Abstract
Some experiments have been performed to determine the effect on the friction coefficient of a little temperature increase caused by a small electrical resistance inserted in different ways in a ski or a ski-like device. It appears that at low speed this warming is able to reduce significantly the friction coefficient. The conditions of the experiments cover only reduced speed and temperature intervals. A possible interpretation of this phenomenon is based on the modification of the quasi-liquid-layer existing on the surface of snow at temperatures higher than −30°C. A wider set of parameter conditions should be analysed to confirm this interpretation.

期刊介绍：
The material innovations on surfaces, combined with understanding and manipulation of physics and chemistry of functional surfaces and coatings, have exploded in the past decade at an incredibly rapid pace.
Superhydrophobicity, superhydrophlicity, self-cleaning, self-healing, anti-fouling, anti-bacterial, etc., have become important fundamental topics of surface science research community driven by curiosity of physics, chemistry, and biology of interaction phenomenon at surfaces and their enormous potential in practical applications. Materials having controlled-functionality surfaces and coatings are important to the manufacturing of new products for environmental control, liquid manipulation, nanotechnological advances, biomedical engineering, pharmacy, biotechnology, and many others, and are part of the most promising technological innovations of the twenty-first century.
