Assessment of release and toxicity of NP from silicon-based polymer composites in a life cycle perspective

Irfan A., Sachse S., Njuguna J., Zhu H., Cranfield University, UK

Nanomaterial integration in public domain raises concerns regarding human health impact. This study examines the possibility of nanoparticle release from new engineered nanocomposites, using real life scenarios in life cycle analysis approach. Physical and biological [...]

Electrospun 5-fluorouracil loaded bovine serum albumin-polyvinylpyrrolidone nanofibers

Illangakoon U.E., Chatterton N.P., Williams G.R., Nazir T., London Metropolitan University, UK

5-FU loaded bovine serum albumin (BSA)/ polyvinylpyrrolidone (PVP) nanofibers prepared using an electrospinning process. The nanofibers were characterised by scanning electron microscopy (SEM) energy - dispersion spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction [...]

Combined targeted hyperthermia and drug delivery with magnetic nanoparticles

Mitrelias T., Tselepi M., Barnes C., Orel V., Schepotin I., Cavendish NanoTherapeutics, UK

Cancer remains the second leading cause of deaths worldwide and in the U.S. alone every year there are over 1.5 million new diagnoses. Technologies that would allow targeted destruction of tumours by localising the delivery [...]

Nanoscale SPM Characterisation of Nacre Argonite Plates and Synthetic Human Amyloid Fibres

Grishin I., Tinker C., Allsop D., Robson A., Kolosov O.V., Lancaster University, UK

Nacre exhibits structural robustness despite the brittle nature of its constituents. A detailed understanding of its fabrication principles developed in nature can lead to new ideas in material design and synthesis. But due to this [...]

Reliability Prediction of Single-Crystal Silicon MEMS Using Dynamic Raman Spectroscopy

Dewanto R., Hu Z., Gallacher B., Hedley J., Newcastle University, UK

This paper proposes an extension and improvement to reliability predictions in single-crystal silicon MEMS by utilizing dynamic Raman spectroscopy to allow the gathering process of Weibull fracture test data to be done directly on devices [...]

Novel Hierarchically Ordered Porous Vanado-Silicate Nanocomposites for the Application in Industrial Catalysis

Howard M., Whittle J., Zhang F., Zhao D., Sen T., University of Central Lancashire, UK

A novel hierarchically ordered porous vanado-silicate nanocompsoites were fabricated with isolated vanadium species with well dispersed state in the porous martrix for the oxidation of bulkier organic molecules i.e cyclooctene for the selective production of [...]

Morphology control of carbon nanotubes in continuously spun fibres

Sundaram R.M., Koziol K.K., Windle A.H., University of Cambridge, UK

Multifunctional attributes of carbon nanotubes (CNTs) have attracted the focus of industrial and academic communities alike. Translating the properties of individual CNTs into their macroscopic ensembles – fibres, yarns or films - is envisaged to [...]

Mapping nanomechanical phenomena of graphene nanostructures using force modulation and ultrasonic force microscopy

Kolosov O.V., Kay N.D., Robinson B.J., Rosamond M., Zeze D., Dinelli F., Lancaster University, UK

Whereas graphene electronic properties are extensively studied, mechanical properties of graphene nanostructures are much less experimentally explored even for simple graphene structures. We use a combination of force sensitive scanning probe microscopies that combines low [...]

Direct nanoscale imaging of ballistic and diffusive thermal transport in graphene nanostructures

Kolosov O.V., Pumarol M.E., Tovee P., Rosamond M.C., Petty M.C., Zeze D.A., Falko V., Lancaster University, UK

We report direct imaging of thermal transport in single and few-layer graphene with approximately 50 nm lateral resolution using high vacuum scanning thermal microscopy. Images reveal low thermal resistance of areas of suspended graphene where [...]

A Novel Electrical Contacting Technology to Graphene

Ghosh B., Dale C., Dewanto R., Keegan N., Hedley J., Newcastle University, UK

The paper reports on a Ni based electrical contacting technology to graphene that is simple and effective and can be adopted by laboratories lacking high grade infrastructure. The graphene surface is masked, activated and then [...]
