This paper presents CofiFab, a coarse-to-fine 3D fabrication solution, combining printing and 2D laser cutting for cost-effective of large objects at lower cost higher speed. Our key approach is to first build coarse internal base structures within the given object using cutting, then attach thin 3D-printed parts, as an external shell, onto recover fine surface details. CofiFab achieves this with three novel algorithmic components. First, we formulate optimization model compute fabricatable...
Two energetic compounds, 4,8-dinitraminodifurazano[3,4-b,e]pyrazine (1) and its potassium-based metal–organic framework (E-MOF) (2), were prepared, their crystal structures confirmed by single-crystal X-ray diffraction analysis. Compound 1 cocrystallizes with water molecules shows a three-dimensional (3D) sandwich-like supramolecular structure, which is rare in the known organic compounds. 2 has pillared layered structure pcu topology. The 3D featuring sql topology was constructed from...

Abstract Thermal runaway poses a critical safety concern for fuel cells, significantly impairing their performance and durability. Uneven current often leads to uneven temperature, exacerbating the risk of thermal runaway. The inadequate electrical conductivity gas diffusion layer (GDL) is identified as primary cause issues. To address this, multilayer composite (MC‐GDL) proposed designed enhance both conductivity. in‐plane MC‐GDL reaches an impressive 9.1 × 10 4 S m −1 . Under extreme...
The dense ceramic oxygen separation membrane holds promise to reduce the production cost significantly over current mature cryogenic distillation process. Preparation of membranes in hollow fiber geometry is expected lead a remarkable increase capacity unit. Gas-tight Ce0.8Sm0.2O2−δ−La0.8Sr0.2MnO3−δ dual-phase composite fibers were prepared by phase-inversion/sintering technique. A stable permeation rate 3.2 × 10−7 mol·cm−2·s−1 was measured under air/He gradient at 950 °C, and 3.0 found...
Abstract The fused nitrogen‐rich heterocycles, particularly planar structures, possess many advantages over conventional single‐ring energetic compounds. π‐π stacked structures result in enhanced safety. Meanwhile, their conjugated systems give rise to good properties. This review focused on the syntheses, properties, and potential applications of materials based coplanar heterocycles. Most these compounds exhibit excellent detonation characteristics along with low mechanical sensitivity...
An impact ignition experiment was conducted using a split Hopkinson pressure bar at 22, 65, 125, and 205 °C to study the behavior of an aluminum/polytetrafluoroethylene reactive material under extreme conditions such as high temperature, pressure, strain rate. The dynamic compression behavior, micromorphology, threshold, delay time, failure characteristics were investigated. results indicate that material's sensitivity continuously increases with temperature. Moreover, three cases times...

Acoustic black hole (ABH) has gained significant attention in the scientific community as a passive, effective, and lightweight solution for controlling noise induced by structural vibrations. This article introduces ABH technology into composite plate structure, resulting design of an plate. A finite element model free‐space acoustic field is developed to evaluate this structure's vibrational properties. Results indicate that coating damping layer (ABH + AC DL) demonstrates excellent...
The air-cooled fuel cell is a promising energy conversion device. However, the characteristics of forced convection often rapidly expel water from gas diffusion layer (GDL) into flow field, which reduces humidity membrane electrode assembly (MEA). Under low-humidity conditions, proton conductivity exchange (PEM) decreases, thereby impairing performance and durability cell. Inspired by tortuous transport pathways in maze model, we designed GDL with maze-like structure (M-GDL) to extend path,...
