1. 1. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

   University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

   Author : Shivang Parmar; [2023]
   Keywords : Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

   Abstract : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. READ MORE

3. 2. Developement of a numeric tool for fatigue life evaluation of the regulating mechanism in Kaplan runners

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Emil Treitler; [2022]
   Keywords : Fatigue; Kaplan; Hydropower; Turbine;

   Abstract : Kaplan turbines are a type of hydropower turbine with adjustable runner blades. This allows the turbine to alter its power output while maintaining a relatively high efficiency over a wide range of power levels. But these frequent blade angel adjustments exposes the turbines internal mechanism to wear and the possibility of fatigue failure. READ MORE

4. 3. Synchrotron X-ray Tomography Study of Bone-implant Integration

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Ornella Lohéac; [2021]
   Keywords : Bone-implant; Digital volume correlation; Micro-computed tomography; PEEK; Synchrotron; Technology and Engineering;

   Abstract : Implant loosening is a recurring problem in the field of orthopedics, typically resulting in a physical and financial burden for the patient. Proper integration of orthopedic implants within host bones is a fundamental requirement for the successful function and limited risk of failure of implants which, in-vivo, must support various loading conditions.

5. 4. Detection of voids in welded joints using ultrasonic inspection : Quality control of welded joints in copper canisters for purpose of permanent storage of used nuclear waste

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Bakhtiar Afzalan; [2021]
   Keywords : Ultrasonic inspection; Nuclear waste; Nuclear waste storage; welded joints;

   Abstract : This thesis was done i cooperation with SKB Clab in Oskarshamn and studies use of sonic waves for detecting voids and irregularities in the weld joints of copper capsules used for long term storage of radioactive waste. Since these could pose material failure and thereby risk radioactive contamination of ground water it is very important to find means of quality control before storage. READ MORE

6. 5. Study of the Resistive Switching Mechanism in Novel Ultra-thin Organic-inorganic Dielectric-based RRAM through Electrical Observations

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Alba Maria Martinez Garcia; [2021]
   Keywords : Resistive random-access memory RRAM ; flexible electronics; organic-inorganic hybrid dielectric; dual-mode conducting filament; electrical programming; Resistivt slumpmässigt åtkomstminne RRAM ; flexibel elektronik; organisk-oorganisk hybrid dielektrikum; dubbelt läge ledande glödtråd; elektrisk programmering;

   Abstract : The promising role resistive random-access memory (RRAM) plays in the imminent reality of wearable electronics calls for a new, updated physical model of their operating mechanism. Their high applicability as the next-generation flexible non-volatile memory (NVM) devices has promoted the recent emergence of a novel ultra-thin (< 5nm) organic/inorganic hybrid dielectric RRAM.
