The sliding wear of polymers against steel
… a friction reducing additive (UHMWPE/FILL), polyoxymethylene (POM), poly(ethylene terephthalate) (PETP), molybdenum disulphide filled polyamide 6 (PA6/MoS₂) and graphite filled poly(amide-imide) (P(A-I)/GR). Testing was carried out as a function of sliding velocity between 0.13 to 2.27 ms⁻¹, …

Investigations of the Processing-Structure-Property Relationships of Selected Semicrystalline Polymers
… (PMP), and the second was polyoxymethylene (POM). Three PMP resins were studied, which differed in weight average molecular weight. Three POM resins were also investigated where two of resins were characterized by relatively narrow molecular weight distributions (MWD) ca 2 …

High-resolution infrared spectroscopy in pursuit of C60 and other astrochemical targets
… astronomically relevant molecules, including the polyoxymethylene 1,3,5-trioxane. C60 was first discovered during experiments intended to simulate the conditions found in carbon stars, and has since been observed via emission spectroscopy in several planetary nebulae as well as the inerstellar …

Experimental investigation on the effect of the combustion of oxygenated fuels on the formation of soot
… formation under laminar coflow diffusion flames. Polyoxymethylene dimethyl ethers (PODE<sub>n</sub>) were chosen to be studied because they are one of the emerging class of oxygenated fuels for the transport industry. Up to 20% of PODE<sub>3</sub> was blended to ethylene to generate the flames to …

Development of an Intraruminal Controlled-Release Device
Slow-release devices retained in the rumen, are a simple method for continuous administration of bioactives to ruminant animals. To satisfy regulatory requirements and avoid waste of bioactive due to under- or over-dosing, it is advantageous to have a constant and predictable release rate. Existing …
