Impact of Ethanol on Electrostatic Behaviour of Fluorocarbon Pharmaceutical Propellants [PDF]
PharmaceuticalsBackground/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.

Rubber Chemistry and Technology, 2019 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 ...

NON-DETONATING CHARGES IN POLYMER HOUSINGS FOR SMOOTH SPLITTING OF ROCK BLOCKS DURING PRIMARY EXTRACTION AND SECONDARY CUTTING [PDF]
Sustainable Extraction and Processing of Raw Materials Journal, 2020 . 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.

Indian Journal of Plastic Surgery, 2022 AbstractA propeller flap is an islanded flap that reaches the recipient site through an axial rotation around its vascular axis. The degree of rotation varies from 90 degrees to 180 degrees. It is a highly reliable local reconstructive option. These flaps are simple, single-stage, easy to harvest, and not constrained by routine length-to-width ratios ...
