Abstract:

Two new homologous series of amphiphiles–five long-chain, three-headed amphiphiles [3CCb14, 3CCb16, 3CCb18, 3CCb20, 3CCb22; CH3(CH2)n-1OCONHC(CH2CH2COOH)3, n = 14, 16, 18, 20, 22], and six branched-chain, three-headed amphiphiles [3CCb1(7,7), 3CCb1(8,8), 3CCb1(9,9), 3CCb1(10,10), 3CCb1(11,11), 3CCb1(12,12); (CH3(CH2)n-1)2CHOCONHC(CH2CH2COOH)3, n = 7, 8, 9, 10, 11, 12]–were synthesized. The synthesis of the 3CCbn series was accomplished in two steps from Weisocyanate™ and the long chain alcohol in good yields of chromatographed products (65–81%). The 3CCb1(n,n) series was similarly synthesized

Highly concentrated micellar casein concentrate (HC-MCC), a potential ingredient for cheese making, containing ~20% casein with ~70% of serum proteins removed by microfiltration, and diafiltration of skim milk, and then further concentrated by vacuum evaporation.

Abstract:

Hydrogen sulfide (H2S) is an endogenously produced signaling gas involved in numerous cellular functions. At the appropriate concentration, exogenous administration of this gasotransmitter regulates vasodilation, promotes angiogenesis of endothelial cells, and generally exhibits beneficial effects as an anti-inflammatory and antioperoxidative agent. H2S is also capable of acting as a gaseous chemotherapeutic agent. Therefore, the therapeutic potential of exogenous delivery of H2S is vast. The delivery of H2S is complicated by its gaseous nature. Under physiologically relevant conditions, H2S

It is well-documented that buttermilk has poor coagulation properties due to changes that occur to the casein micelles during the butter-making process.

Abstract:

The paper describes synthesis method and colloid-chemical properties of novel α-amino acid based polyesters with controllable hydrophilic-lipophillic balance. Glutamic acid and diols of different nature based polyesters were obtained via low-temperature activated polyesterefication. Such polymers are able to form micellar structures in self-stabilized water dispersion. Solubilization of water insoluble dyes Sudan and toluene in polymer water solution was studied. Due to micelle forming ability and prognosticated biodegradability to non-toxic products, obtained polymers are promising mater

Abstract:

A própolis verde brasileira é um dos produtos de abelha mais consumidos no mundo devido às suas atividades antioxidantes, antiinflamatórias, antimicrobianas e antitumorais. Coletada pela espécie Apis mellifera, esta própolis possui a maior porcentagem de Artepilina C dentre as demais própolis. A molécula, derivada do ácido cinâmico, possui dois grupos prenilados, o que favorece a afinidade do composto pelo ambiente lipofílico. Um grupo carboxila também está presente na estrutura da Artepilina C, tornando-a um composto sensível ao pH, o que pode modular sua atividade biológica relacionada a int

De nos jours, l'idée qu'une molécule puisse être utilisée comme élément actif dans un dispositif électronique stimule l'activité scientifique des laboratoires de chimie et de physique dans le monde entier. Les demandes technologiques en termes de capacité de stockage d'informations sont en croissance exponentielle et repose maintenant sur le développement des nanosciences. L'objectif consiste à stocker les données aussi rapidement que possible dans un dispositif aussi petit que possible. Une des stratégies les plus prometteuses est basée sur le concept de bistabilité moléculaire : la commutati

Abstract:

As saponinas são tensoativos naturais, caracterizadas principalmente por sua atividade espumógena. Ilex paraguariensis A. St. Hil, conhecida como "erva-mate", é uma espécie vegetal rica em saponinas e de importância econômica e cultural para este Estado. Estudos anteriores demonstraram que os frutos imaturos de I. paraguariensis, uma parte do vegetal sem valor comercial, apresenta teores mais elevados de saponinas que as folhas da erva-mate. O objetivo deste trabalho foi avaliar a potencialidade das saponinas dos frutos imaturos de I. paraguariensis como adjuvante espumógeno, sob o ponto de vi

Abstract:

Dans le contexte du développement durable, l’'utilisation des ressources renouvelables, biodégradable et peu toxique, est particulièrement recherchée. En particulier, la littérature montre que les molécules amphiphiles biosourcées avec une tête sucre, type glycolipides, sont d'excellents candidats pour substituer les tensioactifs pétrochimiques actuellement utilisés massivement en formulation. Pour limiter le criblage expérimental et orienter le choix des synthèses de telles molécules, une démarche prédictive à partir de l'analyse de la structure moléculaire permettrait d'anticiper les proprié

Les micelles de caséines, composées de caséines, minéraux et eau, sont en équilibres dynamiques, elles échangent en permanence de leur matière avec leur environnement. Les micelles de caséines possèdent d’intéressantes fonctionnalités pour la fabrication de produits laitiers, telles que leur capacité à stabiliser des émulsions et à former des gels sous l’action de la présure. Des changements environnementaux, variations de pH, additions de sels ou d’agents chélatants, affectent les équilibres des micelles et induisent des modifications de leurs compositions et propriétés colloïdales.

Abstract:

Recent advances in nanoscience and nanotechnology have provided the scientific community with exciting new opportunities to rationally design and fabricate materials at the nanometer scale with drastically different properties as compared to their bulk counterparts. In this dissertation, several challenges have been tackled in aspects related to nanoparticle (NP) synthesis and characterization, allowing us to make homogenous, size- and shape-selected NPs via the use of colloidal chemistry, and to gain in depth understanding of their distinct physical and chemical properties via the synergistic

Mixed association of calix[4]resorcinarene with ethyl sulfonate groups on the lower rim and dimethylaminomethyl groups on the upper rim (CR) and cationic surfactant 4-aza-1-hexadecyl-azoniabicyclo[2.2.2]octane bromide (DABCO-16) is studied by methods of tensiometry, conductometry, potentiometry and NMR spectroscopy at fixed CR concentration and varied surfactant concentration. Beyond ca. 0.4 mM of DABCO-16, mixed aggregates enriched by CR are proved to be formed due to electrostatic forces, while beyond ca. 5 mM, aggregates enriched by surfactant occur due to the hydrophobic effect.
