TL;DR: In this article, the gas adsorption properties of a zinc based metal organic framework, (Zn 2 (bdc) 2 (dabco)(H 2 O) 0.5 (DMF) 4 ), more commonly known as ZnDABCO, were reported.

TL;DR: A one-pot, tandem process has been developed for the synthesis of a library of tetrazoles from aryl isothiocyanates, where Aryl-sec-alkyl unsymmetrical thioureas gave thioamido guanidino products rather than the 5-aminotetrazoles produced by HgCl(2) mediation of the reaction.
Abstract: A one-pot, tandem process has been developed for the synthesis of a library of tetrazoles from aryl isothiocyanates. Condensation of aryl isothiocyanates with ammonia, and aryl amines (R-NH2) provided mono, 1,3-disubstituted symmetrical and unsymmetrical thioureas, which on desulfurization with molecular iodine (I2) led to formation of the corresponding heterocumulene (cyanamides or carbodiimides). The in situ generated heterocumulene on subsequent treatment with sodium azide at room temperature gave corresponding tetrazoles. The product regioselectivity for unsymmetrical 1,3-disubstituted thioureas was found to be correlated with the basicities (pKa's) of the parent amines attached to the thiourea. Aryl-sec-alkyl unsymmetrical thioureas gave thioamido guanidino products rather than the 5-aminotetrazoles produced by HgCl2 mediation of the reaction. Bis-thioureas derived from aryl isothiocyanates and hydrazine gave thiadiazoles exclusively.

TL;DR: Experimental results show that in terms of haemolytic activity the PVA/Cs/Ar and PVA-Cs/O2 nanofibers do not cause structural changes of blood cells and meet the biocompatibility requirements for blood-contacting polymeric materials.

TL;DR: In vitro biological results reveal that the blended hydrogels provide an ideal 3D matrix for primary rat islets and the immuno-informed hydrogel demonstrates local modulation of inflammatory responses in vivo.

TL;DR: No evidence for processes in the mass range m(A⁰) ≤ 9.2 GeV and m(χ) ≤ 4.5 GeV is found in the sample of 98 × 10⁶ Υ(2S) decays collected with the BABAR detector and stringent limits on new physics models that contain light dark matter states are set.
Abstract: We search for single-photon decays of the Υ(1S) resonance, Υ → γ + invisible, where the invisible state is either a particle of definite mass, such as a light Higgs boson A^0, or a pair of dark matter particles, χχ . Both A^0 and χ are assumed to have zero spin. We tag Υ(1S) decays with a dipion transition Υ(2S)→π^+π^-Υ(1S) and look for events with a single energetic photon and significant missing energy. We find no evidence for such processes in the mass range m_(A^0 ≤ 9.2 GeV and m_χ ≤ 4.5 GeV in the sample of 98×10^6 Υ(2S) decays collected with the BABAR detector and set stringent limits on new physics models that contain light dark matter states.
