Experimental and Numerical Study of Transonic Cooled Turbine Blades

International Journal of Turbomachinery, Propulsion and Power, 2018
State-of-the-art gas turbines (GT) operate at high temperatures that exceed the endurance limit of the material, and therefore the turbine components are cooled by the air taken from the compressor.

Low Percent Copper Doping Limits Bacterial Adhesion on Fluorapatite‐Based Bone Scaffolds

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 5, May 2026.
ABSTRACT Natural and engineered bone grafts are widely used in orthopedic and dental reconstruction; however, infection remains a persistent clinical challenge. Fluorapatite (FAp) is a chemically stable and osteoconductive bone substitute, but it lacks inherent antimicrobial properties. Copper (Cu), known for its potent antibacterial activity, could be

Numerical Investigation of Transonic Axial Compressor Rotor With Leading‐Edge Tubercles

Engineering Reports, Volume 8, Issue 3, March 2026.
Amplitude, wavelength, and span‐wise location of the leading‐edge tubercles on a transonic NASA Rotor 37 compressor are numerically optimized. An increase in efficiency by 0.52% compared to the corresponding baseline rotor is observed. The location of the shockwave moves downstream of the rotor with 1.91% higher pressure.

Summertime methane and carbon dioxide emission rates and associated variables from a national‐scale survey of 146 reservoirs in the United States

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Reservoirs are globally important sources of greenhouse gases, but the magnitude of their emissions is highly uncertain. Here, we present data for 146 reservoirs from two surveys of reservoir methane and carbon dioxide emissions, one at the regional scale in the midwestern United States and one at the national scale in the United States, plus ...
