Colloidal Heterostructures Enable Interfacial Transport of Immiscible Molecules in Printable Organohydrogels

Advanced Materials, EarlyView.
Multiphase printable organohydrogels with tunable microstructures are developed to control molecular transport pathways for immiscible cargo. The tortuosity and domain size of the colloidal phases are tuned by adjusting temperature and shear during processing, which enables the tailoring of diffusion kinetics due to different transport pathways.

Effects of Soil-Foundation-Bridge Interaction Subjected to Spatially Varying Earthquake Ground Motion [PDF]

, 2013
The primary purpose of this study is to investigate stochastic responses of a cable-stayed bridge which is built on the Mississippi River in 1987 in USA, subjected to the spatially varying earthquake ground motion by using the finite element method ...

Integrated Lead/Iodine Management for Sustainable Perovskite Solar Modules

Advanced Materials, EarlyView.
Perovskite solar modules face environmental risks from lead and iodine leakage. A dual‐function adsorbent—porphyrin‐modified whitlockite nanocomposites—effectively captures iodine and Pb2+, even under severe damage. Combined with a semi‐closed recycling process, it recovers 96.9% high‐purity PbI2 and reduces residual Pb2+ to <10 ppb, offering an ...

Ultra‐Sensitive Nanofiber‐Based Triboelectric Nanogenerator for Energy Harvesting and Self‐Powered Sensing

Advanced Materials, EarlyView.
A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...

Effect of soil–structure interaction on the reliability of reinforced concrete bridges

Ain Shams Engineering Journal, 2015
In the design of reinforced concrete (RC) bridges, the random and nonlinear behavior of soil may lead to insufficient reliability levels. For this reason, it is necessary to take into account the variability of soil properties which can significantly ...

Using the scaled boundary finite element method to model 2D time-dependent geotechnical engineering problems [PDF]

, 2005
The scaled boundary finite element method caters well for soil-structure interaction problems, but the formulation does not cater for the presence of changing pore pressures with time, body loads and tractions. A detailed formulation is presented in this

Progressive Collapse of Steel Structures Under Blast Loads Considering Soil-Structure Interaction

Shock and Vibration
This study focuses on the effect of soil-structure interaction on the occurrence of progressive collapse due to an external blast. Therefore, a 3-story fixed base steel moment-resisting frame structure was first modeled and subjected to an external blast
