1. 1. Nitrogen fixation in wheat (Triticum aestivum) : effect of Azotobacter salinestris CECT 9690 on N-accumulation

   University essay from SLU/Dept. of Soil and Environment

   Author : John Pålsson; [2023]
   Keywords : Biostimulants; Vixeran; N-uptake; N-concentration; yield; cereals;

   Abstract : Biostimulants are products that can improve nutrient availability, nutrient uptake, nutrient use efficiency and tolerance to abiotic stress with the aim to increase plant growth and yield. During the last decades, the interest in, and market for biostimulants has grown and is expected to have a large compound annual growth rate. READ MORE

3. 2. 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.

4. 3. Development of heat recovery solution for heavy duty truck cabs to improve energy efficiency.

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Exekiel Aurelio; Rahul Acharya Rathnakar; [2022]
   Keywords : air-to-air heat recovery; air-to-liquid heat recovery; integrated thermal management system; heat wheel; heat pump; battery electric vehicle; battery electric trucks; energy savings.; luft-till-luft värmeåtervinning; luft-till-vätska värmeåtervinning; integrerat värmehanteringssystem; värmehjul; värmepump; batterielektriskt fordon; batterielektriska lastbilar; energibesparingar.;

   Abstract : The recent climate actions to reduce greenhouse gas (GHG) emissions have set the stage for decarbonizing the transportation sector through electrification, which has led to a surge in the deployment of battery electric vehicles (BEV). Trucks are no exception, which has led automakers to shift their focus toward producing Battery Electric Trucks (BET). READ MORE

5. 4. Optimizing Control Algorithm for Indirect Liquid ThermalManagement of Batteries : A Study Executed at Northvolt

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Mantas Petrosius; [2021]
   Keywords : ;

   Abstract : The vast expansion of intermittent sustainable energy generation has favoured a gradual adoption of lithium-ion batteries in various industrial and automotive applications. Despite its many inherent merits, this storage technology is very vulnerable to temperature variations: the performance and lifespan of LIBs are substantially influenced by their load cycles, thermal behaviours, and operating temperature range.
