1. 1. The Origins and Ecology of Early Paleozoic Spreiten Ichnofossils: Comparisons of Daedalus and Syringomorpha with Alectorurus

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Zane Goodell; [2023]
   Keywords : trace fossils; ichnology; Cambrian; Daedalus desglandi; Alectorurus circinatus; Syringomorpha nilssoni; the agronomic revolution;

   Abstract : The Cambrian explosion not only shaped the ecosystems of the Phanerozoic, but fundamentally changed how biota interacts with the environment, including the substrate. Cambrian trace fossils Alectorurus and Syringomorpha as well as Ordovician-Silurian Daedalus represent novel modes of faunal interaction with the newly innovated shallow marine mixed-ground and have surprisingly limited stratigraphic ranges.

3. 2. Review of pH recommendations for soilless cultivation systems

   University essay from SLU/Dept. of Crop Production Ecology

   Author : Elric Fabricius; [2023]
   Keywords : soilless cultivation; hydroponics; aeroponics; NFT; nutrient film technique; DWC; deep water culture; pH; nutrient solution; speciation; availability; biomass production;

   Abstract : Our human population is growing, and with that, so is our demand for food, food that today still is not a guarantee for all of us. To help increase global food security, the diversification of our food production through the implementation of soilless, hydroponic cultivation systems has been suggested. READ MORE

4. 3. Chromia-Alumina Thin Films from Alkoxide Precursors : From Precursor Synthesis to Deposition and Characterisation

   University essay from Uppsala universitet/Oorganisk kemi

   Author : Elina Elvelo; [2023]
   Keywords : alkoxide; synthesis; thin film; coating; alumina; chromia; spinodal decomposition;

   Abstract : A hetero-bimetallic alkoxide CrAl3(OiPr)12 was synthesised through metathesis of achromium(III)chloride THF complex (CrCl3 . 3 THF) and 3 KAl(OiPr)4.It was used as a single sourceprecursor to make oxide powders and films with 1:3 chromium/aluminium compositionthrough sol-gel synthesis.

5. 4. Assessing the effectiveness of siloxane-based flame retardants

   University essay from KTH/Kemiteknik

   Author : Josefin Eklund Wallin; [2022]
   Keywords : Polyhderal oligomeric silsesquioxane; POSS; PVC; TGA DSC; DSC; thermal properties;

   Abstract : Polyedrisk oligomer silsesquioxane (POSS) är molekyler som har en inorganisk ryggrad med organiska grupper fa ̈sta utan på. Själva kåren har en bur liknande form och har en hög termisk stabilitet tack vare kisel (Si) och syre (O) som den består av. READ MORE

6. 5. 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.
