This study reports the synthesis of morphology-controlled BaTiO(3) nanostructures such as spherical, cube-shaped and rod-shaped BaTiO(3) using a molten-salt synthesis method. This method synthesized products from a reaction of BaO/BaCO(3) and TiO(2) with a eutectic mixture of NaCl-KCl flux at 700 degrees C for 1 h. The experiment used powder X-ray diffraction, field emission scanning electron m...

In this study, the effect of nanoparticle concentration was tested for both CuO and TiO₂ in eutectic mixture of sodium and potassium nitrate. Results showed an enhancement in specific heat capacity (Cp) for both types of nanoparticles (+10.48% at 440 °C for 0.1 wt % CuO and +4.95% at 440 °C for 0.5 wt % TiO₂) but the behavior toward a rise in concentration was different with CuO displaying its ...

Background: Venous cannulation is the most commonly performed invasive procedure in hospital patients. It is painful and associated with a high incidence of vasovagal reactions and pressor responses in patients. Objectives: The aim of the study is to evaluate the efficacy of eutectic mixture of local anesthetic cream in producing dermal analgesia for venous cannulation. Material and Method: 200...

Volcanic edifices are abundant on rocky bodies of the inner solar system. In the cold outer solar system, volcanism can occur on solid bodies with a water-ice shell, but derived cryovolcanic constructs have proved elusive. We report the discovery, using Dawn Framing Camera images, of a landform on dwarf planet Ceres that we argue represents a viscous cryovolcanic dome. Parent material of the cr...

conclusions this study does not support the use of emla for hsg. results there was no significant difference in the efficacy between emla and placebo creams in pain perception during the entire procedure. there was no significant difference in long term pain perception half an hour after the hsg performance. patients and methods eighty patients undergoing hsg as part of infertility evaluation w...

Class-obtained melting points were used to create a melting point diagram of naphthalene and biphenyl. The eutectic point was estimated by extrapolation to be at 45 mole percent naphthalene. Unknown “A” was determined to be benzophenone by mixed melting point method. Introduction Melting points are used to help determine the purity and identification of solids. A melting point is the temperatur...

Solubility is the phenomenon of dissolution of solid in liquid phase to give a homogenous There are many techniques which are used to enhance the aqueous solu aqueous solubility can thus be a valuable aid to increasing efficiency and/or reducing side effects for drugs. This is true for parenterally, topically and orally administered solutions. used for the improvement of the solubility of poorl...

Objectives: The objective of this study was to confirm the ability of EMLA(R) cream (Eutectic Mixture of Local Anaesthetics, Astra, Sweden) to provide effective dermal analgesia after topical application on the skin of the dorsum of the hand 1 h before venous cannulation for anaesthetic induction. Material and Methods: Prospective, randomized, double blind study. We included 100 children, ASA I...

A prospective controlled trial was conducted to compare the efficacy of an analgesic cream (eutectic mixture of local anesthetics, or EMLA) with a combination of EMLA with hypnosis in the relief of lumbar puncture-induced pain and anxiety in 45 pediatric cancer patients (age 6-16 years). The study also explored whether young patients can be taught and can use hypnosis independently as well as w...

Part 2 of this paper deals with the techniques for drug delivery of topical and injectable local anaesthetics. The various routes of local anaesthetic delivery (epidural, peripheral, wound catheters, intra-nasal, intra-vesical, intra-articular, intra-osseous) are explored. To enhance transdermal local anaesthetic permeation, additional methods to the use of an eutectic mixture of local anaesthe...
