High Cycle Fatigue Properties of PM‐HIPed High‐Nitrogen Tool Steel: Effect of Surface Condition

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 6, Page 2097-2115, June 2026.
ABSTRACT This study explores the impact of surface condition on high‐cycle fatigue performance of a high‐nitrogen martensitic tool steel manufactured through powder metallurgy and hot isostatic pressing. In near‐net manufacturing applications, acid‐leaching pickling treatment and/or machining is used as a post‐treatment to remove the powder container ...

NIR‐II Imaging‐Guided Photothermal Activation of a TRPV4‐Targeted Nanoplatform Delivering Cycloastragenol to Promote Microglia Reprogramming and α‐Synuclein Clearance in Parkinson's Disease

Advanced Science, Volume 13, Issue 26, 8 May 2026.
ABSTRACT Current therapies for Parkinson's disease (PD) fail to concurrently address α‐synuclein (α‐syn) aggregation and microglia‐mediated neuroinflammation. Herein, we engineer a near‐infrared‐II (NIR‐II) phototheranostic nanoplatform, CAG/FD1080@MM‐aTRPV4, for synergistic regulation of microglial function and real‐time monitoring of PD pathology. We

Fluorescence modulation of an aggregation-induced emission active ligand via rigidification in a coordination polymer and its application in singlet oxygen sensing

, 2019
A new Zn(II)-based coordination polymer (CP) having the formula [Zn(L)(2,2'-bpy)] (1) was synthesized using ZnCl2, 3,3'-(anthracene-9,10-diyl)diacrylic acid ligand (H2L), and 2,2'-bipyridine (2,2'-bpy) in DMF under solvothermal conditions.

Protein‐Template Gold Nanoclusters Induce Differentiation and Modify the Functional Properties of Primary Astrocytes

Advanced NanoBiomed Research, Volume 6, Issue 5, May 2026.
The incubation of primary astrocytes with fAuNCs‐BSA induces: (A) long‐term effects including fAuNCs‐BSA internalization, red cell fluorescence, differentiation, upregulation of Ca2+ signaling, Cl‐current, and cell volume regulation. B) Short‐term (200 ms) stimulation with UV LED light increases in Ca2+ signaling and inhibition of K+ current. Astrocyte

Development of electron source feedback for enhanced X‐ray beam stability at NSLS‐II

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 585-595, May 2026.
An electron‐source feedback method has been demonstrated at the NSLS‐II Hard X‐ray Nanoprobe, using X‐ray beam position data to drive electron beam corrections. The approach suppresses dominant vibration peaks and significantly improves X‐ray beam stability and ptychographic image quality.Future synchrotron light sources are being designed to deliver ...

Nanofibers with Bragg gratings from equidistant holes

, 2011
We study nanofibers with Bragg gratings from equidistant holes. We calculate analytically and numerically the reflection and transmission coefficients for a single grating and also for a cavity formed by two gratings.
