Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Using a synthetic approach to organic materials chemistry, this book sets forth tested and proven methods and practices that make it possible to engineer organic molecules offering special properties and functions. Throughout the book, plenty of real-world examples demonstrate the countless possibilities of creating one-of-a-kind molecules and supramolecular systems to support a broad range of applications. The book explores applications in both materials and bioorganic chemistry, including molecular electronics, energy storage, sensors, nanomedicine, and enzyme engineering.Organic Synthesis and Molecular Engineering consists of fourteen chapters, each one contributed by one or more leading international experts in the field. The contributions are based on a thorough review and analysis of the current literature as well as the authors' firsthand experience in the lab engineering new organic molecules. Designed as a practical lab reference, the book offers:Tested and proven synthetic approaches to organic materials chemistryMethods and practices to successfully engineer functionality into organic moleculesExplanations of the principles and concepts underlying self-assembly and supramolecular chemistryGuidance in selecting appropriate structural units used in the design and synthesis of functional molecules and materialsCoverage of the full range of applications in materials and bioorganic chemistryA full chapter on graphene, a new topic generating intense researchOrganic Synthesis and Molecular Engineering begins with core concepts, molecular building blocks, and synthetic tools. Next, it explores molecular electronics, supramolecular chemistry and self-assembly, graphene, and photoresponsive materials engineering. In short, it offers everything researchers need to fully grasp the underlying theory and then build new molecules and supramolecular systems.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- In this chapter, it is first shown how a number of steps in the scientific process in this field of chemistry can be improved by naming and understanding the topology of three-dimensional networks and can be the coordination polymers, metal–organic frameworks, or hydrogen bonded systems. Specifically, the discussion is centered on the use of network analysis and graph set analysis to (i) understand the products we get, (ii) compare these materials to what others have made, (iii) communicate our results to colleagues, and (iv) truly make something new by design. The topology symbols by O'Keeffe, Wells, and others are introduced, and the reader is given a step-by-step guide on how to obtain the topology of a 3D net. Finally, graph set analysis is introduced, and its utility in supramolecular chemistry and network analysis discussed.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Processes occurring at surfaces and interfaces are very important in environmental systems, necessitating surface-specific characterization tools that can help us understand processes at and specific properties of surfaces and interfaces, and their role in biogeochemical systems. This chapter describes the use and application of X-ray photoelectron spectroscopy (XPS) to study interfacial processes of relevance for geomicrobiology. Examples are given from studies determining cell wall composition, acid–base properties, cell surface charge, metal adsorption onto bacterial cells, and bacterial surface–induced precipitation of secondary minerals. As XPS is an ultrahigh-vacuum technique, several sample preparation methods have been applied to enable analysis of bacterial samples, including analysis of freeze-dried samples as well as frozen bacterial suspensions. These are described and discussed alongside advantages and disadvantages of different approaches, with a special focus on fast-freezing and the cryogenic technique.

Quantum Darwinism and entropy
- 2022

Ingår i: Advances in Quantum Chemistry. - Cambridge : Elsevier. - 9780443186653 ; , s. 297-321
-
Bokkapitel (refereegranskat)abstract
- In this chapter we will highlight and broaden the concept of Quantum Darwinism to incorporate an extension to thermodynamic open systems. The strategy will be a bit different compared to the conventional approach in that the formulation, rather than offering a fundamental discussion of the classical measurement problem, derives a more general steady-state picture, where ultimately the dissipative organization of the quantum system is properly thermalized and spatio-temporally tuned from first principles. Two cases will be discussed: (i) the human brain and (ii) the black hole. Both are treated as open non-equilibrium systems, where the brain, conjugate to the mind, exhibits negentropic gain, and a thermo-qubit syntax for communication. The second example, a quantum analogue of a black hole, is demonstrated to exhibit Hawking radiation including the explicit connection between the black hole surface area and the entropy. The results are derived from the axiomatic structure of pioneering quantum chemistry with rigorous extensions to open system adaptation in the Schrödinger-Liouville-Bloch formalism at steady state conditions. The approach suggests a prolegomenon for Hilbert's sixth problem.

- There is no simpler compound than water. It is the most copious substance on Earth and the most important constituent for life, as we know. There is also a continuous scientific interest due to its exceptional and infrequent properties, such as a density maximum at 4 ℃ (at atmospheric pressure), a high specific heat capacity, and a low viscosity under high pressure, among other macroscopic properties. The origin of the unusual properties of water is evidenced at lower temperatures in the no man’s land temperature region (235–150 K), where bulk water cannot remain in an amorphous state. Instead, in this region, bulk water crystallizes in a complex phase diagram with more than 16 crystalline phases. Therefore, most of the work done so far on supercooled water focuses on the investigation of the dynamics when crystallization is suppressed using different types of confinements, such as nano-cavities or by mixing water with other solutes (polymers, proteins, or DNA). On the contrary, in this chapter, we will use broadband dielectric spectroscopy to analyze the dynamics of aqueous solutions and confined water when it is partially crystallized, i.e., when liquid water and ice coexist. With this technique, it is possible to obtain information about the molecular relaxations in both amorphous and crystalline phases. We have analyzed the results of this semi-crystalline water and compared them with the response of supercooled water in fully amorphous solutions. Finally, we discuss the implications of these results on the behavior of bulk water.

Self-Assembly at Interfaces

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Due to the microscopic size of single-molecule components, it is impractical to assemble a large number of single-molecule components via direct top-down manipulation. Instead, self-assembly methods, meaning spontaneous ordering and organization of molecules without direct human intervention, are proposed as the most feasible way of building up multiple single-molecule devices [1]. The self-assembly process is directed by weak interactions. In this chapter, we will introduce the basic concepts of self-assembly and put it into a context of single-molecule electronic devices. We will discuss mechanisms of formation of self-assembled monolayers and how typical single-molecule components interact with surfaces. Finally, we will present some recent developments in electrode materials using single molecules.
