摘要

使用磁性处理的水和未处理的水进行了薄层芯吸实验。两种不同结构和磁场强度的磁铁（B=15 mT和B=0.27 T）使用。研究发现，在磁场存在下循环的水更快地渗透到硅胶的多孔层中。这也反映在根据van Oss等人的方法计算的硅胶的表面自由能的电子供体和电子受体参数的变化中。基于这一发现，假设水结构发生了变化，即水流以某种方式破坏了液态水中的氢键网络，而磁场作用促进了其形成。

Thin layer wicking experiments using magnetically treated water

Thin layer wicking experiments were carried out using a magnetically treated water and non-treated one. Two types of magnets of different construction and strength of the magnetic field (B=15 mT and B=0.27 T) were used. It was found that water circulated in the presence of magnetic field penetrated faster into the porous layer of silica gel. This is reflected also in the changes of electron donor and electron acceptor parameters of the surface free energy of the silica gel as calculated from the van Oss et al. approach. Based on this finding it is hypothesized that changes in the water structure occurs, i.e. the water flow destroys somehow the network of hydrogen bonds in liquid water while the magnetic field action promotes its formation.

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.
