Genes Translocated into the Plastid Inverted Repeat Show Decelerated Substitution Rates and Elevated GC Content. [PDF]

open access: yes, 2016
Plant chloroplast genomes (plastomes) are characterized by an inverted repeat (IR) region and two larger single copy (SC) regions. Patterns of molecular evolution in the IR and SC regions differ, most notably by a reduced rate of nucleotide substitution ...

Methods of Parallel Voxel Manipulation for 3D Digital Printing [PDF]

open access: yes, 2007
A novel digital printing concept is explored for desktop fabrication of multimaterial objects with arbitrary 3D geometry. Digital objects are composed of many discrete, self-aligning voxels instead of continuous (analog) deposition techniques.

Electroless plating of NiP and Cu on polylactic acid and polyethylene terephthalate glycol-modified for 3D printed flexible substrates [PDF]

open access: yes, 2016
Electroless nickel and copper metallization of 3Dprinted polymers like polylactic acid and polyethylene terephthalate glycol modified is presented. The plating process is tested on suitable samples, which reproduce the characteristic morphologies used in

Evaluation of thermoplastic composites for the manufacture of H-Darrieus wind Turbine blades on a laboratory scale

open access: yesJournal of Materials Research and Technology
Wind energy is one of the most widely produced sources of renewable and clean electricity. However, the blades of wind turbines pose a significant environmental challenge due to the difficulty in recycling them. To address this issue, research is focused
