Bound Water as a Reinforcing Element for Ultra‐Strong Polyacrylamide

open access: yesAdvanced Science, EarlyView.
Rather than acting as a conventional plasticizer, bound water serves as a reinforcing element in polyacrylamide by constructing strong PAM–water–PAM hydrogen‐bond networks. This water‐mediated architecture delivers ultra‐high mechanical strength and exceptional flame resistance, redefining the role of water in polymer reinforcement.

Assessment of Direct Steam Generation Technologies for Solar Thermal Augmented Steam Cycle Applications

open access: yesEnergy Procedia, 2014
AbstractA conceptual design study was performed to quantitatively evaluate a range of solar augmented steam cycle design options for natural gas combined-cycle (NGCC) and pulverized coal power plants. Solar augmented steam cycle options were modeled for two direct steam generation (DSG) solar technologies: 500°C line-focus (parabolic trough or linear ...

Nanometer Layer Coating to Lactose Particles for Optimization of Dexamethasone Pulmonary Delivery

open access: yesAdvanced Science, EarlyView.
Nanometer layer coating (NLC) was investigated and its mechanism illustrated by advanced characterization techniques. The effects and application for the inhalation of dexamethasone (DEX) were demonstrated through in vitro and in vivo evaluation. This approach increased DEX bioavailability and enabled the dose to be reduced to 1/30 of the intravenous ...
