Francesco CELANI has given me permission to share this paper in the forum, just published after a long 'back and forth' with the referees in the proceedings of the IJCMNS. and on researchgate. It describes and discusses the results of over 80 experiments, and draws some important conclusions from the results, in particular the importance of flux - in terms of a changing environment - to stimulate the production of anomalous heat. I certainly think it a very worthwhile addition to the field's small store of knowledge about the triggering effect of what -in nuclear science terms - are trivial changes in gas pressure, EM fields, and also the role of heat flow (possibly related to thermoacoustics) and the ways in which this is helpful and not helpful.
I have certainly seen the 'flux effect' happen in quite different systems to those described here, but think that Francesco's 'knotty' method is both elegant, and while the wire is far from easy to prepare when ready it provides a robust workhorse for testing. Thoroughly recommended for a long-ish read.

This paper presents a summary and some deeper details about the experiments presented at the 22nd International Conference on Condensed Matter Nuclear Science (ICCF22). It reports on the experimental study of LENR phenomena in Constantan
(Cu55Ni44Mn1) from its inception in 2011 to the most recent experiments. Using an empirical approach we identified the effect of surface modification of the Constantan wires with coatings comprised of elements that enhance the absorption behavior,
and oxides with low work function for electron emission. We also explored certain geometrical arrangements of the wires such as knots and coils in order to induce local thermal gradients and predictable hot-spots. Moreover, the DC polarization of the wires by
a counter-electrode proved to be a versatile approach to induce non-equilibrium conditions that are essential for Anomalous Heat Effects (AHE), especially when a dielectric barrier discharge (DBD) is produced. From the review of experiments summarized in
this article, we obtain indications that the main parameter controlling the AHE is the flux of reactive species through the surface of the loaded material. As a consequence, all other external conditions of the reactor core (voltage–current, temperature, pressure,
electric field stimulations, DC and/or AC external fields), can be seen as co-factors that enable a flux of active species through surfaces and in the bulk of the materials. Although most of the tests are in agreement with a possible flux model, some results still
lack an interpretation, probably due to limits of the experimental setup.
