Intermittent Flow Regimes in a Transonic Fan Airfoil Cascade
International Journal of Rotating Machinery, 2004 A study was conducted in the NASA Glenn Research Center (NASA-GRC) linear cascade on the intermittent flow on the suction surface of an airfoil section from the tip region of a modern low aspect ratio fan blade.

Advanced Functional Materials, EarlyView.A two‐step DNA metallization process is presented for the modular assembly of metal sulfide nanoparticles (NPs) on MoS2, with nanoscale control over their separation and ability to concomitantly assemble different kind of NPs. This allowed to tailor the photoinduced electrical response of phototransistors to different wavelengths, according to the ...

Advanced Functional Materials, EarlyView.This work addresses the challenge of current–voltage asymmetry in scalable laminated semitransparent organic photovoltaics (OPVs) for indoor applications. Vertical stratification of materials is shown to create an energy barrier, leading to performance differences under different illumination directions.

Accurate 2-D Modelling of Transonic Compressor Cascade Aerodynamics
Aerospace, 2019 Modern aeronautic fans are characterised by a transonic flow regime near the blade tip. Transonic cascades enable higher pressure ratios by a complex system of shockwaves arising across the blade passage, which has to be correctly reproduced in order to ...

Space shuttle: Verification of transition reentry corridor at high angles of attack and determination of transition aerodynamic characteristics and subsonic aerodynamic characteristics at low angles of attack for the Boeing H-32 booster [PDF]
Experimental aerodynamic investigations were made in a transonic wind tunnel on a 1/150-scale model of the Boeing H-32 space shuttle booster configuration. The purpose of the test was: (1) to verify the transonic reentry corridor at high angles of attack;

Advanced Functional Materials, EarlyView.This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.
