“…However, the improvements have a certain distance from solving the mysteries of water for life. It has been introduced that water confined between quartz plates also exhibits anomalous behaviours at the approximate multiple of 15 °C 14 , 15 , and Drost-Hansen extended this idea to the room that the vicinal water anomaly (VWA) near solid surfaces has an important role in cell-functions and life 16 – 18 .

Water is essential for life. However, the structure and properties of water are still not well understood. It has been introduced that anomalies are in vicinal water near solid interfaces. We performed capillary flow experiments on water with a silica colloid sample using a high-performance liquid chromatography (HPLC) system by accurately varying the temperature and analysed the peak shape rigorously. We obtained a novel anomalous temperature spectrum from the peak-shape analysis. Here we report the observed distinct specific anomalous temperature (SAT) behaviour in vicinal water at silica interface. The anomaly appeared in the viscous force that was derived from a relationship between the shape of the HPLC peak and the velocity profile for the capillary flow. The observations were highly reproducible, and we conclude that the SAT is related to the quantum mechanical behaviour of water, in agreement of the characteristic acceptance of thermal displacement according to the Franck-Condon principle. We performed the same experiments using heavy water and water mixed with a small amount of methanol, and the results support the quantum phenomenological origin.

“…In the case of water, where even the data implying the disjoining force lie on the straight line, we have to realize that large effects cause the plot log Z versus h' to become insensitive to changes in AK. The peculiarity that the surface zone viscosity is rather enhanced though the disjoining force seems to be negligibly small for a flowing surface zone will be discussed in subsequent papers [31,32] which are mainly concerned with the temperature dependence of the surface zone viscosity of benzene and water, respectively.…”

The anomalies that appear at every multiple of 15 o C in the viscosity of a thin liquid film of water and of water near solid interfaces are explained in this paper by comparing the thermal wavelength and molecular free volume of water, and quantum numbers are found. The possibility that these anomalies are related to the preferred and/or lethal temperatures of organisms is considered. The toxicity of heavy water (D2O) can also be explained with this approach.
