Spatiotemporal control over cell behavior within bioprinted constructs remains a key challenge in biofabrication. Volumetric bioprinting using multi‐wavelength light sources permits to activate light‐sensitive intracellular proteins as well as optogenetic gene and protein expression circuits in bioprinted cells, in addition to enabling fast printing of

Although bladed disks of turbomachinery are nominally designed to be cyclically symmetric (tuned system), the vibration characteristics of all blades on a disk are slightly different due to the manufacturing tolerance, the deviation of the material ...

3D shaping of Ni1‐xFexCo2O4 spinel electrocatalyst to form high aspect ratio nanorods, made of 25 nm grain size particles and directly grown on Nickel felt, is proposed to improve the performance of industrial catalysts based on group‐VIII transition‐metal oxides.

A Comparison between Two Reduction Strategies for Shrouded Bladed Disks
Shrouded bladed disks exhibit a nonlinear dynamic behavior due to the contact interfaces at shrouds between neighboring blades. As a result, reduced order models (ROMs) are mandatory to compute the response levels during the design phase for high cycle ...

The present paper is focused on the post processing of the data coming from the Blade Tip-Timing (BTT) sensors in the case where two very close peaks are present in the frequency response of the vibrating system.

Analysis of the Mode Shapes of Kaplan Runners
To prevent lifetime shortening and premature failure in turbine runners, it is of paramount importance to analyse and understand its dynamic response and determine the factors that affect it.

The objective was to better understand the vibratory response of bladed disk assemblies that occur in jet engines or turbopumps. Two basic problems were investigated: how friction affects flutter; and how friction, mistuning, and stage aerodynamics ...

A pixelated full‐color display is driven by a 1064 nm near‐infrared laser without electrical wiring. A graphite photothermal layer converts light into heat, while an aluminum heat‐spreading layer redistributes it for uniform color within each pixel. Optimizing pixel size and spacing suppresses thermal crosstalk, enabling non‐contact reproduction of ...
