Summary: The laser ignition has been proposed for safe and reliable ignition of explosives, but high energy has hindered its practical application. Developing a photosensitizer with good laser ignition performance under low energy is significant. A GO/RDX composite film showed improved laser photothermal properties, with the temperature rising significantly under laser irradiation due to the decomposition and combustion of RDX. The composite film could be a promising device for low initial energy photothermal ignition.

Summary: This study investigated the physiological response mechanism of alfalfa seedlings roots to the explosive RDX in order to enhance phytoremediation efficiency. The study analyzed the plant response to different levels of RDX from the perspectives of mineral nutrition and metabolic networks. The results showed that RDX exposure caused changes in root mineral metabolism and disrupted root basal metabolism, resulting in the accumulation of RDX in the roots and differential expression of metabolites. This study highlights the importance of mineral nutrition and metabolic networks in the physiological response of roots to RDX, and their role in improving phytoremediation efficiency.

Summary: This study experimentally investigates the mechanisms to control the blunt-end induced effective attractions between densely packed spherical dsDNA brushes. By analyzing the effects of parameters such as functionality, salinity, and dsDNA fragment length on the brush and dsDNA fragment conformation, it is found that a decrease in functionality or an increase in salt content leads to the reduction of effective attractions.

Summary: In this study, the near-field spray characteristics of electrohydrodynamic atomization (EHDA) for viscous liquids were investigated under various temperatures, electric Bond numbers, and dimensionless flow rates using high-speed imaging technique. The results showed that increasing temperature promoted the appearance of the stable cone-jet mode and improved the spray angle and droplet size distributions. An Arrhenius-type equation was introduced to predict the dimensionless droplet size under different flow rates and liquid temperatures.

Summary: Electrospraying, as a method of fluid atomization via high voltage application, produces more uniform droplets compared to other spraying modes. Previous studies primarily focused on the cone jet mode, which has limited applications due to the narrow range of applied voltage. In order to overcome this limitation, alternative spray modes need to be considered and thoroughly understood.

Summary: Research on nanocrystals synthesized in solution is driven by their unique physical properties determined by sizes and shapes. However, the limited understanding of crystallization, particularly the prevalence of noncrystalline intermediates, poses a challenge. In situ X-ray scattering reveals that the nucleation and growth of nanocrystals are constrained within amorphous intermediates, which play a crucial role in determining the final crystal characteristics and size.

Summary: This study performed a series of isothermal induction time studies and used machine learning techniques to analyze the correlations between vessel hydrodynamic features and nucleation kinetic parameters. The best performing models for nucleation rate were found to be a nonlinear random Forest model and a nonlinear gradient boosting model, while a nonlinear gradient boosting model outperformed other models for growth time. The ensemble of these models predicted the probability of nucleation solely from hydrodynamic features with an overall root mean square error of 0.16. This work demonstrates how machine learning approaches can provide insights into the scale-up of an unseeded crystallization process by analyzing limited datasets of induction times.

Summary: Self-standing carbon fiber electrodes show promise for solid-state battery technology due to their networked structures, robustness, and ability to confine Li dendrites. In this study, carbonized 3D electrospun fibers filled with polymer electrolytes were evaluated as anodes in solid-state lithium half cells. The research found that these fiber electrodes had high wettability with electrolytes, promoting intimate contact and delivering high initial capacities. However, the cells experienced gradual capacity fade in later cycles due to parasitic reactions and increased cell resistance. The benchmarking against similar cells with liquid electrolyte showed that Li storage in these fiber electrodes is intermediate between graphite and hard carbon in terms of lithiation voltage.

Summary: Reproducing the mechanical and biological performance of blood vessels is a challenge in tissue engineering, but additive-lathe printing with a vertical mandrel can fabricate uniform grafts. This study used gelatin methacryloyl (gelMA) hydrogel to print grafts in a helical pattern on a rotating mandrel. The printing parameters were optimized to improve bonding between filaments and eliminate sagging, resulting in grafts with similar anisotropic properties to native blood vessels. The printing system showed no leakage during burst pressure measurement, indicating its potential for vascular grafts in cardiovascular disease treatment.

Summary: Global warming is a pressing environmental issue, mainly caused by carbon dioxide (CO2). Various technologies, such as adsorption, cryogenic separation, and sequestration, have been developed for CO2 separation and storage/utilization. Among these, carbon capture using nano-adsorbents shows promise due to their excellent CO2 separation and storage performance. In this study, a facile synthesis method was developed for selective CO2 separation and storage using ZIF-8 hollow nanospheres. The optimized hollow ZIF-8 nanospheres exhibited remarkable CO2 adsorption capability, good CO2 storage capacity, and excellent cyclic adsorption/desorption performance. These findings are important for the development of nanomaterials for future CO2 capture technologies.

Summary: Several additives and solvents can switch the polymorphic outcome of solvent-mediated phase transformation experiments and crystallization of nitrofurantoin. The selection of alcohols or the use of crystallization additives leads to the formation of polymorph α, while most solvents result in polymorph β. This can be attributed to the reversed apparent relative solubility of nitrofurantoin polymorphs in different solvents or in the presence of additives.
