During the conversion of light into electricity, such as in solar cells, a large part of the input light energy is lost. This is due to the behaviour of electrons inside of materials. If light hits a material, it stimulates electrons energetically for a fraction of a second, before they pass the ene more
Researchers at Chalmers University of Technology, Sweden, have developed a graphene assembled film that has over 60 percent higher thermal conductivity than graphite film – despite the fact that graphite simply consists of many layers of graphene. The graphene film shows great potential as a novel h more
An international research team led by scientists at Beihang University in China and The University of Texas at Dallas has developed high-strength, super-tough sheets of carbon that can be inexpensively fabricated at low temperatures. The team made the sheets by chemically stitching together platelet more
As demonstrated here, there are a broad range of HPLC applications used in development, production, validation and release of protein therapeutics for human use. Some of the applications mentioned above are mandatory when submitting a new biopharmace more
You may not have been aware, but this week is Graphene Week 2015, which marks a yearly week-long conference at the University of Manchester based around the emerging science and technological applications of graphene. This seemed as good a time as any to take a look at graphene: what it is, why some more
In this month’s Periodic Graphics in C&EN, we’re looking at the chemistry behind the recent news stories of lithium-ion batteries in some devices catching fire. You can see the full graphic over on the C&EN site. Also, for more lithium battery chemistry, head over to the recent RealTimeChem Week gra more
Today’s graphic takes a look at the research of Kent Griffith (@kentjgriffith), a PhD student from the University of Cambridge who’s currently looking into developing advanced lithium ion batteries to power our phones, laptops, and more. more
Spectroscopic and nanoscale imaging investigations concerning the spatial extent of molecular orbitals at organic/substrate interfaces have been of intense interest to understand charge dynamics. Here, the spatial extent of unoccupied molecular orbitals of ultrathin rubrene [5,6,11,12-tetraphenyltet more

With the technological progress and market expansion, the production capacity and output of hydrofluoric acid have been growing rapidly. By the end of 2008, China's actual annual production capacity of hydrofluoric acid hit more than one million tons. However, hydrofluoric acid, especially high-puri more
