1. 1. Exploring alternative surfactants to replace PEG within lipid nanoparticles

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

   Author : Elina Edidovica; [2024]
   Keywords : Lipid nanoparticle; polyethelyne glycol PEG ; alpha-tomatine; N-hexadecyl beta d-maltoside HDM ; DOPC; DPPC; cholesterol; film hydration; stability study; DLS; Cryo-TEM; SAXS; pharmaceutical formulation; Chemistry;

   Abstract : Over the past decade an increasing amount of studies has demonstrated that PEGylation not only precipitates reductions in drug delivery efficiency but also triggers the immune system to produce antibodies, specifically anti-PEG antibodies. The objective of my thesis is to explore alternative surfactants that could viably replace PEG within lipid nanoparticles. READ MORE

3. 2. EFFECTS OF COMMERCIAL NANO-LIME PRODUCTS AS A CONSOLIDATION METHOD FOR WALL PAINTINGS An experimental case study

   University essay from Göteborgs universitet/Institutionen för kulturvård

   Author : Hannah Petrini; [2023-11-07]
   Keywords : wall paintings; Dalby Church; nano-lime; consolidation; Nanorestore®; Nanorestore Plus®; conservation of wall paintings;

   Abstract : Some of the main deterioration problems concerning wall paintings is structural degradation of the wall painting and the flaking of the painted layer. Consolidation, both in the form of reinforcement of the rendering of the wall painting and the re-adherence of a flaking paint layer to the underlying substrate, have thus been an important part of conservation efforts concerning wall paintings.

4. 3. The effect of material properties on PEM fuel cell catalysts on durable oxidation reduction activity

   University essay from KTH/Kemiteknik

   Author : Xiaoling Jiang; [2023]
   Keywords : PEM fuel cell; catalyst; ORR activity; particle size; degradation; PEM-bränslecell; katalysator; syrgasreduktionsaktivitet; partikelstorlek; åldring;

   Abstract : I detta examensarbete utforskas påverkan av partikelstorleken hos Pt-katalysatorer på kolbärare på syrereduktionen i polymerelektrolytmembran (PEM)-bränsleceller. Den elektrokemiskt aktiva ytarean, aktiviteten för syrereduktion och tillhörande degraderingshastigheter för de undersökta katalysatorerna beräknas och jämförs. READ MORE

5. 4. Optical properties of water absorbing textiles for camouflage

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Eveline Örtenberg; [2023]
   Keywords : Camouflage; SWIR; Water; Nanocellulose; CNF; Textiles;

   Abstract : Background matching, a form of camouflage, involves species developing patterns and coloration that closely resemble their environment. Humans have utilized camouflage and background matching, particularly in military applications, to reduce detectable characteristics, known as signatures. READ MORE

6. 5. Testing aerosol vertical profiling methods with portable instruments on unmanned and manned aircraft

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Ellen Grace Soroka; [2023]
   Keywords : Physical Geography; Ecosystem Analysis; Aerosols; Vertical Profile; Black Carbon; PM2.5; Nanoparticles; UAV; Drone; Master degree thesis; 30 credits in Atmospheric Science Biogeochemical Cycles; Earth and Environmental Sciences;

   Abstract : This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. READ MORE
