A strategic case for e-adoption in healthcare supply chains

A growing body of literature suggests that greater benefits of e-business will be obtained when e-business is integrated throughout a supply chain. However, organizations are still cautious in adopting e-business technologies. This paper examines whether a strategic case for e-commerce can be recognised and the factors that influence e-adoption, using e-business development models, a contingency approach and a stakeholder approach. The paper explores the link of e-commerce with strategy and the potential strategic benefits, risks and problems. This paper analysed e-adoption in four diverse healthcare supply chains in the context of the English National Health Service (NHS). The fieldwork showed there is of limited use of e- in supply chains; there are key problems associated with perceived benefits and costs by different actors both within organisations and within the chain. The paper proposes a framework to link the case for e-commerce with the achievement of strategic objectives across three inter-related domains—health, supply and business.

The performance of poly(styrene)-block-poly(2-vinyl pyridine)-block- poly(styrene) triblock copolymers as pH-driven actuators

Poly(styrene)-block-poly(2-vinyl pyridine)-block-poly(styrene) (PS-b-P2VP-b-PS) triblock copolymers were synthesised by anionic polymerisation. Thick films were cast from solution and their structure analysed by small angle X-ray scattering (SAXS). Longer annealing times led to more ordered structures whereas short evaporation times effectively "lock" the polymer chains in a disordered state by vitrification. Well-ordered structures not only provide an isotropic network, which reduces localised stress within the material, but are also essential for fundamental studies of soft matter because their activity on the molecular scale must be analysed and understood prior to their use in technological applications. Well-characterised PS-b-P2VP-b-PS materials have been coupled to a pH-oscillating reaction and their potential application as responsive actuators is discussed.

Selective oxidation of allylic alcohols over highly ordered Pd/meso-Al2 O3 catalysts

Highly ordered mesoporous alumina was prepared via evaporation induced self assembly and was impregnated to afford a family of Pd/meso-Al2O3 catalysts for the aerobic selective oxidation (selox) of allylic alcohols under mild reaction conditions. CO chemisorption and XPS identify the presence of highly dispersed (0.9–2 nm) nanoparticles comprising heavily oxidised PdO surfaces, evidencing a strong palladium-alumina interaction. Surface PdO is confirmed as the catalytically active phase responsible for allylic alcohol selox, with initial rates for Pd/meso-Al2O3 far exceeding those achievable for palladium over either amorphous alumina or mesoporous silica supports. Pd/meso-Al2O3 is exceptionally active for the atom efficient selox of diverse allylic alcohols, with activity inversely proportional to alcohol mass.
