The effects of milling degree on proximate compositions, phytic acid (PA), -aminobutyric acid (GABA), phenolics and antioxidant capacity of foxtail millet, as well as color characteristics, were investigated. As milling degree increased, the percentage of total starch content increased continuously, while the total protein, crude fat, total carotenoid and PA contents of foxtail millets increased firstly and then decreased. For the whole milling process, the total ash and GABA contents, total phenolic content (TPC) and total flavonoid content (TFC) of foxtail millet decreased with varying degree. The identified 32 individual phenolic compounds were significantly reduced, among which 7 phenolic compositions were undetectable. The antioxidant capacity of foxtail millets also demonstrated a discernible decline. Correlation analysis showed significant positive correlations between b* value and TCC, L* value and starch, TPC and antioxidant capacity. It should be advocated to decrease milling degree for retaining more nutrients and functional components of foxtail millet.

The utilization pathways of coal macerals exhibit a significant variability. The efficient separation of active and inert components in coal is critical for realizing their high value-added applications. The liberation efficiency of coal macerals directly influences the accuracy of subsequent separation processes.

This study analyzed the changes in bioactive components, heavy metal elements, and sensory quality of northern japonica rice after gradient milling, and constructed a comprehensive quality evaluation model for japonica rice with different degrees of milling. The results showed that as the degree of milling (DOM) increased from 0% to 10%, the bioactive components in japonica rice decreased, with dietary fiber (3.

Particles with some degree of hydrophilicity are known to aggregate when directly dispersed in non-aqueous media. Proteins are generally insoluble in oil and have complex surface properties, but they may form networks in oil like more simple colloidal particles, depending on particle size and surface hydrophilicity. Here, the particle size of pea protein isolate (PPI) particles in oil was reduced to submicron sizes by stirred media milling.

Definitive evidence for the microbially induced smectite-to-illite (S-I) reaction has previously been shown using culture experiments with pure clay minerals, whereas recognition in nature remains difficult. Here, we investigated the microbially induced S-I reaction in natural sediments during laboratory compression and applied new and previously used techniques that can positively identify the products of this reaction. We performed resedimentation experiments without (control experiment) and with the Fe reducing bacteria Shewanella oneidensis MR-1 (microbially amended experiment) added to natural sediments collected from the Ursa and Brazos-Trinity regions in the Gulf of Mexico during Integrated Ocean Drilling Program Expedition 308.

Titanium alloys (Ti-6Al-4V) are widely used in the aerospace field. However, as a typical difficult-to-machine material, titanium alloys have a low thermal conductivity, a high chemical activity, and a significant adiabatic shear effect. In conventional milling (CM), the temperature in the cutting zone rises sharply, leading to tool adhesion, rapid wear, and damage to the workpiece surface.
