The study of the Fleischmann–Pons Effect (FPE), i.e. the production of excess power production during electrochemical loading of deuterium in palladium (in the past labeled cold fusion) has had a notably multidisciplinary character, involving solid state and nuclear physics, material science, electrochemistry and other fields. Correlations between the material status and the occurrence of the effect as well as some changes in the electrochemical interface status have been observed. Although during the last two decades, in several calorimetric experiments the effect was observed to be well above the measurement uncertainty, the mechanism producing the excess power is not completely understood. So far, the lack of reproducibility has been responsible for the absence of a clear explanation of the phenomenon based on experimental apparatus designed to enhance the spectrum of information required to define the effect. Recently, In order to improve this aspect of this research, specific work has been carried out to investigate whether the excess power was produced concurrently with the emission of Radio Frequency from the active cathode. Suitable probes and triggering included in the RF experimental system revealed RF signal emission during electrochemical loading of palladium samples, and a correlation between the heat production, in active samples, and RF signal emission was found. The preliminary results highlight the importance of performing studies on the electrodynamic effects that may be involved in the phenomenon, and the importance of the design of appropriate instruments designed to investigate unexplored regions of metal hydrogen systems.
Nuclear Transmutations and Stabilization of Unstable Nuclei in the Cold Fusion Phenomenon∗
Authors: Kozima Hideo 
Published: December 2024

We summarize the nuclear transmutations observed in the cold fusion phenomenon (CFP) putting a weight on the biotransmutation, i.e. nuclear transmutations in biological systems. The CF materials, i.e. materials where occurs the CFP, are classified into three groups: (1) the metallic material includes transition-metal hydrides (e.g. NiHx, AuHx) and deuterides (e.g. PdDx, TiDx), (2) the carbonic material includes hydrogen graphite (HCx) and cross-linked polyethylene (XLPE) and (3) the biological material includes microorganisms, microbial cultures and biological tissues or organs. We explain these characteristics briefly in this paper. The stabilization of unstable nuclei, including the decay-time shortening of radioactive nuclei, in the nuclear transmutation is especially interesting from the applicatory point of view in relation to the treatment of the hazardous nuclear waste accompanied to the nuclear power plant. A characteristic of biological systems where occurs selective adsorption of specific ions seems especially useful for the application. If we have a microorganism or microbial culture absorbing an ion of a radioactive element selectively, we can remediate the radioactivity by the biotransmutation.
Dr. Mahadeva Srinivasan: Research Pioneer in the LENR Field
Authors: Grimshaw Thomas W. 
Published: December 2024

Dr. Mahadeva Srinivasan was one of the earliest and most productive researchers in the LENR field. He took an immediate interest in the phenomenon and began research within a day or two after the March 23, 1989 announcement – at a time when he already had more than 30 years of nuclear research experience at India’s Bhabba Atomic Research Center (BARC). He conducted many LENR investigations using several methods, with emphasis on neutron emission and tritium generation as signatures of the effect. After he retired from BARC in 1997, he became very active in the field after a 10-year “silent period”. His main emphasis after 2008 was on promoting LENR research in India. Because of his stature in the nuclear field in India, Dr. Srinivasan was able through his connections and friendships to arrange for LENR research programs and funding at several organizations. He chaired the 16th International Conference on Cold Fusion (ICCF-16) in Chennai in 2011.
Lattice Energy Converter

Published: December 2024

Multiple implementations of a Lattice Energy Converter (LEC) have demonstrated the ability to self-initiate and self-sustain the production of a voltage and current over extended periods of time. A LEC converts the internal energy within the lattice of some materials, such as palladium, or of gases occluded within the lattice, such as hydrogen or deuterium, into ionizing radiation and elec- trical energy. Experiments include tests where the current-voltage (I-V) characteristics of the LEC were measured when an external voltage/current was applied, as well as other I-V tests where the spontaneous LEC voltage was measured as a function of tempera- ture and resistance. LEC voltage and current has been shown to increase with increased temperature. The electrical power produced by a LEC is similar to that produced by a nuclear battery however, a LEC does not require radioactive materials. While the energy levels produced to date are several orders of magnitude below those required for most power sources, the calculated flux of ionizing radiation necessary to produce the experimentally measured voltage and current would require the equivalent of several curies of ra- diation. These results have been independently replicated by two individuals. A video of the Lattice Energy Converter presentation, from the 2021 LENR workshop in honor of Dr. Srinivasan, is available at: https://www.youtube.com/watch?v=J4dzTWY_aWM This paper expands on the YouTube video presentation with additional analysis that supports the observed experimental results

Background
Stroke leads to various impairments like motor deficits, impaired trunk control and restricted mobility. However, rehabilitation professionals often underestimate the fundamental function of turning, which is essential for daily living activities like walking, cooking, or performing household chores. Impaired turning can be attributed to motor deficits post-stroke, resulting in restricted mobility and impaired trunk movement. Therefore, the present study aimed to determine the relationship between turn performance, trunk control, and mobility in stroke patients.

Materials and Methods
A total of 63 first-time supratentorial stroke (i.e., anterior circulation stroke) patients aged 18–90 years were recruited for the study. Turn performance was assessed by asking patients to walk for 10 feet comfortably, then take a 180° turn and return to the starting position. In addition, the duration and number of steps were recorded. Following this, the Trunk Impairment Scale (TIS) and Stroke Rehabilitation Assessment of Movement (STREAM) were used to assess trunk impairment and mobility, respectively. The group turn performance was analyzed using the Kruskal–Wallis test with a post hoc Mann–Whitney U test for between-group comparisons. The turn duration and turn steps were correlated with age, trunk control, and mobility using Spearman’s rank correlation. A regression analysis was performed to determine the association of turn performance with age, trunk control, and mobility among stroke patients.

Results
Thirty stroke patients had turning difficulty, and 33 did not. Hence, they were categorized into the turning difficulty (TD) and non-turning difficulty (NTD) groups. When correlated with turn duration and the number of steps taken by the stroke patients while turning, the STREAM and TIS scores revealed a significant negative correlation (p < 0.001). The subjects’ age showed a significant positive correlation with the turn duration and number of steps taken by stroke patients while turning (p < 0.001). A significant association was also found between turn performance and age and trunk control. However, there was no significant association between turn performance and mobility.

Conclusion
The observed associations highlight the complexity of turning ability and trunk control necessary to complete a turn safely. Additionally, with advancing age, turn performance and turning movement are compromised in stroke patients. This indicates that turning difficulty is more pronounced in older individuals with stroke.

Published: December 2024

This study aimed to document knowledge on the use of IFAs and iron-rich diet among pregnant women in Iringa Municipality. The study used both primary and secondary data. Primary data were collected from 100 respondents using researcher administered questionnaires and 4 key informants by using interview method. The sample size were selected by using purposive and convenience sampling technique. Qualitative data were analysed by using content analysis technique where data were organized and summarized into different themes and ideas which were express by key respondents. The findings indicated that 87% of respondents were aware of IFAs and 85% were aware of the sources of iron-rich diet to both maternal and foetal health, 62% became aware during their three months of pregnancies and 55% got information about IFAs from their healthcare’s when visit clinics. The study concluded that most of the respondents were aware of IFAs and iron-rich diet through health workers when visit clinics during three months of pregnancies which is not proper since the supplements should be taken after one month of conceiving in order to prevent a mother from being anaemic and neural tube defects to unborn babies. Therefore, the study recommends that it is essential to implement comprehensive educational campaigns that utilize various media platforms: social media, community workshops, and radio broadcasts, to reach a wider audience.

Finger millet (Eleusine coracana L. Gaertn.), an ancient crop cultivated in India since 2300 BC, is highly valued in traditional production systems for its role in alleviating malnutrition, with a rich nutritional profile comprising 9.2% protein, 1.29% fat, 76.32% carbohydrates, and the highest calcium (344 mg%) and potassium (408 mg%) content among all cereals and millets. The present experiment entitled on “A Comparative Evaluation of Various Biostimulants on Finger Millet (Eleusine coracana L. Gaertn.) Growth and Yield in the Red Lateritic Region of West Bengal” was conducted during kharif season of 2022 at Farmers’ field, Chandrakona, Paschim Medinipur, West Bengal. The experiment was laid out in Randomized Block Design replicated thrice consisting of 6 treatments [T1: RDF (Recommended Dose of Fertlizes) + Seaweed Extracts at 0.2%, T2: RDF + Moringa Extracts at 2%, T3: RDF + Protein Hydrolysates & Amino acids at 0.2%) T4: RDF + Fulvic acid substances at 0.2%, T5: RDF + Panchagavya at 3%, T6: RDF (N: P: K- 30:15:15 kg ha-1)]. The objective of this study is to find out the effect of foliar nutrition on growth and yield attribute of Finger millets. The grain and straw yield of finger millet as influenced by different treatments are found to be significant. Foliar spray of nutrition has resulted variable yield differences among the treatments. The highest grain yield 26.19 q.ha-1 and straw yield 34.70 q.ha-1 were recorded by RDF + Protein Hydrolysates & Amino acids at 0.2% followed by T1 with the values of 25.12 q.ha-1 and 31.56 q.ha-1 respectively. From the above investigation it was evident that the foliar application of various biostimulants on finger millets had a positive impact on growth and yield, especially in nutrient-stressed soils. In this context, the present study aims to assess the feasibility and performance of finger millet cultivation with minimal nutrient input and the application of biostimulants in various combinations.
Modeling Diffusion in Functional Materials: From Density Functional Theory to Artificial Intelligence
Authors: Elbaz Yuval , Furman David , Caspary Toroker Maytal 
Published: July 2019

AbstractDiffusion describes the stochastic motion of particles and is often a key factor in determining the functionality of materials. Modeling diffusion of atoms can be very challenging for heterogeneous systems with high energy barriers. In this report, popular computational methodologies are covered to study diffusion mechanisms that are widely used in the community and both their strengths and weaknesses are presented. In static approaches, such as electronic structure theory, diffusion mechanisms are usually analyzed within the nudged elastic band (NEB) framework on the ground electronic surface usually obtained from a density functional theory (DFT) calculation. Another common approach to study diffusion mechanisms is based on molecular dynamics (MD) where the equations of motion are solved for every time step for all the atoms in the system. Unfortunately, both the static and dynamic approaches have inherent limitations that restrict the classes of diffusive systems that can be efficiently treated. Such limitations could be remedied by exploiting recent advances in artificial intelligence and machine learning techniques. Here, the most promising approaches in this emerging field for modeling diffusion are reported. It is believed that these knowledge‐intensive methods have a bright future ahead for the study of diffusion mechanisms in advanced functional materials.

AbstractAlthough the negative consequences of the global phenomenon of jellyfish (JF) swarms are well recognized, the use of their biomass for practical applications is mostly limited to a niche in the Asian food industry. This fact is quite surprising since JF's biomass comprises useful biomaterials such as Q‐mucin glycoprotein and collagen. In this work, the JF biomass, collected from two different species, is used to prepare electrospun scaffolds composed of nanometric “core–shell”‐type fibers, in which adjustment of the electrospinning process parameters can easily control their mechanical, morphological, and chemical properties. This nonwoven scaffold shows excellent biocompatibility and biodegradability, indicating suitability for biomedical research contexts. Performed cell proliferation assays show that the scaffold could support the growth of cardiac cells, fitting the requirement of tissue engineering. Additional incorporation of in situ‐generated silver nanoparticles in these nanofibers produced mats with potent antibacterial properties. Preclinical trials with the resulted mats on porcine wound healing models exhibit fast and complete healing of wounds.
The Analysis of Impedance Spectra for Core–Shell Microstructures: Why a Multiformalism Approach is Essential
Authors: Heath James P. , Harding John H. , Sinclair Derek C. , Dean Julian S. 
Published: July 2019

AbstractThe impedance response of a core–shell microstructure with 80% core volume fraction has been simulated using finite‐element modeling and compared to two equivalent circuits for a wide range of shell permittivity and conductivity values. Different equivalent circuits, corresponding to different variants of the well‐known brick layer model, are applicable for different combinations of material properties in the microstructure. When the shell has a similar conductivity or permittivity to the core, adding a parallel pathway increases the accuracy of the fit by ≈±10%. When both the conductivity and permittivity values of the core and shell regions are different the series circuit is a better fit. This is confirmed by multiformalism impedance analysis, which reveals features in the data that are not apparent using a single formalism. Finally, the conductivity and permittivity values for both the shell and core are extracted from the simulated spectra using all formalisms and compared to the original input values. The accuracy of the extracted values often depends on the impedance formalism used. It is concluded that impedance spectroscopy data must be analyzed using multiple formalisms when considering core–shell microstructures.

Published: July 2019

AbstractParticulate matter (PM) pollution has posed a huge health and economic burden worldwide. Most existing air filters used to remove PMs are structurally monotonous, cumbersome, and inevitably suffer from the compromise between removal efficiency and air permeability; developing an advanced air filter that can overcome these limitations is of significance but highly challenging. Herein, a novel strategy to create ultrathin, high‐performance air filters based on fluffy dual‐network structured polyacrylonitrile nanofiber/nets, via a humidity‐induced electrospinning/netting technique, is reported. By tailoring the ejection and phase separation of the charged liquids, this approach causes 2D ultrafine (≈20 nm) nanonets tightly bonded with fluffy pseudo‐3D nanofiber scaffolds to form dual‐network structures, with controllable pore size and stacking density on a large scale. The resultant nanofiber/net filters possess the integrated features of small pore size (<300 nm), high porosity (93.9%), low packing density, combined with desirable surface chemistry (4.3‐D dipole moment), resulting in high‐efficiency PM0.3 removal (>99.99%), low air resistance (only <0.11% of atmosphere pressure), and promising long‐term PM2.5 purification. The synthesis of such materials may provide new insights into the design and development of high‐performance filtration and separation materials for various applications.
