1. 1. Michael additions utilizing transition-metal-catalysts, Scope and limitations

   University essay from Lunds universitet/Kemiska institutionen

   Author : Ruben Hansson; [2023]
   Keywords : Green chemistry; transition metal; rare earth metal; Michael addition; Yb; Zr; Hf; analytical chemistry; Chemistry;

   Abstract : The effect that organic solvents have on the environment and the intrinsic risk that come with using them should be limited. By replacing organic solvents with less harmful solvents, such as water, and with more effective catalysts can risks intrinsic to organic solvents be minimized or eliminated. READ MORE

3. 2. Uptake and retainment of radionuclides in edible mushrooms – from fruiting to cooking

   University essay from

   Author : Delshad Mansour Ayoubi; [2022-12-06]
   Keywords : Medical physics; Activity concentration; Transfer coefficient; Dose;

   Abstract : Purpose: The purpose of this study was to study the uptake, distribution and transfer of Mn-54, Zn-65, U-238, U-235, U-234, and Po-210 in mushrooms and their respective caps and stalks, the effects of chelates and ligands, and the potential release of radionuclides during a cooking procedure. Introduction: Fungi are organisms that are composed of a fruiting body (mushroom) and tubular hyphae, that branches out into complex networks called mycelium. READ MORE

4. 3. Green Protein Hydrogels and Non-dry Aerogels in Water Purification

   University essay from KTH/Kemi

   Author : Emanuel Nelsson Vedung; Alexander Singh; Julia Wadefjord; [2022]
   Keywords : Aerogel; Hydrogel; Whey Protein Isolate; Water purification; Adsorption; Sustainability;

   Abstract : Having access to clean water is not a certainty for every human being. Today, there are major problems with polluted water that not just affect us humans, but also the ecosystem around us. In recent years, research into making aerogels from protein nanofibrils (PNF) has increased. READ MORE

5. 4. Electrochemical Behavior of the High Entropy Oxide (Mg,Co,Ni,Zn)1-xLixO (x=0,35)

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Rasmus Sandström Kinnane; [2022]
   Keywords : high entropy oxides; lithium-ion battery; x-ray diffraction; scanning electron microscopy; cyclic voltammetry;

   Abstract : Today's society is currently developing lithium-ion batteries to eventually replace the use of fossil fuels. High entropy oxides is a new type of material to use as an anode in the lithium-ion battery. These high entropy oxides may consist of a few different transition metals including lithium and oxygen.

6. 5. Investigation of stability in high salt polymer electrolytes for sodium batteries

   University essay from Uppsala universitet/Strukturkemi

   Author : Fengnan Yuan; [2022]
   Keywords : ;

   Abstract : Poly(trimethylene carbonate)–sodium bis(fluorosulfonyl)imide system shows a promising performance as polymer-in-salt electrolytes. The polymer electrolytes with salts concentration from 62% to 71% were tested through DSC, FTIR, EIS and constant current cycling. The solubility of the salts varies in different salts in PTMC.
