Intramolecular Down‐ and Up‐Conversion in Dimeric Tetracene Complexes Centered via Platinum(II) and Palladium(II)

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐tetracene dimeric complexes are synthesized through the pyridyl coordination to either Pt(II) or Pd(II). Photophysical properties are systematically compared as a function of the metal using steady‐state and time‐resolved spectroscopy. The Pt(II) dimer exhibits efficient intramolecular singlet fission and subsequent intramolecular up‐conversion ...

A SIMPLE AND ECONOMICAL PROCEDURE FOR THE PURIFICATION OF IMMUNOGLOBULIN Y FROM EGG YOLK BY T-GEL CHROMATOGRAPHY

open access: yesIranian Journal of Allergy, Asthma and Immunology, 2000
The use of immunoglobulin Y (IgY) instead of polyclonal antibodies prepared in mammals has been reported recently. These antibodies are found to have better properties in terms of specificity and ease of large scale production.

A Visible Light‐Responsive Hydrogel to Study the Effect of Dynamic Tissue Stiffness on Cellular Mechanosensing

open access: yesAdvanced Functional Materials, EarlyView.
A visible light‐responsive polyacrylamide‐azobenzene hydrogel enables safe, reversible stiffness control for studying cell mechanobiology without harmful UV exposure. This approach reveals stem cells respond rapidly to mechanical changes, showing altered shape and protein distribution within one hour.

Superionic Disulfonic Acid Polymers

open access: yesAdvanced Functional Materials, EarlyView.
A strategy is presented to enhance the mechanical and ion transport properties of acid‐functionalized polymers through controlled polymerizations of precisely designed disulfonic acid monomers with well‐defined functional group arrangements. This approach allows for fine control over molecular interactions, and unexpected hydrophobic characteristics ...

Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels

open access: yesAdvanced Functional Materials, EarlyView.
A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

Liquid-gel chromatography on lipophilic-hydrophobic Sephadex derivatives

open access: yesJournal of Lipid Research, 1970
Hydrophobic long-chain alkyl ethers of Sephadex have been synthesized and tested for use in liquid chromatography. With columns prepared in such polar solvents as methanol, reversed-phase systems are obtained where compounds separate in order of ...

Deciphering a New Electrolyte Formulation for Intelligent Modulation of Thermal Runaway to Improve the Safety of Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Diels‐Alder clicks chemistry addresses thermal runaway in lithium‐ion batteries. A thermoresponsive electrolyte with lithium salt in vinylene carbonate (VC) and 2,5‐dimethylfuran (DMFu) operates at room temperature but undergoes Diels‐Alder reactions at high temperatures, enabling a two‐step safety mechanism: a warning phase at ≈100 °C and complete ...
