How water dissolves stone, molecule by molecule
Scientists have combined cutting-edge experimental techniques and computer simulations to find a new way of predicting how water dissolves crystalline structures like those found in natural stone and cement.
The promise of nanotechnology
If the promise of nanotechnology is to be fulfilled, then research programs must leapfrog to new nanomanufacturing processes. That''s the conclusion of a review of the current state of nanoscience and nanotechnology.
Optimizing carbon nanotube arrays for use in hot spots
Experimental evidence and computer simulations suggest how to grow structures with the best trade offs between three desired characteristics: strength, flexibility and the ability to dissipate heat.
Accelerated corrosion testing of silver provides clues about performance in atmospheric conditions
Gaining a deeper understanding of how environments containing humidity and ozone combined with sodium chloride surface contamination and ultraviolet illumination affect the corrosion rate of silver will enable researchers to create new models to better predict real-world atmospheric corrosion rates.
Flexible, stretchable fire-ant rafts
Fire-ant rafts aren't just unusual in that they're "viscoelastic," like Jell-O and toothpaste, according to a new study. Researchers found the rafts actively reorganize their structure, a feat that allows them to more effectively cushion themselves against applied forces, such as the battering of ra...
Research paves path for hybrid nano-materials to replace pills, human tissue
A team of researchers has uncovered critical information that could help scientists understand how protein polymers interact with other self-assembling biopolymers. The research helps explain naturally occurring nano-material within cells and could one day lead to engineered bio-composites for drug ...
New modelling technique could bypass the need for engineering prototypes
A new modelling technique has been developed that could eliminate the need to build costly prototypes, which are used to test engineering structures such as airplanes.
Building block for exoskeleton could lead to more independence among elderly
Researchers are studying human movement as they work on creating an exoskeleton to benefit elderly patients, stroke patients and paraplegics.
Fantastic phonons: Blocking sound, channeling heat with ''unprecedented precision''
The phonon, like the photon or electron, is a physical particle that travels like waves, representing mechanical vibration. Phonons transmit everyday sound and heat. Recent progress in phononics has led to the development of new ideas and devices that are using phononic properties to control sound a...
Controlling liquid crystals: Another tool in the directed assembly toolkitStories 1 - 10 of 495
Scientists have already developed a technique for controlling liquid crystals by means of physical templates and elastic energy, rather than the electromagnetic fields that manipulate them in televisions and computer monitors. They envision using this technique to direct the assembly of other materi...
