The article deals with surfactants capable of forming an aerodispersive system, foam, under specific conditions as described below. Characteristics of surfactants usable as foaming agents are specified. Attention is paid to detergency and detergent effects of foams, wetting process, dispersion formation, stabilization of foams and stabilizers. Rheological properties of foams, more precisely volume increase and stability, are described. Methods for disinfection efficacy testing of foaming agents are presented. Advantages and disadvantages of using foams for disinfection are summarized: it is concluded that the use of foams in disinfection is universally advantageous and means a great advance in disinfection technology.

Analyzing the Effectiveness of Different Delivery Methods for Remineralization Agents in Pediatric Dental Health: A Systematic Review.
Cureus
December 2024
College of Dentistry, King Saud bin Abdulaziz University for Health Sciences, Riyadh, SAU.
Pediatric dental health is critically impacted by enamel demineralization and early-stage caries, with remineralization therapies playing a vital role in preventing progression. This systematic review evaluates the effectiveness of various delivery methods for remineralization agents in pediatric patients aged 3-15 years, focusing on varnishes, gels, foams, and sprays. Studies were included if they were randomized controlled trials (RCTs), cohort studies, or case-control studies involving pediatric patients with early-stage caries or enamel demineralization, while studies with non-pediatric populations, unrelated treatments, or significant methodological flaws were excluded.

A novel class of SiO aerogel-based resin composite with a self-formed foamy structure and an extremely low thermal conductivity, as well as excellent fire resistance, was fabricated via a room temperature and atmospheric pressure route. The self-formed foamy structure was achieved by utilizing SiO aerogel particles not only as a thermal insulative functional additive filler but also as nano-sized solid particles in a Picking emulsion system, adjusting the surface tension as a stabilizer at the interface between the two immiscible phases (liquid and air in this case). The results of foamy structure analyses via scanning electron microscopy, micro-CT, and N adsorption-desorption isotherms validate the successful generation of a micro-scale porous structure with the enhancement of the aerogel nano-scale solid particles at the wall as a stabilizer.

This study applied high hydrostatic pressure (HHP) treatment to buffalo milk casein to assess the influence of different pressure levels on its structural characteristics, physicochemical properties, and functional properties. The results showed that although HHP had no marked impact on the zeta potential and secondary structure, it altered the protein's spatial structure (primarily its tertiary structure), and improved dispersion properties (such as particle size, solubility, and turbidity), as well as foaming properties. Additionally, HHP improved the antioxidant activity and antibacterial activity against Escherichia coli.

Aqueous film-forming foam (AFFF) is a targeted product for liquid fuel fires and has the benefits of a long storage period and high fire extinguishing efficiency. However, because of the toxicity and bioaccumulation of the core raw material's long-chain fluorocarbon surfactant, traditional AFFF is being phased out. For this reason, three efficient AFFFs (F-1, F-2, and F-3; more details in Table 2) were designed using anionic surfactants (PBAF) with branched C perfluorinated chains, hexadecyltrimethylammonium bromide (CTAB), and dodecyl dimethyl betaine (BS-12) as core materials.

Per- and polyfluoroalkyl substances (PFAS)-containing firefighting foam have been used in stationary fire suppression systems for several decades. However, there is a lack of research on how to decontaminate PFAS-contaminated infrastructure and evaluate treatment efficiency. This study assessed the removal of PFAS from stainless steel pipe surfaces using different cleaning agents (tap water, methanol, and aqueous solutions containing 10 and 20 wt % of butyl carbitol (BC)) at different temperatures (20 °C, 40 °C, and 70 °C).
