Are Grignard Reactions in Deep Eutectic Solvents Interface-Driven? [PDF]

Angew Chem Int Ed Engl
Experimental and molecular dynamics studies of acetophenone, alongside a computational analysis of i‐PrMgCl in a biphasic ChCl:2Gly DES/THF solution, offer valuable insights into the remarkable efficiency of the Grignard reaction under these conditions.

Bio-Based Surfactants via Borrowing Hydrogen Catalysis. [PDF]

Chemistry
A borrowing hydrogen approach to produce bio‐based surfactants is described. Using amino acids and common alcohols without protecting groups, surfactants are synthesized in one step with a ruthenium catalyst, achieving nearly ideal atom economy, including Gemini surfactants and a quaternary ammonia salt, with remarkable surfactant properties and ...

Stirring Without Stirrers: Polymer Fouling-Driven Mass Transport Unlocks Order-of-Magnitude Gain in Electrochemiluminescence. [PDF]

Adv Sci (Weinh)
Strategic electrode fouling enhances mass transport, primarily through electrochemically actuated lateral density gradients. Engineered fouling induces flow velocities up to 0.4 cm s⁻¹ in otherwise quiescent systems. Sub‐millimeter plastic features boost local rates by up to 290%, while micrometer‐scale arrays yield a 30% net electrolysis gain ...

Innovative Real-Time Flow Sensor Using Detergent-Free Complex Emulsions with Dual-Emissive Semi-Perfluoroalkyl Substituted Α-Cyanostilbene. [PDF]

Adv Sci (Weinh), 2023
A semi‐perfluoroalkyl substituted amphiphilic α‐cyanostilbene, CNFCPEG, exhibits intriguing aggregation‐dependent dual fluorescence properties, blue and green emission at low and high aggregation levels, respectively. Complex emulsions with CNFCPEG are stable without external surfactants and show morphology‐dependent emission at the fluorocarbon/water ...

Design and Characterization of Model Systems that Promote and Disrupt Transparency of Vertebrate Crystallins In Vitro

Advanced Science, Volume 10, Issue 35, December 15, 2023., 2023
Human vision is enabled through the transmission, refraction, and color‐sensing of light through the eye. Combining analytical and computational methods, the properties and interactions of lens crystallins that enable their organized, dense‐packing into a transparent microstructure are explored.

Composition, microstructure, rheology, and meltdown behavior of commercial nondairy frozen desserts. [PDF]

J Food Sci
Abstract The demand for nondairy and plant‐based products has increased, but there is still a need for more information about and improvement in these products, especially when it comes to frozen desserts. Similar to ice cream, which simultaneously is an emulsion, dispersion, and foam, nondairy frozen desserts also have a complex structure.

Measuring the Interactions and Influence of Amphipathic Copolymers with Lipid Monolayers and Bilayers as Models of Biological Membranes

Macromolecular Chemistry and Physics, Volume 224, Issue 24, December 2023., 2023
A library of amphipathic methacrylic copolymers is synthesized and tested for their effects on models of cell membranes. The polymer‐membrane interactions are studied using complementary techniques in Langmuir monolayers, neutron reflectometry, and QCM‐D.

Effect of Amplitude on the Surface Dilational Visco-Elasticity of Protein Solutions

Colloids and Interfaces, 2018
Harmonic drop surface area oscillations are performed at a fixed frequency (0.1 Hz) to measure the dilational visco-elasticity for three proteins: β-casein (BCS), β-lactoglobulin (BLG), and human serum albumin (HSA).

Controlling nonspecific protein adsorption in a plug-based microfluidic system by controlling interfacial chemistry using fluorous-phase surfactants [PDF]

, 2005
Control of surface chemistry and protein adsorption is important for using microfluidic devices for biochemical analysis and high-throughput screening assays. This paper describes the control of protein adsorption at the liquid-liquid interface in a plug-
