Glass-phase coordination polymer displaying proton conductivity and guest-accessible porosity

We describe the preparation of the crystalline and glassy state of a coordination polymer displaying proton conduction and guest-accessible porosity. EXAFS and solid-state NMR analyses indicated that pyrophosphate and phosphate ions are the main proton transporters in the glass and that homogeneously distributed 5-chloro-1H-benzimidazole in the glass provide the porosity

Siloxane D4 capture by hydrophobic microporous materials

Porous substances, including crystalline coordination materials and an amorphous organic polymer, were studied for their selective adsorption of siloxane D4. The investigated materials demonstrated a level of uptake comparable to that of conventional activated carbon

Polarization superposition of room-temperature polariton condensation

Abstract A methodology for forming a qubit state is essential for quantum applications of room temperature polaritons. While polarization degree of freedom is expected as a possible means for this purpose, the coupling of linearly polarized polariton condensed states has been still a challenging issue. In this study, we show a polarization superposition of a polariton condensed states in an all-inorganic perovskite microcavity at room temperature. We achieved the energy resonance of the two orthogonally polarized polariton modes with the same number of antinodes by exploiting the blue shift of the polariton condensed state. The polarization coupling between the condensed states results in a polarization switching in the polariton lasing emission. The orthorhombic crystal structure of the perovskite active layer and/or a slight off-axis orientation of the perovskite crystal axis from the normal direction of microcavity plane enables the interaction between the two orthogonally polarized states. These observations suggest the use of polariton polarization states as a promising room temperature quantum technology

Intraluminal Apple as a Rare Cause of Small Bowel Obstruction

Small bowel obstruction due to ingested foreign bodies is rare in adults. A 48-year-old male visited our hospital with abdominal pain and vomiting. Computed tomography revealed intestinal obstruction by a 3 × 4 cm apple-shaped foreign body. Emergency surgery was performed to clear the obstruction which, upon inspection, was caused by a sexual toy made of rubber. Flexible rubber products that are ingested should be carefully followed after they pass thorough the pylorus. For obstructions related to sexual behavior, the patient’s sense of shame often delays the process of seeking medical attention, thereby making preoperative diagnosis difficult

Postsynthesis Modification of a Porous Coordination Polymer by LiCl To Enhance H⁺ Transport

A Ca²⁺ porous coordination polymer with 1D channels was functionalized by the postsynthesis addition of LiCl to enhance the H⁺ conductivity. The compound showed over 10^–2 S cm^–1 at 25 °C and 20% relative humidity. Pulse-field gradient NMR elucidated that the fast H⁺ conductivity was achieved by the support of Li⁺ ion movements in the channel
