In this study, the effects of ammonium hydroxide extracts from black tea on colon cancer cells were analyzed. Here we showed that black tea extracts decreased the growth of SW480 and HCT116 cells in a dose-dependent manner. The increase of subG1 population indicated that the black tea extracts induced cancer cell death. In addition, cell migration and invasion were significantly inhibited by th...

The title compound, C7H14N2Si, crystallizes in a tetra-gonal space group and exists as an N-H⋯N hydrogen-bonded tetra-mer, formed around the crystallographic fourfold rotoinversion axis. The mol-ecular identity is clearly the 5-tri-methyl-silyl-3-methyl-1H-pyrazole tautomer and the structure is isomorphous with that of 5-tert-butyl-3-methyl-1H-pyrazole [Foces-Foces & Trofimenko (2001 ▶). Acta C...

Stable flies are blood feeding parasites and serious pests of livestock. The immature stages develop in decaying materials which frequently have high ammonium content. We added various ammonium salts to our laboratory stable fly rearing medium and measured their effect on size and survival as well as the physical properties of the used media. The addition of ammonium hydroxide, ammonium phospha...

The title compound {systematic name: 2,2',2'',2'''-[3,7,11,15-tetra-aza-1(1,4),5(1,3),9(1,4),13(1,3)-tetra-benzena-cyclo-hexadeca-phane-3,7,11,15-tetra-yltetra-methyl-ene]tetra-benzonitrile}, C(64)H(56)N(8), is a centrosymmetric macrocycle that is consolidated into the crystal structure by C-H⋯π inter-actions.

The crystal structure of tetra-wickmanite, ideally Mn(2+)Sn(4+)(OH)6 [mangan-ese(II) tin(IV) hexa-hydroxide], has been determined based on single-crystal X-ray diffraction data collected from a natural sample from Långban, Sweden. Tetra-wickmanite belongs to the octa-hedral-framework group of hydroxide-perovskite minerals, described by the general formula BB'(OH)6 with a perovskite derivative s...

The title compound, (C(8)H(20)N)(2)[Cu(5)(C(7)H(4)NO(3))(4)(C(3)H(7)NO)(2)], abbreviated as (TEA)(2)[Cu(II)(12-MC(Cu(II) ) (N(shi))-4](DMF)(2) [where TEA is tetra-ethyl-ammonium, shi(3-) is salicyl-hydroximate (or N,2-dioxidobenzene-1-carboximidate) and DMF is N,N-dimethyl-formamide], contains five Cu(II) ions. Four of the Cu(II) ions are members of a metallacrown ring (MC), while the fifth Cu(...

For many reasons it is advantageous to collect urine separately and collection systems, so called "no-mix-toilets" exist. Therefore, this work deals with some methods to make use of this urine to produce value added products: IBDU and ammonia water. It could be shown that urea can be converted to IBDU only after concentrating urine. With air stripping and absorption ammonificated urine can be t...

The amination of aryl halides in the presence of inexpensive and air-stable alkali metal hydroxide bases and Pd[P(t-Bu)3]2 as catalyst gave arylamines in high yields. The reactions were conducted with a catalytic amount of cetyltrimethylammonium bromide as phase-transfer agent and either aqueous hydroxide or solid hydroxide in the presence of water. This combination of alkali metal hydroxide ba...

Urea formaldehyde resins were formulated with vatiables of three reaction pHs (1.0, 4.8, and 8.0 5.0) and three catalysts (sodium hydroxide, sodium hydroxide/ammonium mix, and triethanolamine) . The resins were prepared by placing all formaldehyde and water in reaction kettle and pH was adjusted with sulfnric acid and sodium hydroxide, respectively. Urea was added in 1.5 equal parts at 1 minute...
