Study of Foaming Properties and Effect of the Isomeric Distribution of Some Anionic Surfactants [PDF]

open access: yes, 2008
Using different reaction conditions of photosulfochlorination of n-dodecane, two samples of anionic surfactants of sulfonate type are obtained. Their micellar behavior has been already reported and the relationship between their isomeric distribution and

Nonionic Surfactants in Paper Electrophoresis

open access: yesClinical Chemistry, 1960
Abstract 1. A modification of the usual paper electrophoretic procedure has been made by including in the buffer medium 0.05 per cent of certain alkylphenyl ethers of polyethylene glycol. 2. This modified procedure yields electrophoretic patterns of blood serum proteins that may be subdivided into 12 fractions— albumin, α1-

Wetting of Coal by Nonionic Surfactant and Mixtures of Nonionic and Anionic Surfactants [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1983
Abstract The rates of wetting of coals with various carbon contents by aqueous nonionic surfactants and mixtures of nonionic and anionic surfactants were examined. It was found that the wetting rate of each coal decreased with an increase of the length of oxyethylene chain in the nonionic surfactant.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Micelle Formation and the Hydrophobic Effect [PDF]

open access: yes, 2004
The tendency of amphiphilic molecules to form micelles in aqueous solution is a consequence of the hydrophobic effect. The fundamental difference between micelle assembly and macroscopic phase separation is the stoichiometric constraint that frustrates ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Emulsion Stability of Heavy Oil with Surfactants and Nanoparticles

open access: yesImproved Oil and Gas Recovery, 2020
The recovered crude oil is often in form of an emulsion and the recovery is cut off when water to oil ratio exceeds a certain amount. The emulsions vary from water-in-oil to oil-in-water and the step that follows is to coalesce droplets to get two ...

Influence of surfactants on the electrohydrodynamic stretching of water drops in oil [PDF]

open access: yes, 2017
In this paper we present experimental and numerical studies of the electrohydrodynamic stretching of a sub-millimetre-sized salt water drop, immersed in oil with added non-ionic surfactant, and subjected to a suddenly applied electric field of magnitude ...

Cool Kitchen: Processing Starch and Eggshell Powder into Sustainable Coatings for Passive Daytime Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A food‐grade cooling composite made from starch and recycled eggshell powder offers a scalable, ultra‐low‐cost solution for passive daytime radiative cooling. Easily prepared using basic kitchen tools, this material empowers communities, even in areas with limited infrastructure, to stay cooler during worsening summer heat waves.
