Organophilic clays and their application in atrazine adsorption [PDF]
Atrazine’s adsorptive capabilities make the use of clays practical and effective. Three types of organophilic clays modified by cationic surfactants with the ability of one of these clays to adsorb atrazine in an aqueous medium are discussed in this work.

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

We studied a system formed by a mixture of a thermoresponsive negatively charged graft copolymer (Alg-g-PNIPAAm) with a brush-type structure, and an oppositely charged surfactant (DTAB), in bulk and at the air-solution interface. We performed experiments

ABSTRACT The hydrophilic–lipophilic difference (HLD) for ionic surfactant microemulsions (μEs) can be interpreted as the curvature normalized by the tail length parameter (L), if it is corrected by a factor “bi”, bi·HLD = HLDcurv = HLDbi = bi·ln(S) – kbi·EACN + Ccbi, with bi and kbi representing the curvature sensitivity to changes in salinity (S, g ...

Action of Monomeric/Gemini Surfactants on Free Cells and Biofilm of Asaia lannensis
We investigated the biological activity of surfactants based on quaternary ammonium compounds: gemini surfactant hexamethylene-1,6-bis-(N,N-dimethyl-N-dodecylammonium bromide) (C6), synthesized by the reaction of N,N-dimethyl-N-dodecylamine with 1,6 ...

Growth and reductive transformation of a gold shell around pyramidal cadmium selenide nanocrystals
We report the growth of an unstable shell-like gold structure around dihexagonal pyramidal CdSe nanocrystals in organic solution and the structural transformation to spherical domains by two means: i) electron beam irradiation (in situ) and (ii) addition

Poly(N‐isopropylacrylamide) (PNIPAm)‐based copolymer microgels with incorporated anionic, cationic, and neutral comonomers served as multifunctional colloidal building blocks for the formation of dynamic structural colors. Precise control over synthesis parameters and self‐assembly behavior allow for the fine‐tuning of the reflected color across the ...

This study explores scalable methods of incorporating graphene nanoplatelets into SBR latex with or without a surfactant, using either powder or a masterbatch. Results show that combining a masterbatch with the surfactant DTAB improves vulcanization speed, mechanical strength, hardness, thermal conductivity, and resistance to aging.
