  1. 1. Molecular insight into ion interactions at charged interfaces exposing sulfonate headgroups

    University essay from KTH/Yt- och korrosionsvetenskap

    Author : Hugo Widehammar; [2021]
    Keywords : Langmuir monolayers; Vibrational Sum Frequency Spectroscopy; Fatty sulfonic acid; Monovalent ions; Poisson Boltzmann theory; Langmuir monolager; vibrations sumfrekvens spektroskopi; fettsulfonsyra; monovalenta joner; Poisson Boltzmann teori;

    Abstract : Hur elektrolytlösningar interagerar med laddade ytor är viktigt för många fenomen. I detta arbete undersöktes samspelet mellan flera joner med en negativt laddad yta som exponerade sulfonat funktionella grupper mot lösning. Särskild vikt lades på deprotoneringsbeteendet vid ytan.

    Keywords : Fluid mechanics; Stokes flow; rigid body dynamics; spheroidal particles; inertia; integral equations; boundary integrals; double layer potentials; quadrature by expansion; Jeffery orbits; linear shear flow; quadratic flow; paraboloidal flow; Strömningsmekanik; Stokesflöde; stelkroppsdynamik; sfäroidiska partiklar; tröghet; integralekvationer; randintegraler; dubbellagerpotentialer; quadrature by expansion; Jeffery-banor; linjärt skjuvflöde; kvadratiskt flöde; paraboloidiskt flöde;

    Abstract : Particle suspensions occur in many situations in nature and industry. In this master’s thesis, the motion of a single rigid spheroidal particle immersed in Stokes flow is studied numerically using a boundary integral method and a new specialized quadrature method known as quadrature by expansion (QBX).

  4. 3. Determining the voltage range of a carbon-based supercapacitor

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Thomas Wells; [2014]
    Keywords : Carbon electrodes; aqueous electrolytes; sodium sulphate; lithium sulphate; super capacitor; EDLC; electrochemical double layer capacitor; EDL; graphite; nano porous;

    Abstract : The focus of this thesis has been to determine the usable voltage range of carbon-based supercapacitors (SC). Supercapacitors are a relatively new type of capacitors with a vast increase in capacitance compared to capacitors which utilize a dielectric as charge separator. A SC consists of two electrodes and an electrolyte separating the electrodes. READ MORE

  5. 4. Six Sigma Approach to Halve the Cycle Time of a Grinding Process on Carbonitrided Parts : Case analysis and solution executed at SKF-Bari Factory, Italy

    University essay from KTH/Industriell produktion

    Author : Valeria Perrelli; [2010]
    Keywords : Six Sigma; Carbonitriding; DMAIC; Process Optimization; Ball Bearings; SKF;

    Abstract : The main purpose of this thesis work was to halve the cycle time of a grinding process of the groove of carbonitrided ball bearings rings. The study was conducted as a Six Sigma project at SKF in Bari, Italy. Reaching the goal was important for the company as it meant avoiding the purchase of another grinding machine. READ MORE
