The goals of alternative technology are to decrease demand for critical elements by ensuring a secure supply of technology that is environmentally friendly, increased efficiency with lower costs, and with more common materials to avoid potential future materials crises. [3] Alternative technologies use renewable energy sources such as solar ...
Alternative natural materials are natural materials like rock or adobe that are not as commonly used as materials such as wood or iron. Alternative natural materials have many practical uses in areas such as sustainable architecture and engineering. The main purpose of using such materials is to minimize the negative effects that built ...
The criteria for this list is that the technology must: Exist in some way; purely hypothetical technologies cannot be considered emerging and should be covered in the list of hypothetical technologies instead. However, technologies being actively researched and prototyped are acceptable. Have a Wikipedia article or adjacent citation covering them.
Non-carbon nanotubes are an alternative material to better-explored carbon nanotubes, showing advantages such as easy synthetic access and high crystallinity, [16] good uniformity and dispersion, predefined electrical conductivity depending on the composition of the starting material and needle-like morphology, good adhesion to a number of polymers and high impact-resistance. [17]
This is the dominant technology currently used in most solar PV systems. Most thin-film solar cells are classified as second generation, made using thin layers of well-studied materials like amorphous silicon (a-Si), cadmium telluride (CdTe), copper indium gallium selenide (CIGS), or gallium arsenide (GaAs).
Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter.
Bioplastics offer a sustainable and versatile alternative to traditional construction materials, with significant environmental and economic benefits. While challenges remain, particularly in terms of cost and performance, the ongoing advancements in bioplastic technology [ 82 ] hold the potential to transform the construction industry and ...
As such, recent efforts to toughen CFRPs include modifying the existing epoxy material and finding alternative polymer matrix. One such material with high promise is PEEK, which exhibits an order of magnitude greater toughness with similar elastic modulus and tensile strength. [8] However, PEEK is much more difficult to process and more ...
