Pattern of a confined chemical garden controlled by injection speed

Atebrin by Injection vs. Quinine in a Tea-Garden Practice

Genericity of confined chemical garden patterns with regard to changes in the reactants.

The growth of chemical gardens is studied experimentally in a horizontal confined geometry when a solution of metallic salt is injected into an alkaline solution at a fixed flow rate. Various precipitate patterns are observed-spirals, flowers, worms or filaments-depending on the reactant concentrations. In order to determine the relative importance of the chemical nature of the reactants and ph...

Electronic and Optical Properties of Size-Controlled ZnO Nanoparticles Synthesized by a Facile Chemical Approach

Facile low-temperature chemical route for the synthesis of ZnO nanoparticles is reported in this paper. Morphologically uniform and spherical shape with an average particle size of 8.8 nm and wurtzite phase with the crystalline structure of as-synthesized ZnO nanoparticles were confirmed by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Transmissi...

Chemical Sterilization by Intratesticular Injection of Eugenia Caryophyllata Essential Oil in Dog: A Histopathological Study

Objective- To study a method of chemical sterilization and its efficacy in adult male dogs. Design- Experimental study. Animals- Ten healthy adult mixed breed dogs Procedures- Eugenia caryophyllata (EC) essential oil was injected into the dorsal cranial portion of each testicle of five dogs (treatment group). The same volume of normal saline was injected in the same site of testicles in the ...

Embryo Transfer with Controlled Injection Speed to Increase Pregnancy Rates: A Randomized Controlled Trial.

BACKGROUND/AIMS Catheter injection speed affects depth and placement of the embryo into the uterine cavity and is shown to be highly variable in, and between, subjects in a manually performed embryo transfer. In an effort to standardize the injection speed during embryo transfer, we developed an automated transfer pump: the pump-regulated embryo transfer (PRET) device. In this randomized contro...
