Colloidal self-assembly of soft neural interfaces from injectable photovoltaic microdevices

Mahmut Selman Sakar, Zhangjun Huang, Murat Kaynak, Haiyan Jia

Biomimetic retinas with a wide field of view and high resolution are in demand for neuroprosthetics and robot vision. Conventional neural prostheses are manufactured outside the application area and implanted as a complete device using invasive surgery. He ...

Liquid Nitrogen-Mediated Thermal Shock for Instantaneous Detachment of Multi-walled Carbon Nanotube Films from Substrates and Their Application in Supercapacitors

Paul Joseph Dyson, Zhaofu Fei, Zhangjun Huang, Haiyan Jia

Pristine multiwalled carbon nanotube (MWNT) films have a range of important applications. Currently, vacuum filtration is the main method used to prepare MWNT films, which limits their large-scale production. Solvent evaporation is an alternative method us ...

Sustainable, Reshapable Surfactant-Polyelectrolyte Plastics Employing Water as a Plasticizer

Paul Joseph Dyson, Zhaofu Fei, Antoine Philippe Van Muyden, Zhangjun Huang, Haiyan Jia

Natural polymers such as those present in foods contain abundant noncovalent intra- and intermolecular interactions, notably hydrogen bonds, which make them rigid when dry, but on exposure to water soften, due to disruption of these interactions. This soft ...

Ionic liquid containing electron-rich, porous polyphosphazene nanoreactors catalyze the transformation of CO2 to carbonates

Paul Joseph Dyson, Zhaofu Fei, Felix Daniel Bobbink, Zhangjun Huang, Jorge Gustavo Uranga, Haiyan Jia, Yefeng Wang

We show that ionic liquids (ILs) interact with electron-rich, porous polyphosphazene (PPZ), to form hybrid PPZ-IL nanoreactors able to simultaneously capture and transform CO2 into carbonates. The PPZ nanospheres swell in organic solvents and effectively a ...

Bilayered polyurethane/dipole-dipole and H-bonding interaction reinforced hydrogels as thermo-responsive soft manipulators

Paul Joseph Dyson, Zhaofu Fei, Zhangjun Huang, Xunhui Wang, Haiyan Jia

Dipole-dipole and hydrogen-bonding interaction reinforced (DHIR) hydrogels that demonstrate both excellent thermo-responsive volume change and high mechanical strength have been developed. Their thermo-responsive volume change originates from the balance b ...

Unconventional Tough Double-Network Hydrogels with Rapid Mechanical Recovery, Self-Healing, and Self-Gluing Properties

Paul Joseph Dyson, Zhaofu Fei, Zhangjun Huang, Xunhui Wang, Haiyan Jia

Hydrogels are polymeric materials that have a relatively high capacity for holding water. Recently, a double network (DN) technique was developed to fabricate hydrogels with a toughness comparable to rubber. The mechanical properties of DN hydrogels may be ...
