This paper reports an investigation of liquid *and *alloy correlating XRD and viscosity measurements to highlight
temperature dependent transformations in the liquid structure.
The main result is based on ***which is interpreted as
providing an evidence for a ***l structure.
While the overall experimental work is probably valuable I have
strong objections on the data presentation,interpretation,
discussion and conclusions and I cannot recommend publication
of the present manuscript.
Regarding the***analysis the authors ***.This is rather obvious and implicit in eq.(5),so extensive
presentation of tabulated and plotted data for Dcd is unjustified.
It must be 3 within numerical uncertainties.Regarding the region***,
which displays an exponent intermediate between 2 and 3,it is
limited to a narrow distance region between the first two peaks
of the g(r),so,referring this exponent as a ***completely misleading.These fluids are homogeneous and
a sub-3 power law behavior in this narrow region only reflects
the existence of a minimum in the g(r)after the first neighborpeak.The increasing value of ***with T just
reflects the tendency of any structure correlation to wash out
with temperature.
The authors claim the existence of ***with T.
The first evidence comes from Fig.4 and 5,but the parameter
rc is biased by its definition(eq.(6)).It is clear that
upon increasing T the condition(6)(which involves g(r)and
not the envelope of the oscillating part)will jump by an
integer number of half oscillations.This analysis should be
performed with an exponential fitting of the oscillation amplitude
of g(r)-1.The”jumps”displayed by the***data
of Fig.11 and 12 are within the 5%error stated in Sec.2.3.
The viscosity data for the***alloy Fig.13 display a 30%
decrease between 200 and 300 C,but the T range is di?erent
from the change in the exponent shown in Fig.9.
On the basis of these consideration I find all the claims for
discontinuous changes with T and all the proposed models
rather speculative.
For all the above reasons this paper should be rejected.
The authors are however encouraged to perform a proper analysis
of their data using using unbiased parameters like an exponential
correlation length.The short range order may be characterized by
a power law exponent but the claim for a fractal order is not
appropriate.Looking for a correlation between short range order
and viscosity is reasonable but it should not be biased by the
search for discontinuous changes.Usage of the English language and
scientific terminology should be improved:in Sec.2.2 and 3.1 the
RDF is often referred to as”Radical distribution function”instead
of”Radial”.Meaningless terms like”catamaran correlation”at pag.6
or”European Space”at pag.11,just to mention a few cases,are used.
A completely rewritten paper may be considered for publication but
other Journals in condensed matter physics are probably a better target.
