Shock wave propagation characteristics of aluminum‐containing explosive in corrugated steel‐lined tunnel

open access: yesDeep Underground Science and Engineering, EarlyView.
Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

Structure‐Driven Thermal Insulation Through Single‐ and Double‐Shell Hollow Silica Nanospheres Via a Single‐Step Sacrificial‐Interlayer Strategy

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A single‐step sacrificial‐interlayer strategy enables precise modulation of inter‐shell spacing in hollow silica nanospheres, allowing direct comparison of thermal insulation characteristics between single‐ and double‐shell architectures. The hierarchical design amplifies phonon scattering and disrupts solid heat pathways, achieving an ultralow thermal

The Critical Role of Economies of Scale: A Techno‐Economic Assessment of Small‐ Versus Large‐Scale Biogas Upgrading in Rural Tanzania

open access: yesEnergy Science &Engineering, EarlyView.
Small‐scale biogas upgrading can improve methane quality but remains financially unattractive to individual rural households. Community‐scale implementation substantially lowers energy costs, demonstrating that economies of scale are critical to making purified biogas a viable clean‐cooking option in Tanzania.

Numerical study of the steel plate shear walls with different corrugation shapes inside the sandwich panels under the seismic loading condition [PDF]

open access: yesAIP Advances
Steel plate shear walls are widely employed as lateral force-resisting systems in low- to high-rise buildings. While the infill plate critically influences cyclic performance, conventional flat plates exhibit limited energy dissipation and susceptibility

Hybrid modes of the passive-core corrugated-waveguide laser

open access: yes, 1976
Coupled-mode theory is employed to obtain the threshold gains for oscillation on hybrid modes of a passive-core corrugated-waveguide laser pumped in a central portion of its length.

Electrochemical Valence‐Regulated Biomimetic Nanozymes for Breast Cancer Metabolism Inhibition and Potentiated Catalytic Immunotherapy

open access: yesExploration, EarlyView.
MnOx nanozymes face low tumoricidal activity and PD‐L1‐mediated immune attenuation. Electrochemically regulated M‐MnOx with high oxidase activity was TCM‐wrapped into TMO. TMO targets tumors, triggers ICD, activates cGAS‐STING, antagonizes PD‐L1, and suppresses tumor recurrence, providing new insights for Mn‐based nanomaterials.

Bending Optimization of Composite Sandwich Panels with Second-Order Corrugated Cores

open access: yesInternational Journal of Advanced Design and Manufacturing Technology
Second-order corrugated cores are one type of hierarchical cores that use the common corrugated cores as constituent elements for the main core. This paper attempts to identify and optimize the bending properties of composite sandwich panels with second ...
