Sulfated Carbon Quantum Dots as Efficient Visible-Light Switchable Acid Catalysts for Room-Temperature Ring-Opening Reactions
H. Li, C. Sun, M. Ali, F. Zhou, X. Zhang and D. R. MacFarlane
Angewandte Chemie International Edition, DOI: 10.1002/anie.201501698

We have developed a novel, photo-switchable solid-acid catalyst based on carbon quantum dots (CQDs). The CQDs are decorated with small amounts of hydrogensulfate groups, which gives the CQDs an acidity that we've shown can be easily turned on or off using light. These sulphated CQDs have been shown to be a highly efficient acid catalyst in reactions such as the ring opening of epoxides with methanol and other primary alcohols. The catalyst is easily separated from the reaction medium by filtration, and we have demonstrated they can retain their functionality with multiple cycles of reuse.

We thoroughly investigated the biological, structural and chemical stability of epidermal growth factor receptor monoclonal antibody (EGFR mAb) using choline-based buffered ionic liquids (BILs). The results demonstrated substantially enhanced stabilities in our BILs, indicating their huge promise as real-world green biological buffers for antibody storage and transportation.

Novel imidazolinium ionic liquids and organic salts

Electrochimica Acta, 2015, Volume 159, Pages 219–226

We have prepared a novel family of ionic liquids and organic salts based on the imidazolinium cation. Their physical properties are compared with their imidazolium analogues, as well as anti-corrosion performance. The properties of the imidazolinium salts outperformed their imidazolium analogues in several cases, which  interestingly depended on the anion used. The electrochemical window of the imidazolinium was slightly extended in the reductive direction, due to the lower proton activity produced by the cation in this case. 

Flagellar filament bio-templated inorganic oxide materials - towards an efficient lithium battery anode
S.N Beznosov, P.S. Veluri, M.G. Pyatibratov, A. Chatterjee, D.R. MacFarlane, O.V. Fedorov and S. Mitra
Scientific Reports, 5, Article number: 7736; DOI:10.1038/srep07736

We use genetically modified flagellar filaments as nanosized structural templates to build a new generation of energy-intensive and sustainable electrode materials for batteries. The use of biomaterials as a nanosized structural template for these materials has the potential to produce hitherto unachievable structures.

Porus Nitrogen-Doped Carbon Microspheres Derived from Microporous Polymeric Organic Frameworks for High Performance Electric Double-Layer Capacitors

This research presents a simple and efficient method to synthesize porous nitrogen-doped carbon microspheres (PNCM) by the carbonization of microporous organic polymer frameworks. The KOH activiation process was used to tune the porous texture of the PNCM and produce an activated PNCM (A-PNCM). As electrode materials for supercapacitors, the PNCM and A-PNCM exhibit high specific capacitance, excellent rate performance, and long-term cycling stability. These properties are attributed to the highly developed porous structure, large specific surface area, and nitrogen doping.
