We have studied the hydrogen sorption on three well-known organic hosts that possess vacant lattice voids large enough to accommodate H2 molecules.

T3P/DMSO is shown to be an effective and mild reagent for the one-pot synthesis of furo[2,3-d]pyrimidine-2,4(1H,3H)-diones from a variety of alcohols. Alcohols are oxidized in situ to aldehydes under mild conditions, which undergo a three-component reaction with N,N'-dimethylbarbituric acid and various isocyanides to afford furo[2,3-d]pyrimidine-2,4(1H,3H)-diones in good yields.

Here, Pd nanoparticles supported on ZnO were prepared by the alcohol-reduction and borohydride-reduction methods, their efficiency towards photocatalytic conversion of methane under mild conditions evaluated. The resulting Pd/ZnO photocatalysts characterized X-ray fluorescence, diffraction, photoelectron spectroscopy, UV–Vis, transmission electron microscopy. reactions performed with dispersed ...

This paper is concerned with the existence and uniqueness of mild solution of the fractional differential equations with nonlocal conditions d q xt/dt q −Axt ft, xt, Gxt, t ∈ 0, T, and x0 gx x 0 , in a Banach space X, where 0 < q < 1. General existence and uniqueness theorem, which extends many previous results, are given.

The unique chemical properties of aryl trifluoromethyl sulfides (ArSCF3) have been known for over 60 years.[1] The capacity of SCF3 to act as a lipophilic electron-withdrawing group has resulted in the incorporation of ArSCF3 components into a number of pharmaceutical and agrochemical agents.[2] Unfortunately, direct access to this important class of compounds is complicated by a lack of effici...
