- ATTENTION GOODLIFE!
- We have three new papers here, plus a report.
- Qiu et al used positron annihilation, a novel tool, to look for evidence of
- cnf, without success. Then Robert et al (again) describe their nifty fast
- neutron detector and set an upper limit to cnf at below Jones+ levels
- (although I am not sure where Jones+ levels now lie, after Kamiokande).
-
- The star of this update is Quickenden and our very own Green; this is Todd's
- Ph.D. work. He has done a good job and, while not getting down to Tom Droege's
- error levels, 1.5% is about the best that can be achieved with that kind of
- cell. This definitely goes into my "quality work" list, as a negative - Todd
- did not find any excess heat, neither in the short nor the long term; i.e. no
- bursts, no integrated excess. The measured points lie beautifully around the
- input power line, deviating by less than the known error. As the authors
- point out, if there IS an effect hidden by the noise level, then it is too
- small to be of interest. Good stuff, Todd, and I look forward to a paper on
- loading measurement.
-
- Finally, Bruce Lewenstein, lurking behind the scenes of this group, has
- studied the role of electronic media and written a report. As I don't put
- reports into my bibliography, this will not be archived but it might interest
- a lot of people, and Bruce is too modest (or is that lurky?) to tell you
- himself, so I include it below. Cold fusion features as an example, and
- although many people feel (I think) that email and fax played an important
- role in information dissemination in the field, there seems to be little
- concrete evidence that it has changed research patterns on the whole. Bruce
- must of course stick to what has been documented, but I think the report has
- underestimated the effect. Certainly a lot of people have benefitted from the
- easy access to information, and it has - I am sure - speeded up their research.
- You can get quick advice, for example, on how to use some technique - just ask
- whether anyone knows where to get, or how to use, some gadget, and someone is
- sure to know all about it. You "meet" people. I have yet to meet Terry, but
- we regard each other as friends, and the same goes for a number of people.
- These contacts are more than trivial, I have had good useful advice from Terry
- and Frank Close and Bill (lurk-mode) Johnson. I was even going to have a
- coauthor of a forthcoming paper, again someone I have met only by email. This
- did not work out but for other reasons than communication difficulties. These
- things are hard to document, though, and we can't blame Bruce for that. The
- report is no doubt available to anyone who wants it, just ask your librarian.

- "PAS studies on the new topic: Cold nuclear fusion".
- ** The behaviour of H and D in palladium hydride might be analogous to
- positrons in electric flows, so positron annihilation spectroscopy might be a
- useful tool. By this method, as well as by the electrochemical hydrogen
- permeation (EHP) method, the behaviour of H and D in Pd were compared. The Pd
- plates (15*15*2 mm**3) were annealed at 550 C for 8 h, and electrolysis
- carried out in 0.5 M LiOH/D for 5 h at 800 mA. An Ortec lifetime spectrometer
- with a fast-fast coincidence system and BaF2 detectors was used, with a (22)Na
- source, for 1E06 counts. Results are that H and D behave in nearly the same
- way; both change one of the PAS parameters (tau1) but this can be attributed
- to volume changes and not to crack formation, since the value recovered after
- final annealing. No cold fusion effects were observed.

- "A calorimetric study of the electrolysis of D2O and H2O at palladium
- cathodes".
- ** A very thorough calorimetric study, with 5 series of 4 experiments each,
- always comparing heavy and light water electrolysis in the same bath and, as
- far as possible, the same conditions. Variously (un)treated Pd rods and wires
- were used, in 0.1 M LiOH(D) and in one case 0.25 M Li2SO4. Gases produced were
- vented, so the cells were of the "open" type. Calorimetry was by means of a
- cooling coil, measuring the difference between inlet and outlet temperature.
- This kept cell temperature down and provided a very accurate calibration of
- cell power, independent of electrolyte volume. Charging was carried out prior
- to calorimetry, at low current to avoid fracturing of the palladium.
- Experiments were continued over a period of up to 6 weeks, and careful error
- analysis showed an error level in of 1.5% cell power. Results were within this
- limit at all times, so no excess (or deficit) heat was observed. Apr-92/Jan-93

- "Deuterated liquid scintillator (NE230) as a fast neutron detector for cold-
- fusion and other research".
- ** NE230 scintillator detectors with deuterium can provide neutron spectra
- without time of flight, unlike the type NE213. The authors report the use of
- these. They are small and and have good collection efficiency and n-gamma
- discrimination. One of these was used around a cold fusion electrolysis cell,
- with a Pd wire and a 13 g Pd casting. An upper limit for the fusion rate of
- <7E-24 fusions/s/dd-pair was measured. In another experiment, Ti sponge was
- charged from the gas phase at liquid nitrogen temperature, and here the upper
- fusion limit was <3E-24 fusions/s/d-d-pair. No comment is made.

- Report (not filed):
- ------------------------------------------------------------------------------
- Lewenstein B; Office of Technology Assessment, OTA Contractor Rept. 29-Dec-92,
- "The changing culture of research: Communication technologies and knowledge
- transfer".
- ** This examines the role of relatively recent communication technology such
- as telefax and email (and its offspring, bulletin boards or NEWS groups) on
- progress in science. The cold fusion saga is used as an example, and the
- sci.phycics.fusion NEWS group is under special scrutiny as an example. BL
- concludes that while there is increased awareness of developments, there is
- little evidence of increased collaboration between people as a result of these
- communication techniques. They will not replace face-to-face interaction.
- Nevertheless, researchers will increasingly require access to electronic
- media.
