We have performed Pd electrodeposition in both D2O and H2O electrolytes in the presence of a magnetic field using CR-39 solid state nuclear track detectors. These detectors were either immersed in the electrolyte or separated from it by a thin Mylar® film. We have found a statistically significant increase in the number of tracks measured in the D2O experiments when compared to the H2O experiments.

BET adsorption, electron-microscopy, and X-ray diffraction analysis have been employed to study the vibrodispergating kinetics of crystalline lithium fluoride particles under conditions of simultaneous irradiation of the material with a flux of thermalized neutrons with low intensity I = 100 neutron/(cm(2) s). It has been found that, during vibratory treatment of the powder, the stationary state of the material microstructure is reached much earlier than the limiting (equilibrium) value of its external (specific) surface area is established. The reaction rate constants have been determined for the polygonization and recrystallization, which take place in the material during its vibratory grinding. The influence of the neutron irradiation on the numerical values of these constants has been revealed. The energy parameters of the processes occurring in the system have been analyzed taking into account the heat release caused by neutron absorption in the material.

Columbia Resin-39 (CR-39) detectors used in Pd/D co-deposition experiments were examined using an optical microscope, scanned using an automated scanner, and underwent both sequential etching analysis as well as LET spectrum analysis. These analyses identified and quantified the energetic particles responsible for the tracks observed in the CR-39 detectors and made it possible to estimate the branching ratios of the primary and secondary reactions.

The distribution of hydrogen in the palladium matrix and single-wall carbon nanotubes (SWCNs) in Pd-SWCN nanocomposite upon electrochemical hydrogenation is quantitatively studied in situ using voltammetry and chronoammetry. The high mobility of hydrogen in nanotubes is discovered and reflected in the low H-SWCN bond energy, which equals 0.073 ± 0.05 eV/H-atom and is close to the hydrogen activation energy (ɛ H = 0.072–0.08 eV/H-atom) obtained using vacuum thermal desorption [7]. The presence of SWCN is shown to increase the hydrogen capacity of the Pd-SWCN composite compared to individual palladium by nearly 25%. The hydrogen storage capacity of nanotubes ( C H ) in Pd-SWCN composite increases with an increase in the Pd-to-SWCN volume ratio ( V (Pd)/ V (SWCN)). C H reaches the maximum limiting value of 12 wt % at V (Pd)/ V (SWCN) > 12.

Abstract. We have reported [1] the detailed analysis of the CR-39 detector (Landauer) from SRI’s #BE013-7 (#7) Pd deposition experiment where the detector was separated from the cathode wire by a 6 μm Mylar film. The Mylar protected the CR-39 surface from chemical, mechanical, and electrostatic (spark discharge) damage during electrolysis. Inthis report we compared those results with that of the CR-39 detector, installed as in #7, in an identically operated cell using light water and with the background detector placed 2 m from the electrolytic cell.

Experimental data on enhancement of the yield of DD/DT reactions in metal targets at low energies of projectile deuterons ( E d < 5 keV) were analyzed. A semiempirical expression was obtained to describe the dependence of the screening energy for deuterons upon the effective number of mobile deuterium atoms on the target metal surface. Numerical estimates showed that the edge plasma effects in ITER-type fusion reactors can be an additional source of generation of α-particles and of the buildup of 4 He atoms in first-wall and divertor materials.

We report a study of hydrogen storage in an alternative material, representing single-walled carbon nanotubes (SWCNTs) encapsulated by thin Pd layers onto a Pd substrate. A synergetic effect resulting in combination of the Pd and the SWCNTs properties with regards to hydrogen has been achieved. Adding SWCNTs increases the H(2) capacity of the Pd-SWCNT composite by up to 25% relative to Pd metal alone under electrochemical loading. This results in a storage capacity of 8-12 wt %. with regard to the added SWCNTs.

The nature of paramagnetic centers in a nanostructure based on single-walled carbon nanotubes (SWCNTs) encapsulated with Pd was studied by EPR spectroscopy at 77 and 293 K. It was found that strong charge-transfer π complexes of the (Pd-C x ) type, which manifested themselves as a narrow resonance (Δ H = 6–8 G and g = 2.002 at T = 77 k), were formed in the Pd-SWCNT composite along with impurity centers (Fe 3 O 4 nanoparticles within the nanotubes), which were responsible for a broad EPR signal (Δ H = 75 G and g = 2.065 at T = 293 K). These complexes were found to be predominant adsorption sites responsible for a high gravimetric density of hydrogen (H/C ≥ 1.0) within the single-walled carbon nanotubes.

Condensed matter nuclear effect, especially 4D-cluster fusion, in metal-deuterium complex systems, has been studied by applying Langevin equations. One dimensional Langevin equations for solving time-dependent d-d distance Rdd(t) for deuteronclusters under the Platonic symmetry were formulated for D-atom, D2 molecule, D2 ion, D3 ion, 4D/TSC and 6D/OSC. Established values of ground state d-d distances Rgs were reproduced by expectation-value equations, which were obtained by ensemble averaging with weight of quantum mechanical wave functions (Gaussian wave functions), for D-atom, D2, D2 , and D3 + molecules. In analogy to above Langevin equations, the Langevin equation for 4D/TSC under the tetrahedral double Platonic symmetry was derived and numerically solved by the Verlet time-step method. It was shown that only 4D/TSC among 5 D-systems except D-atom could condense ultimately from Rdd(t=0)=74 pm to very small charge neutral entity with about 10 fm radius at TSC-min state after about 1.4 fs condensation time. The 6D/OSC system converged at Rgs=about 40 pm, namely converged on the way of condensation from Rdd(t=0)=74 pm. Time-dependent Coulomb barrier penetration probabilities (barrier factors) for condensing 4D/TSC were calculated by the Heavy Electronic Quasi-Particle Expansion Method. 4D fusion rate per TSC generation was obtained based on the Fermi’s first golden rule to result in almost 100% 4D fusion per 4D/TSC generation. Fusion rates were compared with those of muonic dd molecule, D2 molecule and dde*(2,2) Cooper pair molecule to meet good consistency. Major nuclear products of 4D fusion are two 23.8 MeV α-particles. 4H/TSC should condense in the same way until when TSC-min state with classical electron radius (2.8 fm) comes, but no strong interaction exists among protons and will make 1p to 4p capture transmutations with host metal nuclei when 4H/TSC has sufficient drift (CMS) momentum. 1) A.

We examined now an ultraweak thermalized neutron field (UTNF) affects the structural transformation in DNA macromolecules at room temperature. IR-spectroscopy, electrophoresis, and filtration through nitrocellulose filter measurements revealed that UTNF irradiation with a fluence of F(n) - 1.0 - 3.7 x 10(7) n/cm2 (the absorbed dose as low as 10 - 50 microGy) can induce non negligible structural changes in DNA macromolecules in film as well as in an aqueous solution. These structural changes appear as a type of reversible conformational transition from the A-form to a disordered state, as well as through intermolecular cross-link formations and the generation of double-strand breaks.

Weak nuclear emissions accompanied deuterium loading/deloading into Ti and Pd matrix have been studied for more than a dozen years. PdDx sample subjected to electrochemical/gas loading or deuterium desorption/deloading generate weak random fluxes of DD-reaction products (neutrons and protons) and energetic alpha particles. However, reproducibility of these emissions was low depending on material quality and experimental conditions. Here we present new reproducible results on DD-reaction products, energetic alpha particles and soft X-ray emissions detected in controlled conditions of exothermic deuterium desorption from the surface of Pd/PdO:D-x heterostructure.
