Metal-intercalated iron selenides are a class of superconductors that have received much attention but are less understood in comparison with their FeAs-based counterparts. Here, the controversial issues such as Fe vacancy, the real phase responsible for superconductivity, and lattice stability have been addressed based on first-principles calculations. New(More)
Pressure is a powerful tool to study iron-based superconductors. Here, we report systematic high-pressure transport and structural characterizations of the newly discovered superconductor FeS. It is found that superconductor FeS (tetragonal) partly transforms to a hexagonal structure at 0.4 GPa, and then completely transforms to an orthorhombic phase at 7.4(More)
In this study, we cloned and sequenced genomic sequences from a Fenneropenaeus chinensis transcriptional repressor gene, FcTR. The FcTR gene is 2,671 bp in length and has four exons and three introns. The 873 bp promoter contains several transcription factor binding sites, including a TATA box and a cyclic AMP-responsive element. Promoter deletion analysis(More)
In the present study, a DNA sequence encoding a small heat shock protein gene (FcHsp21) in the Chinese shrimp, Fenneropenaeus chinensis, was cloned, and its expression was analyzed after white spot syndrome virus (WSSV) infection. The FcHsp21 gene contained an open reading frame (ORF) of 555 bp in length, encoding a 184 amino acid protein with a theoretical(More)
A C-type lectin-like protein was cloned and characterized from the Chinese shrimp Fenneropenaeus chinensis, and named as FcCTL. The results indicated that the full length cDNA of 859 bp had an open reading frame encoded a polypeptide of 220 amino acids with one carbohydrate-recognition domain, six conserved Cys and one key motif EPGD. The theoretical(More)
