Morphogenic Growth 3D Printing
Advanced Materials, EarlyView.I additive manufacturing process exploits the spatial propagation of a polymerization reaction front to produce 3D polymer parts 10× faster and 1000× more energy efficient than the fastest stereolithography. In contrast with existing 3D printing, this morphogenic process is inspired by biological “growth and form” due to the self‐directed propagation ...

Simulations of an offshore wind farm using large eddy simulation and a torque-controlled actuator disc model [PDF]
, 2014 We present here a computational fluid dynamics (CFD) simulation of Lillgrund offshore wind farm, which is located in the Oresund Strait between Sweden and Denmark. The simulation combines a dynamic representation of wind turbines embedded within a Large-Eddy Simulation CFD solver, and uses hr-adaptive meshing to increase or decrease mesh resolution ...

Foundations for offshore wind turbines
Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2003 An important engineering challenge of today, and a vital one for the future, is to develop and harvest alternative sources of energy. This is a firm priority in the UK, with the government setting a target of 10% of electricity from renewable sources by 2010.

A Bio‐Inspired Perspective on Materials Sustainability
Advanced Materials, EarlyView.This perspective discusses natural materials as inspiration for sustainable engineering designs and the processing of materials. First, circularity, longevity, parsimony, and activity are presented as essential material paradigms. The perspective then uses many examples of natural and technical materials to introduce principles such as oligo ...
