Temperature effects on the birefringence of nitrocellulose and nitrocellulose/nitroglycerine mixtures

Polymer, 1985
Abstract Changes in the optical path difference of nitrocellulose fibres of varying degrees of substitution over the temperature range −120°C to 130°C are interpreted as due to conformational changes in the primary nitrate group. Changes in path difference of nitrocellulose/nitroglycerine paste fibres over the same temperature range indicate an ...

Kinetics of the Alkaline Hydrolysis of Nitrocellulose

Water Environment Research, 2001
Cellulose nitrate (nitrocellulose) is an explosive solid substance used in large quantities in various formulations of rocket and gun propellants. Safe destruction of nitrocellulose can be achieved by alkaline hydrolysis, which converts it to biodegradable products that can then be treated by conventional biological processes.

Biodegradation of nitrocellulose

Journal of Energetic Materials, 1995
Abstract The research carried out in the past on the microbial degradation of nitrocellulose produced conflicting results primarily due to the lack of a proper analytical method for nitrocellulose estimation. Using an acetone extraction method, with appropriate corrections, Brodman and his coworkers concluded that certain fungal cultures are capable of

The Rheological Properties of Plasticized Nitrocellulose as a function of nitrocellulose precursor

Propellants, Explosives, Pyrotechnics, 1988
AbstractPropellant cords have been manufactured from nitrocellulose/nitroglycerin (50/50) pastes containing different types of nitrocellulose. The cords were manufactured using a solvent wet process involving incorporation and extrusion in the highly instrumented propellants processing facility at Waltham Abbey.

Mechanochemical effects in degradation of nitrocellulose and nitrocellulose–diphenylamine mixture

Thermochimica Acta, 2005
Abstract Dynamic mechanical analysis is combined with mass spectrometry to study nitrocellulose and nitrocellulose–diphenylamine films under oscillating strain. At a constant temperature (150–160 °C) and frequency 400–600 Hz nitrocellulose fractures demonstrating a modulus drop and release of products with m / z  = 30 and 44. At a linear heating (2 °

Adsorption of dactinomycin to nitrocellulose filters

Experimental Cell Research, 1973
Abstract Dactinomycin is strongly adsorbed to nitrocellulose filters and some of the adsorbed material is slowly released. This affects both the growth and development of embryonic explants and the nucleotide incorporation of HeLa cells cultivated on pretreated filters.

A RHEOLOGICAL STUDY OF SOLUTIONS OF NITROCELLULOSE

Canadian Journal of Research, 1948
By using a MacMichael viscometer the change in viscosity at various rates of shear was determined for solutions of various types of nitrocellulose in the solvents; acetone, n-butyl acetate, Hercules' mixed solvent, and dibutyl phthalate. It was found that all solutions of low intrinsic viscosity nitrocellulose were dilatant in dilute solution, while ...

Nitrocellulose Membrane: The New Canvas

2015
The use of nitrocellulose membranes for invisible ink-messaging or marking for orientation purposes has been carried out with diluted alkaline phosphatase, followed by development with nitro blue tetrazolium/5-bromo-4-chloro-3-indolyl phosphate and chemiluminescence detection systems. Here, we show that nitrocellulose membrane can serve as a canvas for

Measuring Protein Concentration on Nitrocellulose and After the Electrophoretic Transfer of Protein to Nitrocellulose

2015
Proteins bind to nitrocellulose membranes when applied directly or after electrophoretic transfer from polyacrylamide electrophoresis gels. Proteins can be stained for visualization with organic dyes Ponceau S, amido black, Coomassie Blue, and colloidal silver/gold and the intensity of the stain is directly proportional to the amount of protein present.
