Improved synthesis of commercially valuable opiates : development of reactions for industrial applications

Describes the synthesis of thebaine and noroxymorphone - key intermediates in the synthesis of opiate drugs. The design and optimisation of these synthetic pathways were developed keeping in mind the concerns of industry.

Industrial and economic development : a holistic study of Brunei Darussalam

The primary objective of this research is to provide a framework for industrial and economic development with respect to Brunei Darussalam. The study is both novel and unique as it is potentially the most comprehensive holistic study performed to date with respect to industrial and economic development in Brunei.

Evaluation of cold forming lubricants for fastener manufacturing

Investigates the significance and interactive effects of lubricant type, workpiece surface texture and deformation rate under bulk metal, deformation conditions. A novel test rig was developed in conjunction with statistical test techniques. The result of this work identified a cold forming lubrication system with potential economic and environmental advantages over traditional lubrication systems.

Phosphonium ionic liquids as lubricants for aluminium-steel

The performance of a series of novel room temperature ionic liquids (ILs) based on the trihexyl(tetradecyl)phosphoniumcation (P66614 +) and a number of novel anions have been studied in pin-on-disk tests using a 100Cr6 steel ball on AA2024 aluminium disks.

The anions coupled to the (P66614 +) cation include diphenyl phosphate (DPP-), dibutyl phosphate (DBP-), bis (2,4,4-trimethyl pentyl) phosphinate (M3PPh-) and bis(2-ethyl hexyl) phosphate (BEH-).

More traditional anions such as bis(trifluoromethanesulfonyl) amide (NTf2 -) and bromide (Br-) were also investigated. Experiments were conducted at various loads to assess the IL film forming abilities.

The results suggest that the structure of the anion is important in forming a surface film that reduces the friction and wear of the aluminium disk. At 30N five of the six ILs tested showed a 30-90% reduction in wear, as determined from wear scar depth measurements, compared to fully formulated diesel oil.

The IL lubricant with a diphenyl phosphate anion achieved the lowest wear coefficient, showing a better performance than a typical fluorine-containing IL anion, NTf2.

To further investigate wear mechanisms and surface interactions the wear scars were analysed using a scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS).

Transition in wear performance for ionic liquid lubricants under increasing load

The effect of ionic liquid (IL) lubrication for aluminium/steel systems is highly dependant on the applied load and the IL structure. This study illustrates that a change in anion of an IL lubricant results in different physicochemical properties that will alter its performance at a given load. As the load is increased there is a shift in lubricant performance and mechanism of the IL. Up to a load of 30 N the lowest wear coefficient was achieved by a phosphonium diphenylphosphate IL, whilst above 30 N a phosphonium bis(trifluoromethanesulfonyl)amide IL was able to form a more tenacious tribolayer that resulted in the lowest wear.

TQM and labour productivity in Jordanian industrial companies

Reports on research to determine the degree of application of total quality management (TQM) philosophy and practices in industrial corporations in Jordan. Uses primary and secondary empirical data to examine the link between TQM and labour productivity. Survey responses were classified into two groups: high-TQM implementation and low-TQM implementation. Found that mean labour productivity measurements for high-TQM companies were significantly higher than for low-TQM companies over the period 1993-1998. Also, mean growth rates of labour productivity measurements for companies with high-level TQM were higher than for those with low-level TQM during this period. Regression analysis demonstrated a statistically significant positive relationship between TQM and labour productivity.

Industrial biotechnology for the production of proteins/enzymes for a sustainable future

Worldwide emergence of Industrial biotechnology (IB) is providing opportunities to produce enzymes/proteins with variety of industrial/therapeutic applications. In transitioning the Australian economy towards a sustainable future, Federal government identified the development of IB pathway which would ensure increased productivity, enhanced sustainability, health, safety and reduced environmental footprint. The presentation will revolve around specific stories that drives Deakin University newest technology platform which applies biology and fermentation in an integrated way to play a crucial role in developing cost-effective technologies for the development of molecules that can benefit pharmaceutical and food industry in regional Victoria and Australia in general. The talk will also highlight specific examples where new products like recombinant rhamnosidase (an enzyme used for the production of flavonoids with health benefits) and ribosome inactivating proteins (detected in medicinal plants which possess RNA N- glycosidase activity that depurinates the major rRNA, thus damaging ribosome in an irreversible manner and arresting protein synthesis) would be made available through bioprocessing.
