Considering the important changes in the Swiss energy sector, especially in renewable energy(RE)technologies, new revenue possibilities for small and medium sized enterprises(SMEs) emerge. However, the adaption of RE-technologies for Swiss enterprises relies on tangible financial returns, based on complex calculations. This article analyses business opportunities(BOs) of eight Swiss SMEs considering the net present value of RE-investments in an uncertain economic environment. We identify two profitable BOs for Swiss SMEs and three which are not profitable. Further, the article demonstrates that the profitability of such investments remains mostly positive even under economic uncertainties. Surprisingly the profitability does not change significantly if the SME receives a subsidy or not. The support instrument of the Swiss Government has not a ponderous impact on the decision to invest in RE-technologies or not. Therefore, the article emphasizes the importance of including SME in the Swiss attempt to decentralize the energy market.

This paper describes the electroless Ni or Cu plating of some fiuoropolymer substrates through a tin-free activation process. Materials subjected to surface metallization are commercial Teflon() FEP, Nafion(), ACLAR() and LaRCTM-CP1 thin films which have recently gained a large scientific and technological interest due to their excellent thermal, chemical, mechanical and dielectric properties. The original approach implemented in the present work involves: (i)the grafting of nitrogen-containing functionalities on the polymer surfaces through plasma treatments in ammonia, (ii) the direct catalysis of the so-modified surfaces via their immersion in a simple acidic PdCl2 solution (i.e. without using a prior surface sensitization in an acidic SnCl2 solution), and finally (iii) the electroless metallization itself. However, prior to the immersion in the industrial plating baths, the chemical reduction of the Pd+2 species (species covalently tethered on the nitrogen-containing groups) to metallic palladium (PdO) is shown to be a key factor in catalyzing the electroless deposition initiation. This is made by immersion in an hypophosphite (H2PO2-) solution. Wettability measurements and X-ray photoelectron spectroscopy (XPS) experiments are used to characterize every surface modification step of the developed process. A cross-hatch tape test was used to asses the adhesion strength of the electroless films that is shown qualitatively good. In addition, a fragmentation test was developed in combination with electrical measurements. Its use allows to distinguish different adhesion levels at the metal/polymer interface and to evidence the influence of some processing parameters.

Purpose: Elaboration of an indicator to include the dynamic aspect of citations in bibliometric ***/methodology/approach: A new bibliometric methodology—the f^2-index—is applied at the career level and at the level of the recent 5 years to analyze the dynamic aspect of bibliometrics. The method is applied, as an illustration, to the field of corporate ***: The compound F^2-index as an extension of the f^2-index recognizes past achievements but also values new research work with potential. The method is extended to the h-index and the h^2-index. An activity index is defined as the ratio between the recent h'-index to the career *** limitations: The compound F^2 and H-indexes are PAC, probably approximately correct, and depend on the selection and *** implications: The F^2-and H compound indexes allow identifying the rising stars of a field from a dynamic perspective. The activity ratio highlights the contribution of younger ***/value: The new methodology demonstrates the underestimated dynamic capacity of bibliometric research.
