Mind the gap: a new insight into the tip leakage vortex using stereo-PIV [PDF]

, 2019
The tip leakage vortex (TLV), which develops in the clearance between the rotor and the stator of axial hydro turbines, has been studied for decades. Yet, many associated phenomena are still not understood.

Study on the Suppression of Tip Leakage Vortex in Axial Flow Pumps Based on Circumferential Grooving in the Rotor Chamber

Journal of Marine Science and Engineering
The stability of axial flow pumps is significantly affected by the tip leakage vortex (TLV), which is generated through the entrainment of the main flow.

Targeting Peptostreptococcus anaerobius with an Iron‐Based Nanozyme Reverses Ferroptosis Resistance and Enhances Antitumor Immunity in Colorectal Cancer

Advanced Science, Volume 13, Issue 35, 24 June 2026.
An iron‐based nanozyme selectively eliminates intratumoral P. anaerobius while catalytically generating ROS to induce ferroptosis, synergistically suppressing colorectal cancer growth and activating anti‐tumor immunity through immunogenic cell death. ABSTRACT The intratumoral microbiota is a critical determinant of therapeutic outcomes in colorectal ...

Multi-scale leakage vortex interaction analysis in tip clearance of low-head pumped hydroelectric energy storage systems in pump mode [PDF]

In low-head pumped hydroelectric energy storage systems operating in pumping mode, the tip clearance leakage vortex, emerging from the narrow gap between the impeller's outer perimeter and the pump casing, significantly impacts unit efficiency, head, and

Tailored Porous Bimetallic Nanozyme Platform for Full‐Cycle Therapeutics of Intestinal Ischemia/Reperfusion

Advanced Science, Volume 13, Issue 34, 19 June 2026.
ABSTRACT Intestinal ischemia/reperfusion (I/R) injury presents a biphasic pathology: an acute oxidative‐inflammatory phase leading to organ failure, and a recovery phase marked by mucosal dysfunction and bacterial translocation. The developed MPB@TA‐Cu‐Ma nanocomposite functions as a dual‐phase therapeutic platform with significant efficacy. It rapidly

ALKBH3 m1A Demethylase Deficiency Reduces Alzheimer's Amyloid‐β Pathology

Advanced Science, Volume 13, Issue 32, 9 June 2026.
This study identifies that ALKBH3‐driven m1A demethylation orchestrates Alzheimer's disease progression by disrupting mitochondrial and synaptic homeostasis. This epitranscriptomic mechanism suppresses PINK1‐mediated mitophagy via m1A erasure, leading to mitochondrial dysfunction, oxidative stress, elevated Aβ production, and impaired microglial ...

Stable neuronal representations underlie cognitive resilience to Alzheimer's disease pathology

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION While Alzheimer's disease (AD) typically elicits progressive cognitive decline, some individuals with significant AD pathology maintain cognition. Understanding the neuronal underpinnings of such cognitive resilience would propel the development of interventions for delaying dementia.

Reynolds stress measurements in a turbine tip leakage vortex

, 2009
An experimental study of the structure of turbulence in a tip leakage vortex was conducted in a large scale, linear turbine cascade. The study was performed in a cross sectional plane 0.96 of the axial chord length downstream of the blade leading edge ...

Enzymatic Synthesis of NAD+

Current Protocols, Volume 6, Issue 6, June 2026.
Abstract Nicotinamide adenine dinucleotide (NAD+) is an essential metabolite involved in numerous biological processes, functioning both as a redox cofactor in cellular energy metabolism and as a co‐substrate for NAD+‐utilizing enzymes, including sirtuins and poly(ADP‐ribose) polymerases.
