Cleavable Cationic Gemini Surfactants

, 2012
This research project concerns investigations of ester-containing cationic gemini surfactants (esterquat and betaine ester types). These dimeric surfactants are compared with their monomeric counterparts.

Wearable Morphology‐Adaptive in‐Ear Device With Active Cleansing Capability for Multimodal Health Monitoring

Advanced Materials, EarlyView.
We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

Advanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Single‐Particle FRET Probes Heterogeneity in the Ligand Shell of Colloidal Perovskite Quantum Dots

Advanced Materials, EarlyView.
Single‐particle, single‐molecule Förster resonance energy transfer turns dye‐tagged ligands into nanorulers for the otherwise elusive organic shell of CsPbBr3 quantum dots. Distance variations within individual particles reveal pronounced local heterogeneity, while changes in the surrounding ligand chemistry shift the average dye–surface separation ...

Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

Advanced Materials, EarlyView.
Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.

Interface Engineering of Porous Transport Layer‐Catalyst Layer in Proton Exchange Membrane Water Electrolyzers: A Comprehensive Review

Advanced Materials Interfaces, EarlyView.
The PTL–CL interface plays a decisive role in PEMWE performance by governing electron conduction, water supply, oxygen removal, catalyst utilization, and interfacial stability. This review summarizes interface‐related resistance sources, characterization methods, and engineering strategies, highlighting rational PTL–CL interface design for low‐cost ...

MODELING THE INFLUENCE OF SURFACTANT ARCHITECTURE ON THE CRITICAL MICELLE CONCENTRATION OF DOUBLE-HEADED AND GEMINI SURFACTANTS

, 2009
Monte Carlo simulations have been used in the past to investigate a variety of surfactant systems; however, there is little published literature for double-headed and gemini surfactants with asymmetric tails.
