The application of 35% hydrogen peroxide in intracoronal bleaching generates free radicals that shorten resin tags and weaken the bond strength of composite resin restorations. Although 35% sodium ascorbate can neutraliz...

Graphite was exfoliated to graphene by tip sonic using sodium cholate as a surfactant in the presence of Millipore water as a medium. The use of water as a solvent for exfoliation purposes is very important due to its en...

Free radical residue due to intracoronal bleaching using 35% hydrogen peroxide (HP) can be removed with 35% sodium ascorbate (SA) combined with surfactants. This study aimed to determine the effect of surfactant concentr...

Gemini surfactants are amphiphilic molecules formed by two polar heads and two hydrophobic tails joined by a spacer between the polar groups. Their molecular structure gives them particular physico-chemical properties in...

The impact of rhamnolipids (RL) biosurfactants presence on the phase-separation equilibrium, micellar properties and partitioning behavior of systems containing the aliphatic non-ionic surfactant Tergitol 15-S-7 (Tg7) wa...

ABSTRACT The aim of this study was to assess the vitality and lung function of preterm lambs. Twenty seven preterm lambs were divided in four groups. Group I (n=6) preterm lambs/ control; group II (n=9) lambs born to mot...

Porous ammonium nitrate is frequently used for specific applications due to its porous structure when compared with conventional ammonium nitrate, however, its higher transportation costs increase overall operational exp...

Poly(allylamine)–dodecylsulfate complex (PA–DS) is able to form a stable and layered structure onto graphite electrodes and can efficiently retain negatively charged ions like ferrocyanide. In this con- text, Prussia...

Abstract In the aquaculture industry, biocides are routinely used to treat parasitosis in fish, and researchers are continually developing sustainable alternatives that can replace these harsh chemicals. In this context,...

Bilayer vesicles, such as liposomes and niosomes, are widely known as efficient delivery systems for drugs. Spherical vesicles consisting of amphipatic non-ionic surfactants named niosomes are arranged in one or more con...

The influence of the nonionic surfactant lauryl alcohol ethoxylate with 12 moles ethylene oxide (LAE-12OE) was evaluated on the Stratum corneum model biomembrane (SCMM) of shed snake skin (Bothrops jararaca and Spilotes ...

Se evaluó la reología y el tamaño de partícula de una preparación de surfactante pulmonar conocida como Surfacen® a una concentración de 25 mg/mL a las temperaturas de 23 y 37 °C y se estudió el efecto de la lio...

Se ha estudiado el efecto que tienen el método de remoción del surfactante y el contenido de titanio sobre la estructura y propiedades texturales de los materiales mesoporosos Ti-MCM-41. Los sólidos sintetizados fuero...

Stable and adherent polypyrrole films have been successfully electrodeposited onto aluminium electrode over a wide solution pH interval by using sodium bis(2-ethylhexyl) sulfosuccinate as dopant. The redox behaviour of t...

The biodiversity and biotechnological potential of microbes from central Argentinean halophilic environments have been poorly explored. Salitral Negro and Colorada Grande salterns are neutral hypersaline basins exploded ...

Abstract Restriction of fetal substrate supply has an adverse effect on surfactant maturation in the lung and thus affects the transition from in utero placental oxygenation to pulmonary ventilation ex utero. However, th...

Ginger and celery extracts are recognized anti-dandruff agents. Managing dandruff can be accomplished by creating a cleanser formulation. Shampoo contains an essential cleansing ingredient known as surfactant. SLS enable...

An increase in the frequency of 35% hydrogen peroxide (HP) application during intracoronal bleaching leads to a higher accumulation of free radical residues, which can negatively affect the bonding of composite resin. Th...

Background and Aim: Effective disinfection is critical for controlling pathogenic and opportunistic microorganisms in livestock environments. Didecyldimethylammonium chloride (DDAC), a quaternary ammonium compound, is wi...

Abstract Sensitive and accurate detection of biologically significant bilirubin is of great importance in the field of clinical diagnostics and disease monitoring. The present study introduces the TX-100 based nanomicell...
