Impact of Ethanol on Electrostatic Behaviour of Fluorocarbon Pharmaceutical Propellants [PDF]
Background/Objectives: Triboelectrification in fluid systems, and specifically in hydrofluorocarbon (HFC)-based propellants, used in pressurised metered-dose inhalers (pMDIs) remains understudied despite its impact on aerosol behaviour and does delivery.

Effect of aging process on combustion and mechanical performance of nitroguanidine propellants [PDF]
The effect of different aging times (1 day, 3 days, 5 days and 7 days) on the combustion performance and mechanical properties of nitroguanidine propellants was studied.Through the mechanical properties test of impact and compression and closed bomb test

ABSTRACT Solid propellants are energetic materials used to launch and propel rockets and missiles. Although their history dates to the use of black powder more than two millennia ago, greater performance demands and the need for “insensitive munitions” that are resistant to accidental ignition have driven much research and development over the ...

THE PROPELLER AND THE FROG [PDF]
"Propellers" in planetary rings are disturbances in ring material excited by moonlets that open only partial gaps. We describe a new type of co-orbital resonance that can explain the observed non-Keplerian motions of propellers. The resonance is between the moonlet underlying the propeller, and co-orbiting ring particles downstream of the moonlet where

NON-DETONATING CHARGES IN POLYMER HOUSINGS FOR SMOOTH SPLITTING OF ROCK BLOCKS DURING PRIMARY EXTRACTION AND SECONDARY CUTTING [PDF]
. In some cases, during the extraction of certain mineral resources, industrial explosives are not sufficiently safe for the environment in terms of generated shock waves, toxic gases, seismic waves, scattering and vibrations.

Nitration of Chitin Monomer: From Glucosamine to Energetic Compound
The nitration of chitin monomer in a mixture of nitric acid and acetic anhydride was conducted and a highly nitrated (3R,4R,6R)-3-acetamido-6-((nitrooxy)methyl)tetrahydro-2H-pyran-2,4,5-triyl trinitrate (1) was obtained.
