FIZ Karlsruhe announces that the complete ReaxysFile™ is now available on STN®

Full depth of Reaxys’ experimentally validated chemical substance data, reactions and associated properties is now available to information professionals via STN, the search tool for precision searching and comprehensive, high-quality coverage of science and intellectual property information.

FIZ Karlsruhe – Leibniz Institute for Information Infrastructure has launched a significantly updated version of ReaxysFileTM on STN InternationalSM, the renowned online service for research and patent information. ReaxysFile now contains the full content from Reaxys®, a leading source for chemical substance and reaction data produced by Elsevier.

Information on several million substances has been added, including inorganic substances and substances derived from patents, bringing the database to the same content level as in Reaxys. This will immediately increase information professionals’ and patent experts’ efficiency when investigating new research opportunities, performing freedom-to-operate searches or looking for reliable chemical substance information. ReaxysFile can also be used to retrieve relevant information for meeting regulatory requirements on chemicals, e.g. REACH.

ReaxysFile is a major factual database containing fully searchable chemical structures and reactions, associated with a depth of chemical and physical properties – all experimentally measured. With historical data dating back to 1771 and the most relevant current publications (journals and patents) in organic, inorganic and organometallic chemistry, ReaxysFile forms a valuable part of STN for information professionals and patent experts looking either for pin-point accuracy concerning a particular substance, or whilst searching for broader research questions.

“We are pleased to see the collaboration with Elsevier further extended by this successful update to the ReaxysFile,” says Rainer Stuike-Prill, Vice President Marketing & Sales at FIZ Karlsruhe. “Reaxys is widely acknowledged as a valuable source for a detailed view of chemistry data. With the addition of the full version of ReaxysFile to STN users benefit from more comprehensive and precise search results.”

Reaxys® and the Reaxys® trademark are owned and protected by Reed Elsevier Properties SA.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

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...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

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.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

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...

Im Focus: New Products - Highlights of COMPAMED 2016

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...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
