Summary: The development of methods for controlling explosive chemical reactions is essential for the safe and efficient use of energetic materials. This study demonstrates the use of zinc oxide nanopowders doped with copper and iron as photosensitive materials to initiate explosions in the industrial explosive PETN. The addition of these nanopowders significantly reduces the energy required for initiation, enabling reliable explosion triggering using lasers of different wavelengths.

Summary: This study addresses the challenge of scalable pressureless sintering of nanocrystalline alumina ceramics using ultrafine alpha-Al2O3 nanopowders and a two-step sintering technique. The results show that the exceptional sinterability of these nanopowders can be attributed to their small size, large surface area, and good dispersity, rather than a new sintering mechanism. The importance of fast firing and non-equilibrium nature for low-temperature sintering of such nanopowders is highlighted.

Summary: In this study, ZnO and TiO2 nanopowders were prepared by pulsed laser reactive ablation of metallic targets. The structural, optical, and luminescent properties were investigated using various spectroscopic techniques. The results showed that the luminescent properties of the nanopowders could be modified by pulsed laser annealing, which changed their intrinsic defective structure. The optimal excitation wavelengths for luminescence were also determined.

Summary: The study combines continuous plasma and pulsed plasma to form thin films, using high densities of microwave discharge and a wide range of ion energies in pulsed laser ablation plasmas. This method reduces the need for dangerous and corrosive substances, as the required element can be obtained from pure solid targets. Additionally, the presence of contaminants, such as oxygen, is significantly reduced by conducting the laser ablation process in plasma as the background gas instead of a neutral gas.

Summary: The impact sensitivity to external stimuli is crucial for evaluating and designing high-performance energetic materials. Investigating the factors influencing sensitivity and uncovering the sensitivity mechanism remains a significant challenge. In this study, a physical model is established to assess the impact sensitivity of 16 energetic compounds based on the energy transfer of carriers using first-principles calculation. The results demonstrate a remarkable correlation between the empirical parameter ,/r, obtained by considering the band gap, density of states, and ability of electronic migration, and the experimental drop energy E50. This supports the basic assumption that the sensitivity of energetic materials decreases when electron transfer energies quickly dissipate to other molecules, making it difficult to form a hot spot.

Summary: A novel strategy to design and construct energetic covalent organic frameworks (COFs) is proposed in this study. ECOF-1, a two-dimensional crystalline COF assembled from triaminoguanidine salt, has been successfully prepared. ECOF-1 exhibits superior thermal stability, insensitivity, and inhibits the corrosiveness of NTO. Energetic COFs are promising as a functional platform to design high-energy and insensitive energetic materials.

Summary: The presence of a native oxide layer limits the performance of Al as a nanoenergetic material, but this issue can be resolved by coating the Al surface with a fluorocarbon nanofilm. This technique effectively turns the oxide layer into an energetic component and significantly enhances heat release during oxidation.

Summary: This study utilized femtosecond and picosecond lasers to create superhydrophilic surfaces and investigated their morphologies and surface chemistry. Due to significant variations in micro-nano structure and molecular compositions, surfaces fabricated by the two lasers showed notable differences in surface wettability. Furthermore, applying an eco-friendly coating on ultrafast laser fabricated surfaces can maintain superhydrophilic properties for over 14 months.
