Abstract Accelerating the discovery of advanced materials is crucial for modern industries, aerospace, biomedicine, and energy. Nevertheless, only a small fraction are currently under experimental investigation within vast chemical space. Materials scientists plagued by time-consuming labor-intensive experiments due to lacking efficient material strategies. Artificial intelligence (AI) has emerged as promising instrument bridge this gap. Although numerous AI toolkits or platforms science have been developed, they suffer from many shortcomings. These include primarily focusing on property prediction being unfriendly programming experience, especially performing poorly with limited data. Here, we developed MLMD, an platform design. It capable effectively discovering novel high-potential properties end-to-end, utilizing model inference, surrogate optimization, even working in situations data scarcity based active learning. Additionally, it integrates analysis, descriptor refactoring, hyper-parameters auto-optimizing, prediction. also provides web-based friendly interface without need can be used anywhere, anytime. MLMD dedicated integration experiment/computation design, accelerate new desired one multiple properties. demonstrates strong power direct various (perovskites, steel, high-entropy alloy, etc). will essential tool facilitate advancement informatics.

The construction and modification of novel energetic frameworks to achieve an ideal balance between high energy density good stability are a continuous pursuit for researchers. In this work, fused [5,6,5]-tricyclic framework was utilized as the host encapsulate oxidant molecules first time. A series new pyridazine-based [5,6] [5,6,5] polycyclic nitrogen-rich skeletons their derivatives were designed synthesized. Two strategies, amino oxidation host-guest inclusion, used modify skeleton in only one step. All compounds exhibit comprehensive properties (

Nitro groups have been demonstrated to play a decisive role in the development of most powerful known energetic materials. Two trinitromethyl-substituted 1H-1,2,4-triazole bridging nitropyrazoles were first synthesized by straightforward routes and characterized chemical (MS, NMR, IR spectroscopy, single-crystal X-ray diffraction) experimental analysis (sensitivity toward friction, impact, differential scanning calorimetry-thermogravimetric test). Their detonation properties (detonation pressure, velocity, etc.) predicted EXPLO5 package based on crystal density calculated heat formation with Gaussian 09. These new trinitromethyl triazoles found show suitable sensitivities, high density, highly positive formation. The combination exceedingly performances superior those HMX (1,3,5,7-tetranitrotetraazacyclooctane), its preparation highlights compound 8 as promising high-energy material (HEDM). This work supports effectivity utterly manipulable nitration provides generalizable design synthesis strategy for developing HEDMs.
