Nitrocellulose porosity - thermoporometry

Journal of Thermal Analysis and Calorimetry, 2003
Nitrocellulose porosity was investigated by thermoporometry, based on melting point depression of liquid in limited space. Strange behaviour of water-saturated nitrocellulose was observed, which consisted of melting peak shifting of some of liquid. Thermal resistance, connected with limited contact area of nitrocellulose walls and water, is supposed as

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

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 °

Nitrocellulose Membrane Art

2021
Several budding scientists and others have often attempted writing secret messages on paper, either for fun or sending secret messages to friends. These science nerds used lemon juice, milk, or other solutions that could be used with a dip pen, brush, or a fountain pen to write invisible messages on a blank white paper.

Degradation of nitrocellulose by fungi

Biodegradation, 2005
Three lignocellulolytic fungi, Trametes versicolor, Pleurotus ostreatus, and Coprinus cinereus, and two cellulolytic fungi Trichoderma reesei and Chaetomium elatum were tested for their ability to degrade nitrocellulose. They were provided with different carbon and nitrogen sources in liquid cultures.

Transmission densitometry of stained nitrocellulose paper

Analytical Biochemistry, 1988
We report a simple solution to the problem of quantitative densitometry of stained nitrocellulose paper. By immersing the paper in a household lubricating oil of matching refractive index, the light-scattering properties of the paper are largely eliminated, allowing precise transmission densitometry in any flat bed densitometer.

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

Brandversuche an Nitrocellulose-Zubereitungen

Materials Testing, 2003
. Formulations of nitrocellulose show already under the condition of an ignition by an external fire very high burning rates. In the case of storage the directives SprengLR 011 or SprengLR010 lay down test procedures to find the correct storage group and as a result of this protective and safety distances have to be considered.
