Direct Joining and Debonding on-Demand of Polymers through Surface Modification and Metal Ion Interaction AuthorROMAN GÜNTHER Year2023 SourceDISS. ETH NO. 29321 LanguageEnglish 2842LUMiFraLFrachis work focuses on the development of a novel method for joining and residue-free separation of polymer surfaces that support polymer recycling and enables the bonding of incompatible polymers. The technology presented employs polymer surface modifi- cation to generate functional groups that enable reversible joining through intermolecu- lar interactions between two rigid 11 more macroscopic polymer surfaces.Notablynot only substrates of the same polymer but also PS and PA 12which are incompatiblewere joined with this method. The adhesion between the substrates was determined using a LUMifrac apparatus. The adhesion strength increased with in- creasing bonding temperature and when both substrates were plasma-treatedreaching adhesive strengths up to 5.5 ± 1.7 MPa. Remarkablythe joint substrates could be rap- idly de-bonded on-demand simply by treatment with waterand the separated sub- strates could be re-bonded by renewed plasma treatment.

Diese fundamental angelegte DOE-Studie zeigte eine breit wirksamesehr effiziente Emulgierfähigkeit dieses bio-basiertennicht-ionischen Emulgatorsder durch Reaktion von Pentose (Xylose) mit Fett-Alkoholen hergestellt wurde. Als DOE-Parameter wurden der Emulgatoranteil von 0.2 bis 4% und der Ölphasenanteil von 10 bis 40% in Anwesenheit einer kleinen Menge an Xanthangummi variiert. Im ersten Teil der Studie wurde die optische Klarheit der Emulgator/Öl-Mischungen bei verschiedenen Temperaturen (70oC bis 30oC) gemessen.

The emulsifying performance of a sustainable oil-in-water emulsifier named EcoSmooth ™ APP- 5000 Formulation Aid (proposed INCI name: Myristyl/Stearyl Xylosides (and) Myristyl alcohol (and) Stearyl alcohol) was thoroughly characterized/studied using high throughput research (HTR) workflows and design of experiment (DOE) tools .This fundamental design of experiment study revealed the broad emulsification efficiency of this biobased non-ionic emulsifier made from reaction of pentose (xylose) with fatty alcohols. The DOE parameters studied were the emulsifier percentage varying from 0.2 % to 4 % and the oil phase percentage varying from 10 to 40 % in presence of a small percentage of Xanthan gum. During the first part of the studythe optical clarity of the emulsifier/oil phase blends variants were measured at different temperatures ranging from 70 ºC to 30 ºC. The data generated allowed to make the ternary phase diagram showing the optimal emulsifier concentration relative to the specific oil phase studied. Fundamental experiments have also revealed that dispersion of the emulsifier in the oil phase prior to emulsification leads to generation of lamellar phases which provide a steric barrier to droplet coalescence and promote long term emulsion stability. The stability of the multiple emulsions was controlled with a LUMiSizer equipment. More details EditionForum for Innovation Internal reference2858 Open publication →

Firstit was found that ionomers neutralized with smaller-sized cations led to better dispersion of asphaltenes in heavy oil. Secondionomers neutralized with smaller-sized cations were observed to slow the asphaltene aggregation process.

Reducing the particle size of drug powders to a few hundred nanometers is a well-known method that leads to an increase in solubility due to an elevated total surface area. However 11 more state-of-the-art comminution techniques like cryo-milling suffer from degradation and contamination of the drugsparticularly when sub-micrometer diameters are aspired that require long processing times.

Howeverits appliance as a nutraceutical ingredient is hampered by its volatilityirritating odorand easy absorption in the stomach and small intestine. A chitosan solution containing propionic acid was dispersed in a palm oil/corn oil mixture with polyglycerol polyricinoleate (PGPR) to form PA-loaded water-in-oil (W/O) emulsions. The stability of the emulsions was improved by the inclusion of both chitosan and palm oilwhere the chitosan reduced the emulsion particle size and palm oil increased the viscosity. The thermal volatility and storage stability of the encapsulated propionic acid were significantly improved due to the stability of emulsion structure and hydrogen bonding between chitosan and propionic acid. pharmaceuticalmedicinemedical More details EditionIssue 12 Internal reference2903 Open publication →
