The aim of this work is to develop a methodology for the glide testing of waxed skis at an indoor ski centre, using artificial snow. Two skiers, one acting as a control with unwaxed skis, undertook the test runs over a 50-m course. Timing gates allow

The technique of mixed crystal FTIR spectroscopy has been applied to uniaxially drawn isotopic blends of linear polyethylene and ethylene copolymers. Following the drawing of melt-quenched samples at 1 mm min−1, clamped samples were cooled with liq

A mathematical approach developed to correct depth profiles of wet-chemically modified polymer films obtained by confocal Raman microscopy is presented which takes into account scattered contributions originated from a diffraction-limited laser focal

In contrast to the situation with early artificial turf pitches, little information has previously been published on the characterisation of third-generation artificial surfaces. The spatial variation of ball rebound resilience and rotational resista

The low temperature FTIR spectra of long chain n-alkanes C198H398 and C246H494, crystallised from solution in both extended and once-folded forms, have been investigated in the CH2 wagging region. Successive annealing and cooling stages result in a s

Confocal Raman microspectroscopy has many potential applications in the study of polymer-solvent interactions, including the determination of solvent and polymer-solvent complex depth profiles. This contribution focuses on preventing the formation of

Small angle neutron scattering (sans) has been used to observe changes in molecular orientation on deformation of isotopic, melt quenched blends of linear polyethylene and copolymers with butyl and hexyl branches, using uniaxial drawing. In no case w
