Interaction between Injection Points during Hydraulic Fracturing

open access: yes, 2012
We present a model of the hydraulic fracturing of heterogeneous poroelastic media. The formalism is an effective continuum model that captures the coupled dynamics of the fluid pressure and the fractured rock matrix and models both the tensile and shear ...

Ion‐Electron Fusion Transparent Film for Interactive Soft Robotics

open access: yesAdvanced Science, EarlyView.
An ion‐electron fusion transparent film with stable conductivity, high optical transmittance, and a broad linear strain‐sensing range of up to 300% is developed, attributed to the synergistic effects of ion penetration and microcrack design. When applied to soft robots, this film imparts proprioceptive sensing and underwater visible light communication

Moisture Harvesting by the Structure Regulation of Hygroscopic Hydrogel for Energy and Water Sustainability

open access: yesAdvanced Electronic Materials, EarlyView.
Hygroscopic hydrogels are capable of utilizing the moisture from air, which can transfer the gaseous water to liquid by a surface phase transition. Taking advantage of this water, sustainable water production, thermal management, and electricity generation can be realized.

Keynote: Fatigue Hydraulic Fracturing

open access: yesProcedia Engineering, 2017
Abstract In this article, the concept of Fatigue Hydraulic Fracturing (FHF) is described, and its geothermal application is discussed. The basic idea behind fatigue fracturing is to vary the effective stress magnitudes at the fracture tip to optimize fracture initiation and growth. The optimization process can include lowering seismic radiated energy

Multifunctional Position and Stiffness Control of Soft Fluidic Actuators Using Supercooled Liquid

open access: yesAdvanced Intelligent Systems, EarlyView.
This work explores the use of supercooled liquid as a multifunctional working fluid for soft actuators to allow independent control of position and stiffness; the solution is used to both inflate the elastomer chambers while in liquid state and to achieve a dramatic increase in stiffness (up to 13 times) with rapid, reversible crystallization.

Hollow Fiber Ultrafiltraion and Granulated Activated Carbon Hydrocarbon Removal for Reverse Osmosis Pretreatment [PDF]

open access: yes, 2013
Hydraulic Fracturing is becoming an increasing prevalent technology in present society due its ability to produce cheap, clean natural gas as a viable fuel source. One public image draw back to hydraulic fracturing, however, is that it uses large volumes

Combined Dip‐Coating and Spray Coating Techniques for Modifying PVDF Membranes With PDMS and TiO2 for Photocatalytic Membrane Distillation

open access: yesJournal of Applied Polymer Science, EarlyView.
Main steps of membrane modification to impart hydrophobic character and its characterization for photocatalytic vacuum membrane distillation. ABSTRACT Membrane modification or functionalization techniques are widely studied to develop membranes with tailored properties for specific applications. This work investigates the combination of two methods—dip‐
