Inside Cover: Solvent-Dependent Delamination, Restacking, and Ferroelectric Behavior in a New Charge-Separated Layered Compound: [NH4 ][Ag3 (C9 H5 NO4 S)2 (C13 H14 N2 )2 ]⋅8 H2 O (Chem. Asian J. 1/2017)

Dielectric and ultrasonic studies of new Ag0.1Cu0.9InP2S6 layered ferroelectric compound

The dielectric properties of newly synthesized Ag0.1Cu0.9InP2S6 crystals were investigated in broad frequency (20 Hz – 1 MHz) and temperature range (110 K – 350 K). Anomaly in the temperature dependence of a complex dielectric permittivity indicating the polar phase transition was detected at the temperature 283 K . The dielectric properties of the presented crystal are mainly caused by conduct...

Surfactant intercalated alpha-hydroxides of cobalt and nickel and their delamination--restacking behavior in organic media.

Dodecyl sulfate and dodecylbenzene sulfonate intercalated alpha-hydroxides of nickel and cobalt were synthesized by ammonia precipitation. These solids delaminate to give a colloidal dispersion of layers in organic solvents such as 1-butanol. The dispersed layers could be reassembled either by evaporation of the colloid or by coagulation by the addition of a polar solvent.

کاربرد کاتالیزوری wcl6 در سنتز : (1)14-آریل-h14-دای بنزو [a,j] زانتن 2)بنزایمیدازول

مطالعه wcl6 به عنوان یک کاتالیزور کارآمد در سنتز14-آریل-h14- دای بنزو [a,j] زانتن و بنزایمیدازولها به عنوان ترکیبات مفید و بیولوژیک.: سنتز14-آریل-h14- دای بنزو [a,j] زانتن و بنزایمیدازول ها، در حضور wcl6 به عنوان کاتالیزور و در شرایط بدون حلال انجام شد. از مزایای این روش عدم استفاده از حلال در محیط واکنش است که باعث سبز بودن کار است. در ضمن زمان این واکنش ها معمولا کوتاه و راندمان کـــار بالاست...

State-selected ion-molecule reactions: Charge transfer and atomic rearrangement processes in thermal energy collisions of H2+ (X;v)+N2 and of N2+ (X,A;v) + H2

Nonequilibrium processes in supersonic jets of N2, H2, and N2 + H2 mixtures: (II) shock waves.

We report an experimental study of the shock wave system of three continuous axisymmetric jets of pure N(2) and H(2), and of the N(2) + 2H(2) mixture, generated at p(0) = 1 bar and T(0) = 295 K through a D = 310 microm cylindrical nozzle against a background pressure p(b) = 6.1 mbar. Number density and rotational populations have been measured by Raman spectroscopy with high spatial resolution ...
