Investigation of Radiation Effects on Coffee Beans Using ESR Technique

Cumhuriyet Science Journal, 2018
Inthis study, radiation effects on coffee beans have been investigated by Electron Spin Resonance (ESR) technique. ESR spectra of natural and irradiated samples at differentdoses between 0.5 Gy and 11 kGy by 60Co gamma source were recordedwith X-band ESR

Dual‐Targeted Biomimetic MoSe2 Nanozymes for Enhancing Peri‐Implant Soft Tissue Integration

Advanced Science, EarlyView.
A dual‐targeting biomimetic nanozyme, MoSe2@SPMM, selectively targets Staphylococcus aureus and oxidatively stressed macrophages. Near‐infrared activation couples contact‐enhanced photothermal bacterial eradication with reactive oxygen species scavenging to disrupt the pathogenic–immunological amplification loop.

Effect of phonons on the electron spin resonance absorption spectrum

New Journal of Physics, 2020
The unavoidable presence of vibrations in solid-state devices can drastically modify the expected electron spin resonance (ESR) absorption spectrum in magnetically active systems. In this work, we model the effect of phonons and temperature on the ESR

Magneto‐Sono‐Enhanced Nanozyme Catalysis Drives ROS‐Mediated Pathogen Killing and Mitophagy‐Linked Inflammation Control in Bacterial Pneumonia

Advanced Science, EarlyView.
Nebulized BN@NF nanozymes integrate boron nanosheets with Nd‐doped iron phosphide to form a sono‐magneto‐responsive Z‐scheme heterostructure. Under ultrasound and magnetic activation, BN@NF amplifies ROS generation, eradicates bacteria, disrupts biofilms, and reshapes pulmonary inflammation through NF‐κB suppression, mitophagy promotion, and M1‐to‐M2 ...

The In Situ Electrochemical−Chemical Cascade Strategy for Pyruvic Acid Synthesis

Advanced Science, EarlyView.
By employing an “unsaturation−oxygen coordination engineering” strategy, the local coordination environment is regulated to achieve efficient electrochemical synthesis of H2O2. Importantly, an electrochemical−chemical coupled cascade strategy is utilized for the efficient preparation of pyruvic acid via lactic acid oxidation. ABSTRACT Hydrogen peroxide

Glutaminolysis Blockade‐Empowered Bimodal Nanodepot for Spatially Complementary Sono‐Thermal Ablation via PANoptosis and STING Activation Against Large Tumors

Advanced Science, EarlyView.
An injectable bimodal TCPD nanodepot disrupts glutaminolysis and TCA metabolism, sensitizing large tumors to spatially complementary sono‐thermal ablation for complete treatment coverage. This intervention induces mitochondrial and endoplasmic reticulum dysfunction, genotoxicity, and NAD+ depletion, converging to trigger PANoptosome assembly and ...
