Cobalt Nanoskeletons: One-Pot Solution Synthesis of Cubic Cobalt Nanoskeletons (Adv. Mater.

ADVANCED MATERIALS, Issue 16 2009
16/2009)
Cubic Co nanoskeletons with an edge length of 100 nm can be prepared by a facile one-step solution method. In work reported on p. 1636 by Ying Ma, Fangli Yuan, Jiannian Yao, and co-workers, CoO nanoparticles of ,10 nm are subjected to self-aggregating, in situ reduction, Ostwald ripening, and facet-selective coordination-assisted etching to form these novel structures, which exhibit excellent magnetic properties. Simple control of the shape can be achieved by altering the reaction time. [source]

Fabrication of Periodic Microstructures in Pentaerythritol Triacrylate Through Femtosecond Laser Interference Two-Photon Polymerization,

ADVANCED ENGINEERING MATERIALS, Issue 7 2009
Andrés Lasagni
Fabrication of periodic, two-dimensional microstructures in pentaerythritol triacrylate (PETIA) is demonstrated through femtosecond laser interference patterning. Planar arrayed structures of different periodicities and geometries were fabricated using three, four, and five interfering beams from an 800,nm ultrafast femtosecond laser. The periodic topography can be varied from isolated conical pillars to interconnected cellular structures by simple control of the interference pattern in combination with energy dose. [source]

The cover picture by Lasagni et. al shows two-dimensional periodic microstructures of polyethylene glycol diacrylate (PEG-DA) fabricated using nanosecond (top) and femtosecond (bellow) multibeam laser interference patterning (MLI). The periodic topography can be varied by simple control of the interference patterns as well as exposure dosages. Such structures with controlled topography are of relevant importance for applications in biomedical devices. [source]

The quality profession and its role in the world,

QUALITY ASSURANCE JOURNAL, Issue 3 2003
Navin S. Dedhia
The concept of quality evolved from inspection, measurement, and testing, which had been in practice for many, many years. Long ago, an artist or a sculptor took pride in his work and as a result always tried to excel in what was created. Mass production systems brought the concept of inspection by someone other than the craftsman in the first half of the 20th century. Application of statistical control came later as a result of World War production methods. Quality as a profession and the managerial process associated in the quality function was introduced during the second-half of the 20th century, and has evolved since then. No other profession has seen as many changes as the quality profession. The quality profession grew from simple control, to engineering, to systems engineering. Quality control activities were predominant in the 1940s, 1950s, and 1960s. The 1970s were an era of quality engineering and the 1990s saw quality systems as an emerging field. Like medicine, accounting, and engineering, quality has achieved status as a recognized profession. Published in 2003 by John Wiley & Sons, Ltd. [source]

Reconsidering the Northwest European Family System: Living Arrangements of the Aged in Comparative Historical Perspective

POPULATION AND DEVELOPMENT REVIEW, Issue 2 2009
Steven RugglesArticle first published online: 12 JUN 200
During the past four decades, historians and demographers have argued that historical Northwest Europe and North America had a unique weak-family system characterized by neolocal marriage and nuclear family structure. This analysis uses newly available micro-data from 84 historical and contemporary censuses of 34 countries to evaluate whether the residential behavior of the aged in historical Northwest Europe and North America was truly distinctive. The results show that with simple controls for agricultural employment and demographic structure, comparable measures of the living arrangements of the aged show little systematic difference between nineteenth-century Northwest Europe and North America and twentieth-century developing countries. These findings cast doubt on the hypothesis that Northwest Europeans and North Americans had an exceptional historical pattern of preference for nuclear families. [source]
