Chemists journey to Gobi region for samples, discover novel dye in textiles from Peru
Although searching for 3,000-year-old mummy textiles in tombs under the blazing sun of a western Chinese desert may seem more Indiana Jones than analytical chemist, two Boston University researchers recently did just that. Traveling along the ancient Silk Road in Xinjiang Province on their quest, they found the ancient fabrics – and hit upon a research adventure that combined chemistry, archaeology, anthropology, botany, and art.
The chemists, Richard Laursen, a professor in the Boston University Department of Chemistry, and Xian Zhang, a chemistry graduate student, have refined a technique that helps archaeologists and anthropologists identify the plant species that ancient people used to make fabric dyes. Their technique has not only provided researchers with a new, more powerful tool for analyzing previously known dye types, it also has led to the discovery of at least one never-before described dye. In addition, the BU chemists have started a catalogue of plant sample characteristics for use by dye researchers around the world.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
