Journal ArticleDOI
Self-assembling hydrogel scaffolds for photocatalytic hydrogen production.

TL;DR: This work reports on the light-driven production of hydrogen inside a hydrogel scaffold built by the supramolecular self-assembly of a perylene monoimide amphiphile and finds the emergent phenomenon that screening by the catalyst or the electrolytes led to two-dimensional crystallization of the chromophore assemblies and enhanced the electronic coupling among the molecules.
Journal ArticleDOI
Two-dimensional nanofluidics
Andrew R. Koltonow,Jiaxing Huang +1 more
TL;DR: Nanofluidics, which enables the manipulation of confined ions and electrolytes, has applications in electrochemical energy conversion and storage, biosensing, and water purification.
Journal ArticleDOI
Self-assembled two-dimensional nanofluidic proton channels with high thermal stability
TL;DR: Self-assembled clay-based 2D nanofluidic channels with surface charge-governed proton conductivity are reported, which should prove useful to the study of confined ionic transport, and will enable new ionic device designs.
Journal ArticleDOI
Self-dispersed crumpled graphene balls in oil for friction and wear reduction.
Xuan Dou,Andrew R. Koltonow,Xingliang He,Hee Dong Jang,Qian Wang,Yip-Wah Chung,Jiaxing Huang +6 more
TL;DR: For the first time to the authors' knowledge, such type of ultrafine particles made of crumpled, paper-ball–like graphene are reported, which indeed can self-disperse in lubricant oil, and exhibit stable and superior tribological performances.
Journal ArticleDOI
Supramolecular Packing Controls H2 Photocatalysis in Chromophore Amphiphile Hydrogels
Adam S. Weingarten,Roman V. Kazantsev,Liam C. Palmer,Daniel J. Fairfield,Andrew R. Koltonow,Samuel I. Stupp +5 more
TL;DR: In this article, the photocatalytic performance of perylene monoimide chromophore amphiphiles with different alkyl linker lengths separating their hydrophobic core and the hydrophilic carboxylate headgroup was investigated.
