Performance of an optimized rotor blade at off-design flight conditions [PDF]
An investigation is made of the dynamic and aerodynamic performance of a helicopter rotor previously optimized for minimum 4/rev vertical shear and blade weight subject to certain dynamic and structural constraints.

How to boost the IDS output of an OECT? Anisotropic polymer alignment along the channel direction enables a 13‐fold increase in IDS. Such channel engineering opens the door to unprecedented signal amplification (here gmL/Wd = 2 580 S cm−1 with a PBTTT‐backbone bearing single‐ether side chains), faster ON/OFF switching, and improved stability for the ...

Coupled aerodynamic and acoustical predictions for turboprops [PDF]
To predict the noise fields for proposed turboprop airplanes, an existing turboprop noise code by Farassat has been modified to accept blade pressure inputs from a three-dimensional aerodynamic code.

Intrinsically‐stretchable, heavy‐metal‐free quantum dot color conversion layers are produced via a versatile crosslinking strategy. The color conversion layers exhibit minimal backlight leakage under mechanical strain, support high‐resolution patterning, and integrate seamlessly with micro‐light‐emitting diodes. Their incorporation in haptic‐responsive

This study presents a polyanhydride‐based delivery platform for single‐injection, self‐boosting vaccines. The system enables programmable, pulsatile release of diphtheria toxoid with high antigen recovery and is guided by machine learning for tunability. In vivo results show immune responses comparable to multi‐dose regimens, highlighting its potential
