Topological Quantum Biomaterials Enable Pyroptosis‐Senescence Coupling for Enhanced Colorectal Cancer Therapy

Advanced Science, EarlyView.
This work reports conceptually unprecedented topological quantum biomaterials derived from engineered Pd3Sn nanostrips for oncological applications. Their near‐Fermi‐level electronic architecture and superior interfacial charge transport facilitate ultrasound‐amplified redox reactions and efficient ROS generation.

Nonequilibrium spin dynamics in the chiral soliton lattice host YbNi3Al9

Results in Physics
The uniaxial chiral magnetic material YbNi3Al9 is proposed as a host for a chiral soliton lattice (CSL). In this study, we thoroughly investigate the spin dynamics in YbNi3Al9 single crystals using magnetization (M)-relaxation and electron spin resonance

Origin of electron spin resonance in La0.7Ca0.3MnO3

, 2003
An electron spin resonance study was carried out for a La0.7Ca0.3MnO3 bulk sample above the ferromagnetic ordering temperature. From careful analysis on the ESR parameters, it is shown that itinerant spins interacting with magnetic spin clusters in ...

Atomically Dispersed Fe‐Modified SnS for Sn‐Centered Peroxymonosulfate Activation Toward Acetaminophen Degradation

Advanced Science, EarlyView.
Atomically dispersed Fe regulates the local electronic environment and surface properties of SnS, while PMS preferentially coordinates to Sn through Sn–O interaction. Fe incorporation further enhances the Sn–OPMS interfacial interaction, facilitating Sn‐centered PMS activation and the generation of SO4•−/•OH for APAP degradation, thereby clarifying the

Susceptibility Magnetic and High Magnetic Field ESR Measurement of SrCu2(PO4)2

Makara Seri Sains, 2007
The magnetic susceptibility and high magnetic ESR measurement of SrCu2(PO4)2 has been performed at temperatures ranging from 4.2 K to 300 K and 4.2 K to 77 K, respectively. The magnetic susceptibility shows a broad maximum around T = 40 K.

A Neutrophil Membrane‐Encapsulated Pd/hCeO2 Nanoformulation for Alleviating Age‐Dependent Perioperative Neurocognitive Disorders

Advanced Science, EarlyView.
This study reports a neutrophil membrane‐encapsulated Pd/hCeO2 nanozyme (PCN) for targeted treatment of perioperative neurocognitive disorders (PND) in aged mice. PCN inhibits glycolysis‐driven microglial activation and neuroinflammation, improves mitochondrial respiration, and maintains blood‐brain barrier integrity and synaptic function, ultimately ...

Electron Spin resonance (ESR) dating of some European Late Lower Pleistocene sites [PDF]

, 2007
InWestern Europe, most of the oldest prehistoric sites (ranging from 2 Ma to 500 ka) are associated with clastic or carbonated karstic environments. Here, the electron spin resonance (ESR) dating method is often the only one method permitting to place ...

Isotropic Spin Trap EPR Spectra Simulation by Fast Fourier Transform (FFT)

E-Journal of Chemistry, 2005
The detection and investigation of free radicals forming in living systems became possible due to the introduction of the method of spin traps. In this work, the electron spin resonance (ESR) spectra of DMPO/HO.

Identification of γ-Irradiated Spices by Electron Spin Resonance (ESR) Spectrometry

Food Hygiene and Safety Science (Shokuhin Eiseigaku Zasshi), 1990
The electron spin resonance (ESR) spectrometry spectra of white (WP), black (BP) and red (Capsicum annuum L. var. frutescerns L., RP) peppers each had a principal signal with a g-value of 2.0043, and the intensities of the principal signals were increased not only by γ-irradiation but also by heating.
