Preparation and characterization of nano NC/HMX composite particles

open access: yesScience and Engineering of Composite Materials, 2017
Nano nitrocellulose/cyclotetramethylene tetranitramine (NC/HMX) composite particles were precipitated from their co-solutions by the spray drying method. The nano composite samples were characterized by scanning electron microscope, transmission electron

Grafting of methyl methacrylate to nitrocellulose by ceric ions

open access: yes, 1979
Studies were carried out on grafting of various vinyl monomers to nitrocellulose by ceric ions. It was observed that graft copolymerization occurred only with methyl methacrylate (MMA) and methyl acrylate monomer.

Femtosecond laser ablation of nitrocellulose for spatio-temporal flow control in µPADs

open access: yesFrontiers in Physics
Microfluidic paper-based analytical devices (μPADs) are gaining popularity due to their low cost and ease of use, but controlling fluid flow for more complex biochemical assays within these devices remains challenging. This study investigates femtosecond

Ammonium Nitrate Coating with Nitrocellulose or the Inverse? A Study of the Coating Process and an Investigation of the Resulting Combustion Parameters

open access: yesApplied Sciences
This research focused on studying the issue of coating ammonium nitrate (AN) with nitrocellulose (NC) and its microcrystalline form (MNC), using two esterification methods: traditional (HNO3/H2SO4) and in situ synthesis (KNO3/H2SO4).

Detection and Molecular Mass Determination of an HIV Replication-Enhancing Female Genital Tract Factor Using a Blot Bioassay

open access: yesBioTechniques, 2000
We previously reported that cervicovaginal lavages (CVL) contain a factor that enhances the replication of human immunodefeciency virus (HIV) by increasing virus transcription in T cells and monocytoid cells. This factor was named the HIV-inducing factor

Laser-based patterning for fluidic devices in nitrocellulose

open access: yes, 2015
In this report, we demonstrate a simple and low cost method that can be reproducibly used for fabrication of microfluidic devices in nitrocellulose. The fluidic patterns are created via a laser-based direct-write technique that induces polymerisation of ...
