1. 1. Investigating self-discharge in a graphite dual-ion cell using in-situ Raman spectroscopy.

   University essay from Uppsala universitet/Strukturkemi

   Author : Ismail Yussuf Hassan; [2023]
   Keywords : graphite; dual-ion battery; parasitic reaction; cathode-electrolyte interface; anion intercalation; concentrated electrolyte; self-discharge; Raman spectroscopy;

   Abstract : Anion intercalation in the graphite positive electrode of a dual-ion battery requires high potential (> 4.3 V vs Li+/Li), which aggravates parasitic reactions involving electrolyte decomposition and Al corrosion, manifesting in poor coulombic efficiency, cycle life, and quick self-discharge.

3. 2. Standardized Test Methods in Over-the-Air Chambers for FCC Part 27

   University essay from Umeå universitet/Institutionen för fysik

   Author : Oskar Hellström; [2023]
   Keywords : ;

   Abstract : Base stations (BSs) are the cornerstone that enables wireless communications. In order for a new BS variant to be imported and sold in the US they are required to undergo electromagnetic compatibility (EMC) testing. This testing is necessary to obtain their Federal Communications Commission (FCC) certification. READ MORE

4. 3. EMC-Optimized Transparency: Reducing Electromagnetic Emissions in Surveillance Camera Domes

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Fabian Sondh; Erik Hansson; [2023]
   Keywords : Technology and Engineering;

   Abstract : Electromagnetic compatibility (EMC) is a crucial aspect to product development. Companies need to make sure their products live up to the standards that exists around the world. One way of reducing electromagnetic emissions is to shield the product, using some conducting material, for instance, copper. READ MORE

5. 4. Electromagnetic Compatibility (EMC) test in an Open Area

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Nair Samira; [2023]
   Keywords : EMC; EMC Aircraft; EMC Spacecraft; EMC standard;

   Abstract : Electromagnetic compatibility (EMC) is a very important and increasingly relevant technology in use and is closely related to many technologies such as automobiles and aerospace industry technology including aircraft and spacecraft. Achieving electromagnetic compatibility between equipment inside the device is more than necessary to avoid the problem of interference leading to serious problems. READ MORE

6. 5. Development of a Novel Method for Automotive On-board Transmitter EMC Immunity Testing

   University essay from Uppsala universitet/Elektricitetslära
