PRODUCTION OF CARBON FIBERS FROM CASTILLA'S CRUDE-OIL DEASPHALTED BOTTOMS

open access: yesCT&F Ciencia, Tecnología & Futuro, 2002
Obtaining raw materials for the manufacturing of carbon fibers from Castilla's crude-oil deasphalted bottoms was achieved through thermal treatments carried out in inert atmosphere, at temperatures ranging from 573 K to 673 K.

Controlling Intestinal Organoid Polarity using Synthetic Dynamic Hydrogels Decorated with Laminin‐Derived IKVAV Peptides

open access: yesAdvanced Healthcare Materials, EarlyView.
Design rules are presented to control intestinal organoid polarity in fully synthetic hydrogels. The laminin‐derived IKVAV sequence is crucial to obtain correct intestinal organoid polarity. Increasing hydrogel dynamics further supports the growth of correctly polarized intestinal organoids, while a bulk level of stiffness (G’ ≈ 0.7 kPa) is crucial to ...

Hydrocolloid‐Based Multiwavelength Stretchable QD‐OLED Patch for Simultaneous Neonatal Jaundice and Dermatitis Treatment with Biosignal Monitoring

open access: yesAdvanced Healthcare Materials, EarlyView.
Comparison of therapeutic and diagnostic applications of a surface‐emitting light source with multiwavelength emission characteristics. Abstract Conventional light‐emitting‐diode‐based light sources suffer from rigidity, localized heating, and poor adaptability to skin deformation, limiting their use in skin‐attached medical devices.

Multivalent Protein Nanorings for Broad and Potent SARS‐CoV‐2 Neutralization

open access: yesAdvanced Healthcare Materials, EarlyView.
A protein‐only, modular multivalent nanoscaffold displaying 20 anchor points, decorated with two different binders (10 of each), targeting the SARS‐CoV‐2 receptor‐binding domain is presented. The construct self‐assembles into stable, biocompatible, homogeneous nanoparticles, exhibit synergistic binding with fM IC50 values. It also detects spike at 9 ng

Effective Penetration of the Oxidized Keratin‐Rebonding Materials Into Hair Shafts Based on Charge Conversion

open access: yesAdvanced Healthcare Materials, EarlyView.
We have developed a smart hair‐repair ingredient based on β‐carboxylic acid amide that undergoes negative‐to‐positive charge conversion under mildly acidic conditions. The initial negative charge facilitates deep penetration into the hair fiber, while the subsequent positive charge enables re‐bonding with sulfonate groups in damaged hair keratin.

A Hierarchically Structured, Stretchable, Anti‐Biofouling Encapsulation for Biodegradable Electronics

open access: yesAdvanced Healthcare Materials, EarlyView.
A soft, stretchable, anti‐biofouling encapsulant is developed by integrating organosilicon nanowire networks with microstructured biodegradable elastomers. The hierarchical surface exhibits superhydrophobicity and enhances water barrier properties by 420% over pristine polymers, while preserving mechanical integrity.
