Bioinspired Universal Flexible Elastomer-Based Microchannels
Wu, Feng; Chen, Songyue; Chen, Baiyi; Wang, Miao; Min, Lingli; Alvarenga, Jack; Ju, Jie; Khademhosseini, Ali; Yao, Yuxing; Zhang, Yu Shrike; Aizenberg, Joanna; Hou, Xu (Wiley, 2018)Flexible and stretchable microscale fluidic devices have a broad range of potential applications, ranging from electronic wearable devices for convenient digital lifestyle to biomedical devices. However, simple ways to ... -
Design of anti-icing surfaces: smooth, textured or slippery?
Kreder, Michael Joseph; Alvarenga, Jack; Kim, Philseok; Aizenberg, Joanna (Springer Nature, 2016)Passive anti-icing surfaces, or icephobic surfaces, are an area of great interest because of their significant economic, energy and safety implications in the prevention and easy removal of ice in many facets of society. ... -
Dynamic daylight control system implementing thin cast arrays of polydimethylsiloxane-based millimeter-scale transparent louvers
Park, Daekwon; Kim, Philseok; Alvarenga, Jack; Jin, Keojin; Aizenberg, Joanna; Bechthold, Martin (Elsevier BV, 2014)The deep building layouts typical in the U.S. have led to a nearly complete reliance on artificial lighting in standard office buildings. The development of daylight control systems that maximize the penetration and optimize ... -
Inhibition of ice nucleation by slippery liquid-infused porous surfaces (SLIPS)
Wilson, Peter W.; Lu, Weizhe; Xu, Haojun; Kim, Philseok; Kreder, Michael Joseph; Alvarenga, Jack; Aizenberg, Joanna (Royal Society of Chemistry (RSC), 2013)Ice repellent coatings have been studied and keenly sought after for many years, where any advances in the durability of such coatings will result in huge energy savings across many fields. Progress in creating anti-ice ... -
Pneumatically adaptive light modulation system (PALMS) for buildings
Hinz, K.; Alvarenga, Jack; Kim, Philseok; Park, D.; Aizenberg, Joanna; Bechthold, Martin (Elsevier BV, 2018)This research introduces a novel approach to control light transmittance based on flexible polydimethylsiloxane (PDMS) films that have been plasma-treated such that micro-scale surface features have a visual effect as the ... -
Secrets revealed — Spatially selective wetting of plasma-patterned periodic mesoporous organosilica
Wang, Wendong; Burgess, Ian; Hatton, Benjamin D.; Alvarenga, Jack; Aizenberg, Joanna (Canadian Science Publishing, 2012)We report a simple method to pattern wetting properties on thin films of periodic mesoporous organosilica (PMO). A hydrophobic methane PMO thin film was covered by masks and exposed to oxygen plasma to make the unmasked ... -
Self-Replenishing Vascularized Fouling-Release Surfaces
Howell, Caitlin; Vu, Thy L.; Lin, Jennifer; Kolle, Stefan; Juthani, Nidhi; Watson, Emily; Weaver, James C.; Alvarenga, Jack; Aizenberg, Joanna (American Chemical Society (ACS), 2014)Inspired by the long-term effectiveness of living antifouling materials, we have developed a method for the self-replenishment of synthetic biofouling-release surfaces. These surfaces are created by either molding or ... -
Stability of Surface-Immobilized Lubricant Interfaces under Flow
Howell, Caitlin; Vu, Thy L.; Johnson, Christopher; Hou, Xu; Ahanotu, Onyemaechi; Alvarenga, Jack; Leslie, Daniel; Uzun, Oktay; Waterhouse, Anna; Kim, Philseok; Super, Michael; Aizenberg, Michael; Ingber, Donald Elliot; Aizenberg, Joanna (American Chemical Society (ACS), 2015)The stability and longevity of surface-stabilized lubricant layers is a critical question in their application as low- and nonfouling slippery surface treatments in both industry and medicine. Here, we investigate lubricant ...
