the oil content of the wax produced in a dewaxing process is the key economic parameter thatshould be reduced as much as possible. some factors such as the type of solvents, cooling rate,temperature, and solvent to oil ratio influence the dewaxing process. due to the fact that crude oildiffers from place to place and since the operational conditions for wax extraction vary for differenttypes of...

The main objective of this research is to investigate the effect of dewaxing and burnout temperature on the quality of copper alloy casting produced by a low cost block mold that has been developed. In the molding process, two types of silica sand which contains 97.9% silica (SiO2) and 97.2% silica have been used as a refractory material with POP served as a binder. Several mold formulations co...

Heat-induced epitope retrieval (HIER) is widely used for immunohistochemistry on formalin fixed paraffin-embedded tissue and includes temperatures well above the melting point of paraffin. We therefore tested whether traditional xylene-based removal of paraffin is required on sections from paraffin-embedded tissue, when HIER is performed by vigorous boiling in 10 mM Tris/0.5 mM EGTA-buffer (pH=...

It is shown that the introduction of nitrogen-containing monomer units, N-(dibutylaminomethyl)methacrylamide, into composition polymers higher alkyl acrylates increases their efficiency in process low-temperature solution dewaxing oil raffinates various compositions.

We present a new concept, termed tissue lithography (TL), and its implementation which enables retrospective studies on formalin-fixed paraffin-embedded tissue sections. Tissue lithography uses a microfluidic probe to remove microscale areas of the paraffin layer on formalin-fixed paraffin-embedded biopsy samples. Current practices in sample utilization for research and diagnostics require comp...
