Wood-derived foam materials
Since most foam materials are made of petrochemical plastics, they aren't very climate-friendly. But now an alternative is in sight - a novel foam material produced entirely from wood, which is not harmful to the environment and is also recyclable. In the long term, wood foam could replace conventio...
Revolutionary discovery leads to invention of new ''building blocks''
Taking a revolutionary ''building blocks'' approach, a research team has invented a new thinking pathway in the design and synthesis of macromolecules by creating an original class of giant tetrahedra. Through a reaction called ''click chemistry,'' these tetrahedron building blocks can then be preci...
Four-dimensional printing unfolding as technology that takes 3D printing to an entirely new level
The fourth dimension is time, shape shifting in fact, and scientists are already working on the next revolution in additive manufacturing.
Insects inspire next generation of hearing aids
An insect-inspired microphone that can tackle the problem of locating sounds and eliminate background noise is set to revolutionize modern-day hearing aid systems, scientists say. Despite remarkable advances in sound analysis in hearing aids, the actual microphone itself has remained essentially unc...
Understanding thermo-mechanical properties of a new class of materials
Scientists describe how an accurate statistical description of heterogeneous particulate materials, which is used within statistical micromechanics theories, governs the overall thermo-mechanical properties.
New software analyses the effect of climate change on buildings from the cloud
Construction companies have begun to use a simulation software which analyses for the first time the entire life cycle of a building, from creation to deconstruction. The tool, which can be used in the cloud, includes aspects such as energy consumption, materials and social repercussions. It also al...
Plant oils used for novel bio-based plastics
Researchers have developed a new way to use plant oils like olive and linseed oil to create polyurethane, a plastic material used in everything from foam insulation panels to tires, hoses and sealants.
Engineers now understand how complex carbon nanostructures form
Carbon nanotubes (CNTs) are microscopic tubular structures that engineers ''grow'' through a process conducted in a high-temperature furnace. The forces that create the CNT structures known as ''forests'' often are unpredictable and are mostly left to chance. Now, a researcher has developed a way to...
Carbon nanotube computing?
Scientists are using single-walled carbon nanotube composites (SWCNTs) as a material in "unconventional" computing. By studying the mechanical and electrical properties of the materials, they discovered a correlation between SWCNT concentration/viscosity/conductivity and the computational capability...
Wobbly no more: Work on analogical processing helps children learn key engineering principleStories 1 - 10 of 154
Children love to build things. Often half the fun for them is building something and then knocking it down. But in a new study children had just as much fun learning how to keep their masterpieces upright -- they learned a key elementary engineering principle.
