In this chapter, we present the basic concepts of the low-energy electron diffraction (LEED) and reflection high-energy electron diffraction (RHEED) experiments. The main goal is to provide an overview of the exploitation of these instrumental methods for analyzing the surfaces of technologically important III–V compound semiconductors. In particular, the interpretation of LEED and RHEED patterns

In this chapter, we first elaborate on the discussion of the nature of CKEs that has taken place in the previous chapters in the book. Secondly, we summarise the main lessons we have learnt about CKEs from the studies reported in this book. Thirdly, we identify and analyse what circumstances and conditions promote creativity in organisations and which ones hinder it. We also identify some of the m

The lean stability limit of a prototype syngas burner is investigated. The burner is a three sector system, consisting of a separate igniter, stabilizer and Main burner. The ignition sector, Rich-Pilot-Lean (RPL), can be operated with both rich or lean equivalence values, and serves to ignite the Pilot sector which stabilizes the Main combustion sector. The RPL and Main sectors are fully premixed,

A fully mobile remote-sensing system based on the lidar principle is described. With this system, atmospheric probing using Mie scattering, differential absorption, or Raman techniques can be performed yielding information on atmospheric pollutants or general atmospheric parameters. The system incorporates a powerful Nd:YAG laser pumping a dye laser and is equipped with a fixed Newtonian telescope

The long poem Skördarne (The HArvest) by johan Gabriel Oxenstierna (1750-1818) was an attempt to do for the Swedish what Virgil had don for the Roman Countryside in his Georgics. However, "georgic poetry" was seldom recognised as a distinct genre by the classical system of poetics, and its relation to neighbouring genres were often unclear. The present study seeks to place Oxenstierna's poem in th

Vi lärare på Litteraturvetenskapliga institutionen vid Lunds universitet har länge saknat ett arbetsmaterial när vi undervisat i hur man utför epikanalyser. Det har visat sig att Claes-Göran Holmbergs och Anders Ohlssons Epikanalys. En introduktion har fungerat utmärkt som lärobok och på ett enkelt sätt utrett de många teorier och metoder som kan utnyttjas i en analys. Men våra erfarenheter av epi

Molecularly imprinted polymers (MIPs) are artificial plastic materials that mimic antibodies or enzymes. Like natural antibodies or enzymes, molecularly imprinted polymers can selectively bind target molecules or can promote catalytic reactions. In contrast to these natural entities, they are robust materials that resist heat, harsh chemicals and the presence of organic solvents. The starting mate

Canonical bases, also called SAGBI bases, for subalgebras of the non-commutative polynomial ring are investigated. The process of subalgebra reduction is defined. Methods, including generalizations of the standard Gröbner bases techniques, are developed for the test whether bases are canonical, and for the completion procedure of constructing canonical bases. The special case of homogeneous subalg
