The Effect of Temperature on the Adsorption of Non‐Ionic Surfactants and Non‐Ionic Surfactant Mixtures at the Air‐Water Interface

open access: yesBerichte der Bunsengesellschaft für physikalische Chemie, 1996
AbstractNeutron reflectivity has been used to study the effect of temperature on the adsorption of non‐ionic surfactants and non‐ionic surfactant mixtures at the air‐water interface. For a range of polyoxyethylene non‐ionic surfactants the adsorption is invariant with temperature in the range 25 to 50 c; however some subtle changes in the structure of ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Liposomes encapsulating polymeric chitosan based vesicles - a vesicle in vesicle system for drug delivery [PDF]

open access: yes, 2000
Drug delivery systems comprising vesicles prepared from one amphiphile encapsulating vesicles prepared from a second amphiphile have not been prepared previously due to a tendency of the bilayer components of the different vesicles to mix during ...

Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

open access: yesAdvanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

Non-ionic surfactants adsorption: structure and thermodynamics

open access: yesComptes Rendus. Géoscience, 2002
Adsorption of non-ionic surfactants from aqueous solutions has been studied for years because of its industrial relevance. These surfactants, made of an aliphatic part attached to a hydrophilic and polar chain, play an important role in diverse applications.

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

open access: yesAdvanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Transparent Inorganic–Organic Bilayer Neural Electrode Array and Integration to Miniscope System for In Vivo Calcium Imaging and Electrophysiology

open access: yesAdvanced Functional Materials, EarlyView.
This study presents the BioCLEAR system, a highly transparent and conductive neural electrode array composed of silver nanowires (AgNWs) and doped PEDOT:PSS, enabling neural recordings with minimal optical artifacts. When integrated with a GRIN lens, this cost‐effective neural implant allows simultaneous electrophysiological recording and GCaMP6‐based ...

Adsorption and Movement of Cypermethrin on Indian Soils Amended with Cationic, Non-Ionic and Anionic Surfactants

open access: yesAdsorption Science & Technology, 2004
Laboratory studies were conducted to determine the adsorption and movement of cypermethrin on surfactant-free (natural) and surfactant-amended soils at different micelle concentrations (below the CMC, at the CMC and above the CMC) using batch equilibrium
