I've taken many notes, but not sure if it is better than the abstracts, so I write just some teaser.
NB: most of the paper are teamwork, please read the abstract to understand who participated to what was presented.
The presentation of JP Biberian
https://iccf25.com/conf-data/iccf-25/files/ICCF25-book-of-abstracts_final.pdf#page=14
interested me much as it is experimental. He worked on 3 calorimeters, with quartz cell working up to 100°C, and the latest tries to increase power and temperature per watt by increasing thermal resistance (insulation), with 800g sample above 750°C. It seems to works well. Jacques Ruer worked on the design, to approach self sustainability.
previous calorimeter showed good results with a NiCu alloy base on nano Talcite (it is a common industrial compound, he explained), with hydrogen (1H).
smaller version showed power like 6W/100g powder, around 750°C... there seems to be a threshold around 350°C for the reaction.
Latest calorimeter show "encouraging" results, which seems to be the scientific term for "it works well, I alm happy, but let's check first I did not make a mistake".
It results are confirmed, and as I understand, replications may be interesting...

explains who they improved measurements on their NiCu+ H2/D2 nanomaterial, to measure photons in the IR (Fourier Transform IR) and UV range, to confirm heat measurement, and eventually detect strange gacts, like heat burst, short term oscillations, strange electrons behaviors...
The measure heat at desorbtion and quite much, for H2 and D2 (few MeV/atom sometime).
Peter Hagelstein representing Melvin Miles

explained the challenges and history of He4 measurement versus the heat... Very technical, but to read if you plan to measure He4.

Explained the unknow about the source of energy considered for some earthquakes, and proposes it may be LENR, and why it is possible (some reaction producing hydrogen, and metal hydrures).
Franz Tanzella

presented the calorymetry used to measure the performances of Brillouin reactor elements, from DC power to heat.
Not so simple because of the complex pulse electronics.
It's overunity from DC to heat, but not great as told in the presentation (numbers like 1.15).
Takeito Hito presented the work their team did (involving Clean planet and Tohoku university)
https://iccf25.com/conf-data/iccf-25/files/ICCF25-book-of-abstracts_final.pdf#page=16
where they measured photons (UV, Xrays, IR, visible)from their LENR experiments.
Analysing the transiends during heat burst, they discovered some precoursor events just before burst, that happens even during a burst.
A subject of further research !

Presented experimental results that seems to support his theory on constantan wires heated with hydrogen.
Using contactless thermography, he found a temperature threshold that match what he proposes theoretically.
Shinya Narita
https://iccf25.com/conf-data/iccf-25/files/ICCF25-book-of-abstracts_final.pdf#page=18
presented the work done at Iwate University, with excess heat observed
during H2 ou D2 desorbition in pd foils with various multilayers of PdNi, PdZr, NiPdZr, PdAg, PdTi.
Layers were added through Argon+ ion sputtering, about 100nm thick.
They observed also sample deformation, and proposed a theory to explain it, a phase transition of the H inside the Pd, leading to condensation and then LENR.
David Nagel

explained how he observed some strange coincidences about the isotopic transmutations resonance curves in unrelated experiments, the Widom-Larsen Optical Model, and the compilation of transmutations results made by Edmund Storms.
Something unexpected to understand ...
Volodymir Vystoskii
https://iccf25.com/conf-data/iccf-25/files/ICCF25-book-of-abstracts_final.pdf#page=19
described an experiments where heat waves at about 80MHz propagates to excite LENR, and have been generated by ultra sound and cavitation bubbles.
He3 and electrons are detected.
Harishyam Kumar

presented a theoretical work at Indian Institute of Technology Kanpur.
They created a simplified toy model for LENR, to see if it could be explained by a two step interaction, one at the chemistry level, on ate the nuclear level.
It would not explained LENR in the vacuum, but introducing constraints like in condensed matters, let some possible reaction rate to be expected.
With this good preliminary results on the toy model, they plan to work on a more realistic model.
Florant Metlzer

presented a collaboration in the context of Arpa-E strategy.
Their goal is to obtain irrefutable evidences, considering the field is stuck, with better evidences required while funding is missing.
Possible results may be excess heat above any possible chemistry, but it can always be dismissed. Otherwise good nuclar evidences, like neutrons, gamma, charged particle, istotopic shifts may convince.
They work on replicating some experiments, that is well defined, banal conditions, with active collaboration, and unambiguous products, to expect an chance of success.
They currently chose a gaz loading experiments with laser excitation, as replicated by Mastromatteo and JP Biberian already, producing neutrons, gamma, morphological changes and isotopic anomalies...
They consider some theoretical questions, the possibility of quantum coherent processes, transfer of energy in coupled oscillators, and connect their research to other research like quantum "superchemistry".
Tomotaka Kobayashi

presented work at Waseda University.
They tried to improve some experiments on Ni powder , by simultaneously applying pressure and heating.
It is improving the excess heat, and they work on a design of compression engine.
Francesco Celani

presented the work ar INFN for CleanHME project around the constantan wires.
they worked to simplify the design of their experiments, by basing the electronic on commercial and simple components,
and to make the treatments of the constantan wires more simple,
so it can be less expensive and easier to replicate.
It works, and they observed that the negative pusle excitation of their wires, is the most efficient, and exchange with M Staker make them consider it may be related to Super Abundant Vacancies theory of LENr as M Staker proposes. The way the constantan wires is placed make it looks like a coaxial line.
It appears the 0.45g of constantan produces currently up to 40W of excess heat.
NB: It is jus teasers, so you wait for the papers that will be published in JCMNS, or ask the authors as presented in the abstract book.
hard day.
