Biodegradability of Surfactants
ISBN: 9789401045889 / Angielski / Miękka / 257 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The awareness and development of 'biodegradable' surfactants pre-dates current pressures by the environmental movement by nearly three decades, wherein a responsible industry mutually agreed to replace 'hard', non-biodegradable com- ponents of household detergents by 'soft', biodegradable alternatives, without course to legislation. The only requirement at that time was for surfactants used in detergents to exhibit a 'primary biodegradability' in excess of 80%; this referring to the disap- pearance or removal from solution of the intact surface active material as de- tected by specified...

Analytical Chemistry of Synthetic Colorants
ISBN: 9789401045933 / Angielski / Miękka / 212 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. More than one and a half decades have passed since the last book was published describing developments in the analytical chemistry of synthetic colorants. In the intervening period, the scope and technical capabilities of instrumentation for analysing dyes and pigments has significantly expanded. It is now possible to rapidly resolve a number of problems whose solutions were previously either unattainable or very difficult to achieve. For instance, the unambiguous assignment of all the signals in the proton NMR spectrum of a trisazo direct dye, and the confirmation of the molecular weight of...

The Perfume Handbook
ISBN: 9789401050159 / Angielski / Miękka / 323 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In 1948 I was posted, as a Political Officer, to a remote part of south-west Arabia on the edge of the great desert called the Empty Quarter. In valleys made fertile by seasonal flood-waters lay the remains of an ancient civilization. I found inscriptions and the ruin sites of towns, palaces and temples. Almost buried under the sand dunes were the tumbled walls of a great city. From here, two thousand years before, huge camel caravans had trudged their way along 1600 miles of burning sand and rocks to Petra and Gaza, burdened with a most precious cargo - frankincense, myrrh and other perfume...

Electron Crystallography of Organic Molecules
ISBN: 9789401054478 / Angielski / Miękka / 392 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Maximum Entropy (ME) techniques have found widespread applicability in the reconstruction of incomplete or noisy data. These techniques have been applied in many areas of data analysis including imaging, spectroscopy, and scattering [Gull and Skilling, 1984]. The techniques have proven particularly useful in astronomy [Narayan and Nityanada, 1984]. In many of these applications the goal of the reconstruction is the detection of point objects against a noisy background. In this work we investigate the applicability of ME techniques to data sets which have strong components which are periodic...

Electronic Structure of Metal-Semiconductor Contacts
ISBN: 9789401067805 / Angielski / Miękka / 300 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Interface and surface science have been important in the development of semicon- ductor physics right from the beginning on. Modern device concepts are not only based on p-n junctions, which are interfaces between regions containing different types of dopants, but take advantage of the electronic properties of semiconductor- insulator interfaces, heterojunctions between distinct semiconductors, and metal- semiconductor contacts. The latter ones stood almost at the very beginning of semi- conductor physics at the end of the last century. The rectifying properties of metal-semiconductor...

Structure-Property Relationships in Surface-Modified Ceramics
ISBN: 9789401069311 / Angielski / Miękka / 528 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The use of ion beams for the modification of the structure and properties of the near-surface region of ceramics began in earnest in the early 19805. Since the mechanical properties of such materials are dominated by surface flaws and the surface stress state, the use of surface modification tech niques would appear to be an obvious application. As is often the case in research and development, most of the initial studies can be characterized as cataloging the response of various ceramic materials to a range of ion beam treatments. The systematic study of material and ion beam parameters is...

Molecular Basis and Thermodynamics of Bioelectrogenesis
ISBN: 9789401074643 / Angielski / Miękka / 182 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Despite the fact that many years have elapsed since the first microcalorimetric measurements of an action potential were made, there is still among the research workers involved in the study of bioelectrogenesis a complete overlooking of the most fundamental principle governing any biological phenomenon at the molecular scale of dimension. This is surprising, the more so that the techniques of molecular biology are applied to characterize the proteins forming the ionic conducting sites in living membranes. For reasons that are still obscure to us the molecular aspects of bioelectrogenesis are...
