3D Concrete Printing of Triply Periodic Minimum Surfaces for Enhanced Carbon Capture and Storage

open access: yesAdvanced Functional Materials, EarlyView.
A 3D‐printable and carbon‐capturing concrete is developed by replacing cement with diatomaceous earth (DE), which enhances rheology, provides hierarchical porosity, and serves as a nucleation site for carbonation. Maximum absorption of 488.7 gCO2 kgcement−1 is achieved in 7 days, a 142% increase over conventional concrete, and the triply periodic ...

Towards FEA over Tangled Quads [PDF]

open access: yesProcedia Engineering, 2014
AbstractIn finite element analysis (FEA), a mesh is said to be tangled if it contains an element with negative Jacobian-determinant. Tangling can occur during mesh optimization and mesh morphing. Modern FEA unfortunately cannot handle such tangled meshes, i.e., it will lead to erroneous results.

Additively Manufactured 3D Auxetic Metamaterials for Structurally Guided Capacitive and Resistive Tactile Sensing

open access: yesAdvanced Functional Materials, EarlyView.
A 3D‐architected auxetic metamaterial is used to construct capacitive and resistive tactile sensors via digital light processing‐based additive manufacturing. The inward deformation of the proposed structure under compression amplifies local strain, enhancing sensing performance.

Crush Simulation of Cars with FEA [PDF]

open access: yesMechanical Engineering, 1998
This article illustrates that while crash analyses have been carried out with success, a crush analysis is much more difficult to achieve. In a crash analysis, the inertia effects smooth out the nonlinearities and deficiencies in the solution algorithms.

Anisotropic Shear Properties of Organic Interfaces in Bio‐composite Materials

open access: yesAdvanced Functional Materials, EarlyView.
A novel cantilever design enables direct probing of shear properties at single organic interfaces within biocomposite prismatic ultrastructures. By decoupling lateral and torsional shear responses, the method reveals isotropic behavior in Atrina vexillum and pronounced anisotropy in Unio pictorum.

Geometrically Templated, Ultra‐Lightweight and High Strength Soap Films from Lyotropic Liquid Crystalline Graphene Oxide/Polymer Composites

open access: yesAdvanced Functional Materials, EarlyView.
Shellular materials form spontaneously by dip coating the primitive triply periodic minimal surface (TPMS) wireframe in an aqueous solution of lyotropic liquid crystalline graphene oxide (GO) nanosheets mixed with polymers. Regulated by surface tension, GO nanosheets align on the polymer soap film as the stress builds up during drying.

O Processo de Offshoring Internacional Ocorre Apenas de Países Desenvolvidos para as Economias Emergentes?

open access: yesInternext: Revista Eletrônica de Negócios Internacionais, 2012
The offshoring business is booming and what was used by few US pioneers are now spreading through the world (Economist Intelligent Unit, 2006). It is a very new issue at least regarding the origin of the expression and related to services and, even a ...
