Mixtures containing ammonia-borane and sec-butylamine-borane remain liquid throughout the hydrogen release process that affords tri(N-sec-butyl)borazine and polyborazylene. Concentrated solutions with metal catalysts afford >5 wt% H(2) in 1 h at 80 °C and addition of (EMIM)EtSO(4) ionic liquid co-solvent eliminates competing formation of insoluble linear poly(aminoborane) (EMIM = 1-ethyl-3-meth...

The complex mol-ecule of the title complex, [Pd(C(16)H(23)N(2)OS)(2)], is completed by crystallographic twofold symmetry with the metal atom lying on the rotation axis. The Pd(II) atom exists within a slightly distorted square-planar geometry defined by a cis-O(2)S(2) donor set. The dihedral angle formed between the mean planes of the symmetry-related six-membered chelate rings is 12.88 (7)° an...

Objective Postpartum weight retention (PPWR), which refers to the value of postpartum minus pre-pregnancy weight, is a common problem among women after childbirth. The main objectives this study are understand changes in body breastfeeding mothers during long-term follow-up and preliminarily explore relationship between maternal human milk composition, including macronutri...

By surface modification of MFI microcrystals with sec-butanol and pre-coating the substrate with a temporary water layer, a convenient process is developed to directly assemble anisotropic MFI microcrystals into highly b-oriented monolayers on various substrates with different surface conditions.
