Abstract: The method of making a wall-coated open tubular capillary column with a poly benzyl stationary phase is a method of preparing a capillary column for gas chromatography. An inner wall of a fused silica capillary column is cleaned and then rinsed with a sodium hydroxide solution. The fused silica capillary column is flushed with isopropanol to form a pre-treated capillary column, and the pre-treated capillary column is loaded with a mixture of phenyl tri-methoxy silane and alcohol. The loaded pre-treated capillary column is heated to form a treated capillary column, which is then washed. A thin layer of a poly benzyl stationary phase is then coated on the inner wall through condensation polymerization of benzyl chloride monomers with a Lewis acid catalyst in a non-polar solvent.

Abstract: The endodontic point containing ultrasonic deformable material is a filler for root canal therapy that decreases in viscosity when subjected to ultrasonic waves. Once the point is inserted into a prepared tooth space, such as a prepared and cleaned root canal, the point is subjected to ultrasonic waves. The ultrasonic waves cause the viscosity of the point to lower, thus allowing the point to flow into voids in the tooth space and allow air to escape from the voids. The point then hardens and remains in the shape acquired when at low viscosity once application of the ultrasonic waves is stopped.

Abstract: The coupled borate/silicate salts-based additive for mortar or concrete controls chloride induced pitting and uniform corrosion of steel rebars embedded in the mortar or concrete with no detrimental effect on compressive strength of mortar/concrete. The silicate compounds may include one or more of the salts of sodium, potassium, lithium, calcium, magnesium, manganese, iron, zinc, aluminum and other transition and valve metals. The borate compounds may include one or more of the salts of alkali and alkaline earth metals, transition, non-transition and valve metals such as sodium, potassium, lithium, calcium, magnesium, manganese, iron, zinc, aluminum and others. The combination of the borate and silicate salts as an additive has been shown to impart high protection to steel rebar surfaces against corrosion, and particularly chloride induced pitting corrosion. The additives are equally effective for mortar as well as concrete.
