Spin Noise Fluctuations from Paramagnetic Molecular Adsorbates on Surfaces [PDF]

open access: yes, 2006
The measurement of spin noise in nuclei was pioneered on bulk samples more than two decades ago. An ensemble of spins can produce a coherent signal at the frequency of a static magnetic field, known as spin noise, an effect due to the statistical polarization of small ensembles. The difficulty of these measurements is that the signal is extremely small,

Durable Bio‐Based Nanocomposite Coating on Urinary Catheters Prevents Early‐Stage CAUTI‐Associated Pathogenicity

open access: yesAdvanced Materials Interfaces, EarlyView.
A stable bio‐based nanocomposite coating for urinary catheters is developed using a simple, environmentally‐friendly sonochemical process. The coating, integrating antimicrobial, antibiofilm, and antioxidant properties, effectively tackled multiple early‐stage pathogenic factors associated with catheter‐associated urinary tract infections.

Magnetoimpedance based detection of L-band electron paramagnetic resonance in 2,2-diphenyl-1-picrylhydrazyl (DPPH) molecule [PDF]

open access: yesarXiv, 2020
Detection of electron paramagnetic resonance (EPR) using a microwave cavity resonating at a fixed frequency (between 9 and 10 GHz) remains the most popular method until now. Here, we report a cavity-less technique which makes use of only an impedance analyzer and a copper strip coil to detect L-band EPR (f = 1-3 GHz) in the standard EPR marker 2,2 ...

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.

open access: yesAdvanced Photonics Research, EarlyView.
Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

Insights on Advances in 3D Bioprinting for Peripheral Nerve Regeneration

open access: yesAdvanced Therapeutics, EarlyView.
Peripheral nerve injury is a common condition due to trauma that significantly impacts the life of the affected individual. This review explores the anatomy, classification, and pathophysiology of peripheral nerve injuries. It also discusses various types of nerve conduits and presents a detailed review of 3D bioprinted nerve conduits used in both in ...

LIBX‐A401: A Novel Selective Inhibitor of Acyl‐CoA Synthetase Long Chain Family Member 4 (ACSL4) and Its Binding Mode

open access: yesAngewandte Chemie, EarlyView.
The discovery of LIBX‐A401, a potent and selective ACSL4 inhibitor derived from rosiglitazone is reported. HDX‐MS reveals that LIBX‐A401 stabilizes the ACSL4 C‐terminus and alters the fatty acid (FA) gate domain. Consistently, photoaffinity labeling, molecular dynamics, and mutagenesis identify key binding residues within the FA pocket.

Advancing the Identification of Bioactive Molecules and the Construction of a Synergistic Drug Delivery System in Combating Lung Injury

open access: yesAdvanced Science, EarlyView.
Traditional Chinese Medicine (TCM), while holistic and historically esteemed, faces challenges in “miracle cures” due to slow onset, long cycles, and difficulty controlling quality. This study obtains the active ingredients, glabridin (GLA) and puerarin (PUE), from Ge‐Gen Decoction (GGD), developing a safe and effective drug delivery system, GLA‐PUE ...
