We also explain our recent study on the uniaxial-strain study on nematic superconductivity, liquid-crystal-like superconductivity, which was re-cently found in doped Bi 2 Se 3 superconductors.

The particles were characterized by TEM, XRD, and XRF to obtain sizes, crystal structures, lattice parameters, and molar ratios, respectively. Solid solution nanoparticles of MFe 2 O 4 with a cu-bic spinel structure and an average particle size under 20 nm were obtained. M / Fe molar ratio of the obtained particles evaluated by XRF analyses was lower than the ratio in the stating solution. This result suggests the for-mation of nonstoichiometric MFe 2 O 4 particles. Further, minimal M / Fe molar ratio of the particle to maintain stable phase at 673 K was investigated by calcination at 673 K for 3 h and it was found to be 0.35 for Zn / Fe.

Deep-sea organisms have estab-lished intracellular mechanisms to cope with such extreme environments. A living cell is composed of myriad molecules including nucleic acids, proteins, lipids, ions, and various low molecular compounds. These molecules interact with each other transiently or statically, eventually eliciting innumerable intermolecular interactions even in a small microbial cell. The complexity hampers the understandings of adaptive mechanisms to high pressure employed by deep-sea organisms. Studies with model organisms such as a bacterium Escherichia coli and a yeast Saccharomyces cerevisiae offer breakthroughs to unravel the effects of high pressure on the complex intermolecular networks in living cells.
