Study of the Propeller with Small Blades on the Blade Tips
Journal of the Society of Naval Architects of Japan, 1987 The author performed cavitation test (cavitation observation, propeller open test, fluctuating pressure measurement and noise measurement) in uniform flow to compare the characteristics between the conventional (original) and the propeller with small blade on the blade tips (bladelet propeller).From these test, it was suggested that the reduction was ...

3D Concrete Printing of Triply Periodic Minimum Surfaces for Enhanced Carbon Capture and Storage
Advanced Functional Materials, EarlyView.A 3D‐printable and carbon‐capturing concrete is developed by replacing cement with diatomaceous earth (DE), which enhances rheology, provides hierarchical porosity, and serves as a nucleation site for carbonation. Maximum absorption of 488.7 gCO2 kgcement−1 is achieved in 7 days, a 142% increase over conventional concrete, and the triply periodic ...

Thermal Expansion Behavior of PM6 Studied Using In Situ Wide‐Angle X‐Ray Scattering
Advanced Functional Materials, EarlyView.In organic photovoltaics, small morphological changes can significantly impact performance. This study examines the thermal expansion of PM6 using in situ WAXS and GIWAXS from 30 to 300 °C. By analyzing samples of increasing complexity, factors like initial anisotropic nanoscale arrangements and substrate mismatches are quantified, revealing systematic
