Daicel Chemical Industries, Ltd. and Groupe Novasep SAS, announce the formation of a strategic technical co-operation aimed at streamlining the use of chiral chromatography to manufacture late-stage clinical and commercial chiral intermediates and APIs. Under the terms of the agreement, the ...
Suitanes: mechanically interlocked molecules
An enormous challenge to science is the generation of two individual molecules that are not chemically bound to each other but are mechanically wedged together to form a tight link. A team of British and American researchers have now developed a whole new family of such mutually interlocked ...
Lawrence Livermore National Laboratory researchers have discovered that three is the magic number when it comes to strengthening metals. Since the Iron Age, metallurgists have known that metals such as steel become stronger and harder the more you hit (or beat) on them. But it wasn't always clear ...
Comparison of granular jets at atmospheric pressure and in a vacuum
University of Chicago physicists have created a novel state of matter using nothing more than a container of loosely packed sand and a falling marble. They have found that the impacting marble produces a jet of sand grains that briefly behaves like a special type of dense fluid. "We're ...
An experiment that began as a "fantasy pipe dream" just three years ago is now a reality. Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley, combining nanotechnology with biochemistry, have created unique synthetic membranes ...
New integrated architecture enables operators to plan, manage and optimize oil and gas asset production
Schlumberger Information Solutions (SIS) and Aspen Technology, Inc. announced that they have entered into a five-year alliance to provide the upstream oil and gas business with an advanced, real-time software solution. The solution will provide operators with a continuous view of their assets, ...
Fat goes rancid over time if no antioxidants are added. Our bodies also contain fat molecules, called lipids. They are essential for our cell membranes. These too must be protected from excessive peroxidation; left unchecked, it can cause atherosclerosis or various autoimmune and ...
caesar: Research for the market of tomorrow More than 2000 years ago the Romans founded Bonn - since 1999 caesar is again active there, but not as an emperor. Today, caesar stands for "center of advanced european studies and research" and as such achieves high quality research competing on the ...
Using a new production technology Schott Guinchard of Switzerland has been successful in speeding up the machining and polishing of high-precision aspherical lenses and further improving their quality. The precision of the new process is 0.1 - 0.6 µm PV with a surface roughness ...
