Development of a Synthetic Hydrogel to Foster Microvascularization of an Endometriosis Microphysiological System

open access: yesAdvanced Healthcare Materials, EarlyView.
ABSTRACT The ascent of novel alternative methods in drug development spotlights the dual needs for improved biological fidelity to in vivo, along with reproducibility, especially in regulatory applications. The need for pre‐clinical models of patient‐derived endometriosis lesions motivates the development of a vascularizable, completely synthetic ...

Functional Blood‐Brain Barrier Crossing by Biomimetic M13 Phage Vectors for Targeted Neuronal Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This study investigates the M13 bacteriophage as a biomimetic nanovector capable of crossing in vitro models of the blood–brain barrier. By exploiting peculiar transcellular pathways, M13 avoids lysosomal degradation and preserves its structural integrity and functionality.

Control-Oriented Model of a Generating Set Comprising a Diesel Engine and a Synchronous Generator [PDF]

open access: yesModeling, Identification and Control, 2015
A generating set (Genset) comprises a prime mover such as a Diesel Engine, and a synchronous generator. The most important controllers of such systems are the speed governor to regulate the engine or shaft speed and the automatic voltage regulator (AVR ...

Lattice‐Matched 2D Template Enables Efficient Cesium Tin Halide Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Lattice‐matched 2D perovskite PEA2CsSn2I7 templates the out‐of‐plane growth of inorganic 3D γ‐CsSnI3 along the (110) plane, forming highly oriented 2D/3D tin halide perovskite heterostructures. With reduced trap states and mitigated δ‐phase impurities, the CsSnI3‐based solar cells achieve a power conversion efficiency of 15.27% and maintain stable ...

A novel stable nanopositioner based on a single piezoelectric stack: PistolDrive

open access: yesAIP Advances, 2018
We describe a novel stable piezoelectric nanopositioner which just use one piezoelectric stack and one simple driving signal, in which the central shaft is clamped by one BeCu spring and four SiN balls that bonded to the inner wall of the cylindrical ...
