Lipase thesis

X Philip Ye, Svetlana Zivanovic Abstract Chemo-enzymatic synthesis of unimolecular polymeric micelles UPMs is proposed for their potential utilization as drug delivery vehicles in dilute aqueous solutions. The UPMs are star polymers consisting of a hydrophobic core and hydrophilic corona.

Both the exterior cladding and the polyisocyanurate insulation are now considered as the main reasons for the rapid spread of the fire. Both economical as well as environmental considerations demand for high-performance building insulation materials to reduce global energy requirements for space heating and cooling.

At the same time, devastating events like the Grenfell Tower fire, which broke out in in West London causing 72 deaths, highlight that besides low thermal conductivities, insulation materials must be fire retardant and robust even under extreme conditions. Targeting this, researchers from the University of Science and Technology of China Hefei have now successfully manufactured a composite aerogel material which excels in both these categories.

Synthesis of the gel matrix consisting of an inorganic SiO2 network and a polymeric PFR network see Figure on the right was achieved via the so called chitosan templated method. First, the precursors TEOS, acetic acid, and phenol were solubilized in an ethanol water mixture, which was then added to an aqueous chitosan solution, before adding formaldehyde.

Lastly, the hydrogels were solvent exchanged with acetone before being supercritically dried with CO2, resulting in the final composite aerogel. Astonishingly, the PSi aerogel retained its monolithic structure even after 30 minutes of flame exposure see Figure below, g and h.

Moreover, while only the white SiO2 network was left on the directly exposed front side, the sample maintained its structural features on the backside to great extents.

Photography of the back side g and the front side h after the fire resistance test. In summary, the authors conclude that their novel aerogel is a promising candidate for next-generation insulation materials, as it unites great mechanical stability and fire retardant properties with outstanding characteristics in terms of thermal insulation.

While certain challenges regarding economic scalability and rentability are still to be overcome, phenolic-silica aerogels surely seem very auspicious from a technical perspective alone.

Zhi-Long Yu et al.Moisture, pH, and lipase activity were followed during fermentation. Statistical analysis of the results was performed to evaluate the effect of the studied variables on the maximum lipase activity.

OhioLINK ETD: Deiuliis, Jeffrey A. Chinese hamster ovary CHO cells are one of the most commonly used cell platforms to express mAbs and recombinant therapeutic proteins. With the availability of the CHO-K1 and Chinese hamster genome sequences, these tools allow for the rational design of CHO cell engineering through sequence-specific approaches.
