Hello all,
a small offering here, out of electrochemical journals. Czerwinski and Marassi
have previously published a paper on results in acidic solution, now they have
gone basic. Some of their conclusions will not surprise anyone, such as, that
loading is potential dependent (current is potential dependent, too). However.
Sioda has published a small calorimetric paper before; Fahidy is well known as
an electrochemically inclined chemical engineer, and the two have written on
an engineering-approach to calorimetry calculations, which might help
calorimetrists. The Italian team, Mengoli et al, continue to look for tritium
and neutrons; their neutron detector was none too good and any signal is
buried in the noise. They try for nonequilibrium by an asymmetric current
feed, but this did not pan out. Some tritium was found but not enough to run
screaming from your bath.
 Then there is a Science note, commenting on EPRI's support of cold fusion;
it's not as much as $12M, as sometimes stated.
 Note that the three "real" papers plus my previous count of 698 add up to
700, not 701; I found that last week's posting of the Jin et al paper was a
repeat, i.e. I had it already, so that should have been 697. So anyway, we are
now back at the 700 mark, even without the patents.

"The absorption of hydrogen and deuterium in thin palladium electrodes.
Part II: Basic solutions".
** A report of the potential dependence of the amount of hydrogen/deuterium
sorbed in a thin Pd film (supported on Au) in basic solutions of different
electrolytes (NaOH, LiOH, NaOD, LiOD, all 0.1 M). It appears that Li+ ions
favour absorption but hinder desorption of hydrogen/deuterium, with respect to
Na+. Cyclic voltammetry was carried out, and the results show that absorption
is strongly potential dependent, that basic electrolytes behave differently
from acidic electrolytes, Li+ ions seem to affect the alpha-beta transition
more than Na+ ions, maximum H(D)/Pd ratios are not affected by the electrolyte
composition, and that sorption causes irreversible changes in the palladium.

"Tritium and neutron emission in D2O electrolysis at Pd and Ti cathodes".
** Previous work by this team, in which some evidence of tritium was found,
indicated that large cathode area would be favourable, as would be some sort
of nonequilibrium. Here, this is followed up with larger Ti and Pd plates,
rods and tubes, with the geometry providing asymmetric electric fields for
nonequilibrium (unequal current densities over the cathode surfaces). The Ti
was cleaned prior to use in either boiling 20% oxalic acid (3 min) or 5% HF,
to remove the blocking oxide layers; Pd was dipped in 5M HCl to remove traces
of contaminant metals (Fe, Cr, etc). Tritium was looked for in the electrolyte
and evolved gases; tritium in the cathodes was believed to appear in these
phases eventually, so was not looked for in the metals. Neutrons were detected
by a single scintillation counter, in a constant temperature room, regarded as
important; pulse height discrimination was used; overall efficiency was
0.3-0.35%. No significant neutrons were found, and none correlating with
tritium peaks. This is probably due to the high background of above 100 c/s.
Tritium enrichment was observed, but could not account for all of the tritium
found, even if an infinite separation factor is assumed; no relationship
(other than one negative one) between current and tritium produced could be
discerned. Some tritium deficit was observed as well and put down to
evaporation loss. What tritium excess was found appeared early in the
electrolysis at Ti, in conformity with a near-surface effect.    Jul-91/Jan-92

"A simplified approach to the thermal behaviour of electrolytic Dewar cell
calorimeters"
** Calorimetry is central to much of cold fusion research, and has been dogged
by problems. In this paper, the authors describe a simplified thermal analysis
in terms of a single nonlinear thermal balance for the prediction of
temperature time variations in such cells. The overall heat loss coefficient
can be estimated accurately. The model can be reduced to a simple one, or made
more complex. In the simplest case, constant input power is assumed, as well
as constant radiative emissivity and emission area for both source and sink.
The heat balance differential equation can then be solved, and numbers are
tabulated as examples. Varying input power is also allowed. Results show that
heat loss can be estimated experimentally and this may help decide whether
excess heat is produced.                                         May-91/Apr-92

"Propping up cold fusion" (Random Samples section).
** A report of the support EPRI continues to give cold fusion, by financing
McKubre's group. Despite the explosion, which killed one group member and
injured others, the work will go on. EPRI revealed on 19-Mar that more funds
would be given to SRI (where the work is done) but not - as some have claimed
- $12 million. The actual figure will be reviewed from time to time. The
project is titled "Excess heat production in electrolytic experiments
involving palladium as the host metal for deuterium"; the term "cold fusion"
does not appear.
