Rice University researchers surprised to see twin-induced brittle-like fractures in gold nanowires Thin gold wires often used in high-end electronic applications are wonderfully flexible as well as conductive. But those qualities don't necessarily apply to the same wires at the nanoscale. A new study from Rice University finds gold wires less than 20 nanometers wide can become "brittle-like" under stress. It appears in the journal Advanced Functional Materials. The paper by Rice...

Hohai University in Nanjing has established a research tradition in hydraulic engineering over the last 95 years. During this time, Hohai has become a first class institution of higher education that focuses on a wide range of engineering subjects including civil engineering and water resources, which are of particular interest. China's hydropower development occurs mainly in the high mountains and canyons of the Qinghai-Tibet plateau in the southwestern provinces. Because of long term...

A variety of structural phenomena in exotic short-lived nuclei far from stability, especially in systems close to the particle drip lines, challenge model descriptions based on the self-consistent mean-field approximation. Because the Fermi level in a drip-line nucleus is very close to the continuum, both weakly-bound states and low-lying positive energy single-particle resonant states are essential to determine the ground state properties of such systems. The research team at Peking...

Materials scientists have known that a metal's strength (or weakness) is governed by dislocation interactions, a messy exchange of intersecting fault lines that move or ripple within metallic crystals. But what happens when metals are engineered at the nanoscale? Is there a way to make metals stronger and more ductile by manipulating their nanostructures? Brown University scientists may have figured out a way. In a paper published in Nature, Huajian Gao and researchers from the University of...

Johns Hopkins researchers have discovered that, under the right conditions, newly developed nanocrystalline materials exhibit surprising activity in the tiny spaces between the geometric clusters of atoms called nanocrystals from which they are made. This finding, detailed recently in the journal Science, is important because these nanomaterials are becoming more ubiquitous in the fabrication of microdevices and integrated circuits. Movement in the atomic realm can affect the mechanical...

Researchers at the California Institute of Technology (Caltech) have developed a way to make some notoriously brittle materials ductile"”yet stronger than ever"”simply by reducing their size. The work, by Dongchan Jang, senior postdoctoral scholar, and Julia R. Greer, assistant professor of materials science and mechanics at Caltech, could eventually lead to the development of innovative, superstrong, yet light and damage-tolerant materials. These new materials could be used as...

DAVIS, Calif., Jan. 22 /PRNewswire/ -- An elite panel of leading water, engineering, and environmental scientists from throughout the nation is set to meet for five days starting Sunday at the University of California at Davis to begin examining rules adopted by federal environmental and wildlife regulators to protect imperiled Delta fish species. The panel was put together by the National Academy of Sciences; the nation's most esteemed science body. U.S. Senator Dianne Feinstein,...

By stretching a foam ribbon and dissecting leaves, a mathematical model emerges Applied mathematicians dissected the morphology of the plantain lily (Hosta lancifolia), a characteristic long leaf with a saddle-like arc midsection and closely packed ripples along the edges. The simple cause of the lily's fan-like shape"”elastic relaxation resulting from bending during differential growth"”was revealed by using an equally simple technique, stretching foam ribbons. Haiyi Liang, a...

Word of the Day
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
