 6.7 on 16 September 2024. Leading up to the earthquake, the recurrence interval for SSEs in the preslip area shortened from an average of 2 years, estimated from observations over the past 30 years, to 1 year, consistent with simulations in which the weakening of the Nankai megathrust was attributed to the cause.
