Detection of Rotor Forced Response Vibrations Using Stationary Pressure Transducers in a Multistage Axial Compressor

International Journal of Rotating Machinery, 2015
Blade row interactions in turbomachinery can lead to blade vibrations and even high cycle fatigue. Forced response conditions occur when a forcing function (such as impingement of stator wakes) occurs at a frequency that matches the natural frequency of ...

Fish Scales: A Multifunctional Biomaterial from Nature

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Design optimization of a multi-stage axial compressor using through flow and a database of optimal airflows

Journal of the Global Power and Propulsion Society, 2018
The basic tool set to design multi-stage axial compressors consists of fast codes for throughflow and blade-to-blade analysis. Detailed blade row design is conducted with 3D CFD, mainly to control the end wall flow.

Cancer heterogeneity explored through immune cell deconvolution of the tumor microenvironment

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract Cancer is a highly heterogeneous disease, characterized by significant variability across multiple dimensions. This diversity has been extensively studied from various perspectives. In this study, we aim to examine cancer heterogeneity through the lens of immune cell composition within the tumor microenvironment.

Dynamic Characteristics Analysis of a Large Wind Turbine Gearbox Supported by Journal Bearings Under Different Lubrication States

Wind Energy, Volume 29, Issue 9, September 2026.
ABSTRACT Due to their superior load density, planetary gear journal bearings (PGJB) are progressively replacing rolling element bearings in wind turbine gearboxes; therefore, accurately revealing the dynamic characteristics of drivetrains supported by these bearings under variable operating conditions is crucial for ensuring operational reliability ...

Recent Developments in Electrochemical Lignin Depolymerization Using Flow Systems: A Mini Review

ChemElectroChem, Volume 13, Issue 16, 18 August 2026.
This review summarizes the current state of the electrochemical depolymerization of lignin focusing on studies performed in flow cells. Three anodic strategies are distinguished: oxygen evolution reaction substitution for energy‐efficient hydrogen generation, nonselective oligomer production, and selective aromatic monomer synthesis, such as vanillin ...
