An epitaxial 200 nm thick film of Pb(Zr0.40Ti0.60)O-3 (PZT) has been deposited by reactive rf magnetron sputtering on conductive Nb-doped SrTiO3 (100) (STO). The patterning process involved electron-beam lithography of polymethylmethacrylate, fabrication o ...
This article focuses on activities of corporate foresight that constitute one of the core elements of strategic innovation management. Hence, corporate foresight plays a crucial role for the mid- to longterm competitiveness of firms. It typically comprises ...
Pyrochlore free Pb(Mg1/3Nb2/3)O-3 (PMN) thin films were prepared from mixed-metal precursors solutions using the sol-gel process. Lead acetate [Pb(CH3COO)(2)], magnesium acetate [Mg(CH3COO)(2)] and niobium ethoxide [Nb(C2H5O)5] were used as starting materi ...
In this work we report on solar blind (Al,Ga)N photovoltaic metal-semiconductor-metal (MSM) detectors with a cutoff wavelength as short as similar to270 nm. (Al,Ga)N heterostructures, that allow backside illumination, were grown on sapphire substrates by b ...
The second law of thermodynamics is often expressed as the fact that the entropy of an isolated system increases when a spontaneous change takes place. While this statement is true, a more general formulation can easily be presented to students. Starting f ...
For many years, calorimetry has been recognized as a powerful and universal tool for monitoring chem. and biol. processes. A lab.-scale reaction calorimeter (RC1, Mettler-Toledo), initially developed for chem. reaction studies with a sensitivity of 100-150 ...
In the web context, it is difficult to disentangle presentation from process logic, and sometimes even data is not separate from the presentation. Consequently, it becomes crucial to define an abstract model for business processes, and their mapping into a ...
A review. Scale-up and/or scale-down procedures are crucial during the development of chem. processes. These procedures should be integrated to form a multidisciplinary approach encompassing several branches of science and engineering. The challenge is to ...
A process for prepg. a water sol. polymer comprises: providing a polymn. reaction mixt. comprising one or more polymerizable ethylenically unsatd. monomers; polymg. the ethylenically unsatd. monomers; and adding to the reaction mixt. during polymn. one or ...

To be able to make changes to a business process, it is necessary to understand how the process supports the strategic goals of the business and how changes to the goals may impact the process and vice versa. This paper explains the relations between strat ...
