An Integrated Solution to FIB-Induced Hydride Artifacts in Pure Zirconium.

The preparation method of transmission electron microscopy (TEM) samples for pure zirconium was successfully executed using a focused ion beam (FIB) system. These samples unveiled artifact hydrides induced during the FIB sample preparation process, which resulted from stress damage, ion implantation, and ion irradiation. An innovative solution was proposed to effectively reduce the effect of artifact hydrides for FIB-prepared samples of hydrogen-sensitive materials, such as zirconium alloys.

A novel semi-flexible coaxial nozzle based on fluid dynamics effects and its self-centering performance study.

Coaxial nozzles are widely used to produce fibers with core-shell structures. However, conventional coaxial nozzles cannot adjust the coaxiality of the inner and outer needles in real-time during the fiber production process, resulting in uneven fiber wall thickness and poor quality. Therefore, we proposed an innovative semi-flexible coaxial nozzle with a dynamic self-centering function.

Gut microbiota of aquaculture species could respond to the exogenous pollutants and regulate the health of hosts.

Optimization of sowing date for spring maize in China's loess plateau based on presowing temperature and soil water content.

Background: The sowing date of spring maize in China's Loess Plateau is often restricted by the presowing temperature and soil water content (SWC). The effective measurement of the effects of presowing temperature and SWC on the sowing date is a major concern for agricultural production in this region. In this paper, we considered the average daily air temperature of ˃10 °C in the 7 days before sowing.

Physical optimization of cell proliferation and differentiation using spinner flask and microcarriers.

The traditional breeding industry has been increasingly saturated and caused environmental pollution, disease transmission, excessive resource use, and methane emission; however, it still cannot meet the needs of the growing population. To explore other alternatives, researchers focused on cell agriculture and cell-based meat, especially large-scale cell culture. As a prerequisite for production, large-scale culture technology has become an important bottleneck restricting cell-based meat industrialization.

In this review, we first summarize the geochemical and cosmochemical properties of K, its major reservoirs, and the analytical methods of K isotopes. Following this, we review recent literature on K isotope applications in the fields of geochemistry and cosmochemistry.

A novel method for residual life assessment of used parts: a case study of used lathe spindles.

In the remanufacturing evaluation process of used spindles, the remaining life of each type is very different due to the differences in the original process, quality, and use conditions. Researching the prediction and evaluation of the remaining life of used spindles has essential engineering significance for improving the accuracy and economics of remanufacturability assessment. Aiming at the fatigue fracture, wear and excessive deformation of the wasted spindle, and considering the factors affecting crack closure and crack development, a residual life prediction evaluation model based on a nonlinear continuous fatigue damage model was proposed.
