The role of chain scission and chain branching in high density polyethylene during thermo-mechanical degradation
(Elsevier B.V., 2004-12-01)
The mechanical and thermo-oxidative degradation of high density polyethylene (HDPE) was measured in a twin-screw extruder using various processing conditions. Two types of HDPE, Phillips and Ziegler-Natta, having different ...
Degradation analysis of the SnO2 and ZnO-based varistors using electrostatic force microscopy
(2013-06-01)
The degradation phenomena of ZnO and SnO2-based varistors were investigated for two different degradation methods: DC voltage at increased temperature and degradation with 8/20 μs pulsed currents (lightning type). Electrostatic ...

Vocal responses of austral forest frogs to amplitude and degradation patterns of advertisement calls
(Elsevier, 2017)
Degradation phenomena affecting animal acoustic signals may provide cues to assess the distance of emitters.
Recognition of degraded signals has been extensively demonstrated in birds, and recently studies have also
reported ...
Effect of particle size, iron ligands and anions on ciprofloxacin degradation in zero-valent iron process: application to sewage treatment plant effluent
(2017-09-01)
BACKGROUND: Ciprofloxacin (CIP) is an antibiotic largely used to treat bacterial infections and found in sewage treatment plant (STP) effluent. Zero valent iron (ZVI, Fe0) technology has great potential for the degradation ...
Probe-based qPCR assay enables the rapid and specific detection of bacterial degrading genes for the pesticide metaldehyde in soil
(2022-04)
Metaldehyde, a molluscicide pesticide, has been identified as a pollutant of concern due to its repeated detection in drinking water, thereby generating numerous compliance failures for water utilities. Biological degradation ...
TRIBROMOPHENOL DEGRADATION BY A CATECHOL-DRTVEN FENTON REACTION
(Sociedad Chilena de Química, 2009)
Using shifts in the electronic emission curve to evaluate polymer surface degradation
(Elsevier B.V., 2001-01-01)
The polymer surface degradation and/or modification evolution of Teflon FEP and Mylar C films caused by a low energy electron beam were analyzed using a new method that consists in measuring the second crossover energy ...
