“…The above concept is becoming one of the main goals of developing new techniques or improving current approaches. 2,3 Nanomaterials, especially one-dimensional (1D) nanostructures, have distinct properties and are of great importance in understanding fundamental concepts and fabricating nanodevices. [4][5][6] Scientists are touting these nanostructures to bring us a brand-new and fantastic world.…”

A Green Chemical Approach to the Synthesis of Tellurium Nanowires

2005

Starch, an economical and safe carbohydrate, has been found to be not only an effective reducing agent but also a new morphology-directing agent for the synthesis of tellurium nanowires using commercial H2TeO4 precursor. The obtained tellurium nanowires are of single-crystal in nature, with an average diameter of approximately 25 nm and length up to 10 microm. A possible synthetic mechanism involves the chain-shaped bioorganic molecule acting as a template for the one-dimensional growth of inorganic tellurium. The effects of different chain-shaped structures and concentrations of biomolecules on the nanowire morphology have been investigated and different one-dimensional structures, including thick rods, short nanowires, bunched nanowires, and assembled spikelet structures, have been fabricated. These experimental results have been found to be useful in substantiating the proposed synthetic mechanism.

“…Considering the fact that there is more than a million new chemical compounds reported each year and close to a thousand new ones being added to the commercial domain each year (besides over 70,000 already existing), without any required training in toxicology or environmental sciences for the doctoral chemists, it is clear that increasing ecological awareness regarding chemical life cycles would present a key component of 'greening' education in chemistry of the coming era [81]. The principles of 'green chemistry' [82][83][84] should be unavoidably considered as the basics for any synthetic and processing approaches in the chemistry of nanomaterials as well. In that sense, the immediate toxic effects of nanoparticles on biological creatures and the destructive potentials of disobeying nanobots may be regarded as only superficial and anthropomorphic threats, whereas long-term effects that in addition include the problems of ecological sustainability, high-tech economics, intellectual property, social equality and transfer of technologies, should be given a prime interest.…”

Nanomaterials are typically considered as solid physical structures that comprise grain boundaries at the resolution of less than 100 nanometers, whereby nanotechnologies are depicted as dealing with the design of various applications based on employing the former. Some of the essential features of nanomaterials and the scientific approaches to their investigation are discussed in the course of this work. The real reason for the current scientific and technological interest in the physical effects at nanoscale is linked with the historic trend of refinement of human knowledge and of the corresponding ability to manipulate with the structural patterns of the Universe. Interesting novel properties of nanomaterials are presented as resulting from the interplay between the surface properties and quantum effects at nanoscale. Examples of peculiar combination properties that materials can exhibit with the transition to nanosized form are mentioned, with a particular emphasis on the nanoscopic aggregates of water molecules. Specific challenges tied with the further growth of the field, including the prospectives of functional superstructuring, biomimicry, green chemistry, and the interdisciplinary approach to research, are eventually outlined.

“…Going forward, green chemistry must become an integral part of both the classroom and research. Echoing the participants of last year's summer school, 1 we assert that green chemistry should be integrated into the curriculum and research of all universities in all scientific areas, including chemistry and engineering. Researchers must use green principles every day, and stress that a sustainable civilization depends on all people.…”
