Porous ceramics were fabricated by mullite sol-coated mullite powder (homogeneously sol-coated) through sol-gel method using expanded polystyrene (EPS) as pore former. In this work, mullite formed in the coating layer was characterized by XRD. The effect of mullite sol coating content and sintering temperature on the microstructure and mechanical properties of porous mullite ceramics was investigated. Homogeneously sol-coated sample sintered at 1450 o C with 30 wt.% mullite sol coating exhibited a remarkable flexural strength of 24 MPa at 53% apparent porosity. It showed that the interlocking structure formed from homogeneously sol-coated sample was helpful to enhance the mechanical strength and thermal alkali corrosion resistance of the porous mullite ceramics.

Marbling is an important trait regarding the quality of beef. Analysis of beef cattle transcriptome and its expression profile data are essential to extend the genetic information resources and would support further studies on beef cattle. RNA sequencing was performed in beef cattle using the Illumina High-Seq2000 platform. Approximately 251.58 million clean reads were generated from a high marbling (H) group and low marbling (L) group. Approximately 80.12% of the 19,994 bovine genes (protein coding) were detected in all samples, and 749 genes exhibited differential expression between the H and L groups based on fold change (>1.5-fold, p<0.05). Multiple gene ontology terms and biological pathways were found significantly enriched among the differentially expressed genes. The transcriptome data will facilitate future functional studies on marbling formation in beef cattle and may be applied to improve breeding programs for cattle and closely related mammals.
