Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

Advanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

A Magneto‐Mechanically Activated Nerve Guidance Conduit Promotes Peripheral Nerve Regeneration via TIMP1‐Mediated Membrane Tension Transfer

Advanced Functional Materials, EarlyView.
This study presents a magneto‐mechanical strategy that incorporates FP@MSCs into an aligned PCL/GelMA nerve guidance conduit. Magnetic stimulation increases membrane tension in FP@MSCs, triggering cytoskeletal remodeling, Schwann cell‐like differentiation, and TIMP1 secretion. TIMP1 activates ITGB1/CD63–FAK signaling in NE‐4C cells, increasing membrane

ANTIOXIDANT ACTIVITY DETERMINATION IN A LIPIDIC PEROXIDATION MODEL OF BUTTER INHIBITED BY ISOESPINTANOL

Vitae, 2009
The antioxidant activity (Φ) is defined as the slope of the simple linear regression of φ0/φi against the concentration μM, in an inhibition model of lipid peroxidation of butter at 60° C, where φi is the concentration effect of isoespintanol and φ0 is ...

THE VALUE OF PEROXIDE OF HYDROGEN IN THE TREATMENT OF CHRONIC GONORRHœA, ILLUSTRATED BY A CASE. [PDF]

JAMA: The Journal of the American Medical Association, 1892
During the past few years, the many articles on new drugs in the treatment of gonorrhœa leave nothing to be desired in this way. The present article contains nothing new, but simply gives the history of a case of chronic gonorrhœa arrested by the use of peroxide of hydrogen—a drug that is "going the rounds," probably to be discarded by reason of its ...

Oxygen Evolution Electrocatalysts with Trinuclear, Mixed‐Valence Iron Motifs on Electronically Aligned Carbon Dots

Advanced Functional Materials, EarlyView.
Trinuclear iron oxo‐bridged catalytic ensembles stabilized by aspartic‐acid‐derived carbon dots provide an effective platform for alkaline oxygen evolution. Mixed‐valence charge balancing, inner‐sphere charge transport, and work‐function alignment within the N/O‐rich carbon framework promote cooperative Fe‐site chemistry and efficient OER ...

Re-evaluation of Peroxide Value as an Indicator of the Quality of Edible Oils

Journal of the Food Hygienic Society of Japan (Shokuhin Eiseigaku Zasshi), 2007
The oxidation of oils has important effects on the quality of oily foods, such as instant noodles. In particular, the generation of aldehydes, which accompanies the oxidation of oils, is one of the first factors to reduce food quality. We examined various indicators of oil quality during temperature-accelerated storage and found that peroxide value ...

Nanoamphizymes: Self‐Assembled Amphiphilic Enzymatic Nanomaterials for High‐Performance Biocatalysis and Biosensing

Advanced Functional Materials, EarlyView.
An amphiphilic GOx nanoamphizyme was constructed by covalently introducing hydrophobic PPNI linkers onto GOx, enabling spontaneous self‐assembly into tunable nanoparticles. Mild crosslinking further stabilized the assemblies and enhanced catalytic performance and stability.

Single‐Cell Resolution Mapping of Osteoarthritis‐Associated Chondrocyte Dynamics Using a High‐Density CMOS MEA Platform

Advanced Healthcare Materials, EarlyView.
Single‐cell and spatially resolved impedance mapping using a high‐density CMOS‐MEA platform enables non‐invasive monitoring of osteoarthritis‐associated chondrocyte dynamics. Continuous label‐free measurements reveal heterogeneous remodeling behaviors, including proliferation, migration, and phenotypic transitions, establishing a powerful approach for ...

Use Rosemary (Rosemarinus Officinalis L.) As Antioxidant And Antifungal To Extend The Shelf Life Of Cakes [PDF]

المجلة العلمية لكلية التربية النوعية - جامعة المنوفية
The purpose of this study was to determine how adding rosemary oil influenced the chemical, microbiological, and sensory properties of cakes. Three samples were prepared: one with pure oil (-), one with oil plus BHT (+), and one with rosemary oil (R).
