  1. 11. Development of an analytical method for the screening of meaty flavors in commercial foodstuff by SPME-GC/O-MS

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Ioannis Protopappas; [2021]
    Keywords : Gass Chromatography; Mass spectrometry; Meaty flavors; Aromas; Solid pahse microextraction; Mallaird; Lipid degradation; Food technology; Agriculture and Food Sciences;

    Abstract : The aim of the project was to develop a methodology for the chromatographic analysis able to identify the key odorants in meaty food products. The approach was based on the analysis of an already in market product and the theoretical background of the meaty flavors sensorially. READ MORE

  3. 12. SPME Method for Chemical Analysis of Heavy Organic Trace Compounds in Synthesis Gas

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Constancia Felise Elemia Freire; Simon Edin; Chang Ho Lee; [2020]
    Keywords : ;

    Abstract : There currently exists no commercialized method for rapid sampling and analysis of trace tar ingas streams. Solid phase microextraction (SPME) with a polydimethylsiloxane (PDMS) solidphase has been previously investigated as a possible candidate due to its solvent-free natureand reusability. READ MORE

  4. 13. Diffuse correlation spectroscopy for estimation of coagulation thickness : a phantom study

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Zeyneb Alsadi; [2019]
    Keywords : DCS; Diffuse correlation spectroscopy; Biomedical optics; coagulation; phantom study; coagulation depth; coagulation thickness; diffusion; model; two layer model;

    Abstract : The objective of this preliminary study was to determine the potential of diffuse correlation spectroscopy (DCS) for assessment of coagulation depth. Coagulation of tissue can occur due to a number of different reasons such as thermal or electrical burns or radiofrequency ablation. READ MORE

  5. 14. Endeavors toward Novel Cochlear Implants from Stretchable Printed Circuit Board Technology

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Rickard Viik; [2019]
    Keywords : novel; cochlear; implant; electrode array; electrode; stretchable; soft; electronics; pdms; polydimethylsiloxane; liquid; alloy; galinstan; hearing aid;

    Abstract : Profound sensorineural hearing loss is at the present time a major worldwide health concern, affecting over 5% of the worlds' population. Through cochlear implants (CI), treatment of sensorineural hearing loss now offers the possibility to restore hearing function through electrical stimulation of auditory nerves. READ MORE

  6. 15. Silicone-based Carbon Black Composite for Epidermal Electrodes

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Melika Eklund; Nellie Kjäll; [2019]
    Keywords : cPDMS; cAgPDMS; epidermal electrodes; silicon based composite; carbon black poltdimethylsiloxane;

    Abstract : A method of synthesizing silicone-based composite consisting of carbon black (CB) as a conductive ller in Polydimethylsiloxane (PDMS) was developed. The aim was to nd a cost eective and easier method to fabricate stretchable, epidermal and conductive electrodes in striving for inexpensive real-time health monitoring. READ MORE
