Robot Speeds Up Glass Development
2011-11-15 04:37:00

Model by model, the electronics in a car are being moved closer to the engine block. This is why the materials used for the electronics must resist increasing heat — so the glass solder being used as glue must be continually optimized. For the first time ever, a robot takes on the task of developing new types of glass and examining their characteristics. Researchers will introduce this robot at the “productronica“ trade fair to be held in Munich, Germany, from November 15 -...

Chemical engineer Ms Inês Mariz has presented guidelines for obtaining better quality and more efficient latex, in a PhD thesis defended at the University of the Basque Country (UPV/EHU). This involves a strategy which facilitates obtaining a more concentrated material without it losing its handling properties. In this way it is able to cover the substrate in question with fewer layers than is usual, it dries quicker, its formulation is more flexible and enables savings in...

In things thick and thin: Cornell physicists explain how fluids — such as paint or paste - behave by observing how micron-sized suspended particles dance in real time. Using high-speed microscopy, the scientists unveil how these particles are responding to fluid flows from shear — a specific way of stirring. (Science, Sept. 2). Observations by Xiang Cheng, Cornell post-doctoral researcher in physics and Itai Cohen, Cornell associate professor of physics, are the first to link...

A liquid does not have to be a disordered bunch of particles: A team of researchers at Vienna University of Technology (TU Vienna) and the University of Vienna has discovered intriguing structures formed by tiny particles floating in liquids. Under mechanical strain, particle clusters in liquids can spontaneously form strings and dramatically alter the properties of the liquid. What is common to blood, ink and gruel? They are all liquids in which tiny particles are suspended "“ so...

New 3-D-nanostructured chip offers a litmus test for surface tension (and doubles as a carrier for secret messages) Materials scientists and applied physicists collaborating at Harvard's School of Engineering and Applied Sciences (SEAS) have invented a new device that can instantly identify an unknown liquid. The device, which fits in the palm of a hand and requires no power source, exploits the chemical and optical properties of precisely nanostructured materials to distinguish liquids by...

According to a multidisciplinary team of researchers, American artist Jackson Pollock's paintings do not defy the laws of physics. The researchers from Boston College and Harvard believe Pollock was an intuitive master of laws that govern the flow of liquids under gravity. "In order to understand what is taking place with Pollock, it's essential to understand the laws of physics and the dynamics at play under the laws of gravity," Claude Cernuschi, a professor of art history at Boston...

Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
