Advanced Materials, EarlyView.Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Determination of the fracture resistance of polymer gels via cutting with wire
, 2009 In this work, the applicability of wire cutting in determining the fracture resistance of poly-acrylamide (p-AA) hydrogels with different cross-link densities was investigated. From the results obtained in cutting tests with wires of different diameters,

The effect of cemented natural fractures on hydraulic fracture propagation
, 2017 Microseismic events, which are generated during hydraulic fracturing treatments, suggest that a complicated fracture network develops in many naturally−fractured unconventional reservoirs. Deformation along weak planes, such as cemented natural fractures,

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics
Advanced Materials, EarlyView.“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Influence of stress sensitive differences on natural well productivity in fractured reservoirs
Youqicang pingjia yu kaifa, 2019 In order to study the productivity characteristics of low permeability reservoirs with natural fractures, we established a prediction model of natural fractured reservoir productivity considering stress sensitivity differences between matrix and natural ...

Hydraulic Fracturing in Formations with Permeable Natural Fractures
, 2013 The recently developed Unconventional Fracture Model (UFM*) simulates complex hydraulic fracture network propagation in a formation with pre-existing closed natural fractures, and explicitly models hydraulic injection into a fracture network with multiple propagating branches [1].

Characterisation of the 2D and 3D density and connectivity attributes of fracture systems in carbonate reservoir analogues: implications for fluid flow [PDF]
, 2013 Fault zones, hosted in fractured carbonate reservoirs, can behave as either high porosity and permeability conduits, favoring the migration of fluids; or, conversely, as low porosity and permeability barriers, retarding fluid flow, due to the presence of
