2. 1. Surface modification of inorganic materials with graphene oxide : From solution to high-temperature synthesis

   Author : Simon Tidén; Ulf Jansson; Mamoun Taher; Erik Lewin; Lars Nyborg; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Graphene; Graphene oxide; Coatings; Additive Manufacturing; Laser Powder Bed Fusion; Reactive Hot Pressing; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : The use of graphene as an additive in materials is often challenging due to the agglomeration of the two-dimensional graphene sheets. An alternative additive is graphene oxide (GO), an oxidized form of graphene, which is easily dispersed in water. READ MORE

4. 2. Development of Metal–Organic Frameworks for Catalysis : Designing Functional and Porous Crystals

   Author : Fabian Carson; Xiaodong Zou; Jeffrey R. Long; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metal–organic frameworks; heterogeneous catalysis; nanoparticles; metallolinkers; postsynthetic modification; postsynthetic exchange; Inorganic Chemistry; oorganisk kemi;

   Abstract : Metal–organic frameworks, or MOFs, have emerged as a new class of porous materials made by linking metal and organic units. The easy preparation, structural and functional tunability, ultrahigh porosity, and enormous surface areas of MOFs have led to them becoming one of the fastest growing fields in chemistry. READ MORE

5. 3. The Role of Tetrahedral Building Blocks in Low-Dimensional Oxohalide Materials

   Author : Iwan Zimmermann; Mats Johnsson; Lars Kloo; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lone-pair elements; crystal structure; low-dimensional compounds; oxohalides; Inorganic Chemistry; oorganisk kemi;

   Abstract : The structural architecture found in low-dimensional materials can lead to a number of interesting physical properties including anisotropic conductivity, magnetic frustration and non-linear optical properties. There is no standard synthesis concept described thus far to apply when searching for new low-dimensional compounds, and therefore control on the design of the new materials is of great importance.

6. 4. The Complex Nature of the Electrode/Electrolyte Interfaces in Li-ion Batteries : Towards Understanding the Role of Electrolytes and Additives Using Photoelectron Spectroscopy

   Author : Katarzyna Ciosek Högström; Kristina Edström; Håkan Rensmo; Leif Nyholm; John Owen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; LiFePO4 graphite cell; interface; electrolyte additives; solid electrolyte interphase SEI ; photoelectron spectroscopy PES ; synchrotron; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

   Abstract : The stability of electrode/electrolyte interfaces in Li-ion batteries is crucial to the performance, lifetime and safety of the entire battery system. In this work, interface processes have been studied in LiFePO4/graphite Li-ion battery cells. READ MORE

7. 5. Unsymmetric PCN Pincer Palladium and Nickel Complexes : Synthesis, Characterization and Reactivity

   Author : Abdelrazek Mousa; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Unsymmetric PCN; Palladium; Nickel; Cyclometallation; Carboxylation; Cross-coupling;

   Abstract : New palladium and nickel complexes based on unsymmetric PCN pincer ligands have been synthesized and fully characterized using different techniques. The substituents on the nitrogen side arm of the ligand have great influence on the cyclometallation and the reactivity of the new complexes particularly in case of nickel. READ MORE
