Interfacial Composition of Surfactant Aggregates in the Presence of Fragrance: A Chemical Trapping Study

Molecules, 2022
In recent years, there has been increasing interest in daily-use chemical products providing a pleasant scent. The added fragrance molecules may induce microstructural transitions of surfactant aggregates, which further affect the physical and chemical ...

Hot‐Film and Calorimetric Methods With Transient Heating for Measurement of High Biofluid Flow Rate

Advanced Functional Materials, EarlyView.
Accurate measurement of biofluid flow rate is vital for clinical diagnostics. We propose a transient heating strategy using short thermal pulses and peak temperature tracking to enhance the flow sensitivity of the hot‐Film and calorimetric methods. Simulations show how optimal heating time maximizes sensitivity across flow rates.

Enhancing mechanical performance of elastomeric vat-photopolymerized resins via functionalized cellulose nanocrystals

Virtual and Physical Prototyping
Vat photopolymerization (VP) additive manufacturing enables precise, reproducible fabrication of complex biomedical devices, yet elastomeric resins with robust mechanics remain scarce for constrained surgical settings.

Nanorheology of Interfacial Water during Ice Gliding

Physical Review X, 2019
The slipperiness of ice is an everyday-life phenomenon, which, surprisingly, remains controversial despite a long scientific history. The very small friction measured on ice is classically attributed to the presence of a thin self-lubricating film of ...

Interfacial properties of protein particles at fluid/fluid interfaces and relationship with the stability of foams and emulsions

Frontiers in Soft Matter, 2023
It is now well-known that the assembly of particles at fluid/fluid interfaces, and the resulting dynamical properties of such particle-laden interfaces can provide high stabilization of dispersed systems such as emulsions and foams. Here, we focus on the

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

High‐Resolution and Real‐Time In Situ Generation of Cellular Spheroids by Laser‐Assisted Bioprinting for Guided Microvascularization

Advanced Functional Materials, EarlyView.
Micro‐injection laser‐assisted bioprinting enables ultrafast and precise patterning of small endothelial cell spheroids by injecting a highly concentrated single‐cell suspension into GelMA/ColMA hydrogels. In co‐culture with fibroblasts, controlled pre‐vasculogenic network formation is obtained at microscale resolution.

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

Advanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,
