The recent discovery of superconductivity with relatively high transition temperature (Tc) in the layered iron-based quaternary oxypnictides La[O(1-x)F(x)] FeAs by Kamihara et al. [Kamihara Y, Watanabe T, Hirano M, Hosono H (2008) Iron-based superconductor La[O1-xFx] (x = 0.05-0.12) Tc 26 K. J Am Chem Soc 130:3296-3297.] was a real surprise and has generated tremendous interest. Although exists alloy that contains element Fe, LaOMPn (with M Ni; Pn P As) is first system where Fe plays key...
We have carried out a systematic study of the PbO-type compound FeSe_{1-x}Te_x (x = 0~1), where Te substitution effect on superconductivity is investigated. It found that superconducting transition temperature reaches maximum Tc=15.2K at about 50% substitution. The pressure-enhanced Tc FeSe0.5Te0.5 more than 10 times larger FeSe. Interestingly, FeTe no longer superconducting. A low structural distortion changes from triclinic symmetry to orthorhombic symmetry. believe this change breaks...
We use bulk magnetic susceptibility, electronic specific heat, and neutron scattering to study structural phase transitions in Fe$_{1+y}$Se% $_x$Te$_{1-x}$. Fe$_{1.068}$Te exhibits a first order transition near 67 K with tetragonal monoclinic simultaneously develops collinear antiferromagnetic (AF) responsible for the entropy change across transition.

This paper describes the design and synthesis of a photostable, far-red to near-infrared (NIR) platform for optical voltage sensing. We developed new, sulfonated silicon rhodamine fluorophore integrated it with phenylenevinylene molecular wire create Berkeley Red Sensor Transmembrane potential, or BeRST 1 ("burst"). is first member class NIR sensitive dyes that make use photoinduced electron transfer (PeT) trigger interrogation membrane voltage. show displays bright, membrane-localized...
Objectives: Cognitive impairment may interfere with psychosocial functioning in bipolar disorder (BD). There is limited information regarding the cognitive function of elderly patients onset at a young age. The present study aimed to investigate frequency and determinants early‐onset patients. Methods: Using Clock‐drawing Test (CDT), Mini Mental State Examination (MMSE), Abilities Screening Instrument (CASI), we examined euthymic I Taiwan, aged 60 years older. Clinical data were obtained by...
The recent discovery of superconductivity with relatively high transition temperature Tc in the layered iron-based quaternary oxypnictides La[ O1-xFx] FeAs was a real surprise. excitement generated can be seen by number subsequent works published within very short period time. Although there exists alloy that contains Fe element, LaOMPn (with M= Fe, Ni; and Pn=P As) is first system where Fe-element plays key role to occurrence superconductivity. has crystal structure an Fe-based plane. It...
A new approach to grow FeSe1−xTex single crystals with an optical zone-melting technique was successfully employed. Crystals actual composition 0.4 ≤ x 1.0 all show high crystallinity no phase separation. The ability visually observe the locally heated melt, and ease of use control image furnace make this method a promising time-efficient way for obtaining high-quality crystals. Our results indicate that adequate heat treatment, nonuniform distribution Se Te atoms in crystal lattice can be...

Although solid oxide fuel cells (SOFC) have demonstrated excellent performance, the durability of SOFCs under real working conditions is still an issue for commercial deployment. In particular cathode exposure to atmospheric air contaminants, such as humidity, can result in long-term performance degradation issues. Therefore, a fundamental understanding interaction between water molecules and cathodes essential resolve this further enhance durability. To study effects humidity on oxygen...
