Download e-book for iPad: Monolithic Chromatography and its Modern Applications by Perry Wang

By Perry Wang

High-performance liquid chromatography has turn into the fundamental international separation approach during the last 4 many years. even though, the hot improvement of an alternate column packing fabric - a one-piece porous strong often called a ‘monolith’ - has remodeled the sphere. Monoliths have attracted a large number of curiosity because of the more suitable velocity and thoroughness with which they could separate complicated combos of organic molecules.
Monoliths are porous rod constructions characterised via mesospheres and macro pores. those pores offer monoliths with excessive permeability, various channels and a excessive floor region on hand for re-activity. The spine of a monolithic column consists of both an natural or inorganic substrate and will simply be chemically altered for particular functions. Their particular constitution provides them numerous physico-mechanical homes that allow them to accomplish competitively opposed to regularly packed columns.

In this ebook, international specialists comprehensively describe this constructing box. half I covers the synthesis and characterization of the columns and half II discusses their quite a few applications.

This quantity might be of curiosity to these already utilizing monolithic columns, in addition to those who find themselves new to the world and wish to be aware of extra approximately this technique.

Read e-book online Wir drehen am Klima - na und? (Erlebnis Wissenschaft) PDF

By Gerd Ganteför

Klima – ein heißes Thema, aber used to be wissen wir wirklich? Erfrischend und sachlich nüchtern sorgt Gert Ganteför für Abkühlung in dieser hitzigen Debatte

Der Klimawandel ist nicht aufzuhalten. In weiten Teilen der Bevölkerung und der Fachwelt ist diese Aussage unbestritten. Aber used to be sind die genauen Ursachen? Vor allem, was once kann guy dagegen tun? Die Lösung scheint so einfach und liegt vermeintlich auf der Hand: Die Energiewende muss kommen. Doch ist das im Weltmaßstab überhaupt möglich? Im Angesicht der heutigen globalen Probleme wie Armut und Bevölkerungswachstum schwanken unsere Zukunftsvisionen zwischen absoluten Horrorszenarien und utopischen Träumereien. Auf der einen Seite scheinen wir in dem Teufelskreislauf gefangen, der uns zwingt auf fossile Rohstoffe zurückzugreifen, was once die Klimakatastrophe nur noch beschleunigen würde. Dem gegenüber stehen die visionären Möglichkeiten einer nachhaltigen Lebensweise, die auf Energie weitgehend verzichtet, oder die Entwicklung zu einer hochtechnisierten Welt mit noch höherem Energiekonsum.

Objektiv, fundiert, spannend: Quo vadis terra?

Der Autor stellt sich dieser Frage unbefangen, überrascht mit frischen Ideen und skizziert mögliche Lösungen für die großen Herausforderungen im 21. Jahrhundert. Ausgehend von historischen Betrachtungen und bekanntem Lehrbuchwissen analysiert er die möglichen Szenarien. Ganteför erklärt, warum die Energiewende zu spät kommt, um die Klimaerwärmung noch aufhalten zu können, und gibt mutige Anstöße für eine längst überfällige Wertediskussion. In zwei gesonderten Kapiteln zu Wetter- und Klimakontrolle gibt er einen Überblick über die technischen Möglichkeiten, das Klima aktiv zu beeinflussen, und schließt mit einem Ausblick zu den eingangs erwähnten globalen Problemen.

New PDF release: Climate Change Reconsidered: 2011 Interim Report on the

By Craig D. Idso,Robert M. Carter,S. Fred Singer,S. T. Karnick,Diane Carol Bast,Joseph L. Bast

The United international locations Intergovernmental Panel on weather switch (IPCC), already less than critical feedback for violating the necessities of educational peer assessment and counting on secondary resources, comes below assault back in a brand new e-book co-produced by means of 3 nonprofit examine organizations.

According to weather switch Reconsidered: 2011 period in-between document, normal factors are in all probability to be [the] dominant explanation for weather switch that came about within the 20th and at first of the twenty-first centuries. we're not asserting anthropogenic greenhouse gases (GHG) can't produce a few warming or haven't long ago. Our end is that the facts exhibits they aren't taking part in a considerable function.

The authors of the hot document Craig D. Idso, Robert M. Carter, and S. Fred Singer cross directly to say the internet influence of persisted warming and emerging carbon dioxide concentrations within the surroundings is probably to be useful to people, crops, and natural world.

Both conclusions contradict the findings of the generally brought up experiences of the IPCC.

The ebook is titled weather switch Reconsidered: 2011 meantime file since it precedes a entire quantity that's anticipated to be published in 2013. It makes a speciality of medical learn published on account that ebook of weather swap Reconsidered: The 2009 file of the Nongovernmental foreign Panel on weather switch (NIPCC).

Download e-book for iPad: Advances in Sulfur Chemistry: v. 1 by Eric Block

By Eric Block

Advances in Sulfur Chemistry, quantity 1 presents details pertinent to the 4 key features of sulfur chemistry. This e-book illustrates the nice application of sulfur in natural synthesis as utilized to the synthesis of cyclic compounds, such a lot of which function intermediates within the overall synthesis of normal products.

Organized into 5 chapters, this quantity starts with an summary of desulfurization utilizing Raney nickel. this article then highlights the huge study performed on compounds containing either phosphorus and sulfur connected to a similar carbon atom, revealing synergism concerning those adjoining moment row heteroatoms. different chapters reflect on the numerous category of thiaheterocycles and contain a dialogue of the chemistry of disulfur. the ultimate bankruptcy offers with the chemistry of steel complexes of thiols, with specialise in the chemistry, constitution, and chemical modeling of the nitrogenase enzyme procedure, wherein dinitrogen is eventually decreased to ammonia.

This ebook is a useful source for graduate scholars, postdoctoral fellows, business chemists, and people instructing really good subject matters to graduate students.

New PDF release: Kristallstrukturbestimmung (Teubner Studienbücher Chemie)

By Werner Massa

Aufklarung einer Kristallstruktur bedeutet, die genaue raumliche Anordnung ¨ ¨ aller Atome einer kristallinen chemischen Verbindung zu bestimmen. Aus dieser Kenntnis lassen sich dann fur den Chemiker wesentliche Informatio- ¨ nen ableiten wie genaue Bindungslangen ¨ und Winkel. Nicht nur die genaue dreidimensionale Gestalt und Symmetrie von Molekulen bzw. Baugruppen ¨ wird sichtbar, sondern auch deren Packung im Festk¨ orper. Außerdem erh¨ alt guy implizit Kenntnis ub ¨ er die stoc ¨ hiometrische Zusammensetzung und die Dichte des Kristalls. Da die interatomaren Abstande im Bereich von ca. 100–300 pm oder 1–3 ¨ 1 ? A liegen, sind sie nicht mehr lichtmikroskopischer Untersuchung (Lic- wellenlange ? ca. 300–700 nm) zuganglich (Abb. 1). Wie Max v. Laue 1912 ¨ ¨ erkannte, ist jedoch wegen des dreidimensional geordneten gitterartigen A- baus von Kristallen Interferenz zu erwarten, wenn guy Strahlung mit einer Wellenl¨ ange in der Großenordn ¨ ung der Atomabst¨ ande verwendet, additionally z.B.

Den Vorgang, bei dem ¨ dieseStrahlung—ohneAnderungderWellenlange—amKristallgitterdurch ¨ Interferenz zu zahlreichen in verschiedenen Raumrichtungen beobachtbaren Re?exen abgelenkt wird, nennt guy Rontgenbeugung. Die Methode, diese ¨ Re?exe zu vermessen und aus deren r¨ aumlicher Anordnung und Intensit¨ at auf die Geometrie der Atomanordnung in der Kristallstruktur zu schließen, wird Rontgenstrukturanalyse genannt. Im folgenden Kapitel soll zunachst die ¨ ¨ Beschreibung der Gittereigenschaften von Kristallen behandelt werden, die Voraussetzung fur das Auftreten von Interferenzerscheinungen sind.
