Macromolecular Symposia, EarlyView.ABSTRACT Oil palm empty fruit bunches (OPEFB), a byproduct of the palm oil industry, have great potential in the circular economy, particularly for composite material production. Multilayer plastic waste from the bottled water industry presents significant environmental challenges.

Prevention of Early Onset of Breast Cancer With Ashwagandha
Molecular Carcinogenesis, EarlyView.ABSTRACT Prevention of breast cancer is feasible because many risk factors for this malignancy are known (e.g., family history, reproductive factors, etc.). Medicinal plants and/or their bioactive phytochemicals are attractive for the prevention of early onset of breast cancer due to their generally favorable safety profile.

Langmuir, 2019 A homologous series of Gemini surfactants, dimethylene-1,2-bis(alkyldimethyl-ammonium bromide) (referred to as n-2-n·2Br, n = 14, 16, and 18) and Fe- or lanthanide metal-based magnetic Gemini surfactants (abbreviated as n-2-n·2X, X = Fe, Ce, and Gd), were first synthesized.

Phase Behavior of Gemini Surfactants
Journal of Dispersion Science and Technology, 2003 Gemini surfactants are made up of two surfactant-like moieties connected by a spacer group. This article reviews their phase behavior, considering successively the thermotropism of pure gemini surfactants, the lyotropism in gemini surfactant/water mixtures, and the ability of gemini surfactants to give rise to microemulsions in the presence of oil and ...

AbstractThe literature, including patents, describing the emerging area of gemini surfactants is reviewed. The differences in structure/property relationships between gemini and comparable conventional surfactants are described and discussed in terms of their predicted performance properties. Supportive performance data are enumerated.

Angewandte Chemie International Edition, 2000
How easy it is to dismiss the humdrum surfactant! After all, its structure is unglamorous by present-day norms. And the surfactant has been entrenched in so many areas of commerce for so many decades that its chemistry might seem old and tired. The purpose of this review is to persuade the reader otherwise, all the while focusing on a remarkable new ...

Polymerizable Cationic Gemini Surfactant
Langmuir, 2006A polymerizable cationic gemini surfactant, [CH(2)=C(CH(3))COO(CH(2))(11)N(+)CH(3))(2)CH(2)](2).2Br(-), 1 has been synthesized and its basic interfacial properties were investigated (in water and in the presence of 0.05 M NaBr). For comparison, the properties of monomeric surfactant corresponding to 1, CH(2)=C(CH(3))COO(CH(2))(11)N(+)(CH(3))(3).Br ...

Gemini Surfactant Electrospun Membranes
Langmuir, 2009Our research demonstrates electrospun nonwoven fibrous scaffolds from a low molar mass gemini ammonium surfactant, N,N'-didodecyl-N,N,N',N'-tetramethyl-N,N'-ethanediyldiammonium dibromide (12-2-12). Cryogenic transmission electron microscopy (cryo-TEM) and solution rheological experiments revealed micellar morphological transitions of 12-2-12 in water ...

Gemini Surfactants with a Disaccharide Spacer
Journal of the American Chemical Society, 2001A gemini surfactant is an amphiphile possessing (in sequence) the following: hydrocarbon tail/polar group/spacer/polar group/hydrocarbon tail. Widespread interest in geminis has emerged recently from both industrial and academic laboratories. In the present contribution, two related families of geminis have been synthesized, both with trehalose, a ...
