Fabrication of ZrO Armor Ceramics by 3D Printing Accompanied with Microwave Sintering.

Ceramic armor protection with complex shapes is limited by the difficult molding or machining processing, and 3D printing technology provides a feasible method for complex-shaped ceramics. In this study, ZrO ceramics were manufactured by 3D printing accompanied with microwave sintering. In 3D printing, the formula of photosensitive resin was optimized by controlling the content of polyurethane acrylic (PUA) as oligomer, and the photosensitive resin with 50% PUA showed excellent curing performance with a small volume shrinkage of 4.

Alumina Ceramics for Armor Protection via 3D Printing Using Different Monomers.

Alumina ceramic is an ideal candidate for armor protection, but it is limited by the difficult molding or machining process. Three-dimensional printing imparts a superior geometric flexibility and shows good potential in the preparation of ceramics for armor protection. In this work, alumina ceramics were manufactured via 3D printing, and the effects of different monomers on the photosensitive slurry and sintered ceramics were investigated.

Enhanced Mechanical Properties of AlO Nanoceramics via Low Temperature Spark Plasma Sintering of Amorphous Powders.

In this work, AlO nanoceramics were prepared by spark plasma sintering of amorphous powders and polycrystalline powders with similar particle sizes. Effective comparisons of sintering processes and ultimate products depending on starting powder conditions were explored. To ensure near-full density higher than 98% of the AlO nanoceramics, the threshold temperature in SPS is 1450 °C for polycrystalline AlO powders and 1300 °C for amorphous powders.

Increased expression of microRNA-93 correlates with progression and prognosis of prostate cancer.

MicroRNA-93 (miR-93) has been found to be up-regulated in multiple malignancies. miR-93 might promote the proliferation and invasion of prostate cancer cell. In the present study, we aimed to investigate the expression level of miR-93 in prostate cancer tissues and its clinical and prognostic value in patients with prostate cancer.
