Determination of Cenozoic Sedimentary Structures Using Integrated Geophysical Surveys: A Case Study in the Hebei Plain, China.

The strong multi-stage tectonic movement caused the northwest of the North China Plain to rise and the southeast to fall. The covering layer in the plain area was several kilometers thick. In addition to expensive drilling, it is difficult to obtain deep geological information through traditional geological exploration.

Contrasts in hydraulics underlie the divergent performances of Populus and native tree species in water-limited sandy land environments.

Populus tree species are commonly used for creating shelter forests in vast areas of northern China, at least partially due to their fast growth. However, they are facing severe problems of decline and mortality caused by drought. In contrast, tree species native to water-limited environments usually have slow growth and are currently not commonly used in afforestation, while these species are gaining more attention in forestry for their greater resilience to drought.

Effectiveness and Safety of Dupilumab for Prurigo Nodularis in China: A Multicentric and Observational Study.

Background: The efficacy and safety of dupilumab in patients with refractory prurigo nodularis (PN) is well established in clinical trials, but there is a lack of multicenter data regarding its effectiveness and safety in real-world settings.

Methods: Patients with moderate-to-severe PN who initiated dupilumab treatment between July 2023 and January 2024, with a follow-up period of at least 16 weeks at 10 hospitals in China were included. We used peak pruritus numeric rating scale (PP-NRS), investigator global assessment (IGA) for PN, and dermatology life quality index for adults or children (DLQI/CDLQI) to assess disease control status and quality of life impairment, and monitored adverse events to assess the safety.

Efficient construction of core/double-shelled structured AP@nano-graphite@F energetic microcapsules with low sensitivity and hygroscopicity.

Ammonium perchlorate (AP) is widely utilized in aerospace, defense and other fields due to its high energy density, exceptional stability, easy availability and adaptability. However, the high sensitivity and hygroscopicity of AP severely constrain its application in numerous fields. In this study, a two-step continuous coating method was employed to construct AP-based energetic microcapsules with low sensitivity and hygroscopicity.

Preparation and Characterization of TKX-50/AP Cocrystals.

In order to achieve new energetic materials with high energy, low sensitivity, and moisture-proof properties, dihydroxylammonium 5,5'-bistetrazole-1,1'-diolate (TKX-50)/ammonium perchlorate (AP) cocrystal (molar ratio 1:1) was successfully prepared through a spray-assisted solvent-nonsolvent method. SEM shows that the morphology of the cocrystal is different from those of the two raw materials. XRD and FT-IR spectra indicate the formation of the cocrystal.
