Advanced Materials, EarlyView.A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...

Forces on Centrifugal Pump Impellers [PDF]
, 1985 Forces are exerted on a centrifugal pump impeller, due to the asymmetry of the flow caused by the volute of diffuser, and to the motion of the center of the impeller whenever the shaft whirls. Recent work in the measurement of these forces as a function

Fully Inkjet‐Printed Organic Electrochemical Transistors: A Path Toward All‐Organic Electronics
Advanced Materials Technologies, EarlyView.Fully printed organic electrochemical transistors eliminate the metal electrodes used in conventional printed organic electronics. This work demonstrates the state of the art in three applications using PBFDO and PEDOT:PSS materials: a single‐material strain sensor for real‐time detection of finger flexion, an ion sensor for monitoring aqueous NaCl ...

Advanced Robotics Research, EarlyView.This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Impeller-Induced Rotor-Dynamic Forces [PDF]
, 1989 The flow through and around the rotor of a turbomachine exerts a force on the rotor and, hence, rotor shaft and bearing system. In some circumstances this force may lead to excitation of shaft whirl in the direction of impeller rotation.

Multistability and memory effect in a highly turbulent flow: experimental evidence for a global bifurcation [PDF]
, 2004 We report an experimental evidence of a global bifurcation on a highly turbulent von Karman flow. The mean flow presents multiple solutions: the canonical symmetric solution becomes marginally unstable towards a flow which breaks the basic symmetry of ...
