Summary: Replicable experimental results on low-energy nuclear fusion reactions demonstrate that helium (including He-3 and He-4 isotopes) can be synthesized through the interaction of deuterium nuclei with solids in the experimental system. The concentration of generated helium is found to increase with both the kinetic energy of the interacting deuterium nuclei and the temperature of the sample holder.

Summary: An in-flight beam of N-16 was produced via the single-neutron adding (d,p) reaction in inverse kinematics. The isomer fraction of N-16 at different reaction energies was determined, and the sensitivity to the angular acceptance of the recoils was observed.

Summary: Low-dimensional high-entropy alloy (HEA) nanomaterials have been widely used as electrocatalysts for energy conversion reactions due to their superior electron mobility, catalytically active sites, and optimal electronic structure. The high-entropy, lattice distortion, and sluggish diffusion effects further enhance their electrocatalytic performance. Understanding the structure-activity relationships of low-dimensional HEA catalysts is crucial for developing more efficient electrocatalysts.

Summary: We demonstrate the generation of a nuclear-excited low-temperature plasma source using a high surface-to-volume ratio porous electrode structure within an ionizing radiation field. The energy absorption efficiency and specific ion output current are significantly higher in the porous electrode system compared to the solid electrode system. This research has important implications for plasma science and ionizing radiation applications.

Summary: It is widely acknowledged that without energy storage and reliable additional energy generation, such as hydrogen energy storage and nuclear energy generation, it is impossible to completely eliminate the need for gas, oil, and coal combustion in order to keep prices low and avoid energy scarcity while transitioning to net zero.

Summary: Due to their unique nonlinear characteristics, bionic structures can effectively broaden the acquisition bandwidth and improve the performance of energy harvesters. Inspired by the flight motion of dipterans, a novel bionic quadstable piezoelectric energy harvester (BQPEH) is designed to collect low-frequency vibration. The combination of the click mechanism and snap-through motion in this bionic energy harvester broadens its application scenarios and improves adaptability.

Summary: The Th-229 nucleus has a low-energy isomeric state which has inspired the development of low-energy nuclear physics. Resonant laser excitation of the Th-229 isomer could be used to create a highly accurate optical clock, providing sensitivity to hypothetical new physics beyond the standard model. Although the challenge of laser excitation of Th-229 remains unsolved, recent experiments have advanced the field by providing essential information on transition energy and relevant nuclear properties.

Summary: The aim of this study was to investigate the compatibility of plants with different root systems in terms of nutrient procurement from limiting soil. Results showed that when two species with evolutionary origins in low fertility soils were grown together, there was an enhanced uptake of phosphorus and manganese. In contrast, a species that probably originated from a more fertile soil procured lesser amounts of six elements from the soil when grown together with grasses. Moreover, two grasses tolerant of less fertile soils obtained more nutrients when they grew together with proteas.

Summary: Low-energy electron beam accelerators are becoming increasingly important in the radiation processing industry. However, the currently used dosimeters cannot directly measure surface dose. This study proposes a polymer material as a dosimeter candidate, measuring dose-dependent fluorescence intensity using fluorescence microscopy. However, the stability and fluorescence properties of the material have not been fully optimized.
