Electron Paramagnetic Resonance Spectroscopy to Evaluate the Oxidative Stability of Beer, Wine, and Oils

Molecules
Oxidative stability plays an important role in determining the quality of oxidation-sensitive foods and beverages such as beer, wine, and edible oils. Oxidation occurs through radical chain reactions producing off-flavors and leading to deterioration and

Elucidating the Mechanism behind the Enhancement of Persistent Luminescence in ZnGa2O4: Cr3+ Nanoparticles upon H2O2 Exposure

Advanced Optical Materials, EarlyView.
ABSTRACT Persistent luminescence (PersL) materials exhibit prolonged emission of light, lasting from seconds to hours after stopping the excitation. At the nanoscale, they have attracted considerable interest for applications in in vivo imaging, photodynamic therapy, and biosensing.

Biodegradable Carbonate Nanogels Loaded with Anti MFAP‐5 siRNA for Anti‐stromal Therapy of Hepatocellular Carcinoma

Advanced Science, EarlyView.
Polycarbonate nanogels enable lipid‐free delivery of anti‐MFAP‐5 siRNA into cancer‐associated fibroblasts (CAF) in hepatocellular carcinoma. In a cirrhotic murine model, this approach silences MFAP‐5, reduces fibroblast activation, and suppresses tumor growth by inhibiting NOTCH/Hes1‐driven angiogenesis. CAF‐targeted MFAP‐5 RNAi and conserved signaling

NIR‐Activatable Domino Cascade Catalysis Nanozyme Reactor for Multi‐Mechanism Synergistic Immunotherapy in Bladder Cancer

Advanced Science, EarlyView.
This study presents an intravesical delivery strategy of ferroptosis‐ and immunity‐inducing nanozyme‐loaded thermoresponsive hydrogels (FMCC@PNH) for enhanced bladder cancer therapy. Abstract Current intravesical therapies for bladder cancer after resection are limited by poor tissue penetration, off‐target effects, and insufficient efficacy.

Electron paramagnetic resonance as a tool to determine the sodium charge storage mechanism of hard carbon

Nature Communications
Hard carbon is a promising negative electrode material for rechargeable sodium-ion batteries due to the ready availability of their precursors and high reversible charge storage. The reaction mechanisms that drive the sodiation properties in hard carbons

Electron paramagnetic resonance detected via magnetization measurements

, 2005
Presented are magnetization measurements on a crystal of Fe8 single-molecule magnets using a Hall probe magnetometer. Irradiation with microwaves at frequencies of 92 and 110-120 GHz leads to the observation of electron paramagnetic resonance (EPR ...

Wide‐Range Adaptive Metal Oxide for Hydrogen Sulfide Detection From Earth to Space‐Like Environments

Advanced Science, EarlyView.
This work presents a gas sensing platform based on Cu‐doped SnO2 microspheres that operates reliably from ambient to space‐like conditions. The sensor maintains performance across vacuum and cryogenic environments, bypassing traditional oxygen‐mediated mechanisms, utilizing direct chemisorption and interfacial charge transfer.

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

Advanced Science, EarlyView.
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 ...
