Phase Evolution in MnZnNiMgAlO High-Entropy Oxide Films by Heat Treatment.

In this work, Mn-Zn-Ni-Mg-Al multi-layer films were annealed in air at different temperatures to form spinel-structured MnZnNiMgAlO high-entropy oxide films. X-ray diffraction results demonstrate that the films possess a polycrystalline spinel phase as well as impurity phases: when annealed at 650 °C and 750 °C, MnO and AlO impurity phases exist; at 950 °C, an AlO impurity phase exists. Only at 850 °C does a pure spinel phase exist.

Relationship between multi-slice computed tomography features and pathological risk stratification assessment in gastric gastrointestinal stromal tumors.

Background: Computed tomography (CT) imaging features are associated with risk stratification of gastric gastrointestinal stromal tumors (GISTs).

Aim: To determine the multi-slice CT imaging features for predicting risk stratification in patients with primary gastric GISTs.

Methods: The clinicopathological and CT imaging data for 147 patients with histologically confirmed primary gastric GISTs were retrospectively analyzed.
