Being developed by a consortium of UK universities, the nanostructures can regulate reactions, momentum, and heat and mass transfer inside chemical reactors. This technology will provide a step change in reactor technology for the chemical, pharmaceutical and agrochemical industries.
Professor Yulong Ding of the Institute of Particle Science and Engineering at the University of Leeds explains: “This research programme is an important step towards producing the next generation of smart “small footprint”, greener reactors. The responsive reaction systems we are investigating could make the measurement systems currently used in reactors redundant.”
The technique is being developed through a collaborative research programme initiated by Professor Ding together with Dr Alexei Lapkin at the University of Bath, and Professor Lee Cronin at the University of Glasgow.
The programme involves designing and producing molecular metal oxides and polymers as building blocks, and engineering those blocks to form nanoscale structures, which are responsive to internal and / or external stimuli such as pH, heat or light. The structures can be dispersed in fluid, or coated on the reactor walls.
As conditions inside the reactor change, the nanostructured particles will respond by changing their size, shape, or structure. These changes could in turn alter transport properties such as thermal conductivity and viscosity, and catalyst activity – and hence regulate the reactions.
Professor Ding also believes that these systems also have the potential to eliminate the risk of ‘runaway’, where a chemical reaction goes out of control.
The three-year programme, funded by the Engineering and Physical Sciences Research Council (EPSRC), brings together leading experts in the fields of Chemistry, Chemical Engineering and Particle Science & Engineering.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
