The title compound, a seleno-nium bromide, C(17)H(33)OSeSi(+)·Br(-), was obtained from the reaction of enanti-omerically pure 4,7,7-trimethyl-2-methyl-selanylbicyclo-[2.2.1]heptan-3-ol and (3-bromopropen-yl)trimethyl-silane in acetone. Due to the chiral bicyclic substituent, the crystal structure is not centrosymmetric and has no symmetry plane, with four chiral C atoms in the cation. The asymm...

In the title compound, C(12)H(28)N(+)·Br(-)·H(2)O, the ionic pairs formed by n-dodecyl-ammonium cations and bromide anions are arranged into thick layers; these layers are linked in a nearly perpendicular fashion [the angle between the layers is 85.84 (5)°] by hydrogen-bonding inter-actions involving the water mol-ecules. The methyl-ene part of the alkyl chain in the cation adopts an all-trans ...

Detergent-based mixtures and pure surfactants used as decontaminants in mass casualty scenarios were investigated for their acute 24 h toxicity. Commercial detergents Neodekont, Argos, Dermogel, and FloraFree were tested in male Wistar rats after percutaneous, peroral and intramuscular administration. Pure surfactants althosan MB, sodium alkylbenzene sulphonate, triton X, benzyl dimethyl dodecy...

Jewawut merupakan serealia pangan lokal non-beras yang telah lama didomestikasi di seluruh dunia termasuk Sulawesi Barat, Indonesia sebagai alternatif pengganti beras. Ekstraksi DNA tahap awal penting dalam analisis berbasis molekuler. Metode ekstraksi berpengaruh terhadap kualitas dan kuantitasnya dihasilkan program pemuliaan tanaman jewawut. Penelitian ini bertujuan untuk mendapatkan metode e...

In this research, effect of bicomponent mixed surfactant was studied on drop interface coalescence phenomenon in ambient temperature. First basic chemical system was water and toluene and 0.01 gr of sodium dodecyle sulfate (SDS) and the second basic system was water and toluene and 0.01 gr of cethyl trimethy amonium bromide (CTAB). Various weight fractions of second surfactant including 2-hepta...

Gold nanorods (AuNRs) are successfully employed in drug delivery, biosensors, and biotechnologies. Their wide success is due to their unique chemical properties, biocompatibility, easy, cheap versatile synthesis. In this framework, AuNRs were synthetized with the aim obtain strongly hydrophilic nanomaterials, suitable as delivery system. by seed mediated methods two steps. After careful purific...
