Although naturally occurring biogenic and anthropogenic nanosized particles abound in nature, engineered QDs differ because of unique physicochemical properties that result from a combination of their crystalline metalloid core structure/composition and quantum-size confinement, which occurs when metal and semiconductor particles (QD cores) are smaller than their Bohr radii (~ 1 5 nm).
Not content with adopting the forms of nature, engineers are looking to adapt the processes of nature to design.
Where problems are technological in nature, engineers are needed to design and deliver the novel and effective solutions, hence the need for engineering creativity.
The Institute's sports teams are called the Engineers, their mascot since 1914 being a beaver, "nature's engineer".
Established in 1919, the Caltech Beavers (so named after "nature's engineer") cull players from one of the most rigorously selective, academically demanding universities in the world.
Agrobacterium tumefaciens, a soil-born phytopathogenic bacterium, is well known as a nature's engineer due to its ability to genetically transform the host by transferring a DNA fragment (called T-DNA) from its Ti plasmid to host-cell genome.
Ecological engineering is well suited to stream management because the self-organization process it uses fills some of the voids in current knowledge of stream ecosystems by using nature to engineer aspects of the ecosystem that humans cannot.
The business orientation of engineer-to-order companies is customer-centric due to the nature of engineer-to-order products, which are tailored and customized according to the specific requirements of each customer.
In engineered consortia, the external environment provides levers of control for microbes repurposed from nature or engineered to interact through synthetic biology.
Taylor, however, points out that the conservative nature of engineers lends them to stick with construction practices that have been in place for decades.
But just where tourists and villagers delight in nature, hydropower engineers and economists have long been frustrated; in such torrents they see an opportunity that for too long has been allowed to drain away.Himalayan rivers, fed by glacial meltwater and monsoon rain, offer an immense resource.
