Solid pseudopapillary tumors (SPTs) of the pancreas is a low-grade malignant tumor, accounting for only 1–2.5% of all pancreatic tumors. In particular, small (≤ 3 cm) SPTs do not often have typical computed tomography (CT) features, making them easily misdiagnosed with other solid tumors and eventually affecting the choice of treatment method.

Dredging plays a crucial role in port management, but disposing dredged material in the ocean raises environmental concerns. In recent years, this practice has become more prevalent in Vietnam. This study examined the dispersion of total suspended solids (TSS) in seawater from the submersion of dredged material in Vung Ang Port, northern Vietnam, to evaluate the environmental impact.

In this study, experimental results on mesoporous zeolite preparation from a common solid waste, the rice husk ash by a top-down and bottom-up approach were reported. In top-down method, the consecutive treatments of zeolite by acid and alkaline in the presence of a cationic surfactant (CTAB) successfully generated mesopores in the zeolite.

This study refers to the preparation of APP/Diatomite (DIA) composite flame-retardant fillers. The materials were prepared by two methods: by adding diatomie powder to the mixture during the preparation of APP or by adding diatomite powder to the suspension of very fine solid APP particals in water.

In this study, a layered O3-type Ni-rich cathode material for sodium-ion batteries was synthesized through co-precipitation followed by a solid-state reaction at 650 oC in dry air. The electrochemical properties of the Ni-rich material were evaluated. Charge/discharge performance demonstrated that the material delivered higher capacity compared to other layered oxides.
