A theoretical study of Gemini surfactant phase behavior

open access: yes, 2020
Gemini surfactants are a relatively new type of surface active material, characterized by multiple hydrophilic head groups. The phase behavior of a Gemini surfactant lattice model is studied by Monte Carlo simulations and quasichemical ͑QC͒ calculations.

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

Clinical biological and genetic heterogeneity of the inborn errors of pulmonary surfactant metabolism [PDF]

open access: yes, 2001
Pulmonary surfactant is a multimolecular complex located at the air-water interface within the alveolus to which a range of physical (surface-active properties) and immune functions has been assigned. This complex consists of a surface-active lipid layer
