Forensic scientists use various techniques to separate accelerants from fire debris samples before instrumental identification of added fuels. Among the choices available, traditional micro-distillation, steam distillation, vacuum distillation, headspace, heated headspace, and several vapor adsorption/desorption methods provide various advantages and disadvantages. This communication reviews th...

Background: The chemical composition and bioactivities of essential oils (EOs) of fingered citron (Citrus medica L. var. sarcodactylis (Noot.) Swingle) are considerably sensitive and lapsible during high-temperature processing of traditional separating techniques. In the present research, vacuum distillation and ultrafiltration were utilized in order to process the concentrated juice from finge...

A multilayered microfluidic chip used for vacuum membrane distillation is designed, fabricated and tested by rectification of a water-methanol mixture.

Koehler, G.D., Chipley, D. and Kyser, T.K., 1991. Measurement of the hydrogen and oxygen isotopic compositions of concentrated chloride brines and brines from fluid inclusions in halite. Chem. Geol. (Isot. Geosci. Sect.), 94: 45-54. Solutions of l-5 m NaCI, KCl, CaC12 and MgC12, and synthetic brines were analyzed for hydrogen and oxygen isotopic compositions by vacuum distillation-microequilibr...

Induction heating furnaces are employed for vacuum distillation process to recover and consolidate heavy metals after electrorefining operation. Induction heating furnaces of suitable heating rates are required to be developed for this purpose. Hence it is planned to set up a mock-up induction furnace which will simulate the conditions to be realized in actual induction heated vacuum distillati...

Poly (propylene fumarate) (PPF), a linear unsaturated polyester consisting of alternating propylene glycol and fumaric acid units, can be cured in vivo to fill the skeletal defects with minimal surgical intervention. Many different methods have been reported for synthesizing PPF, but none of them gives a clear method. The present paper introduces two new methods in PPF synthesis: Modified reflu...
