A Novel Perfused Full‐Thickness Human Skin Microphysiological System for Modeling Injury, Regeneration, Tumor Pathophysiology, and Therapeutics Development

Advanced Healthcare Materials, EarlyView.
What if human skin could remain fully alive and functional outside the body for weeks? A New Alternative Method (NAM) based on a vascularized full‐thickness skin microphysiological system achieves precisely this, preserving native vasculature, resident immunity, and metabolic activity for up to three weeks, while faithfully recapitulating radiation ...

Removal of Reactive Blue 19 using nonionic surfactant in cloud point extraction [PDF]

, 2014
Textile wastewater represents a serious environmental issue due to the presence of toxic dyes. The cloudpoint extraction, which involves the application of nonionic surfactants at temperatures above the cloudpoint, was applied in this research to remove ...

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Phase behavior of oil/water/nonionic surfactant systems [PDF]

, 2005
The phase behavior of oil/water/nonionic surfactant systems under the effect of temperature is usually only measured at an oil-to-water ratio of 1 : 1 (alpha = 0.5).

Stepwise On‐Surface Synthesis and Transformations of Two‐Dimensional Covalent Organic Frameworks by Controlled Thermal Stimuli

Advanced Materials, EarlyView.
The seminal transformation of a 2D‐COF (SURFCOF‐IMDEA1) into a 2D porous COF (SURFCOF‐IMDEA2) on Au(111) by a sequential C‐C coupling and ladderization triggered by thermal annealing steps at increasing temperatures is reported. Abstract The development of covalent organic frameworks (COFs) is currently a primary objective in materials science, taking ...

Increased Nonionic Surfactant Efficiency in Oil Recovery by Integrating with Hydrophilic Silica Nanoparticle [PDF]

, 2019
Nonionic surfactants are nonvolatile and benign chemicals widely used in the oil and gas industry. However, their huge loss especially under high temperature and high salinity conditions has limited their large-scale applications; thus, various additives

Wetting Process and Adsorption Mechanism of Surfactant Solutions on Coal Dust Surface

Journal of Chemistry, 2019
To determine the wetting process and wetting mechanism of different surfactant solutions on coal dust surface, four types of surfactants (anionic surfactant 1227, anionic surfactant AOS, amphoteric surfactant CAB-35, and nonionic surfactant CDEA) are ...
