Alkaloids are natural nitrogen-containing compounds produced by plants and microbes. These molecules, such as morphine and quinine, are important human medicines. Alkaloids are typically polycyclic in nature. While the polycyclic characteristics are important for their bioactivities, these ... more
When John Crocker, a professor of chemical and biomolecular engineering in the University of Pennsylvania's School of Engineering and Applied Science was a graduate student, his advisor gathered together everyone in his lab to "throw down the gauntlet" on a new challenge in the field.
Someo ... more
Because the sun doesn't always shine, solar utilities need a way to store extra charge for a rainy day. The same goes for wind power facilities, since the wind doesn't always blow. To take full advantage of renewable energy, electrical grids need large batteries that can store the power com ... more
Researchers have created a high performance anode material for lithium-ion batteries (LIBs) using waste silicon (Si) sawdust.
It is energy-consuming and expensive to produce Si wafers with high purity (> 99.99%). On top of that, some 50% of Si is actually discarded as industrial waste in th ... more
For the first time ever, scientists have captured images of terahertz electron dynamics of a semiconductor surface on the atomic scale. The successful experiment indicates a bright future for the new and quickly growing sub-field called terahertz scanning tunneling microscopy (THz-STM), pio ... more
Rainer Lehmann appointed to the Executive Board
The Supervisory Board of Sartorius AG approved the Executive Board’s recommendation to submit a proposal to the Annual Shareholders’ Meeting on April 6, 2017, to raise dividends to 0.46 euros per preference share and to 0.45 per ordinary share. Prior-year dividends, adjusted by the stock sp ... more
In 2015 UC Santa Barbara mechanical engineer and materials scientist Jonathan Berger developed an idea that could change the way people think about high-performance structural materials. Two years later, his concept is paying research dividends.
In a letter published in the journal Nature, ... more
Petrochemical industry looks for ideas
World leading companies in the field of gas processing, petrochemicals and chemicals join efforts to promote the innovative development of the industry. Chemical engineering startups can apply until March 1, 2017 for the IQ-CHem contest supported by SIBUR, The Dow Chemical Company, DuPont, ... more
The Semiconductor Industry Association has estimated that at current rates of increase, computers’ energy requirements will exceed the world’s total power output by 2040.
Using light rather than electricity to move data would dramatically reduce computer chips’ energy consumption, and the p ... more
Researchers measured the electronic structure of stacks of 2D 'wonder' materials
Dr Neil Wilson in the Department of Physics has developed a new technique to measure the electronic structures of stacks of two-dimensional materials -- flat, atomically thin, highly conductive, and extremely strong materials - for the first time.
Multiple stacked layers of 2D materials -- ... more
