Porous, graded ceramic structures are of high relevance in the field of energy conversion as well as in catalysis, and additionally in filtration technology and in biomedical applications. Among different technologies for the tailored design for such structures we demonstrate here a new environmental friendly UV curing-based concept to prepare laminated structures with pore sizes ranging from a few microns up to 50 microns in diameter and with porosities ranging from 10% up to 75 vol.% porosity.

Purpose This paper aims to derive tailor-made microtextures for elastohydrodynamically lubricated (EHL) contacts under consideration of manufacturing possibilities. Design/methodology/approach Component tests were used for the evaluation of the influence of surface texturing on the friction behavior in the cam/tappet contact. Furthermore, the manufacturing possibilities and limitations of a combined μEDM and micro-coining process and the feasibility of integration into a forming process were studied. Finally, a methodology based on transient EHL simulations and a meta-model of optimal prognosis was exemplarily used for microtexture optimization. Findings It was found that surface texturing in EHL contacts with high amount of sliding is promising. Moreover, the combination of μEDM and micro coining and the integration into established production processes allow the manufacturing of microtextures with desirable structural parameters and sufficient accuracy. Originality/value This paper gives a holistic view on surface microtexturing over several phases of the product life cycle, from the design, over efficient manufacturing to application-related testing.

AbstractThe regio- and stereoselective dearomatization of indoles is realized for the first time by combining readily available indolyl precursors and electron-rich allenes, namely allenamides and aryloxyallenes. Inter- as well as intramolecular condensations were realized under gold and Brønsted acid catalysis providing a range of densely functionalized indoline and indolenine cores in high yields and excellent stereochemical outcome. Chemodivergent reaction profiles (Micheal-type addition vs. [2+2]-cycloaddition) were realized by a tailored design of both reaction conditions and functionalization of the reaction partners.

Tree work has a high accident rate compared to many other occupations. News accounts of recent accidents can be easily accessed through the internet, though this may not provide a true picture of the number and types of accidents occurring. U.S. government bureaus and agencies have produced reports citing the number and circumstances of fatal accidents in the profession. The government’s information is obtained from many sources and may not accurately identify types or frequency of these accidents. A survey of the accidents and safety training among tree care companies was conducted using a mail questionnaire based on the Tailored Design Method. The company managers responding to the survey overwhelming identified having trained field workers as very important yet only about two-thirds of their companies conducted any training. The training most often conducted was on aerial lifts, chain saws, and chipper, which was provided by company employees in a field setting. Driver’s training was not part of a formal safety program for most of the companies. Aerial rescue was practiced by about one-fourth of the surveyed companies. The most common fatal accidents involved contact with an electrical conductor followed by being struck by a falling limb. The relative number of fatal accidents by event or exposure in this survey was similar to that identified by two federal government reports on fatal accident in the field.
