An error diffusion based method to generate functionally graded cellular structures (2014)
Journal Article

The spatial variation of cell size in a functionally graded cellular structure is achieved using error diffusion to convert a continuous tone image into binary form. Effects of two control parameters, greyscale value and resolution on the resulting c... Read More about An error diffusion based method to generate functionally graded cellular structures.

Combining mercury thermoporometry with integrated gas sorption and mercury porosimetry to improve accuracy of pore-size distributions for disordered solids (2014)
Journal Article

The typical approach to analysing raw data, from common pore characterization methods such as gas sorption and mercury porosimetry, to obtain pore size distributions for disordered porous solids generally makes several critical assumptions that impac...

Experimental study of mercury removal from exhaust gases (2014)
Journal Article

An initial study has been made of the use of synthetic zeolites for mercury capture from exhaust gases. Synthetic zeolites (Na-X and Na-P1), and for comparison a natural zeolite (clinoptilolite) and activated carbon with bromine (AC/Br) were tested f...

Enhanced ‘in situ’ catalysis via microwave selective heating: catalytic chain transfer polymerisation (2014)
Journal Article

An extremely facile, single stage, ‘in-situ’, Catalytic Chain Transfer Polymerisation (CCTP) process has been identified, where the optimal polymerisation process was shown to depend upon a combination of catalyst characteristics (i.e. solubility, se...

Facile one-spot synthesis of highly branched polycaprolactone (2014)
Journal Article

Reported is the first solvent-free (bulk) synthesis of degradable/bioresorbable, highly branched polymers via tin octanoate Sn(Oct2) catalysed controlled ring opening co-polymerisation (ROP) of mono and di-functional lactone monomers that proceed to...

The rapid size- and shape-controlled continuous hydrothermal synthesis of metal sulphide nanomaterials (2014)
Journal Article

Continuous flow hydrothermal synthesis offers a cheap, green and highly scalable route for the preparation of inorganic nanomaterials which has predominantly been applied to metal oxide based materials. In this work we report the first continuous flo... Read More about The rapid size- and shape-controlled continuous hydrothermal synthesis of metal sulphide nanomaterials.

Differential spontaneous folding of mycolic acids from Mycobacterium tuberculosis (2013)
Journal Article

Experimental study of the hydrodynamic behaviour of slug flow in a vertical riser (2013)
Journal Article

This paper presents an investigation of the hydrodynamics of slug flow in a vertical 67 mm internal diameter riser. The slug flow regime was generated using a multiphase air–silicone oil mixture over a range of gas (0.42

UPLC-MS profiling of low molecular weight phlorotannin polymers in Ascophyllum nodosum, Helvetia canaliculata and Fucus spiralis (2013)
Journal Article

Phlorotannins are a group of complex polymers, found in particular brown macroalgae, composed solely of the monomer phloroglucinol (1,3,5-trihydroxybenzene). Their structural complexity arises from the number of possible linkage positions between eac...

Optimisation of biomass milling for conveyance and combustion (2013)
Conference Proceeding

Agricultural wastes are increasingly being used as biomass materials for co-firing in coal fired power stations. However issues in milling and conveyance of agricultural residues are limiting the use of these resources and a greater understanding of...

The impact of impurities in various crude A. annua extracts on the analysis of artemisinin by liquid chromatographic methods (2012)
Journal Article

Analysis of Artemisia annua extracts by liquid chromatographic methods has traditionally been complicated by the presence of significant quantities of impurities. It has been observed that these impurities often remain as a solid residue after sample...

Fault propagation modelling for fluid system health monitoring (2011)
Journal Article

Fault diagnostics systems are incorporated to determine the health of the system they monitor. There are however times when the diagnostics system reports faults which do not exist. This situation commonly arises at system start-up when high vibrat... Read More about Fault propagation modelling for fluid system health monitoring.

An efficient real-time method of analysis for non-coherent fault trees (2009)
Journal Article

Fault tree analysis is commonly used to assess the reliability of potentially hazardous industrial systems. The type of logic is usually restricted to AND and OR gates which makes the fault tree structure coherent. In non-coherent structures not only...

Qualitative analysis of complex modularized fault trees using binary decision diagrams (2006)
Journal Article

Fault tree analysis is commonly used in the reliability assessment of industrial systems. When complex systems are studied conventional methods can become computationally intensive and require the use of approximations. This leads to inaccuracies in...

Identification of typical eco-hydrological behaviours using InSAR allows landscape-scale mapping of peatland condition
Working Paper

Better tools for rapid and reliable assessment of global peatland extent and condition are urgently needed to support action to prevent their further decline. Peatland surface motion is a response to changes in the water and gas content of a peat bod...

Efficiency evaluation of a novel supercapattery stack with a power electronic interface for energy storage systems
Conference Proceeding

The increase of renewable energy generation seen as the only way to ensure clean and sustainable development, is under scrutiny due to its intermittent nature and an insufficient development of com-plementary technologies such as electrical energy st...
