1. 1. Measuring Acoustic Mobility of Particles by Particle Tracking Velocimetry

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Alexander Edthofer; [2022]
   Keywords : acoustophoresis; microfluidics; polystyrene; cells; particle tracking velocimetry; Technology and Engineering;

   Abstract : Acoustophoresis is a method to manipulate and move cells or particles suspended in a medium using acoustic waves. The speed of the acoustophoretic motion depends on the cells' acoustic mobility, i.e. their size, density and compressibility relative to the medium. READ MORE

3. 2. Investigation of acoustic whole blood plasmapheresis for minimization of endogenous blood loss in neonatal care

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Tobias Lindgren; [2021]
   Keywords : Acoustophoresis; peristaltic pump; flow cytometry; plasmapheresis; whole blood; extremely premature infants; Microfluidics; Technology and Engineering;

   Abstract : Early erythrocyte transfusion is common in infants born extremely premature. Research has shown that these children are at greater risk of morbidity later in life, and that iatrogenic blood loss from blood sample analysis is one of the contributing factors to the need for transfusions.

4. 3. Investigation of MEMS-Based Acoustic Levitation for Pick-and-Place Machines

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

   Author : Alejandro Bergstrand; Lukas Malm; [2021]
   Keywords : Mechatronics; Acoustic levitation; Pick and place machine; Standing wave levitation; MEMS; Acoustic traps; Surface mount electronic components; Mekatronik; Akustsik levitering; Pick and place maskin; Stående våg; MEMS; Akustiska fällor; ytmontering;

   Abstract : The standard technology used in a pick and place machine for lifting and transportingsurface mount electronic components is a vacuum based solution.  This thesis investigates a new acoustic based technology for manipulating surface mountelectronic components. READ MORE

5. 4. Evaluation of OSTE-hybrid materials for acoustophoresis applications

   University essay from KTH/Medicinteknik och hälsosystem

   Author : Elin Forss; [2020]
   Keywords : Acoustophoresis; off-stoichiometry-thiol-enes; OSTE; microfluidics;

   Abstract : This project aimed at exploring new hybrid materials to be used for acoustophoresis applications. Acoustophoresis can be used to manipulate particles inside a microfluidic channel by creating ultrasound standing waves within the channel [1]. This can be used for cell separation [2] or trapping of particles [3]. READ MORE

6. 5. Transient Plasma Photonic Crystals - A Route Towards Slow Ultra-intense Light?

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Robin Weissenbilder; [2018]
   Keywords : slow; light; plasma; photonic; crystal; transient; ultra-intense; short; pulse; laser; Physics and Astronomy;

   Abstract : Periodic electron and ion density modulations in near critical density plasmas induced by counterpropagating femtosecond pulses of intensities on the order of 10¹⁵ to 10¹⁶ Wcm⁻² are described in a linear and stationary regime and investigated using particle-in-cell simulations in one and two dimensions. The periodic gratings produce transient plasma photonic crystals lasting up to several picoseconds with ultra-wide angle-selective band gaps on the order of Δω/ω₀ ≈ 10-20%. READ MORE
